Bitrate prloblem with ffmpegX

[koepcke]

Every time I create a (C)VCD ffmpeg does not create it with the correct bitrate.I calculate a bitrate so that the movie will fit on a CD but the resulting file is much smaler. F.e. 50 min as CVD on 700mb CD calculates a vidio-bitrate about 1987 kbit/s.Thats OK. But the resulting mpeg-file is only 550mb with bad quality.The same happens to VCD, SVCD.
Where is my mistake???

I've found that that seems to be the case with CVD. You could just do the trial and error thing an bump up the bit rate to see what looks the best and fits.

Although, your problem may be that your profile under the Options tab may be set to Standard SVCD rather than XSVCD. If it is set to standard SVCD, then it won't matter how high (or low) the bit rate is set, it will just stick with the standard 2500.

The same problem happens to me when re-encoding a m2v file. The bitrate that i choose is different from that of the resuting file.

When using the mpeg-2 engine, the bitrate won't increase past a given limit if you don't also lower the q value (ie. if you don't ask for more quality, the quantizer doesn't need more bandwidth).
