Changin Bit Rate on an Apple Pro Res HQ Export? Possible?
on Dec 7, 2010 at 5:48:15 pm

Hi all,

I got a deliverable request from a client in Argentina that has me scratching my head. They want Quicktime with the following specs.

Container: .mov
Codec: Apple ProRes 422 (HQ)
Raster: 1920x1080px
Pixel Aspect : Square
Colors: Millions
FPS: Source
Field Order: Lower
Data Rate: 60Mbps

Using Quicktime Conversion out of FCP7 or Compressor, I don't see an option to change the bit rate. It's grayed out. I assume because ProRes HQ codec requires a certain automatic bit rate.

Is it possible for me to make a file to their specs?

If so, how?

Thanks in advance

Nope.

The bit rate is hard wired into the codec.

Also 1080i HD is UPPER Field first.

I noticed that about the lower field request. Interesting thing about that, my source file has field dominance at none, and I was able to change it to lower in the sequence without "seeing" any change. But the whole thing seems screwy nonetheless.

So, 1 vote for not possible...
