  How to remove duplicated frames with audio for a specific section(range of video) ?

  Posted by Steve An on October 20, 2018 at 7:55 am

  is this possible to be removed duplicated frames in section of video from 00:00:00;00 ~ 00:00:00;25 ?
  some video have in this ranges three duplicated frames , some video have 9duplicated frames , some video have 19duplicated frames and so on , so i have tried like this .

  ffmpeg -i in.MTS -filter_complex “[0]split=2[a][b];[a]trim=end_frame=26,mpdecimate[a];[b]trim=start_frame=26,setpts=PTS-STARTPTS[b];[a][b]concat=n=2:v=1:a=0” -vsync vfr out.MTS

  but in this case because audio is not removed so video duplicated frame just changed to black frames not removed . and problems is how to set audio duration as much as duplicated frames ( durations ) for removing ?

  i just want to remove duplicated frames with audio from video 1sec start(beginning) section . not video all
  who can help me ?

  thanks
