I have a 10 second clip --1920x1080 --on which I've created a rotobrush with a refined edge on the hair. I froze the mask after completing it which took forever. I didn't clock it, but it was easily over an hour.
Now I'm rendering this clip with some overlayed graphics and a simple shine effect on the background layer, and the render has taken over 2 hours.
I'm running After Effects CC on a Quad-Core MacPro with 10GB of ram. Something doesn't seem right about all this render time to me.
Anyone have any thoughts?
Could be normal. My usual workflow is to render rotobrush immediately to a DI codec (digital intermediate) and then proceeded from there. No way of telling what is going on without knowing all of the details of your comp. I think you'll find that Rotobrush, Warp Stabilizer, and 3D camera tracker all use up a bunch of system resources and it's best to pre-render before things get to complicated.
Thanks Rick... yes, I think the pre-render makes a lot of sense.
