 I think I'm like... Hello, okay. Yes. I see whether I'm alive. Don't lie. We shall try. Okay. You're right. I don't know whether I'm alive or not. Let me go check. That's true. Ooh, there it is. I can see it. I can see it. Okay. What happened yesterday when we left? We cannot hold meetings or watch live from their seat. And everybody was just chatting on the live stream. And even people in the room was chatting on the live stream. It was a bit bad for the speaker. The speaker is speaking and everybody is looking at her. So I'm chatting on the live stream. What are these? So distracting. You can see your face, who are reading. Hi. Then... There's a lot of chairs here. Grab a chair. Okay. We're doing a little live stream as well. So in case... So later on when we do the... So later on... We'll try our best to... We'll try our best to... Hello everyone. I'm behind Genius SG. You can find me on Twitter. Got Kodak Nguyen Phu. Someone who faces, I guess. Hi, what did you want to try? Start by introducing yourself. Hi, how are you? That's it. Cool. Hi, I'm Rizan here. Hi Rizan. Hello, I'm Jin Wei. I decided to come at the last meeting. Thank you, Jin Wei. Nice to meet you. So Wei is... Also one of our volunteers at Genius SG. So she will be... She also runs a few meetups. Namely React Knowledgeable. Check it out. It's a pretty cool site. And we also... She also helps out with the top CSS, which is the CSS Meetup in Singapore. So... Yeah, and... She has been helping out as a volunteer with our meetups as well. A brother with a meetup recording. And we trained her at the last training session. So now she is helping me as a teaching assistant. Yeah. It's cool. Hey, Ro. Hello. There's so much CSS you can grab or you can grab from the... I got this one. And also can... So I'm also doing a little live stream. So in case people who wants to... Okay, so... Alright. So... Is it okay if I start? Alright, cool. So the format for the training usually is I'll go through some slides, give some overview and context about Genius SG, what we do, and how we do our magic. And then after that there will be a hands-on session where you try to set up one of our recording systems. I will show you. As you see later when I go through the slides, we have a very specific system where we are kind of like... I will need to figure out how to use. You'll see me on some of our volunteers at our meet-ups. You'll see how... A lot of moving parts. But essentially it's quite a few... Three basic things that we record, which is the screen, the presenter screen, the presenter himself or herself, and then the voice. There's just three things that we record. And so our system is kind of optimized to kind of do it as long as you can go all three recordings and then you can upload the files at the end of the day. So that's essentially our workflow. So I will go through some of the things we do and how we do our things and then you will have a hands-on session on how to actually set up our recording system. So, yeah. So sure you get started. And cool. Right, so again that's me. You can find me on Genius SG or you can find me on Twitter at Hoi Kung Thu. I think you can also find me on Instagram with this handle as well. Anyway, so Genius SG is a not-for-profit community initiative that I created a few years ago to kind of document the Singapore tax scene and the start-up scene. You'll see a lot of videos that we have with a lot of start-up and tech related videos. Mostly tech meet-ups. Our first ever recording was in 2013. In the meet-up that I ran it's called the PHP Music Group. So this was 2013. You can see it's really good. I've been doing this for quite a few years. Five, six years. Too long. Anyway, while we were creating Genius SG was created to answer the question where are the engineers in Singapore? So, Genius SG 6 would be a place where everyone gets to know, learn the tech community, the Singapore tech community. So it's like anyone who is new to the tech community can go there and see the different talks that are happening. It's also a learning resource for people who can't make it for the in-person meet-up. And also I hope it's a place where people can also discover the meet-up groups in Singapore. So as you go to the video you'll find a link to the meet-up page or the event page where you can get more materials about the speaker, the community, as well as join the meet-up group and maybe continue on with the meet-up in the future. So it's what is the way of helping meet-up groups publicize themselves. So essentially I really want this to be a place where people who are curious about the tech community or the tech in Singapore can just go there and have a good sense of what it's like and the people that are there and also to help people and the engineers that they're looking for. Hopefully jobs as well. So on the side you'll find a curated list of videos that we record of the tech meet-up scene. Some of them, this is a very outdated slide but this is just a sampling of some of the meet-up groups that we record and some of them are no longer in existence so we really should update this one soon. There was a GIT meet-up in Singapore as well so many years ago. Anyway some of the stats on our website now with about 3,000 plus videos with about 13,000 subscribers on our YouTube channel. Our website gets 18,000 page views per month. Our YouTube channel gets about 36,000 views per month. So far we recorded in upwards of 40 conferences more than 40 yet. So last year we actually recorded quite a few GIT-CAM, GIT-CAM, we will record Asia Summit which I think you spoke there and PyCon, SG and iOS Con was the last meet-up or other conference I've ever recorded and also POPACON and two others. So there's a lot of grassroots tech events. There's also some international events that we record like Vox Days and we also record I guess you can find a whole bunch of them API days is something that we recorded. So I think they're coming here again this year. So far we've trained about upwards of 70 plus volunteers but actual active volunteers is less than 10 because people have different priorities and work life gets in the way or work and life gets in the way. So this is our website, it's very simple. Yeah and there's also a donate button at the top where you'll feel like you want to help contribute to us. Our YouTube channel some accolades the people has given to us. For example, when we covered the iOS conference a few years back one of the speakers, Ben Asher by the time he landed in San Francisco the videos were already out. So he left the conference he flew back like the day after and by the time he landed in San Francisco the videos were already online. So they kind of like speaks to our workflow. You compare to a lot of other video sharing or video recording things they tend to be a bit more slower. But anyway then again the speed isn't everything so they are okay there's a live stream so anyway. Okay so for those of you on the live stream hello, you can hear me sorry we'll try to do some post-production one thing anyway yeah whatever it is yes let's go on. So how do we do what we do? Very simple one thing we try to do is streamline our capture workflow in order to do that we want to capture all the inputs like the video, the screen capture and audio at the same time so that we don't lose any of these things and it is also critical to just keep them in sync because if the slides are going faster then they are talking or the video and the moving lips are audio and moving lips are not in sync it will also be weird a lot. So we try to feed out the source into a