There are some codecs that are in common use that aren't going to allow for sRGB so they will gamma shift internally. I believe Animation is one of those. (iirc) I always leave that codec and gamma I deliver to the client. There are still people out there with older FCP boxes(not old FCP but OLD OS) that will want 1.8. Randy S.
