With this code I'm trying to add a video with a transparent background over another, more precisely a waveform over another mp4 video.
what is wrong in the code below? I try it on a batch file, but is not executed..
ffmpeg -y -i test.mp4 -i waveform.mp4 -filter_complex [1]format=rgb24,colorkey=black:0.3:0.2,colorchannelmixer=aa=0.3,setpts=PTS+8/TB[1d]; [0][1d]overlay=enable='between(t,8, 13)'[v1]; -map [v1] -map 0:a -c:a copy -c:v libx264 -preset ultrafast export.mp4
thank you for your gelp
