• ffmpeg - different video and audio length synchronization

  4 mai 2020, par Halil Han Badem

  I have a task where the sound is longer and the image should come later.
Actually, this is exactly what I want, but it's a bit different : ffmpeg : mix audio and video of different length

  



  First of all, I leave the picture I draw below to be understood.
Click to see the image.

  



  By doing this I am thinking of catching sync. With which ffmpeg command can I do this ?
Thank you.

  I have one video with 1 hr time.

  


  i want to chunk in different part by specified range.

  


  ex :

  


  

  1. 0 to 10 min

  


  2. 10 to 40 min

  


  3. 40 to 60 min

  ffmpeg -i input.mp4 -c copy -f segment -segment_times 0,600,2400 output%d.mp4
