Hello Logic.TV peps! I am a Flame assist/compositor at the mill at the Moment. I am working on a Blue screen job and some phone screen comps within each shot. All my batch works well until I bring in my screen asset. This asset becomes jagged and sharp on all the edges and imagery inside. Also, my …

Hello @KevinD Welcome to the forums. This problem happens to artwork if you convert to ACES using an inverse tone mapping. The automated ColourMgt function ViewTransform is great for getting graded rec.709 footage into HDR colour spaces like ACES but it is a little bit of a hack. SDR into HDR will…

ACES Is designed to take any image that was photographed from a known camera and undo all the silly stuff that camera manufacturers do. Rec709 isn’t an image that was photographed from a known camera. It’s already been messed with. So, ACES has two separate but imperfect solutions to convert Rec7…

Hey @KevinD here’s the short answer: have them grade the shot without the screen comp. once you get the graded rec 709 plate back do your screen comp as normal. Bob’s your uncle. here’s the long answer: as some have pointed out ACES was designed with photographic content in mind, not graphic de…

Gonna just relink to what I posted about this before, hope it helps. [image] Converting Artwork to Aces CG for comping Flame Questions This is a a known issue with ACES. The whole system is built around using scene-referred values with plausible reflectance values. So ima…

Hey Randy I meant “shot” as in it looks terrible. Poor choice of words on my part. It seems like any color conversion I do in ACES it still blows my whites out or I need to color grade screen asset as all of you have mentioned. I tried a few ACES luts (ACEScc, ACEScct, & ACEScg). I had the best res…

It’s been a while since I last watched it, but I think @andy_dill suggests a solution to this somewhere in his video here .
