Sister issue being having partial transcoding of a multi video stream file
impossible
Input #0, nut, from 'out.nut':
Metadata:
encoder : Lavf52.102.0
Duration: 00:13:15.00, start: 0.000000, bitrate: 63 kb/s
Stream #0.0: Video: mpeg4, yuv420p, 352x288, 25 tbr, 25 tbn, 25 tbc

Stream #0.2: Video: flv, yuv420p, 35x28, 25 tbr, 25 tbn, 25 tbc
this breaks encoding:
