How can I use the ffmpeg overlay feature to superimpose one video on top of another?
To superimpose one video on top of another using the ffmpeg overlay feature, you can use the "overlay" filter in ffmpeg. This filter allows you to specify the position and size of the overlay video on top of the base video. You can use the following command in ffmpeg to achieve this:
ffmpeg -i basevideo.mp4 -i overlayvideo.mp4 -filtercomplex "0:v1:v overlay x10: y10: enable'between(t,0,20)'" output.mp4
In this command, "basevideo.mp4" is the video on which you want to overlay another video, and "overlayvideo.mp4" is the video you want to overlay. The "overlay" filter superimposes the overlay video on top of the base video at the specified position (x10, y10) for a duration of 20 seconds. The output will be saved as "output.mp4".
