Conversion of screen captures
Record Linux screen using gtk-recordmydesktop → .ogv file.
To simply convert to Mac-readable format:
ffmpeg -i capture.ogv -sameq capture.mov
Sometimes it is easiest to capture the whole desktop and crop during conversion:
ffmpeg -i capture.ogv -cropbottom 304 -aspect 16:9 -sameq capture.mov
Skip ahead 20 second and convert 30 seconds:
ffmpeg -i capture.ogv -ss 20 -t 30 -cropbottom 304 -aspect 16:9 -sameq capture.mov
Transcoding AVCHD MTS files on Linux
Convert Canon AVCHD (MTS) file to something that can be processed by kdenlive:
ffmpeg -i XYZ.MTS -sameq -s hd480 -ab 256k xyz.mov
Assumes libav* installed from Medibuntu. By default, ffmpeg will use MPEG-4 codec for the MOV container.
Initially, I used "-acodec copy" but VLC could not play the sound in the output file. Therefore, I let it transcode the audio as wekk but keep the bitrate high.
