Re: [OT] transcode e clipping
> Ma credo che molto presto riceverai altre domande!
Appunto. Io ho questo filmato:
filmato.avi: RIFF (little-endian) data, AVI, 640 x 304, 25.00 fps, video: DivX 5, audio: MPEG-1 Layer 3 (stereo, 48000 Hz)
Io vorrei togliere le bande nere e avere un aspect ratio di 16:9. Però se ci provo ottengo una strana risoluzione (640x640):
$ transcode -j 4,0,44,0 -C 3 -Z 640x,fast -i filmato.avi -c 0-1500 -x mplayer,null -y xvid,null --export_fps 25 -o prova.avi -w 2000
$ file prova.avi
prova.avi: RIFF (little-endian) data, AVI, 640 x 640, 25.00 fps, video: XviD
Dov' è che sbaglio?
Ecco l' output di transcode:

Un aiutino?
