For me ffmpeg is a way to avoid re-encoding video while doing useful things (because for one I have a pretty slow PC):

  • split audio off, edit it, then rejoin it
  • combine multiple dashcam clips without re-encoding
  • trim dashcam clips down without having to open a big video editing app (that would probably re-encode)
  • set the orientation flag when it's upside-down, again to avoid re-encoding before uploading to YouTube

One time I downloaded a 1080p movie and the audio was clicky, so I downloaded the 720p resolution version and combined its good audio with the 1080p version's video, no re-encoding.