laptop via USB and the software video mix so we have a software video mixer that lets us record stream and edit the video feed at the same time so we usually just do the recording and editing in live you can also stream because the software we use is open source software and it allows you to stream on Facebook, YouTube, Twitch it's a pretty powerful software used by gamers to Twitch their gameplay it's called OBS Studio so you can check that out OBSproject.com so anyway, so we do at the end of the day there is no full video post production so all the things come in we mix it live and we upload it at the end of the day and the video files are then ready to be uploaded at the end of the session so one of the secret source that we have is that we have a volunteer website where volunteers go in and upload the videos which makes it a whole lot easier to publish the videos so I'll share with you a little bit about that later ok cool ok cool, thank you sorry for the distraction don't get too distracted right in any case here we are so right and also nothing so once you got permission from the meet up we put your name in the schedule that we know that you want to go record the meet up and then we will basically designate a set for you to pick up so try to pick up the recording set like a day before or the you know the person who is holding on to the set the tag before you can go to the same meet up and pick up from the person as well so it's also possible so anyway, so yeah usually we will pick up from the hacker space so that's where we can't store most of our gear there are also a few sets which are kind of permanently semi-permanently there's a deployed somewhere which I'll share a little bit about later and of course try to reach the meet up at least 30 minutes before so because you need time to set up and to test the recording and test the video feed and all that stuff so make sure you're there like maybe 30 minutes before that's the recommended time with a trained hand or experienced person you can probably start the recording in 10-15 minutes but if you're new to this you want to make sure that you have time to get adapted to it and stuff like that so anyway, so post meet up the file is less than 1.5 gigabytes which means I think usually meet up recordings will be about 30 minutes top you should be able to the file should be about 200-300 megabytes which is can upload to our site quite easily so for that just copy out the file into a thumb drive and then upload to the volunteer site which is there so the website so anyway the website is called is upload.engineers.sg and the video should then appear on Engineers.sg within the hour and you return the set if possible and also inform the telegram group so there's another telegram group where people can get involved with and kind of get to know each other make a meet the other volunteers in the Engineers.sg so now real resources that we have so as a volunteer you can check out our resource on Git we have this little site where you can go to get a bit more information about the way that we do things so in the Git wiki you will find that quite the description of how we do our stuff what kind of file that we use some helpful script that we use more important to you is the volunteers guidebook so this guidebook is probably something I will go through with us in the short while as we are recording as we are doing the live training later right so in the guidebook we talk about the stuff that's in the in the set so there's a packing list and there's also a visual guide of how we can actually connect all the things which is quite useful created by Donna she was a co-organizer of hackware before and also one of our volunteers so she drew this visual guide which is quite nice anyway there's also setup procedures which I will go through again so we can go through this together and also schematic of how we do the recording so yeah so I will go through that again so we can start recording what to do what to look up for we start recording and troubleshooting that's the most important thing how do we troubleshoot things to go wrong Murphy's law things will go wrong and of course I'm loading to and Genesis G there's a few options right so yeah and then we did have a video tutorial I guess this live stream will now be our new video tutorial and you want to contribute to our website we also have our website hosted as a report on github it's a Rails app so you can go look it up on the website it's also a Rails app and the thing that we use to do our recording is this software called OBS OBS Studio so it's open source it's free so basically you can download and kind of like get it running on your Mac on your windows yeah we do it we use windows mainly because even media our screen capture to the driver for it works best with OBS on windows or there's no there's no Mac driver that works with OBS for that device which is kind of sad anyway so this is a pretty popular software around for a couple of years we started using it when it was in early phases like before it was called OBS Studio it was just called OBS and it did a massive rewrite of the code base to make it more stable and stuff so yeah it's been quite stable so far version 24 right now anyway yeah so I'll go through the steps for setup later with you as we go through the hands on and some of our teams in action when we first started out we were just a single camera set up so we only one camera recording a screen plus a speaker and all that stuff and we'd get very blur quality screens the first conference we ever recorded is GeekCam in 2014 so yeah that's our first conference our typical setup is something like this with cameras and microphones all over the place video camera pointing at the speaker during conferences we do have a bit more we use a more powerful camera because usually the camera is a bit far further away from the speaker so we have a high quality so we can zoom in and out from a distance so for conferences we usually roll this out we roll out the big guns for conferences but anyway we don't use this we don't usually use this for normal meetups because our setup is quite optimized for small rooms and stuff like that anyway the screen capture tool that we use is called even media live here in Portable and we do all the mixing in windows and this is how the software looks like when it's in operation so you can do like this is the screen that is being recorded so as you lay it out it is recorded this way and then you can switch between different scenes which I'll show you a bit later on so yeah audio recording sometimes you can use a condenser microphone or you can use a wireless lapel which I think was used by our lapel wireless lapel mic this is one of the lapel mics that we use sometimes we use a sound mixer but only one set has this so you don't worry about using it I think it's at SPD right now nevermind and in the past we also used Zoom H1 audio recorder as a backup audio so that in case you have no experience with windows windows can crash so we want a backup in case things do crash or sometimes during the recording something's happened and we have to restart the computer or the audio gets affected somehow so we need to have a backup system so our backup for audio we have a backup for audio and a backup for video so I'll show you how our backup system is so the audio case is usually has gone through quite a lot of evolutions when it first started out it was a shopping cart like this but the shopping cart broke after two outings so it was like damnit so we invested in suitcases that looks humongous these are