Do you know what constant bit rate means?

The reason I ask is that you do not explain what is wrong with your output files
and that constant bit rate does not mean constant frame size.

Please test current FFmpeg git head - the only version supported here - and
provide the command line you tested together with the complete, uncut
console output if you need support.

fps=29.97 is always wrong and 30fps (as stated above) != 30000/1001 (which
you may have meant with 29.97)
