 We have having seen four instructors here, so fifth one. So we have Dr. Yogan Drapal with us today. So he has done his PhD from education technology at IIT Bombay and he graduated I think last year. He is also currently working in IIT Bombay in this IIT Bombay X project and what he will be talking about is in the morning we have looked at how we planned the LED, how we planned the LPD and so on. So now he will tell us some tools, quick tools that you can use to actually create your LEDs. So many of you might find this very good activity as a post-lunch session because you will be learning about tools and you can go back and try them out. Okay, over to Yogan. Thank you sir. So till now you have learned how to write a script, how to create activities and everything but now I am going to show you how you can actually create the video. So those who are beginners I strongly recommend them either to use screencasts or tabletop video what I called it. It is recorded with the document camera. So basically tabletop video is when you write something on a paper and you record that with a camera. I named that tabletop video. So you can create a tabletop video by using this kind of device although I do not use this kind of expensive device. I have created my own versions of these devices. So let's talk about the screencasting. So previously means one year back if I had to talk about how to create a screencasting or tabletop videos I have to describe two different processes but now so the software is available and this software is known as OBS studio open broadcasting software and it is available at OBSproject.com. Here is the website and you as you can see that this is named as open broadcaster software. So basically it is meant for broadcasting yourself rather than to create screencasts or to record tabletop videos but it is configurable and it is extremely useful if you want to create any kind of educational video. So today I am going to demonstrate how to use this and it is very easy. So here I have OBS studio and it has a very simple interface. So when first I will talk about how to record screencasts. So it has this scene box you can see scenes. So you can create multiple scenes but let's not complex the software then in each scene you can have multiple sources. So you can see this source box here because I want to create a screencast. In order to create a screencast I want to record my display. So I have to add a source that can record my computer screen. So here when you click on plus sign you will see there are many sources and that is the beauty of the software. So here one is say display capture that means you can capture any display that is connected to your system and currently there are two displays attached to my laptop. So when I will add this display capture you can also give it a name. So let's give it a name screen and say ok. So you will see this. So what it is showing it is showing the screen my screen. So my screen has OBS ok and because it is recording that it is seen recursively. So at present it has only display 0. So if you have multiple monitors or multiple source attached to your laptop then you will see multiple display. So it also allow me to make my laptop as a control machine by not recording it but using it to control all the activities and recording some other display. So let's record this one and it also give you opportunity to capture the cursor in the video or not. So I am saying that I want to capture the cursor and I will say ok. On this black screen you will see the exact output that you will get after recording. So you can now see what you are recording. This facility is not available in many other proprietary softwares also. So when you have decided what do you want to record it is simple to record by simply saying that you want to record something. So there is a button that says start recording click on that and recording is started. So this button is now says stop recording correct. Let me minimize this. Now it is recording all the activities whatever I am doing. So at present I am at OBS studio website. Now I will move to Tech Smith website. Let's move to Amazon, Learn by Watch, my Gmail, some YouTube channel. So there is enough activity I have done on the screen. Now I want to stop the recording correct. So I will click on stop recording and that's all. I have created my first screen cast. So if I have converted my system as a control means I want to display what is being recorded and recording some other display then I can actually see what is being recorded. So let's see where is the recording. You have to go to file, click on show recordings and your recording will be here on the folder. Yeah it's here and you can also see it is also recording the cursor correct. So this is how you will record your first screen cast with this software. This is a open source software. You can use it without any problem means you do not need to buy license and other things. Yes. So this was the basic use of this software. So here is what I did. I recorded the screen correct and as you can see while I am recording the screen I am seeing this recursive screen. I don't want to do that. Sometimes I know what I want to record. For example I want to record the this explorer chrome screen. When I know what I want to record then I do not need to select the display capture instead what I need to do I will first remove that source. I will add a new source and I will say that I want to record the window capture rather than display capture I want to record a window. And good thing is that you can't you can select multiple windows on a single recording. This facility is also not available in many proprietary softwares. So let's say I will record a chrome screen. So it is optional to write a name and now I have all the whatever windows are open on my system that is played here I can select any one of them. So I select the chrome. I want to capture the cursor or not it's up to me I want to capture the cursor. So I am selecting this and say okay that's all. Now you don't see the recursive screen what you see you see the window chrome window that I want to record it and similarly I will open some other software. So I will open this everything. It's a software and without minimizing that what I will do I will record one more screen. So I will say window capture again because I want to record that too. And now I will select another window that says everything this is a software and say okay. Now I want to resize either one of them or both of them it's up to you how you want to use this. So it saves a lot of editing time. You can put the content exactly where you want to put them after the during the production time but here you can put them before even before you start