SLOW RENDERING - I have tried eveything
on Jul 25, 2011 at 11:56:22 am

I got a brand new pc - i7 quad-core (hyper threading to 8 core)
12 gb DDR3 RAM, 2 TB 7200 RPM, and a 40 GB Intel SSD. Also I have Nvidia GTS 450

I am running Win7 64-bit

I have installed AE multiple times, I have tried playing with the settings (allocating RAM 8 to Adobe 4 to other applications)
I am currently trying to export an all HD video 1.5 min. with 1.5 GB per core, 2 cores saved for other apps. Im using h.264.

as well, I did the shift+preferences to get the secret tab which allows a couple of interesting rendering tools.

All in all its till taking well over an hour for this seemingly simple render.

Any other suggestions?

For H264 renders, it's best to use AME. AME provides for 2Pass VBR rendering while AE only allows for single pass VBR.

With your setup, I would have preferred a setup with 3 cores to AE and 1 to Other Apps. Leave 3 GBs of RAM to Other Apps and have 3GB of RAM per core for AE.

Are you applying any effects to the layer(s)?

Yeah there are tons of effects.
its effect heavy. Should I assume that it will take a couple of hours then?

Probably. You should also know that not all effects take the same time to render. The Remove
Grain effect renders very slowly, for example, while the Levels effect is very fast-rendering.

Sure -- long render times can be perfectly normal for effects-heavy comps.

However, effects-heavy comps can also be RAM-intensive comps, so you may want to watch the Resource Monitor (Win+R, then run "resmon") to see if you're constrained by the CPU or by RAM.

Also, there is no one "right" set of multiprocessing settings in a resource-constrained system. Different comps will have different RAM requirements, and thus benefit from different multiprocessing settings. Getting that right can be an art in and of itself.

There are lots of resources for improving performance here:
