    9 juillet 2016, par parik dhakan

  • Ffmpeg sidechaincompress with different input audio lengths

    29 janvier 2023, par user19313832

    There are two input files :

    


      

    • First entry is a video with music - 6 min.

      • 


    • Second entry - voice - 3 min.
Here compr will contain the audio of video that is muted when start talking (second input).

      • 


    


    ffmpeg -y -i %pathToVideo% -i %pathToAudio% -filter_complex ^ ^"[0:a][1:a]sidechaincompress=threshold=0.015:ratio=19:level_sc=1:release=1400:attack=1[compr]^" ^ -c:v copy -map 0:v -map [compr]:a %out%

    


    Problem - sound of the video is completely turned off when the voice ends, at the 3rd minute.

    


    This works well for the first 3 minutes.
Then the sound of the video is turned off.

    


    Half of the video remains without sound.
It is necessary that the sound of the video remains, and not turned off.
It looks like it only works on audios of the same length, but here the audios are different lengths ???????????

    


    It is necessary that the sound of the video does not turn off after the 3rd minute. Because the voice file is only 3 minutes.
