the vimeo hd export preset does that, my movie is an .mp4. and it looks fine, in quick time, but on vimeo and youtube it creates this gamma shift. I will post screen caps of my sequence, my quicktime player, and the vimeo player to show the difference between what’s on my computer and what my upload looks like. Should I detail any of the preset’s info to see if there is a discrepancy? Thank you again for your consideration and support.
