PS: I've tried adjusting the Secret prefs to purge every 60 frames, but that hasn't helped.
I'd appreciate any suggestions.
My initial thought is that 14 minutes doesn't seem like very long to process a 5000-frame HD movie.
Sometimes, a lot of background processes will start up to render with Render Multiple Frames Simultaneously multiprocessing, but then some of them will stop rendering because they don't have enough RAM, etc.
What happens if you leave at least 2GB for other applications and set minimum allocation for each background process to a high value, like 2GB? 3GB? Are you following the recommendations here?
Maybe this is a silly question, but why are you using AE just to rerender? Surely Quicktime Pro or Final Cut would be better for that.
I totally agree, Szalam. But this was a test of AE. I noticed that my actual project with effects and layers 'n junk was getting progressively slower as the render went on. Even the though the effects & number of layers remained fairly consistent (in fact, there were actually fewer effects and layers in the later part of the project, but the estimated time kept growing and growing.)
Todd, yes using 6 CPUs, I have enough memory for 2.27GB/CPU and 2GB left for other apps. I agree 14 minutes isn't bad. But when it screams through the first few hundred frames in seconds and then...starts.... to... chug.... and... get....slow... I get the Spock raised eyebrow expression . And the fact that it stayed at "Est Complete: 14 minutes" for 15 minutes really makes me start pulling my hair out in large clumps.
I was thinking maybe I could break it up into segments? Render 1000 frames in one queue, another 1000, etc. Give it a chance to do clear its mental constipation by doing whatever internal purge it does when finishing one render and starting another? Does AE kinda fart out at really long renders?
You know the inner workings far better than I!
(And how's this gonna work with 64-bit? Each process can have have petabytes!)
Okay this happened again. My 5000 frame project rendered in 3 hours yesterday. Today I turn off a blur in one layer and it then took a whopping 9 hours to render! What gives?
This was with a fresh restart, no other apps running and same memory settings.
