  Mpeg 2 Compressing

  Posted by Felipe Madureira on November 8, 2006 at 9:32 pm

  hi, people

  I’ve received a solicitation to made a Mpeg2 encoding, this file should be used to burn a dvd.
  I’d used the MPG2 PAL 7 mbit template from compression master to do this.
  But today the guys told me that this files didn’t work to do the dvd and ask me to use this settings:

  MPG2
  image size: 720×576
  high quality
  format: progress
  bit rate: 1150 (or more)
  aspect ratio: 4:3
  gop size: 12
  audio: 48 khz stereo
  bit rate: 224 kbps stereo

  I’ve tried to do this in the compressor, but the files isn’t open in the QT player, and the compressor don’t let that I set the audio options.

  I really didn’t understand what’s going on

  could anyone help me?

  Thanx for attention

  Felipe

  Well, 1150kbps is very very low for an MPEG-2 bit rate at full frame size. Some DVD players will not play an encode below 2200kbps, so be aware of that. But in order to play the file back in QT, the system you are attempting to play the file back on must have the QT MPEG-2 decoder installed. Final Cut Studio includes this, but the standard QT or QT Pro does not. As far as the audio, that shouldn’t be a problem if you encode to MP2 or AC-3.
