I will try the animation codec later, but I doubt that will help. Episode Pro isn’t really any help to me either since i tcan’t deal with PSD or TIFF image sequence quicktimes. If I try to encode my Blackmagic 10bit or 8bit files with Episode Pro I get an equal bad gamma shift.
Playing some more with compressor I found out that if I apply a gamma value of 1.2 in the filter settings that I get a resulting image very similar to the input. Of course I am afraid that it might look to dark when played back with anything else but the quicktime player. If I play that vide with Firefefox for example it is too dark.
As I mentioned before the same problem seems to be affecting some of the trailers on the apple website. Here some screenshots:
Here is a screenshot from the Perfume playing in Quicktime:

Here is that same shot playing in Firefox:

The Eragon Trailer, however, looks fine fine in Quicktime:

But is too dark in firefox:

Do you have any idea what’s going on here?