all hand-me-downs from my mom and some other people that bought the pink luggage anyway but nowadays we use something a bit more classy which is a suitcase that over here I'll show you how it looks like later anyhow sometimes you do have a cable management problem because we do have a lot of cables so be careful when you are recording and so what's in our bag we have a lot of things in our bag but this is one of the special things that we keep along with our stuff so video converters are very important things so you want video converters to work with any presenters laptop you can place all these out later on and some of our volunteers in action oh sorry oh we're back anyway so once again one of the perks of being a volunteer engineer is that you can get work for conferences almost for free I think if you are a volunteer you can definitely go for free but our downside is that you do have to work so you basically set throughout the taking recording so yes that's us so you can find us on all these spaces and telegram group as well you can find telegram I'll show you this a bit more later but now let's go into the practical part is there any questions any questions oh good so you came late can't no worries anyhow so now we'll go into the practical part of the session so we'll go through a little bit about this setup so let me bring up the set now maybe we can can we see can we see the set yeah so this is one of our recording sets I think we can move the camera let's try and move this to the other angle line up okay sorry this is a bit distracting okay okay cool okay so this is usually what we carry around so it's like a suitcase that we move around and it's all our stuff that we need for recording so I'll just go through it the front part is very cool all our converters okay another set I'll just upload everything inside okay so in our set you'll find we have a lot of cables HDMI cables and here is the bag of converters so this is what we use to connect to any kind of that pop out there you'll find that we have an equipment organiser so we have all our sets all our equipment critical equipment is out there we have a laptop we use hand made down set pre love full work spa HP workstation split power extension cord we have a camera here this is our backup system so we have a camera that we put at the back of the room that is pointed at the screen records the screen and the audio of the of the event so that we would not lose anything if the plane laptop crashed so we use this as a backup so I'll probably show you that later this is a tripod for the backup system put that here first there's also a tripod over here and this one is attached to the top of suitcase this is for the webcam so we use we're connected to the webcam so that it is power supply for this guy that's about it I think there it is anyway so first thing we do this is our packing list we got the packing list done visual guide we'll go through that later so as a volunteer first when you reach the place where the recording equipment take note of where the video cable is so in this case we'll be using that cable for for the screen and then take note of where the nearest power point is take note of where so take note of where the power point are and where the HDMI cable for the location is so in our case here the cable is here and the power strip is here we can probably do our set up somewhere around here so let's assume I was up over there so make sure that I'm kind of in between this too so if there's a venue have a place if the venue have a table so for people like this then do ask for the table then you put all our stuff there and if you can't get a table then use a chair so use a very sturdy chair so that you can put some power strip so we just go through this so it might be helpful to have this printed out so some of our sets we do have it printed out so you can actually refer to it if you need to if you don't know that I think some of the sets might have been taken out or something or thrown away or forgot or misplaced but anyway we do print it out so you can kind of refer to it if you need to otherwise yes you should afford to refer to it so first of all so make sure the power so it's kind of important to make sure this is only used by you because you never know what happens if someone else comes over or can I charge my phone and then in doing so they accidentally turn off the wrong switch they'll be quite devastating so yes trying to do that okay so anyway alright make sure there's power so there are times when I could set this up and it was like wow very good no power or forgot to turn it on so yeah one of those little things right next is to set up the htmi splitter and htmi cables so the cables and htm the splitter itself I'll show you the thing now is please our equipment organizer where I put where I put all of our our main equipment here so it's the equipment organizer because there's more all the all the important things all put together in one little package so first of all set up the splitter splitter looks like this so this is velcro you can chuck it out so here's the htmi splitter so our whole system is htmi so you need to have the htmi make sure that the venue also have htmi if they don't have we do have converter but I'll go through that later so first of all splitter set it up there's one input two output so and the power for that is here so let's power it up so there's one input and two output so the cables to set up would be to make sure the presenter can send an input to me and then have one that goes to the projector itself right so and let's try to get the cables that we need I think it's here so the first cable to set up is between the presenter laptop and the screen so if we just connect from there yeah we'll make sure we'll get it back on so this one connect to that and right here right so it goes into here so once you connect this, the LED will turn on so you know that you're getting a signal next is to connect this to this guy and hopefully lights up lights up wow it should appear on the screen hopefully okay cool right yay yeah so it's kind of important to get this part working first because you want to make, you want to assure the presenter and the middle organizer that they can still at least present right so right so this case I'll set up first and there will be another cable here this one so this short one will go to our screen capture tool I'll connect that in a while so basically one of it will go into our screen capture tool right over here so screen capture tool has an input so connect it to the input okay right next thing to look at this is so that the presenter and organizer can check the laptop are compatible with our setup as well as projector's resolution if it's not realistic to keep the splitter on the equipment organizer can remove it and reposition it elsewhere so what I've done is I've taken it out of the equipment organizer and kind of like put it on the table so that it's easier to get more things around so place the laptop where you use this laptop so place it at a place where it's easy to where you can start to operate it so I'll put it on the table here actually when we do record at a hacker space sometimes I would probably put it on that table instead so because the HDMI signal going through here gets routed to the ceiling and down there somewhere so that's where it gets dropped down point but anyway for today we'll just be testing simulating testing over here so it might go too fast okay right so right so place the laptop do not switch it on yet and then connect the charger so there's a big sticker