Most screen recorders enable users to record the computer screen with audio. The sync of the audio and video is really a big problem. For most screen recorders, the video and audio tracks are not separate from each other, cropping a video clip in the timeline also means chopping off your narration along with it. That would not be what you want. Or if your recorded video is all right, but there is something wrong with your narration, you have to restart your narration and screen recording until you got it right.
