I have two video one is
lyrics.m4v which contains lyrics video with black background and other video with random pics. I want to remove first video black background and play on top of other video.
I am using FFmpeg command:
ffmpeg.exe -i main.m4v \ -vf 'movie=lyrics.m4v [f];[in][f] overlay=0:0 [out]' \ out.m4v
but it gives me this error message:
[NULL @ 000001c5c4369000] Unable to find a suitable output format for '[f];[in][f]'[f];[in][f]: Invalid argument
I am new to FFmpeg kindly help.