there connect all USB before starting the laptop so do not turn it on until you connect all the things next thing to do is to set up the tripod and webcam the tripod is over here usually you want to put it on the floor open this up lock the legs in place so it's extended and then extend it so it won't extend the middle part you can secure it as well by turning this so this thing can be extended further if you need to so yeah there's quite a few things you can extend so webcam is in this bag so this bag itself has the webcam as well as our wireless microphone so this is the transmitter it's a TX there so it's what we presented on the web and then the receiver is down here and I'll put it on the organizer okay I'll just connect this first so set up the tripod and webcam so you notice all our USB ports USB connectors actually have a sticker there's a color sticker even this particular thing here has a color sticker so all of them have three colors which are green, blue and brown and you find on the laptop itself there are also three corresponding sticker colors there green, blue and brown so you will never connect to the wrong place hopefully and there's a color line anyway brown goes here right and okay so that's done then connect and set up the equipment organizer so this guy kind of puts it on the table usually I'll put it around next to the laptop so it's easier for me to check on things and stuff like that so first can you screw up the screen can you screw up the page right so set up the equipment organizer connect all the USB cables with the blue, green and brown dots connect the micro USB charger to the wireless microphone receiver so the receiver is here and then the cables are all here so you find the cables with the colors make sure they're connected properly so the blue one connects to the blue one this is the blue one goes here and it connects to the focus right which is our audio interface green so make sure the green one is connected here and here and the next thing to do is the USB charger so this the receiver itself doesn't need batteries it just needs to be powered by a charger so just need to connect that it should come on in front you see the front there it's just starting and then connect the HDMI cable to the screen capture 2 which I have done right so this is the guy the screen capture 2 this will be connected to the HDMI cable right so then set up the wireless microphone and transmitter the transmitter itself is here itself in the region side there is a little bag like this where we keep the microphone so this is the power mic so just connect this and there's a screw here as well you can kind of like screw in to the which will which will keep it quite secure later on when you do the hands on you can try it out and to power up the thing just press and hold on the power button over here just press and hold on there press and hold you'll find your light up right once the light up you'll see on this on the receiver side you will also kind of light up and tell you that it's connected to the TX so over there there's a battery indicator for the TX which is the transmitter so if it's 3 bars it means it's full charged so just be mindful about the battery so you will speak and do it you'll see that this audio the thing that the section in the middle will start going up 1, 2, 3, 4, 5 so it goes up one notch anyway so it tells you the channel which is channel 8 so that's the wireless speaker our wireless microphone so check on switch it on check the battery levels which is over there you can see the battery level on the receiver the auto interface will also light up with the green rings okay I'll now turn on the power of the laptop then once the laptop is started you can start OBS so all the devices here all the USB devices are powered by the USB power so webcam is powered by USB the audio interface over here gets powered by USB as well as the screen capture too right? so the part that says the audio interface should light up green so when I speak into this right you will see that there's a green circle that lights up when I speak into it it means it's getting an audio signal it's getting audio signal from the receiver you see the green bar if it goes red it means it's too loud if it's too loud going in then it's not good the audio that you record will be distorted with a lot of popping and crackling sound so you usually want to bring it down to around the green zone so if there's no audio it will be no light when there's receiving audio it will be green so it's kind of nice to see visually and then you can adjust the volume sometimes during the meet up you might get a speaker who is very soft then you need to add some boost to boost the gain a bit boost the audio level and if there's a very loud guy speaking then you probably want to bring it down to the softer so it's you have flexibility as an operator we get okay right any questions so far if there's a speaker that once in a while he speaks loud and mentally doesn't solve it we have software to kind of compensate for that so so yeah start the laptop and then now you can start OBS OBS studio is actually on the desktop there's a little icon over here so just double click on that first time you start you take a while to appear so just let it do its thing it's loading itself in the memory so once it's up then you can probably see all the things we talked about right okay cool right so this is OBS so OBS itself is it's a Windows software so that's you can see recording anyway so I'll just do a quick introduction of OBS and what's in there so the top screen is actually what is being recorded right now right and on the left hand side there we have a collection of of scenes the scenes are basically the arrangement of the different things right so like the first scene is called PIP picture in picture so it's a white screen and has a white screen middle capture of the of the of the presenter screen and and then it has a small little web web cam capture at the bottom left hand corner right and medium medium video means I adjust the portion of the tool so that you can get like in this cases we usually use this if the speaker has slides which has very big fonts then you can see more of the speaker speaking right does it stay for the whole duration whenever you click so you stay like this and what if halfway through the if I click transition as well so you can see our videos we do record we do switch between different scenes to kind of optimize the view so like for example we usually switch to this one the picture in picture with larger video during the Q&A so Q&A session we probably the last slide on the presenter screen is probably just his email address and something like they want to see more of the speaker like talking and answering questions that's more for this situations where the presenter has a white screen slide you have like square 4x3 slides let me just try and demo that quickly so I will now bring up a keynote slide which if it's something like this see the full the full presentation there's everything there but if you have a presenter which has something like this you will see that there's a black black column on both sides so that's when we switch to the 4x3 so that we can see more of the we basically remove the black bars on the side then we have 4x3 there are two different arrangements 4x3 as well so they can see different arrangements ok once it's there are also others this one again is the same as the other one where we do Q&A then we want to see one of the presenter answering questions screen only is at times where we do have like coding set