• How to use FFMPEG to convert mp4 to gif within a target file size ? [closed]

  8 septembre 2024, par DavidNyan10

  I've seen many ffmpeg questions asking about compressing an mp4 to an mp4 but not to a gif.

  


  I have an input.mp4 (12mb) that I would like to convert to output.gif whose result is 14mb using the normal conversion. I want it to be the best quality (both resolution and frame rate) under 10mb. How can I do that ?

  


  Something like
ffmpeg -i input.mp4 --target-size=10mb output.gif ?

  


  I'm on Windows by the way.

  avformat/hlsenc : correctly compute target duration
  With HLS, the duration of all segments must be lower or equal to the target
  
  duration. Therefore floor(duration + 0.5) yields incorrect results.
  For example, for duration = 1.35, floor(duration + 0.5) yields 1.0, but the
  
  correct result is 2.0.

  avformat/pcm : decrease target audio frame per sec to 10
  This makes the wav and pcm demuxer demux bigger packets, which is more
  
  efficient.
  As a side effect of the bigger packets, audio durations can become less exact
  
  for command lines such as "ffmpeg -i $INPUT -c:a copy -t 1.0 $OUTPUT".
