• Connect multiple video with different quality using ffmpeg

  11 février 2020, par park joh

  I have a series of 100 short videos, each one of them is encoding using h.265 but with a different quality level (CRF).
  I want to concatenation all of the 100 mp4 files to a single file but without re-encoding, so each part will save its own encoding parameters (they all at the same resolution, just different quality).

  I want to use this option : https://ffmpeg.org/ffmpeg-formats.html#concat-1 of FFmpeg and wonder if it’s going to work smoothly.
