 Welcome to this video tech talk on making a video tech talk. I had some questions about how I'd put it together So I just explain the process I went through. I basically prepared for a regular tech talk here screen record on this And then had this software to switch between a couple of things So most of it is the same as you do for a regular tech talk There's just this extra step of doing the recording So I'm going to go over the software I used to do the recording to re-encode the video and then upload it to Confluence in the end That's this start off by showing you around the software I've got So if I switch now into this OBS software, you should be able to see the software itself from the outside This is OBS Open broadcast a software studio or something and here We've got a scene where you can see a little video of me in the corner Sometimes I quite like to see the presenter when they're talking you get an idea that someone's here and Then you get a screen capture because that's what I've got set up here So I'm going to move now to show you the OBS studio website She now be seeing a copy of my Chrome that's open. This is the OBS studio Open broadcast a software studio stuff if we scroll down you can see they offer downloads for Windows Mac and Linux It's free It's used by a bunch of things because you can put together quite complicated Setups and recordings and create professional products and all sorts of other things that I'm here I'm being quite careful as I'm scrolling through because the way I did the encoding if I do lots of quick Movements, it's probably not going to show up very well in the video at the end and That is because I've re-encoded it at a low frame rate to make it suitable for use on our network Nice file size small to do the re-encoding. I used a piece of software called handbrake Which you may have seen before handbrake is for Windows only there are similar things for Linux on the command line FFmpeg does a very similar Re-encoding job if you know the parameters and things, but I'm just talking about the Windows software used here Okay, so if I go back to the software after you do the basic setup You will get this but it will be blank and so we need to add things called sources and scenes Which is this section down the bottom left corner. I'm going to zoom in on that So to set up a scene you click the plus to make a new one add or remove There's various scenes down here as you can guess the title screen text to the title The one was called laptop and cam you now see me and I've added a nice background I thought was roughly the same sonic colors. It's not correct But don't worry about that this display in Tom, which is the one here with me in the corner Hello, so you can see the display so I normally have it set and Here's a zoomed in one called scenes and sources this lets you just see this corner a bit more So I had to set up this bit beforehand in the main talk I only had the display and Tom and the full view of me in there because that's pretty much what you see when we do Tech talk, it's the person presenting the video or it's their screen share. So that's what you need to set up So to set up the display and so display and Tom. I'll just go into here I am created a new scene and then I had to have a new source if you right-click in the source So click the add button you end up in add You get various options as input audio capture because handles the audio sources separately If you've got dozens of mics and all clever stuff at home good for you I don't is just on this headset and there's another built-in one on the microphone Bound here, but these ones are terrible on these so I didn't use them So it's on the headset mic for me at the moment. Hopefully the audio quality is okay for you If I scroll down, we should be able to see Levels popping up and down If we go to add you can add browsers. There's a browser built into it I don't like using that's a bit clunky mostly it works, but if you want it, that's in there The color source so on the beginning you see the nice color on the outside. That's just a color source. You add that Everything ends up as an existing thing you can add and go through and stuff Just added a nice background color for things Images game captures all clever stuff if you're streaming and go on twitch and all that sort of stuff Maybe you use all this stuff before you know way more about it than I do I don't know this image is just background image image slideshow as you'd expect text is how I put the title onto the beginning of this video Just put some text in so you can go in the background color over the top of me or whatever VLC video source any of you who use VLC, you know it can stream out video and apparently you can have Multiple video streams coming from different things coming in so I could have like squares of videos and live streams and webcam footage and security Camphor just who knows why don't Video capture device is something I'm using that's what this webcam comes up as so if we click on this option here We will see that there's a create new option and the option of left right laptop because I've got a thing in here So I'll just go through making a new webcam thing because you'll probably need that We'll call it video capture device for now And then we get a new window up and you go select from the devices I've only got one device the moment is the bill in laptop camera click that Deactivate configure video compressible. You can muck around with these things and things. I don't think I did anything clever with it I just created it. That's how I got laptop Which is the laptop this camera working here once you've made a Scene and because in this scene I've then got the display capture. Oh, I've got two of them That's lovely. Get rid of that one for that breaks thing So now I needed to add the display capture the background So I go into here. There's a window capture and I Don't like doing the window capture because that didn't work so well for me because that that's a bit like in Webex where you share your screen, but you share one application Tracks mostly correctly, but you can get confused display captures nice Especially if you've got two screens You could have this software running on one screen and then have your presentation on the other and unlike me Where you're gonna have layers and layers going on top of each other This is nice to put apart from when you get someone popping in a notification in the corner of your video Turn that off maybe So display capture comes up and you have existing again move it So it's not behind me because I can't remember which of these windows you can see it gets confusing when you're in your section And you get new properties now This is a bit confusing because on a display capture thing you get a preview of the display you're getting but again drop down There's to all the devices you've got I've only got one display at the moment if you had other monitors There'd be other monitors capture the cursor turn that on or off if I turn that off My cursor disappears for you probably right now. If not, it's fine cancel that right These things are all in layers. Let's turn that off there magically pops in there So you can see in the bottom corner There's a layer and there's locks where you can set things in different layers I don't think dragging up and down just I changed the layer So if I turn this on it probably won't be a difference. Yeah, it's in layers So it's behind you can't see what I've turned on or off Because it's in the background of the video. It's hidden by this one And if I turn this off you just get me turn this one on So it gets confusing. It's just layers of stuff if you've mucked around in Word the same stuff So I suggest you put together two scenes of your own I don't know if I can import export them or anything like that, but it's not the hud for you to do I suggest you probably just want a scene that's you and You and what you want