This video details the steps for recording a short video clip in Zoom, including hosting a meeting, sharing your screen, recording your screen and locating the resulting video clip.
By default, OBS Studio is set to capture your system default desktop audio device and microphone. You can verify this by looking at the volume meters in the mixer section of the main OBS Studio window, and see if they are active. If they aren't moving, or you suspect the wrong device is being captured, click on Settings -> Audio and select the devices manually.
Next, you'll see that the preview is a black screen. OBS does not capture any video by default. To get started capturing, you need to add a Source. At the bottom of the window is a box called 'Sources'. Click on the + (or right click inside the box) and pick the source you want. As a few examples, select Window for software applications, or Video Capture Device for a webcam or capture card. An easy way to record from a DVD is to play the disc in a media player such as VLC, then use "Display Capture" as your video source.
Double check that all your settings are how you want them in Settings -> Output. Then, just hit Start Recording or Start Streaming. We strongly encourage running a test for a few minutes to make sure that there are no issues, rather than just jumping in to your first stream or recording. If you run into any issues, or need further help, take a peek at their help portal. Once you're satisfied, you can go on to creating great content. That's all there is to it!

Once your recording is done, you can find it using File -> Show Recordings. You can change this in File -> Settings -> Output -> Recording.
File -> Remux Recordings will quickly and easily convert your video files into MP4.
