• FFMPEG overlay video over image using movie filter resulting video with no sound

  22 février 2021, par Herahadi An

  I want to overlay srinked video on the top of single image.
I use movie filter to do that. like this

  


  ffmpeg.exe -loop 1 -i Coronavirus00000000.jpg -vf "movie=C\\:/\Users/\Toshiba/\Pictures/\test vcp/\shopi pro.mp4,scale=1180:-1[inner];[in][inner]overlay=70:70:shortest=1[out]" -y out.mp4


  


  It's work. but the problem, the audio from video is removed. The final video out.mp4 has no sound, even though the original video has.

  


  I have read answer on this threat FFMPEG overlaying video with image removes audio

  


  That recommend to Change into ...[padded]overlay=0:0" -y ... Or add -map 0:a

  


  But I don't understand how to implement that answer into movie filter
