Help identifing compression specs
on Mar 20, 2008 at 8:29:13 pm


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 720x480 MPEG2 Transport Stream file at about 4 Mbps, CBR.

File Format: MPEG 2 Transport Stream
Video Format: NTSC
Video Size: 720x480
Video Bit Rate: 4 Mbps
Audio Bit Rate: 192-256 kbps
GOP Size: 9
GOP Structure: IBBP

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,

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.

Please post back saying what solved your problem. It could help others, and saying 'thanks' is free!
