I have a number of video files (MOV) which I only need to rotate 90° clockwise.
As it may be needed in the future as well, I first tried using ffmpeg and then mencoder command line in a Nautilus script but unfortunately I wasn't satisfied with the reduced quality of output video.
Avidemux GTK has produced the output video in the same quality as the input video. But I would ideally like to use it from command line, i.e. avidemux2_cli, although I couldn't find any info about the use video filters like rotate in the documentation.