to show or Like this or you can leave yourself off completely and just have display It's up to you Um, you probably don't need a title. You probably don't need this unless you want to do an introduction bit or a final closing bit That's why I had this because it makes it a little bit more human And uh, that's it basically for the sources and scenes The only other section that you're interested in in this, um, you might care about the audio levels You can see as I'm talking here a little dancing cursor Usual thing in audio stuff is green is good If I start talking a bit loud it gets yellow, which is not so good And if I scream get really loud it goes into the red not good That's going to muck up the level So it's probably busy trying to tune things on average to keep it at a reasonable level for you and not to The only other thing you need down here is to start stop recording. I In my settings Somewhere setting settings settings Video You can pick the type of video output. There we go. Uh, my recording format is left to mkv Which isn't so easy to view on windows, but it does mean you can pause the recording and there's no warnings here when you change this There's various warnings because it's not the preferred video format for the studio Start recording starts recording the nice thing is I can pause So if you want to do some transitions take a moment to set up some more displays Load a web page or anything you can pause it I won't do that now because you won't see what happens So I can try when you unpause you just magically pop around this so it can be a bit confusing But it's helpful if you want to break and set things up and make sure that you're doing everything and whatever I won't click stop recording because that stops recording you get one hit Recorded the video if you got other software to stitch together videos and stuff great I'm trying to do a tech talk in the tech talk one hit straight through that's the settings in that Studio mode is confusing cutscenes confusing. Don't need it. I'm not going to do it now So at the end of doing all this When you finally get to the end of your tech talk recording and hit stop recording you get a video output settings controllers after that I then need to use another bit of software called handbrake like this Um to re-encode that video for two reasons one I wanted to make it in a format that windows can cope with easily Which is mp4 basically loads of stuff's got support for that And another is I wanted to drop the frame rate right down because when I'm typing into a terminal or showing you static tech You don't need 30 fps or 60 fps frames per second It makes a huge difference to the size of the file and nothing's happening on the screen So there's no reason we have to get above 10 fps You can see me talking here, and it's probably not that judry in this video will be in 10 fps, but I might upload it When you download and install handbrake and I'll go to the handbrake studio thing for a sec Again, just download it. There's more information on how to settle this up All I needed to do for handbrake was set it up. I loaded the pre built-in stuff. There's a 720 30 P in here vmeo youtube should be clean fish broadcasting online And if I'm putting this on confluence it's going online So it needs to be similar settings. I use this as the basic setting and then I had to make sure that that was an mp4, which I think it is the only way dimensions I didn't touch Filters I didn't touch in video. I changed this frame rate to 10 or 12 makes it nice and slow Peak or constant. I don't think that matters too much I think I slid this if you hover over the text you get some help And basically the lower the number the worst quality of the video but the smaller file So I slid this down to 20 that way because that's the lower end of standard definition video And I set the encoder level to slow because it will take a very Well very slow take a very long time for it to encode it But it usually makes a better quality video and smaller video And I check the audio and make sure the bit rate was dropped to 128 because you're only listening to my voice I am not a piece of classical music. You just need to be able to hear me clearly Subtitles there are none chapters there are none. You can set that up if you want to listen And then I saved a new preset just so I wouldn't have to do this every time So I did my preset A description You can add it to categories if you want to make loads of categories they pop up in that menu the dimensions custom Why I left that because it's something what you do have to do seemingly is in the audio Make sure you set this rate to Whatever level you want in here and you can choose whether you want stereo mono It doesn't make a massive difference sound if you don't do that This seems to override the settings that come up later on which is not good Same with the dimensions they override whatever sayings you've got before it will import the dimensions correctly it seems so This 1080 by 720 is probably bigger than the screen. You'll actually view it on you could make it smaller But this works well enough for me should give 15 minutes video So then you need to pick a file that you're going to encode so it gets a bit odd Here so if you do open source drag or drop a file here, so I wonder I'll go into my file menu and pick a video And I'll grab the one I did earlier Which is if I could do a nice short one drum routine Oh, no, I did the one I did it looks like a confusing So this is the full rate file and you can see in the bottom corner or maybe not It was recorded. It was about 114 megabytes in total for a 14 minute video There is a 100 megabyte limit on the confluence page and it doesn't need to be that size anyway So now I've dropped this in it's loaded it and you can see there's a preview of the video down in this corner You can jump through different sections of it to make sure it is the file you want things Then you need to do a save as Example And I suggest you save it as mp4 because that's the container format that windows has a lot of support for the other Format if you've got vlc you can set it up, but that's the one that normally works Um web optimized is important but it's already set for us because that means it's easy for people to just skip through And you won't have to download the whole file and all that stuff So that all the settings should be saved from before and I will load up my custom preset of What did I make Tom? Well, this is the one I made before so this is saved So I just need to load that each time and won't have to change the settings And then you click start and code if you've got a load of videos to do You can queue which is what I just did and you can change the source or you can change the options And so we can output multiple ones and then queue again I was going to say the same job But then you can see there is a queue in here and you've got the ones from earlier in the day This is the last one we just added so it says this hasn't been done yet And you can delete things off the queue copy them off the queue And then either you start the queue or start the job and when you start the queue It's going to sit there and it's going to encode it will take it a while to do the encoding It's probably not actually going to take it an hour. There we go. It's about 10 minutes On those settings it takes about the same length as it would to record the file But that's it at the end of it you'll get a file out of it and I've done this one earlier So I'll show you the one I made earlier that is this one at 1080p instead of being 140 megabytes And some change this one's 75 megabytes, which is fine That's well under the 100 megabyte limit and the quality of the other video And this one which I'm about to record seemed reasonable for a tech talk So that's it thank you for watching and that's so if you want to make your own video That's roughly how I did it and how to set it up Good luck
