  Changin Bit Rate on an Apple Pro Res HQ Export? Possible?

  Posted by Ryan Foregger on December 7, 2010 at 5:48 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…
