Premiere dynamic link to AE coming back with RGB colors
I’ve got a Premiere Pro CS5 project that needs some color correction. Most of it I’ve done inside Premiere Pro, but a couple of shots needed to go into After Effects. Using the Dynamic Link, I sent the clips into AE, corrected them, and everything seemed fine back in Premiere world.
However, when I tried to export the the sequence, anything corrected in AE was rendered out much more contrasty — looking all the world like something using the full RGB color space, instead of the YUV video world color space.
So my question is: what gives? Inside the Premiere Pro timeline, everything is fine, but exporting outside of premiere gives me a non-usable movie where some clips are in RGB space and others are in YUV space. Is there some way I can force premiere to export as one or the other? Or better yet, get AE to not convert color space, or get Premiere to re-convert/unconvert the colorspace?

In After Effects, Under your media bin it should say “8bpc” or something similar, click on that and tell us what you have for the 6 color settings.
Off the top of my head, because it is too contrasty, I think it’s a gamma shift rather than a colorspace issue.
What codec/container are your source files and your export?

My first guess was gamma as well. Without screenshots it’s difficult to tell. Heck, even with screenshots it can be difficult….
AE only works in RGB, so your YUV footage must be converted to do any work in AE. This is a major drawback to PPro–>AE–>PPro color correction, in my opinion, especially if you’re working 4:2:2 instead of 4:4:4 (which most of us are).

In AE my project settings>color settings are:
16 bpc (I had tried earlier 32, with no difference)
Working space: none
Match Legacy After Effects QuickTime Gamma Adjustments.The source files loaded into premiere are Canon 7D h264 movs.
I tried exporting my premiere sequence as h264 for vimeo, as animation codec quicktime movs, and as some sort of avi, and all exports were the same — stuff which had gone into AE via dynamic link was more contrasty and stuff that not gone into AE was not.
It MAY be the case that maybe PP is not using the LUT in LUT Buddy at the time of export, which would explain, also the lack of contrast. Because in my project window, the clips that have or haven’t gone to AE actually look the same, it’s just on export where something is bizarro. I’m going to test this theory…

Yeah, it’s freakin’ LUT Buddy. I just used a totally zany LUT I had created for another project, exported the clip with the LUT applied in PP to the queue and then rendered it. The render did not have the LUT applied.
Okay, so that’s the solution there — it’s not a matter of RGB versus YUV at all, it’s a matter of certain effects just not carrying over into the render. When the LUT is applied in AE, it DOES carry over.
I luckily found this awesome RGB curves preset that is damn close to the cineStyle LUT here, so I may just apply THAT in PP and bypass the use of LUT Buddy entirely. Then at least I won’t have to bring EVERYTHING into AE. Although, to be fair, I found that Colorista Free’s interface was far more responsive in AE than in PP. Go figure, maybe everything should go into AE anyway…
Thanks
