Proxy layers render slower than original. Video layers in general are extremely slow.

When I'm exporting a composition, using proxy layers of simple elements, it takes a lot more time than disabling the proxy and having it render 'from scratch'. Or it's barely any faster.

If I'm adding a single video to a new composition to render it out again as a test it's extremely slow.

In this case AE only has to read the videoframe and rerender it without doing anything, and I'm getting 2-3 fps.

Shouldn't proxy layers always render quicker than the original, regardless how sophisticated or simple the composition?

Is there any codec that handles video better/faster in AE?

I'm using prores 422/4444.

It's such a shame, since old versions (pre 2014) handled video much faster.

We have faster computers with slower AE performance.
