Initializing background processes with each ram preview normal?
This is an issue that has been annoying me for awhile with CS6. Every time I ram preview, I get the “initializing background processes” message in the info window and have to wait for 15 seconds or so for the preview to start. I don’t want to disable multiprocessing as its really speeding up my previews once they get going, but the slow to start is becoming a pain. My memory of older versions of AE was that it did the initialization once on the first preview, then after that ram previews were much faster to start. This doesn’t seem to be the case for me anymore. If I have made any changes, it also autosaves my project which adds another few seconds to the preview. I’m on an 8 core mac pro with 20 GB of memory. I am devoting 3GB per background CPU with “actual CPUs to be used” = 3. Is this behavior normal? Do I have something slightly wrong with my installation? Is there something I can do (besides disabling multiprocessing) to speed this up?
Thanks,
-Matt

When I experience long delays in the activation of multiprocessor rendering, I have found no solution other then to cancel the render and turn off multiprocessing.

I am working with a complicated comp, but even with no changes to any comp, ram previewing again will cause it to go through its initialization routine again. Its annoying because if you stop a preview to talk, then try to play it again, it has to initialize again (assuming you have multiprocessing turned on). This has seemed to be the case for awhile now, but I know it didn’t used to be. I wanted to know if other people were experiencing it.

where are you saving the project to? Is it local? On big projects I saw that time being long as it needs to save and load your project on other processes.
What I usually do when I want to preview just a couple of frames is to use space bar…let it build up, then ram preview. Though not using multiprocessing, I don’t have to wait 15s to preview 10 frames that take 10s to render.

I have the same issue, and have noticed that it ALWAYS saves first–a bit of a problem when my large files take 15 sec. to save. THEN, it slowly initializes bkgnd processes for another 15 sec. In most cases when I’m working, I’ll just leave it off. It’s enough of a pain for others that someone wrote a script for it. Check out AEscripts Throttle N Purge toolbar. This at least puts the MP toggle on screen, which can be less annoying than having to fetch it out of your prefs every time. Kinda big on screen, with some other features I don’t need, but a bit helpful. It’d be better if he made a smaller “lite” version that has only the MP toggle and such.

I mean CMD-OPT-; + the Multiprocessor screen. Or even better, how about a MP on/off keystroke shortcut like CMD-OPT-;-M or something. Any coders want to take that one on?

Hi Greg,
Thanks for the suggestion of Throttle and Purge. I’d used that script several versions of AE ago, then forgot about it. Its not the best solution, but it does help.
Thanks,