more of code that is writing code or showing code for example you're looking at some piece of code here so you can use this to to basically show more of the person typing your code so there's also video only so you want to just see the presenter or the team or whoever is giving the talk right also a few others that we added in underneath so let me just resize this pressing the wrong button right so follow us sometimes I put this for fun we don't actually use this black you want to fade to black move it out to the end and fade to black there's a little side by side which is a bit interesting so we have a situation where the speaker is probably like standing here like so right and he's stationary he doesn't move around he's like just giving a talk maybe he has his laptop in front of them then you don't really need to so you can actually narrow the video view and then have more so you have equal proportion to the person speaking as well as the screen I've seen this technique we use in Apple Keynotes you will notice it's only good if the person stays stationary if the person starts moving around like this then you'd like to start to follow by turning the camera if you try to turn the camera right now try to follow me it's not very smooth so if we do get that we'll bring back to this instead to have a wider thing there's something we use is a picture-in-picture overlap this too is the more traditional picture-in-picture it's the more traditional one that we use so you will have a place where the person the presenter himself is doing more of the coding but right now for example in this case our power explorer window is not really it doesn't really have important information, the important information is probably on the right hand side over here but you still want to see the file names and everything so it's okay to overlap the bottom left hand corner there are times where we also want to maybe the part of the code is also a bit more more important stuff is on the left hand side we can also do this as well or we can adjust it to the bottom if we want to so like this so just do note that wherever I just drag and drop around it's also being recorded so yeah but there is a way to do it without showing up all the things so on the left as you can see the different arrangements we call them scenes so as you're recording the meetup of the person you can actually adjust or switch to different scenes as and when it suits is suitable otherwise on the right hand side of this is the sources so you see the three different things that goes into the source which is first of all the background the background with the engineers actually logo and the gray color band and then there's a webcam as a source so this is one of the bottom left and the screen capture which is this one so I've actually locked the webcam and the background but the screen capture is still unlocked so you can actually adjust it and move it around resize it if you want to so for example in the case of overlap the screen capture is locked but the webcam is not so I have the freedom to even resize it if I want to if I want to okay so the part in the middle is the audio mix so as the speaker is speaking usually for the clip on mic you want there's a clip here usually on a clip so the mic king up a person it's most important to keep it as close to the throat or the mouth as possible so they can really get good capture so there are a few types of view that we record people with a round neck t-shirt some of them like to clip it on their shirt like this this one is okay but I think the best is still around the collar so what I do is I'll pinch a little bit of the t-shirt the collar then make sure I clip into the t-shirt then it actually sits up here so as I'm recording speaking right now it's recording me so it goes so the top bar is green so if it goes it stays in the green zone green to yellow zone is probably the best audio so if I adjust this a bit more I'm still a bit soft so I go a bit more hello checking 1 2 3 fast 1 2 there's also this guy here sorry it shouldn't be too low fast 1 2 2 2 so if it stays in the green to yellow zone green to yellow zone is probably the best you see the first bar so as I'm speaking in a normal presenter voice it should be green to yellow zone and that would tell me that there's a good audio capture it is too loud like I'm doing now hello testing it goes in the red zone means it's too loud and it may end up recording a distorted voice you see this top one yeah so it's important to check this and this so make sure they're both in the green make sure it's green and here it's either green to yellow zone if it's too loud then it's not good because you record very picky and distorted voice so it's not very nice it's not very nice on listeners also so another thing about mic'ing up you're mic'ing up a person who is wearing a polo tee like yourself so usually I'll just clip on the you can come over and demonstrate yeah so one way to do is just around this side I'll just clip around here this is also a good place to yeah so this is roughly the place I can clip it up and then for ladies for ladies it's a bit a bit more tricky because they're very addressed so for ladies because they're very addressed it can be a little bit of a problem because not all dresses have pockets so it's impossible so they may have to hold on to it hold on to their hand just put your hand as I infer it then insert it yeah so do you have an engineer's sg? no he's not here yet you have a seat at the front there's a few seats there nothing there's a sofa here if you want to discuss it as much as possible in front of the bookcase there's a sofa there anyway you will mic'ing up a lady who is wearing a dress roughly the same plate area which is around the dress on the collar or around the neckline where as for the transmitter it's a bit of a tricky thing for a guy like us we can put it in our pocket or back pocket so it's quite easy for ladies they may hold it in their hand which is going to give you a big trouble if you are doing a clicker and this one as well so some ladies they can just clip it on their belt and for guys as well we can put it on our belt the most extreme I've seen is a lady would actually clip this on your bar strap that's a bit extreme but she did it anyway so whatever it is when we're mic'ing up a lady make sure they're comfortable just let them know especially that you're doing this or if it's better just hand it over to them you feel uncomfortable so close to them just let them have the microphone piece and they can clip on themselves there are some presenters because they are nervous and they have so many things they need to multitask on they may not be able to pay attention to you so if you go up to them and say may have permission to mic you up then you can help them do that if they are sure about how to mic themselves up and they will use them seasoned presenters will just take it and they just take it to the best place that they know they will get captured there are some presenters are also quite particular about the look when they are presenting so those presenters will go even to the extreme of putting it through their t-shirt or through their shirts so here it's not exposed so I probably need to disinfect this anyway but yeah so this is the techniques for mic'ing up a person so make sure that it's important that they are miced up before they start recording because if you don't get miced up you can't audio you can't whatever so there are also situations in venues where they are and when you also give them a handheld or wireless microphone for the