Thanks Chris. A really informative read. That article was written in 2008 I noticed, yet here we are on the doorstep of 2012, four years later and we are still having these problems. Thats atrocious.
I have been aware of the QT -> FCP gamma shift problem, I asked about it in this list last year. Not tried x264 yet though, I will now. My issue today though is the blacks getting crushed, not fading, on encode to H264 via Telestream Episode. I'll contact them to see if they have any idea about gamma tags being used. All in all highly frustrating for professionals trying to deliver good looking work to their clients after all the hard work, the creative and keyframing, is done.
Anyone done any tests with Adobe Media Converter and the Main Concept codec? I will give that a run for comparison too
cheers for all the advice and discussion

"The most useless day is that in which we do not laugh" -Charles Field I'm having a hell of a time trying to get a render off to my client that resembles to color shown in AE. Workflow is this:
PSDs imported and animated to 16bit comps (the artwork is a concrete texture with a black vignette over, lots of greys, blacks blending into each other) Rendered to 16bit PhotoJPEG .MOVs (the masters look fine, no gamma shift at this stage but at 750MB too large to upload to client) Encoded in Episode to H264 (blacks are crushed, all detail is lost, gamma is generally shifted darker) Encoded in QuickTime to H264 (gamma is shifted lighter and reds are shifted towards blue)
I've tried playing with various options and settings in Episode, but any gamma compensated reverse shift I apply brightens the highlights but the blacks are still crushed. Playing with the QT export filters are really hit or miss with little effect.
Anyone come across this before and found a workaround? Or a better encoder. I had an old version of compressor at one time but removed it as it was so unstable and buggy and required a reinstall every two weeks.
At this stage I've resorted to trying to introduce the reverse gamma shift as an adjustment layer in AE prior to final render to compensate for the shift in Episode. So far I have yet to find the sweet spot that solves the problem
