From (other) encoding GUIs I know that I can specify (for AVC/H.264 encoding) a maximum key frame interval (e.g. max 200).
How do I do this at the ffmpeg command line?
Furthermore I would like to resize the output video to lets say 640*400 pixel.
How do I specify this new resolution at the cmdline for ffmpeg?
