  Help identifing compression specs

  Posted by Lars Bunch on March 20, 2008 at 8:29 pm

  Hi,

  I have a client asking me to make compressions from betacam tapes to the following specs. My attempts to make these compressions have resulted in no audio.

  I am wondering if these specs might be related to ADVC compressions.

  NTSC 720×480 MPEG2 Transport Stream file at about 4 Mbps, CBR.

  File Format: MPEG 2 Transport Stream
  Video Format: NTSC
  Video Size: 720×480
  Video Bit Rate: 4 Mbps
  Audio Bit Rate: 192-256 kbps
  GOP Size: 9
  GOP Structure: IBBP
  CBR (NOT VBR)

  GOP Settings: M Frames (3)
  GOP Settings: N Frames (9)
  Do not close GOP
  Audio Frequency @ 16 bit / 48 kHz

  Audio type: MPEG 1 Layer 2

  I am working in FCP Studio 2 but can’t seem to get anything to encode to these specs.

  If you recognized the above and can tell me what software to use to get this compression on OS-X, I would really appreciate knowing what it is.

  Thanks for any help you can provide,

  Lars

  If you have Final Cut Studio 2 then you should also have an application called compressor which should have no problem creating MPEG-2 to those specs.
