I sent a clip to Ae to key out the green and then animate a product shot. To have a nice and clean key I linearized my workspace and set the color space to Rec709 2020 (I don't know which one is closest to Premiere Pro Rec709) but when there is a noticeable gamma shift, it loses a lot of exposure. How can I keep the right gamma/color spaces between the two apps?
I would think the Ae color management setting for working space would be the Rec.709 2.4 gamma, near the top of the options in the Project settings Color tab Working Space dropdown list. That should match with Premiere.