recording correct. So let me make it like this and this one like this and now I will go to this everything window and what I will do rather than resizing it there I will resize it here. I will arrange it as per my requirement got it. Now I can start recording and that's all. Now whatever activity I will do even without minimizing that because it's not recording this particular OBS Studio screen now. So I can search anything here basically I'm doing some activity here similarly I can do some activity on this window and everything is being recorded and when I'm happy with my output I will say stop recording and recording is now available at a particular place okay it's here. So I am recording two separate windows you can record multiple windows without minimizing one and opening other correct. This is what we generally do those who have created screencasts they know when they want to work show how to work on two different windows or two different softwares in a same video then they have to minimize one open other this work is not required correct. Let's now see one more advanced use of OBS Studio. So what I want to do most of the teacher wants to do that I want to record my screen as well as my face on the video correct. As I already told you that there are sources and you can add multiple sources. So let's add one more source and see what's the possibility here. So there's a possibility to add video capture device. Most of the laptops now have a default camera and you can buy another camera I recommend you what you should buy. So let me select the video capture device and say okay now it's recording my face because it's using the default camera. So at present I have only one camera if I would have multiple cameras attached to my system then I could have recorded all of them together. You can configure the quality of the video and let's I am selecting a default values and say okay. Now I can resize it and place it anywhere on the screen. So I believe now you get now you get the idea correct. So this is how you can set your screen and when you say start recording you are recording this without any editing software without any post-production and anything else correct. Let's stop it and see how it looks okay. So those who have done recording they know how much time it take even if you have recorded everything and edited everything then you put that video into rendering and it takes a lot of time depends on the size and the complexity of the video correct. But here I am able to create this complex structure without any production cost. So there are several other options in the input source. So let's see you can also add external audio input capture. So if you want to record the sound from other mics then you can also add that. Similarly browser source if you know exactly you want to show the Wikipedia screen then you can click on this browser source and type the address there and it will show the Wikipedia screen inside the software itself means here only on the screen. Color source if you want to add some background color for example I don't want to show this black color then I can add a color source and choose a different color and put that somewhere on the screen. You know display capture game capture is not useful for you. Image if you want to show a particular image for example a logo or something else then you can select that and display here. Media sources it's not useful when you are recording it's useful only when you are streaming yourself. Text when you want to show some text like your website URL and some important URLs on the screen. So I think that's all if you want to record a screencast okay. Let's now talk about creating a tabletop video. For example if you are writing on a paper and you want to record that how will you do that with the help of this software yes sir please. Is there anything available after the production of the video? Any editing is available. Yes I'll talk about that. Yes it is possible yes yeah so what you have to do you have to click on this plus sign and you have to say audio input capture that's that's for the external mic for example like this mic it is connected to a mixer that is then connected to the system and then you want to use that but you want to use some other mic they're like the Roode Lavalier mics zoom H1 mics there are several mics if you want to use them then you have to connect the mics here and in that case those mics will be available here. So at present it my system has only one mic so it is showing only one mic if it has a camera attached to that it will show the mic of the camera also and if you have another mic then it will show that mic also in that case you can configure anything and the mic settings are available here file settings and audio so here you will see all the mics that are attached to your system so at present it has only this internal microsoft mic microphone nothing else. So here's my suggestion for you if you want to record either yourself or yes sir. Is there any time limit for recording the video? No no no it's open source software I record means I stream myself every day on YouTube and Facebook and it goes for one hour to one and a half hour and there is no time limit for that. So I will suggest you to buy this camera Logitech C920 it is very popular and very useful so it can record 1080 pixel quality means full HD video and it costs only 10,000 rupees I believe yeah it's only 10,000 rupees and now it's one sale so less than 10,000 this is Logitech C920 so instead of seeing this quality you will see a better quality and it is very useful if you want to record some other sources means it's I can't move that camera correct but you can move that you can put it somewhere else and record yourself when you are interviewing some person you can attach two cameras to your system and point each camera to different person and this is how you record interview video in low cost and for the audio quality I will suggest you to buy this one zoom H1 so it it records in the memory card and it also gives you output to your devices like laptop so you can directly record your audio with this device and again you can put it somewhere else it's not attached to your system so you can put it anywhere and then capture the audio so when you want to record the tablet of videos let me show you an example of tablet of video so this is a tablet of video basically an operational amplifier is an active element so you can see teacher is writing and we are recording that with the camera so although we have used different camera but now this camera is available so we can improve the production quality in the less amount means it's only 9000 or 10,000 rupees camera so what you have to do you have to connect this select the source