  • How can I cut segments of audio/video while keeping the other track intact in ffmpeg ?

    8 novembre 2022, par limejellodragon

    I am a newer user to ffmpeg, but I have a slightly complicated use case for it. I need to be able to cut multiple sections out of a video and/or multiple sections out of the audio, with the actual length of the video and audio files remaining intact (e.g. the audio would cut out but the video continues, or the video continues but the audio cuts out). I have been slowly learning about complex filtergraphs, but a little help would be VERY much appreciated.

    


    this is currently my super basic "test script" to see if I can get it to work (in it's actual use case, the timestamps will be variables in a python program)

    


        ffmpeg -i bdt.mkv -filter_complex 
    [0:v]trim=start=10.0:end=15.0,setpts=PTS-STARTPTS[0v];
    [0:a]atrim=start=10.0:end=15.0,asetpts=PTS-STARTPTS[0a];
    [0:v]trim=start=65.0:end=70.0,setpts=PTS-STARTPTS[1v];
    [0:a]atrim=start=65.0:end=70.0,asetpts=PTS-STARTPTS[1a];[0v][0a][1v]
    [1a]concat=n=2:v=1:a=1[outv][outa] -map [outv] -map [outa] out.mp4

    I am a newer user to ffmpeg, but I have a slightly complicated use case for it. I need to be able to cut multiple sections out of a video and/or multiple sections out of the audio, with the actual length of the video remaining intact, like a video editor (e.g. the audio would cut out but the video continues, or the video continues but the audio cuts out). I have been slowly learning about complex filtergraphs, but a little help would be VERY much appreciated.

  • Change the audio of the video based on start and end time

    4 avril 2022, par Vuqar Samed

    Lets say I have sample video named "samplevideo" and sample audio named "sampleaudio". I want to replace the audio of the samplevideo with the sampleaudio starting from 5 sec to 12 sec. Until 5 sec mark the video audio won't change, then sampleaudio starts and lasts for 7 sec.

    


    I tried to come up with ffmpeg command that solves this problem :

    


    ffmpeg -i samplevideo.mp4  -i sampleaudio.aac -ss 20 -map 0:v  -map 1:a -c:v copy output.mp4


    


    Problem :
    
It cuts video starting from 20 sec time mark. What I want is to persist the video and the original audio stream until it hits desired time mark and then use sampleaudio until desired end time.

    


    I would appreciate any help.
