  Creating HD MPEGs

  Posted by Sanjay Chalisey on March 5, 2008 at 11:25 am

  Hello,

  I’ve been asked to create HD MPEGs based on the following dimensions:

  Pixel Dimensions: 1920 x 1080
  Frame Rate: 25fps
  Bitrate: 36 mbit/s CBR
  Profile: Main
  Level: High
  VBV Buffer Size: 488
  Closed GOPs
  N Value (Number of Frames in GOP): 15
  M Value (Number of Frames Between Anchor Frames): 3
  Sequence Header Interval: Each GOP
  Video Encode PID: 16

  If you look at the settings, Compressor (as far as I know) cannot achieve this. For example, If I choose the MPEG-2 or the HD MPEG presets and then try to adjust these (after duplication), I cannot change the bitrate settings from VBR to CBR as an example.

  Would be grateful if another encoding application can be recommended for the apple mac (does Pixel Tools have a mac version of their MPEG encoding software for example?).

  Many thanks in advance.

  Somehow I could do this…I don’t recall what I did. I think it depends on which preset you start with, duplicate it and then adjust the settings. I had to make a similar MPEG and at first I could not change the VBR setting…..later I tried again and I could select CBR no problem.

  Again it depends on which preset you start with (can’t recall) and how you change the settings.

  I loathe compressor.

  You are probably going to have to invest in another program. I’m sure episode will do this but does episode do hd..? I use Rhozet which is a pc program, you can pretty much make anything m2t’s to flash etc, sound like you need a transport stream because of the pid but there is also a need for a audio program id..
