Render fast, preview slow
on Jul 10, 2018 at 1:21:42 pm

Hello !

I have a issue with my new PC and After Effect. I really don't know why.

I have a project with a very simple shape (a square), moving on my precomp (100x100 px). I put this precomp in an other comp and I dupplicate it a lot (100x). When I pre-render my project, it's very very slow... like if my PC isn't enought powerfull (it still a simple scene for this kind of computer !). But when I did real render, it's very fast (the render takes few seconds when the pre-render takes minutes).

Have you got an idea to fix that ?

My PC :
Intel Core i7-7700HQ CPU 2.80 GHZ
RAM 8GO
NVIDIA GTX 1070

Thanks !

Once something is previewed, Ae caches the results so that subsequent previews and renders are faster. This might be what you're seeing with this example.