place so in those situations do remind the presenter that this is for the recording only right so for the house audio application they still need to hold on to the handheld mic to do that so they will need to have both in some extreme cases they have to hold on to two wireless mics invest in stuff which have pockets yes people with pockets will benefit from this but during conferences we actually do tap into the conference venues audio system so that the presenter will need to hold on to one mic so that we don't have to worry so much like when we did the POPERCON at the MiniBaseSams we actually talked to the AV guys at the venue and we set up one of our recorders in the sound room so what happens is in the sound room we are giving an audio from our transmitter to our receiver so it basically it's the same sound over here but here instead of being connected to being mic'd up to the presenter we actually connect this to the sound system so that the sound system gives us audio and we send it to us but that's more for the conference setup so you don't have to usually don't need to worry about that because you know I'll usually be there usually to do training about that as well in the future anyway for monthly meetups meetups and record this should be good enough to get things started and of course when we can go back to the setting so next you can start and check so you can ensure that the video feed is from the webcam and you can screen capture stuff right make sure that yes and then try to do a test recording so start recording is very simple just click on the start recording start recording button over there so I'll try to mic myself up right there's a big start recording button start streaming start recording so usually we won't be streaming so just start recording so this is me speaking as my presenter voice and my presenter volume so I'm talking to people hello testing one two three la la la so this is once you do that you can click on stop and then to see the video recording just kind of file and show recordings show recordings you bring up this and you can really see the latest recording is usually at the top in this case it was ok ok so audio because the playback is still set to the old let's check this so you don't hear an audio just right click on this playback devices make sure that the speaker itself is set as the default because right now it's trying to send audio back there but we don't need that ok so once you got that try again it's muted no wonder so again this is a test recording to make sure that we can capture the screen as well as the audio and all that ok yeah so yeah that's the basics of recording what else is there so so recap presenters laptop goes out to our splitter our splitter to so output one to the projector one to our thing and from there's also the wireless microphone from the transmitter to the receiver receiver goes into the focus right audio interface which then goes into our laptop webcam is direct connection to the laptop should be good yeah and once it's recorded you will hear in the recordings folder which we can then upload right and to start recording so let's go to the next part ok start recording so once you launch the OBS you should see the laptop started before you start recording help the presenter where the wireless mic help presenter to connect the laptop make sure so there's two of the things that you do to help presenter connect the laptop connect to where the mic and also to yeah check if the screen capture is ok whether it reflects the current screen so we want to make sure that it's not frozen so if you try and scroll up just scroll a little bit I can see that it actually moves so it means it's not frozen so it's good so we just adjust this back to one of the number ones like this right so if the capture is good make sure the video is ok make sure the audio level is ok ok optional but good to try and try before any presenter to do a short recording so to make sure that you are recording things to start recording this screen to start recording it's ok to start a little bit earlier because it's ok to capture a little bit of extra in front it's better to have extra than to to start the recording mid-sentence right and also once it clicks start there is a half of split second or half a second of lag between you cooking it and the actual recording persisting to the disc so it's ok to start a little bit earlier right make sure the presenter is always in view of the video feed follow them around with the webcam if it moves around so if you are very lucky you have a presenter who stays stationary you will find presenter keeps walking left and right that's what I'm doing now we call them walkers you will find those I'm a walker yes so you will find those make sure this thing can turn left and right if you want to capture this right so usually during the Q&A we will try to either switch to video only so that we can just capture this speaker talking and gesticulating and presenting stuff or answering questions and of course at the end of the presentation after the presentation don't remember to stop the recording because you want to record one file per speaker and then we start recording after the first speaker is done and then once the second speaker is up and all connected and ready to go then we start recording the second speaker and then troubleshooting ok so the most common problem that happens is the screen capture may freeze so if you are recording this it's fine you can still so if you are showing presentation slides you may be presenting at slide number 5 but on the screen it's still a slide number 3 that means the screen has some problems and you need to fix it so the way to fix it there are a few possibilities of why it's happening because for possibility A capture buffer needs to be reset so to do that, let's go to the sources window the screen capture double click on that there's a button called de-activate so you deactivate the thing and then activate again to reset the video capture buffer that in 90% of the situations will fix the problem or sometimes it's a bit stressful the torque is going on and it freezes so get familiar with it so the next thing to do is the next possibility is the hdmi splitter has signal issues so this guy usually this is very reliable but sometimes it may have problems so one way to fix that is to pull out the hdmi cable connected to the splitter power cycle this thing so I'll just demonstrate right now so first of all what I can do is turn it off first and pull all the cables okay and then connect the cables one at a time so first of all connect the power the first thing to connect is the presenters presenters cable first so you see the reality light up next thing to do is connect to the projector make sure you can get a signal through there and it should light up soon so once that is done then the last thing you do is connect to our screen recording and then restart do that deactivate activate again kind of a dance that usually solves the problem also it's about power cycling this guy and getting all the things back in right so possibility C you need to do a hard reset of the screen capture 2 so do a hard reset it's just to pull out the plugin pull out the plugin you may need to and the last possibility is if something has gone wrong with the computer you need to restart so just restart OBS if that doesn't work restart the computer that usually solves the problem but unfortunately if you are in the middle of recording then you will reboot the computer you lose a few minutes of footage so that's unfortunate which is why we have