  Variable bit rate (VBR) output with constant bit rate (CBR) settings?

  Hi,

  I am trying to transcode a SD clip via compressor. Here’s the settings that I would like to achieve.

  Video Frame Rate
  25 fps
  Video Standard
  PAL
  Video Codec
  MPEG-2 Video, Main Profile/Main Level
  Audio Codec
  MPEG-2 Audio Layer II or
  Available audio codec
  Container Format
  Mpeg-2 Transport Stream (mpg)
  Video bit rate
  8,000 Kbps, CBR
  Audio Bit rate
  384 Kbps
  Aspect Ratio
  16:9
  Audio Sample Rate
  48KHz
  Resolution
  1024×576
  Scan type
  Progressive

  However, the only problem I have is transcoding the clip to CBR mode. Even though I have chosen the ‘one-pass CBR mode’ in Compressor, the output is still VBR mode. Is there any way for Compressor to follow the settings and achieve the CBR mode? Thanks in advance.
  Mac OS X (10.6.8)
