(or encoding raw with 54x size increase). I have more success with ffmpeg, e.g. $ ffmpeg -i A.mp4 -vf "transpose=1" -r 30 -sameq -acodec copy B.mp4 Is _almost_ ideal, apart from x1.5 increase in size... playing with fps does not change it too. -- View this message in context: http://freebsd.1045724.n5.nabble.com/I-need-a-simple-cli-tool-to-rotate-mp4-video-tp5756670p5756683.html Sent from the freebsd-questions mailing list archive at Nabble.com.
