  10 bit Uncompressed rendering in AE

  Hi

  Has anyone come across a problem with rendering in 10bit uncompressed from After effects and the image gets 10-20% brighter?

  You are experiencing a bane of my existence – the apple 10bit gamma shift. It has been an issue for a LONG time now, but there are solutions. What codec are you rendering too, and what hardware are you using?

  Hi, thanks for the response..

  I’m rendering from after effects to apple’s 10bit uncompressed 4:2:2 codec, as this is what I captured the footage in FCP as. I Captured the footage as 1920×1080 50i through a BlackMagic HD Decklink card, Dual SDI, etc..

  Funny thing is, that if I open a uncompressed shot in quicktime and turn on the high quality option in properties.. it gets darker..
  This is a common thing “with quality” on dv I know, but that never became an issue in AE.. This brightness issue is..

  In response to the post before.. The rendered footage in FCP is brighter against the originals… how do I change the YUV RGB.. and will that effect my mastering?
