huge render times
I have a huge green screen project that I am working on. I finished it up and set it to render and was shocked!!! The first codec I tried to use it said it was going to take 72 Hours to render!!! (Standard HD Youtube 720p preset) By rendering a quicktime using the the h264 codec I was able to get my render time down to about 40 hours, which still seems a bit crazy. I’d imagine the more compression it has to do the slower the render will be. Can anyone suggest a faster codec to render too, other than the ones that I have selected?
I do understand, that this is a huge project and I am trowing a lot at my machine. I am using the dynamic link between AE and Premiere. So the footage was keyed in AE using Keylight and those comps are a dynamic link in premiere. Do these times seem normal?

From Dynamic Link performance [link]: “A linked After Effects composition will not support Render Multiple Frames Simultaneously multiprocessing.” To oversimplify a little, you are rendering your key with only one core, leaving the other eleven in your workstation idle.
Rendering from AE and replacing the linked comp in Pr will let you enable multiprocessing and use more of those cores to speed up your render.
Purchasing additional RAM will help you exploint multiprocessing — 12 GB is not enough for Ae with a 12-core workstation. Aim for 32-48 GB.

Amen to what Walter said.
I use DL link between PrP and AE a lot when Im in the tweaking process. But once Im happy with the comp, I render and export a movie (with the project link option checked) from AE. I then Import and replace clip in PrP. With the project link embedded in the movie file, I can always reopen the AE project by selecting “Edit Original” when the clip is highlighted.

I put the rendered comp on V2, and leave the DL’d comp on V1 for the same purposes, Tom.

Jeeze, that’s a pretty nasty limitation of Dynamic link…
