Thanks for the tip on OpenColorIO Simon. I have it installed now and am giving it a go. Have you found the Alexa LogC profile in there pretty much the same as the one on the Alexa site?

Have a look at OpenColorIO (http://fnordware.blogspot.se/2012/05/opencolorio-for-after-effects.html) if you need to convert footage between different color-spaces. It will perfectly round-trip Alexa LogC for example.

Best regards,

you could also make that adjustment layer a guide layer so that it never accidentally renders

I normally put the Alexa LUT on an adjustment layer and do all my VFX under that. That way I know what I'm adding is going to look balanced with the shot when the look is applied. Before rendering I turn off the adjustment layer and render to ProRes 4444. The colorist here is using resolve so he can grade the shot from the same point that every other shot starts at. All of my work should travel correctly with it. I often deliver mattes to the colorist as well to allow them greater control over grading the VFX. I always keep the AE file in 16bits as a minimum and often work in 32bit linear.
