  Cineform with maximum depth renders?

  Posted by Dustin Moore on December 3, 2011 at 6:11 pm

  Ok, I’m an expert at using cineform under Vegas but I’m
  looking to switch to Premiere Pro and I’m confused. Can
  someone who understands when Premiere does levels conversions
  straighten me out?

  I installed Cineform after I loaded Premiere CS 5.5.0 x86
  so that all of the plugins would be in place.

  I have a Cineform YUV:4:2:2 High quality file on the
  timeline with regular SMPTE bars that run from 0 to 100 IRE
  as measured in the Premiere Pro waveform monitor.

  If I render to Blueray h264 with the “Render at maximum depth”
  not checked, the resulting m4v file has proper
  levels with 0 to 100 IRE luminance.

  However, if I have “render at maximum depth” checked the
  resultingbm4v file has incorrect levels. The blacks have
  been lifted and the whites crushed as if Premiere has
  applied a 0-255 to 16-235 levels conversion.

  I don’t know why Premiere applied a levels conversion. The
  Cineform file is already YUV with the proper levels. It
  should just ask the cineform plugin for 10 bit YUV padded
  out to 32 bits with no shifting.

  Is there a way to do maximum depth rendering in Premiere with a cineform file and not have the levels destroyed?

  Many thanks,