a backup system so then I'll set way to our backup system right the other part I'll finish the trauma training part first audio is suddenly off so basically this guy as you are using it sometimes if you accidentally press the power button it goes red and you will actually muted the system so you will see now there's actually no signal going in and there's no green ring over there so basically the possibility B so speaker accidentally muted the microphone so to unmute it you have to go to the speaker and ask him to press this again which would usually solve the problem and now see the green green light going on so another way you can actually do this is to actually go to the receiver you look at the receiver side on the left hand side there are two buttons one of them is to unmute try to find it on the left hand side of this guy left side there's a bottom one bottom left click it alright so you have unmuted the thing so this is another way to unmute the microphone the possibility is the battery packs out transmitter packs out of batteries so replace the batteries press this button and slide it down and you reach the double A batteries so you can change that the first one is cable maybe exactly got disconnected so make sure you just check the cables all the cables are attached alright so that's the recording setup and I will go through the backup this is the backup audio so the backup system is usually are you good that you set it up cause there will always be that 1% of the time where things really do go wrong and then you have to fix it and post literally okay so this guy is the motor pod that we have to unlock it so just twist left twist to the left whichever one of the ways then you can extend it twist it back the other way it locks into place that's the motor pod and the camera connects to the motor pod and this camera will be placed usually I will put it at the back of the room and then zoom it cause this is a normal camera handy cam you can zoom quite far in and usually when I use this I will focus just on the screen the reason being if anything goes wrong with the screen capture or whatever I can just use this to kind of like rebuild to just use this to kind of recover the video that was lost or if there were problems with the audio recording I can use this as a backup audio as well so I can take the audio from this guy and then splice it into this video so there have been times in the past where I use this as a last resort there's also situations sometimes where we have no recording somehow for whatever reason our system just crashed so dramatically that there's no way it can recover but this guy is super reliable and we'll use this including the screen capture and all that stuff use this for I'll just use this and upload it and that usually works so you have a hacker space this is usually roughly around there but so turn it on it's very easy just open it it will automatically turn on just open the shutter the shutter on the left hand side zoom out so usually again as I said I'll just use this and point it at the screen if anything happens I'll just use this to recover the screen capture and then the audio and record this press button record and when you're done just press it again to stop recording and this one can SD card so usually before we start I'll also format the SD card so click on this to drop down format make sure I format it format SD card plus SD card is around here alright so with blank freshly formatted SD card you can record up to about 5 hours of footage of this guy 64 gigs so usually what I'll do is I'll put it at the back of the room point it to the right place and just leave it there for the whole meet-up so that's one of those interesting things there's always a camera at the back recording yeah which could be interesting in the future that we need to do something but we don't keep the footage anyway so unless we really have to so if things do crash and we need to use this back up usually I'll step in and get the video and I'll do the post production this is usually the backup that we set up and we leave it there I'll stay on the cover before we let you guys do hands-on with our converters so we have a couple of converters that we use for different situations so for presenters we only have a Mac or something we have USB-C to HDMI converter so that's one next thing we have is a mini display port mostly for surface pros and the older MacBook Pros and some Tinkpads are still using this so you really need a display port to HDMI so this is the second one in very very much older Tinkpads and Dell you have a full display port to HDMI converter so I think these are quite rare nowadays but you can still find them and another one is the VGA to HDMI converter so this is the situation where you get a presenter who has a very old laptop that only has VGA so you use it to connect it to the VGA and then there's a HDMI out from there but for this one you need to be powered so you need to plug this into a USB port on the presenter's laptop it will probably have one spare port so you plug it to VGA plug it to the USB port there and you should power this guy and be able to send a video signal to that so these are the main converters we have there are some obscure there are some laptops with very obscure connectors or very rare connectors like micro HDMI or mini HDMI we don't have converters for that so they are on their own we don't see the proliferation of those things yet but if we do see a lot of that we will consider getting converters from those but they are not very common the last thing we have is HDMI to VGA converter this is for venues where they only have a VGA projector I think in some places like when we were at PyCon this year Republic Poly only has VGA so we had to use our converters on their side they actually have their own converters there so basically for venues where they only have a VGA connector we use this and we connect this part to our splitter so our splitter the one that connects to the presenter also to the projector we will basically use this and connect to the splitter to the VGA connector so these are all the converters that we have and all our sets have one set of these so don't lose any of them all of them are labeled so you shouldn't lose any of them so this will cover 90% of all the presenters the pop that we use we have seen so far through our new tabs are we okay? okay cool, so next thing I will do is I will tie this down and then I will split it into two teams and then you all will try to set up the thing okay tie down and set up usually when we are tied down I want to put back things into the same place where I found them so that I wouldn't lose anything for this guy I think one thing I should note the power is actually to the USB the USB which means it's high inside here so that's the hidden compartment okay cool, I will now do the tie down and you can shut down the computer can I close the whole thing? can you please? just close it we we are not operating a Windows machine usually I just yellow Windows update no let it run it needs to run this course okay so if you do bring the laptop home the day before maybe you could update the windows first first when it's in storage no one uses it so it's a bit hard yeah this is a very long HDMI cable here so this long HDMI cable is for the news where your setup is a bit further away from the like for example you do this at google so google Singapore in their main area there's this big conference room area they are auditorium not basically not the good space, the auditorium area usually we can only put our laptop on the floor