OBS Studio is the best screen recorder and a great solution if you are facing problem to share online content like, video lectures with your students. It not only record the screen of your monitor but also helps in live streaming. You may have seen some youtuber who remains live on youtube channel and telecast their work.

OBS Studio Introduction as a Screen Recorder

OBS Studio is an open access platform and used broadly for live streaming on social media and on websites. Its so simple and user friendly. You can use it to record your computer screen, like your PPT, any video, or websites in live mode.

Before you use it, this is important that you know some popular mode of video presentations. This will help you to choose the best option for your case. These are;

1. In this mode we just fix the camera on stand or tripod and teacher teach on the white or blackboard. This is similar to like you are teaching in the classroom. But for this mode you will required a good camera along with stand and good light arrangement in the room. Also if one using the white board, check glaring at the corners. So no reflection should be recorded in the video. Sound recording quality should be good. Its easy but little costly setup.
2. Second mode is called the picture into picture mode. In this mode you record your power point presentation and keep your self picture (fix or through webcam) at one corner. To record this type of lectures you need a good quality screen recorder. Some of them are paid and some are free. The free version let you put their logo in your video and there are some more constraint. Like you can record the video upto 10 minutes only. No green screen feature is available in free versions in general. Through OBS Studio its cost just your PPT time, and it is free.
3. Pen tablet or graphics tablet with screen recorder. You may have seen Khan Academy videos where Sal Khan presents content through pen tablet. He use different color of pens on the black screen and write free hands. I am sure you may be interested for such technology. But for it you have to invest some money to buy a reasonablly good pen tablet that will cost you at least 7 thousands and an intermediate software that will use for writting purpose.
4. In this mode you connect your laptop with a big TV screen and an external camera together with webcam record the information. generally this is useful for those who want to teach software languages or programs on their laptop.
5. Ligt board is useful to make video more attractive. In this mode presenter use a high quality transparent glass board and write on that by neon markers of different color. In this mode one who watch the video he/she looks presenter behind the board. Its very interesting but most costly products. For it you require a dark sound proof room, good video recording camera with mic, professional light setup and video editing software.

Out of these 5 techniques I will suggest second option to the beginner. This is almost free provided you have a laptop or your own PC with atleast 2GB RAM. You can also use the notes mkaing app Microsoft One Note that is very helpful for online classess.

In general people use Google classroom but I give preference to the Edmodo that is similar but far better in terms to organize the personal class, quizzes and assignments, etc. For more information one have to visit the Edmodo and its use in online teaching.
