Input #0, mpegvideo, from 'c:\tmpdir\work.m2v':
Duration: N/A, bitrate: N/A
Stream #0:0: Video: mpeg2video (4:2:2), yuv422p(tv, bt709), 1920x1080
[SAR 1:1 DAR 16:9], max. 50000 kb/s, 25 fps, 25 tbr, 1200k tbn, 50 tbc
[mpeg2video @ 02528b40] Warning min_rate > 0 but min_rate != max_rate
isn't recommended!
[mpeg2video @ 02528b40] bitrate tolerance too small for bitrate
Output #0, mpeg2video, to 'c:\tmpdir\xdcam.m2v':
Stream #0:0: Video: mpeg2video, yuv422p, 1920x1080 [SAR 1:1 DAR 16:9],
q=2-31, 150000 kb/s,
90k tbn, 25 tbc
Stream mapping:
Stream #0:0 -> #0:0 (mpeg2video -> mpeg2video)
Error while opening encoder for output stream #0:0 - maybe incorrect
parameters such as bit_rate, rate, width or height
