Hi, i am working on green screen interview shot in UHD 4.2.2 10 bits . My computer has rtx 3080 amd ryzen 9 5900 and 48 GB Ram 2700mhz.

I cut the ITV on premiere and deleted the green screen in AE. the thing is, that the ITV last over 6-7min (at 25fps) i know i should not work with footage that last too much like this on ae BUT the composition has: 1precomp made of 2 layer of background. This precomp has: lumetri color (changed a bit the WB), a bit of chromatic aberation from red giant Universe suite and a lens blur. And my character (shot on green screen) has keylight, spill suppressor, drop shadow, lumetri color. Thats it. There is overall 2 precomp and AE tell me that i need 1hours for rendering but, after 2hours rendering, still saying 1h and even 2h. It render maybe 1min/frame or more. Its horrible. I tried to render precomp separatly, same problem

(I already had gpu acceleration, multi frame rendering activated and allowed AE to use all my ram) So whats wrong with this help pls it's about a week a try to figure out whats wrong

Hey there Amarok_,

I read about your case. That is a pretty long compositing piece. Are there cuts? You could try rendering out individual cuts to see where the problem lies. Sorry for the frustration. I hope another community member might have a better idea.

Thanks,
Kevin

thx for repply,
I tried to render (as test) a small part of itv from the shot without any effect and it render with pretty high speed. i also exported some question (title on screen with multiple layer of typo for stylized typo) in Pro res 4444HQ, took me around 30s - 1 min to render 20s of writing composition on alpha channel. so i think the problem come from the addition of multiple effect because, i try to render question by question the interview but i have the same problem. What i don't understand is that i have a pretty strong PC, so we need NASA Computer to run adobe software ? Right now i am rendering 1800 frame from this project (1 question) i already spend 20 min rendering for 19% of the final rendering.
I am not helping my pc because i continue working on subtitle on this project on premiere pro but once again, i don't have an old and slow pc. (I render faster realistic 3D render from blender than compositing in after efffect xD)

Hey Amarok_,

It seems like you are drilling down and finding the issues. You might try rendering out anything with an alpha and reimport it as a flattened file. That could save you some cycles in processing, perhaps. Try it and let me know.

Thanks,
Kevin
