  AE CS5 to Media Composer 4 Gamma Shift

  Posted by Jonah Walker on July 9, 2010 at 3:58 pm

  I actually posted this in the After Effects Forum, but was recommended to post over here. This is the original post: https://forums.creativecow.net/readpost/2/982727

  I am running AE CS5 on Snow Leopard and the Media Composer is on Leopard. The footage is XDCAM, and is exported by avid as a QuickTime same as source. I did the compositing and the footage when re-imported into AVID, the gamma has shifted to be significantly darker than the original footage. I was exporting lossless as Animation Codec.

  The footage looks correct when viewed in QuickTime, but is very dark in AVID. I decided to try other codecs and tried Uncompressed 10 bit, AVID DX HD in RGB and YUV, and AVID 1-1 in RGB and in HD and all had the shift, though the YUV seems to have shifted more than the RGB.

  Could this have something to do with the Gamma Shift from 1.8 to 2.2 in Snow Leopard? Is anyone else seeing this issue? Any help would be greatly appreciated.

  I was recommended to try changing the gamma for Pro Res, but Media Composer 4, does not accept ProRES, only Media Composer 5, should I change the lossless tag to write the gamma flag or the AVID codecs within After Effects, like 1×1 and the DX HD? If so what are the codes so that I can change them within AE?