now you know how to select the video capture correct then you have to arrange that camera somewhere on top of your paper and record this that's all so here you can see we have wasted half of the screen can anyone tell me why we have done that no no no the actually problem problem is that screen size is 16 by 9 the ratio of the screen is 16 by 9 but we have only a4 size paper available with us correct so we can't do that so what I did in the second version I improved that so I really so now you can see that the whole screen is covered with the paper only I have done that of xt or how will you be presented by the xf so a4 is already land escape winner recording a4 recording in land escape mode correct no if I'll increase it will stretch it's not stretched correct paper size but no moving the camera will not work anyhow large career but the paper size is fixed how will change the paper size no video in video editing if it would have possible I would have done that in my first video no then I have to upload it in 16 by 9 currently you are viewing it at in 16 by 9 yes you're correct so let's not waste the time what I did I went to the paper mart by the whole a size paper and cut it into 16 inch by 9 inch and this is how we are using that yes yes correct yes absolutely but there is some yes you can use that but there are some problems with the mobile camera what I have seen when you record with the mobile camera audio is generally not synchronized with the video then you must have a good mobile which company am I then it's good I don't I have done the same with the my camera it didn't work out but it's good if it works out in your case yes any other question okay so let's move to other part that's the editing portion so sometimes editing is not required so currently what we did is we put all the elements in the skin and if teacher knows what to teach and he has planned then editing is not required so 20% of our videos do not require any editing but for the 80% videos we require editing and for that we use open shot video editor it's a linear video editor if you have used any video editor then you can easily use that the good thing about this is that it uses blender's library so this means that if you have any model 3d model built in blender then you can directly import that and use it here let me show you the open shot video editor it will take some time I will show you the quality of zoom h1 that's written on the learn by watch is my youtube channel it has a 20% of videos that we create so we create a whole bunch of videos and we put some of our videos here on our channel so that if you can see the quality and they can decide whether they want to go ahead with the purchasing and all so let me show you the audio of audio quality of zoom h1 so this is the quality that you will get with the zoom h1 mic and some voice modulation so let's now talk about the open shot video editor it's very easy to use this is the screen and there are some tracks the idea is that whatever clip will be on top that will be visible correct so you have to import some videos let me import the video that we have just recorded when you want to edit it drag it to one of the track and you can zoom it from here you can't edit it unless you see the audio is where is the audio that helps you to decide okay by using this you can see the web form so the web form is actually displaying your audio so when you are recording sometimes you stop you pause then you start again and you don't want to give that that video to your students so you have to edit the video so here you have this facility in the software that you can see the web forms this help you to recognize where you did not spoke at all and then you will go there for example if i want to remove this portion from here to here what i have to do i'll have to go to the starting point then i'll say slice right click on that particular portion and say slice and i'll say keep both sides right i can let her decide whether to remove one or not but let's say that i want to keep both side and slice it down now i have two videos okay again i'll click on display and show web form now i'll go to another point and i'll again slice it select the portion delete it and bring it here to the starting point this is how you do the editing in this software so generally for the beginners i'll suggest only to remove the unwanted portion don't do anything else okay so this portion i call it cleaning cleaning the video so the unwanted portion or the where teacher has gone wrong you have to remove this with this technique and once you are done you will export the video export video it will show you some of the formats so mp4 is the most popular one although you can select any one of these and you have to click on export video i'm not click on that because it will take a lot of time so this is how you'll do recording and editing so let us say when you have this okay let me tell you everything so you have to use OBS project or OBS software to record the videos does not really matter whether you want to record a tabletop video or screencasts if you are using the camera make sure that you are using exactly this camera logitech c290 because it removes many things means if you will record with the external camera like this then you will have two clips one is your screencasts portion and a video that will come separately then you have to process that and arranged it somewhere in the editing software and then you have to do lot of things okay so if you don't want to waste your time in that bring it then if you want to record the audio this is the audio device that you should use there are many other devices but they are costly so I don't recommend them so if you want to if you have buzzer you can go with the road mic for the editing I use open shot you can also do the same so let us say that with these softwares and with these techniques you have the video okay now you want to deliver it how will you give it to your student many teacher uses whatsapp correct but you can't track whether they have watched it or not even if they have watched it how much portion have they watched it if they are faking it or not you don't know correct so what I do I use a software basically I LMS that is known as WP LMS so you do not need to write it WP LMS because you have to buy it it's not open source you can use Moodle if you want to go with the free versions otherwise you can simply use the wordpress not the WP LMS correct all the features that I am going to tell you are also available in wordpress if you know how to work on that so this is learned by watch website and this is how WP LMS looks so I put most of my videos on Vimeo not on YouTube okay Vimeo you know about Vimeo I put most of my videos on Vimeo