FCP 7 out put for Grass Valley Turbo
on May 7, 2013 at 12:02:44 am

I need to figure out the best spec for outputting for a Grass Valley Turbo (original not 'GVT2').
My original file is 1920x1080 HD 24fps.

They have asked for Quicktime. They are not sure which codec will work.
I read a post, maybe here, that animation codec will work.
I will also be making a DVD for a backup.

The file is 16:9 but the screen is 4:3. pixel to pixel the screen is
630x480.

I've been having a look to the manual (http://www.grassvalley.com/docs/Manuals/iddr/turbo/071-8401-01.pdf), and although states that imports QT files, it doesn't mention which codecs supports. but being a device with a few years already in the market, is very possible that can't manage the last QT supported codecs (H264, Prores,..).
In the page 21, the manual says that the device internally records MPEG-2/LGOP (4/8/12/15Mbps).
In the page 98, it says that imports MPEG-2 Program Stream/MPEG Layer2 Audio.

Personally, better than a QT Animation, I would try the MPEG-2 Program Stream option.
You can do it in Compressor.

That's not standard size for DVDs.
720x480 NTSC pixels, is the size.

Is nothing about displaying.
640x480 is OK for web videos but not for DVDs.
There is only one NTSC-DVD compliant size: 720x480.
You can make a 640x480 MPEG-2, but DVD authoring applications will reject it.

I'd talk to the person who needs the file: it might be that this GV NLE can read any number of QT codecs.

QT's PNG codec 1) is lossless 2) is 10-bit 3) is capable of supporting alpha channels, and 4) generally has smaller files sizes than Animation, so it's a winner in my book.

While you have the person on the phone, ask how they'd like their SD video delivered: letterboxed, or with the sides of your 16x9 image cut off to fit it into a 4x3 picture from top to bottom.
