DG FastTrack with Final Cut Pro – Possible?
Hi all,
I’ve searched and searched through these forms and found questions similar but never this exact one.
Is there any way to get an MPEG-2 Program Stream with these settings for a DG FastTrack gig using only Final Cut Pro 7 and Compressor 3.5?
Video: 18MB/s
MPEG-2 Program Stream
4:2:2
9 frame GOP
29.97fps
4*3 Aspect Ratio (If captioned the file needs to be
720*486), 720*480 (recommended)
Interlaced lower Field first
Audio: MPEG-1 Layer 2
2 Channels
48KHz
20bit
384Kbps (recommended)Acceptable video and audio quality:
Average digital audio levels must range between –17dBfs
and –20dBfs (Analog: 0dB @ +4dBm ref).
Digital audio levels should peak between –10dBfs and
–12dBfs (Analog: no higher than +3), with a maximum of
three peaks per second.
Setup level should equal 7.5 IRE.
Luminance levels should not exceed 100 IRE.
Chroma levels should not exceed 120 IRE.
If I have to, I’ll spring for Episode. But even then, I have only found correct settings for a file with 720×512 aspect ratio, and not a 720×480 aspect ratio.
Thanks,
DavidAny help would be much much much appreciated

No with FC/Compressor.
The only 4.2.2 MPEG-2 you can make with FCS are IMX and XDCAM.
However, are you sure that they want “422”?
I think that the required data rate is too low for 422/Short GOPs (9 frames).
If was 420, yes you can do it.

Yes I am positive they want 4.2.2

Hi David,
I’m afraid you will need something like Episode or so.
You may ask in the Compression Techniques Forum.

I use Episode with no problems… and our Dallas DG office requires an additional 16 lines of VBI in addition and that’s supported in Episode. They do indeed require 4:2:2.
If you have to, you can edit a preset to fit your needs, rename it and save for futures. There should be a “Program Streams” file inside of the Mpeg-2 preset folder.
