CPU load of different Effects in AE
Hi,
I’ve been searching around different forums looking for an answer, a chart would be even better. I’d love to know which effects load down your comps the most. For instance Fractal Noise vs Turbulent Noise. I know turbulent is a little lighter on your CPU. Maybe this wouldn’t affect one instance, but when you’ve got 30 or more clouds in precomps it can slow you down a bit. Even just a list of really light on the cpu effects would be rad.More specifically I’d love to know:
-Levels vs Curves vs Exposure
-Direction blur vs Radial blur
-Camera Lens blur vs RSMB
-Set Matte Vs Track Matte
-PNG w Alpha vs Separate Alpha luma matte
-TIFF/PNG/JPG/Prores efficiency
EtcAny help would be appreciated!

after effects is good but i think adobe maybe not telling us something , i think after effects is bad written application.
i have used other apps video editing and on the fly u add affects blue and the scroller does not get slow not for a second super smooth , so its after effects to blame and script writers

Profiling the render time on a project is fiendishly tricky problem: it looks like it should be simpler than it is. Camera Lens Blur is very “computationally expensive” (read: slow to render), but just as an example of how difficult your question is to answer directly, HOW slow it renders depends on the blur radius and iris shape.

Yeah definitely, thanks for the reply!
I know other effects must be a little more quantifiable though, such as curves vs exposure. I’m sure exposure is far more efficient. But as for levels, it’s hard to tell.
I’ve been working with 4-5k outputs for multiple screens on large scale projecting mapping projects. It would be nice to save some cpu cycles!
Maybe I’ll just do some tests of my own, contribute to the community, ya know?
Thanks!
