Let’s get those renders out faster with some tips to speed up the renders out of After Effects.
1) Increase your RAM allowance
This may seem like a small change but it will make a massive difference in allowing After Effects to consume more RAM while rendering. To change this setting (in After Effects CC) go to:
2) Reduce the amount of Pre-comps or PRE-RENDER them
You might have just finished making an amazing composition containing a lot of other pre-comps only to find when you go to render the final results the eta may take over 5 hours. There’s a simple fix either remove some pre-comps which you may be unable to do as you need them for your overall comp. So this is when you need to pre-render them.
It may be necessary to export the pre-render using a PNG Alpha Codec – so the background will remain transparent in the layers.
3) Trim Layers in Compositions
This ones pretty simple, a way to reduce your render times is to trim your layers to when they are actually being seen. For example if you have a 3D scene and the camera pans across the scene and then you still have layers active – cut them. These layers need to be stored in memory somewhere and you are just clogging up the system keeping them there.
