  ffmpeg.exe -r 10 -loop 1 -i 5197.jpg -i audio5197.wav -c:v libx264 -x264-params keyint=1:scenecut=0 -c:a aac -b:a 32k -pix_fmt yuvj420p -shortest out.mp4

  


  I'm trying to make a video with a picture and 7 hours of wav,There is always a few seconds less audio at the beginning of the video, and the sound becomes smaller.

  


  Thanks for reading and help.

  


• Ffmpeg : Output a video made of several video chunks of the input video

  20 mai 2013, par mad

  I was wondering if it was possible to output a video made of several extracts of the input video.
  For example outputting a video made of the first 10s of each minute of the input.

  I know you can do it programmatically, calling several time ffmpeg with -ss and -t to make the chunks and then merge them, but is it possible to do it in one command using video filters ?

  Thanks !
