(The oCam screen recording function can support AVI, MP4, MOV, TS, VOB and other audio and video formats, and can also customize the FPS and speed settings of the video. If you want to record for a long time, the file capacity can also support more than 4G.
oCam not only supports full-screen recording and custom range recording, but also can record the sound from the computer or the sound from the microphone at the same time. It also supports dual screens and keyboard shortcuts. I use it more conveniently than OBS.)
