Long After Effect Project Making Computer Slow
on Apr 20, 2017 at 2:39:09 pm

I´m doing an animation 2:30 minutes long. In the begining preview where alright but when I animate more and more it gets slower.

I´m using DUIK very few effects like shatter, bending and glow and the motion blur.

Any tips in how to work in long animations?

Should I render first little shots ratter than the whole thing?

If you prerender elements of your animation, you may be able to speed things by quite a bit. But first, you should define what you mean by "slow". Please tell us. It may be possible that things are fine.

Could it be the poligones in the puppet tool that make it slow to preview and render? Or maybe the vector illustrations? They are quite simple. Even I rasterized some of the more complex ones.

Sorry, but it is still difficult to know. You haven't told us the amount of time you consider to be slow. It could vary from "not instantaneous" to "a week".

If you have comps in your project that you don't expect to work on, prerender them.

https://helpx.adobe.com/after-effects/using/precomposing-nesting-pre-render...

After Effects will render it to your disk and temporarily replace the comp with the rendered file. This will keep AE from needing to render the comp every time you render and take some time off the final render — it's much faster to render one video layer than multiple layers with effects. If you find out later you need to make changes, you can switch back to the original comp easily.


To make AE run faster while you're using it, try this:

- Precomp. It's much faster to work on a comp with 5 layers than with 100.
- Solo. If you can't precomp, solo the layers you're interested in. After Effects will hide and ignore the other layers (and stop calculating their effects) which will speed up previews.
- Turn down preview quality. In the preview panel, set Resolution to Half or Third. Previews will render faster.
