To overlay one video on top of another using the ffmpeg command, you can use the "overlay" filter. Specify the main video as the base and the overlay video as the overlay, then set the position and size of the overlay. Use the following command:

ffmpeg -i mainvideo.mp4 -i overlayvideo.mp4 -filtercomplex "0:v1:v overlay10:10:enable'between(t,0,20)'" output.mp4

This command will overlay the overlay video on the main video starting at 10:10 position for the first 20 seconds.
