Rotate Video with FFmpeg
Raw
rotate.md

Values for the transpose parameter:

  • 0 = 90 counter-clockwise and vertical flip (default)
  • 1 = 90 clockwise
  • 2 = 90 counter-clockwise
  • 3 = 90 clockwise and vertical flip

To rotate 180 degrees, use "transpose=2,transpose=2"

Using -codec:a copy will simply copy the audio instead of reencoding it.

ffmpeg -i in.mp4 -vf "transpose=1" -codec:a copy out.mp4

A more complex variation re-encodes both the audio and video but I could only get it to work with the FFmpeg that comes with WinFF 1.4.2. I think some of the options here got deprecated.