then I arrange them here so most of our videos are available on Vimeo and then I bring them here on WP LMS wordpress basically and on wordpress I use this special plugin let me show you that this is the important part so the plugin is made by h5p.org some of you have heard about it if you are not using it start using it it will help you so h5p plugin is available for Moodle wordpress and Drupal so if you are using Moodle you can use the h5p plugin it allows you to embed the activities inside the videos let me show you one of the example let me show you the interactive video so the video can be hosted on Vimeo or YouTube it works with the both services once the video is there the plugin allows you to bring the video in your system and add some elements to it so here we will see some examples as you can see it is available for wordpress Moodle and Drupal and it's very easy if you know how to work on MS word you can work with this plugin and it is also showing that in a video inside a video what activities you can embed inside a video you can embed a multiple choice question with one or more correct answers fill in the blank question drag and drop question interactive summaries single choice question mark the word activities drop and drag images tables labels text and links I think this is sufficient for most of our work right it also allows you to jump to a particular time so whenever one of this activity will come you can decide whether to whether to pause the video or not so it will pause the video and if a student will give wrong answer you can set the timeline on the video where to jump the studio so if he has given the correct answer you might jump him to the next topic rather than giving the explanation on why it was wrong and all should I play it see as you can see when it is playing the video we can see one activity here when you click on it will show you some text and it's optional it's not pausing the video the video is playing will show and it will disappear after sometime a student can also decide the playback rate of the video which is not available in default embedded youtube or vimeo videos and whenever there is activity you can see the sign these are small symbols can you see it this this blue one similarly a multiple choice question is here video is not paused by default so teacher has decided not to pause the video but a student can still attempt it by clicking on it so when they will click on it this will appear in a beautiful way and they can select what's that similarly it has many activities so this highlight the ingredients that have been added so far we have to select the words so strawberry is milk so this is how they get the feedback and you can also decide to add one more button whether to bring them back to watch that particular portion or not so because of the slow is internet speed I am not able to show you this to you but you can see it so this is the fill in the blanks activity this is how they will get feedback this is a drag and drop quiz so this animation is not visible but I think you get the idea correct there are some tips and finally you can give them this I like this summary so what's the correct sequence of doing something so a student has to do this so they immediately get the feedback and this is what you get with the h5p this facility is not available in many proprietary services and even if it is available it's not available in the beautiful way either the quest quiz come below the video or it comes very poorly with the text and bad graphics but here it is very good comes with the animation gives immediate feedback and it also records the activities that you can directly import to any tin can supported lms so that's all from my side if you have any question please ask that I wanted to show you but somehow it is not working so I can't show it right now but it's very easy it's very easy if you can work with the ms word you can work with that also videos videos are available either on youtube or vimeo okay then when you install this plugin you have to create one h5p when you say that and you go to this you for example you like this example this is interactive video so what you do you download this there's a option to download it when you download it and you have to upload it on your system once it is uploaded that this category is available in on your system means you can create interactive videos now once it is available on your system so it gives you very beautiful editor allow you to put multiple choice question in between allow you to check whether to continue or pause I guess so if you want to see some of the videos means on how h5p and all works I have a youtube channel known as et mantra you can go to the channel and I keep uploading videos there and if you do not find any video there just send me an email so this is a et mantra channel and you find lots of videos on how to embed technology in classroom or online education and all you can also write down my email address and whatsapp number and you can send your queries to me I will be happy to answer your queries okay so while you are taking down yogre and rapals details let me just give you one minute on his phd topic so he worked with me on teaching programming to hindi medium learners so if any of you have learners who are hindi marathi whatever vernacular and you want ideas on what you should put into your videos to ensure that your learners are able to not just comprehend but also to learn the english language he that's another topic on which he is a good person to consult with thanks yogi thank you very much okay so in spite of these software gans that yogi gave let me ask yogi a simple question how much time will still a person take to create a 10 minute video right from planning so how much time do you take so you have he has around 3200 videos till now so let's say a five minute educational video related to a computer let's say you are teaching recursion to a student now to teach recursion to the student right from planning till production let's say a five minute video how much time will you take so if i know my subject so i take one i take six hours to record one hour video that's my time okay that includes editing and production time also so but a few teachers who come to me to make videos for a five or ten minutes video from planning to production they take whole day and they do not edit the videos they sit with my team and the team edit the videos so for five or ten minutes video even if you know the topic for first or two first or for first five videos you need almost whole day to from planning to production and okay so with an expert like yogi saying that you need all he needs almost one is to six now imagine you start creating your own videos for a course