and nowhere near the restroom so we use this and extend it on the way to the restroom yeah so that's the thing to do okay let's go down and set our shutdown and cool down okay any questions so far? are we okay? I'll go clear this is not getting oh it takes about a lot of is that light there it's red so usually the cables are put in this slot HDMI cables we have a front so the HDMI's will access converters and stuff we'll just put it at the front there's also spare batteries here for the spare batteries here is for the transmitter this is used by you later on for the when we do our hands on you don't need to set up a backup camera just set up the main thing kind of if you want to try and set up also can just what we thought today is the option of overwhelming is there a lot of things so one thing to note about the recording so once you have recording in the laptop you could if the venue has decent wifi you can start uploading as you're packing up so that's another option you can try but if the venue doesn't have good wifi then you have to copy out the file and then do the upload later on another option you can do is as you're returning it to hackerspace you can just take it out there's another way you can do it so this guy actually has Velcro please elastic velcro thing they kind of like keep this guy in place otherwise you have to carry it on your hand while you're returning on moving around so you just look it through cool, will you timing me how many minutes is that thing I'm kidding okay cool are we good you want to take a breakfast before we start hands on or you want to go straight hands on cool, hand awesome how do you want to organize the two teams C1, 2, 3, 4, 5, 6, 7 4 we will be helping one of your teams one of you will be on that side of the table you can use the brown table and the rest you can be on this side so this one I'll keep it here for you guys, set date so all our sets have a number allocated to them I'll show you the schedule the number is based on when they were bought or accumulated okay so you set 6 so you can set up on this table let's try and if you have these tables again should be fine okay you can do it so you have set 6 okay you have set 8 so 4 of you over there okay and then the 4 of you okay I have no idea but you want to buy it it's about 200 plus dollars yes 200 plus dollars 200 what's the number is that backup you two are doing some power yeah that's all for this that's all for this that's all for this that's all for this that's all for this for this that's all for this that's all for this the receiver sorry this one is for the wine this one should be for the this one this one is for one one for this one oh yeah I think it's oh yeah this is the one this is for the this is for this is for the converter this one is for the this one is for the that one can we scale up the source this one this one this one this one this one this one is real blue first one has blue this one is for the source yes This one is green. This one don't have socks. This one is missing bro. It should only be inside here. One of the connectable. This one is blue. Don't have sticker. This one is powered by the USB. This one is powered by the cable. This one should be inside here. This one is for the receiver. Still have something else right. Microphone, there you go. We can pretend that we have something. The camera is also back up for sure. We should always set it back up at the back. But after we are done with this. Does it feel light? Same channel. I think this one needs to be powered. It should be powered by the USB. This one is connected to the other one. This one is connected to the other one. Hello. This is not my speaking voice. This one is connected to the other one. This one is connected to the other one. Hello. Maybe it's the sauce inside. Why is it muted? Everything is muted. I think now it's in already. The screen is not showing up. We have to be in the app to pretend that we have something. I am just trying to see where that works. Can you try a different cable? It's a long one. It should be actually. Does the screen flash over there? I think it's connected to the other one. The power is on. Maybe the cable is working. Check it around. Use this for the sauce. You are plugging it to the output. Same mistake. Use this instead. Can you play it? Okay. Are you sure? Give it and be active. All of this of course. Start up, shut down. It's strange. Modern laptops don't need to go through the power cycle. It's the laptop screen. It's on. Every time you shut down, windows stop there. It's fine. It's fine. This one is better. Try this. It's a lot smaller than the other one. Change. Use this. Use this for the presenter. Connect to the... The TV media. It's on. It's on. It's on. It's too much. We don't have a sauce. It's on. Your camera is up. I'll try and... Actually, that one was too small. Can you? I can probably get that one. You have to pass the microphone. It's on. We'll try with me first. We'll try with you guys later. I'm the presenter. I'm presenting a very nice keynote. I'll bring up my keynote right now. You can see the awesome presenter. I'll talk a little bit about HR retrospectives. What retrospectives are. Why do we do retrospectives. I'll go around to the right. Left. Right. Cool. Thank you very much. I'm done. Awesome. Thank you so much. Other team will now hijack. Can you see this? Oh, yes. I'll give it to you. I'll change the size. No, it changes already. Keynote. Keynote is so interesting. So, I'm a presenter. I'll talk about this keynote. I'm called retrospectives. I'll be talking a little bit about prime. The retrospective prime directive. Actually, the camera and the tripod can extend a bit more. You can... You can lock it in place. There's around the neck area. You can turn this. Yeah. Right, so... Yeah, so if I'm walking... Yeah. Yeah. So it's okay to loosen a bit so that you can... It's easier to turn. Okay, cool. Cool. Awesome. Okay. Try to tear down. Okay. Okay. Recordation technology. Okay. Is this it? Is it good? It's fine. Sorry. Sorry. Huh? Well, that's all for you. I would recommend you do. What is for this one? Okay. Just use this. Okay, guys, one quick note to... Yeah, what are you all called? Cables. Cables are not ropes. These are not ropes. Do not handle them roughly, right? Inside each of these cables, there are a bunch of wires that go through. And then you probably want to... They have a certain tendency to turn in a certain way. But if you twist it too much, they may end up breaking or degrading the thing. So usually for keeping cables, there's a sort of a twisting action in my fingers to kind of make them go into the way that we... When I turn it, I usually have a twisting action to make sure that the cables are kind of turning into the loop. So it's not so... So for a USB cable like this, it's actually okay, but for audio cables, we don't really have much audio cables here, so it doesn't need to be that particular. But here, at least, you still try to do a bit of a turning of your fingers like this, so that it will basically roll into the loop. So we put the webcam into the pouch so that it's a cushion pouch so that it's a bit more of protection. Yeah. That's a good condition. Yeah. Wow. So many cuts. Cool. All right. So thank you all Michael. So thanks for watching the live stream. So for the next part, I'll be going through with them the details of how to lock in to stuff and all that, which while we're reviewing some credentials, I can't tell you that. So hope you guys can come for the live training so that we can tell you a bit more. Right. Bye. Thank you.
