I have an MPEG2 file with the following characteristics: 704x480, 6929 kbps, 29.97 fps, VBR. I need to convert this file to CBR, while retaining the quality.

What is the proper way to do this using ffmpegX? I have searched the forums and the Internet for this solution and have not been successful in finding it... Lots of similar questions but really no answers.

TIA

Alex
