Optimizing Performance for Premiere & After Effects
Posted on February 1, 2011 in Digital Effects, Editing | 5 Comments
Todd Kopriva from Adobe hosted a one-hour session about optimizing for performance of both Adobe Premiere Pro and After Effects. In case you missed it, here’s the recording. They also posted a set of links for more information about all of the things that Todd covered. See this post for those details.

I have 4GB RAM
1.5 of that RAM reserved for other applications
2.5 RAM available for After Effects
For the multiprocessing I have the following shown when enabled:
Installed CPUs (processor cores): 4
CPUs reserved for other applications: 0
RAM allocation per background CPU: 0.75GB
Actual CPUs that will be used: 2
The video above shows the following for their multiprocessing settings.
Installed CPUs (processor cores): 8
CPUs reserved for other applications: 2
RAM allocation per background CPU: 1GB
Actual CPUs that will be used: 6
The multiprocessing settings for ‘Render Multiple Frames Simultaneously’ is unchecked by default (as stated in this video). My question is to get the best performance should I check this to enable it for the best performance? I’m afraid to adjust the numbers and I’m assuming they’re set to the recommended capacity that my system can handle.
I’ve had problems with my computer rendering out AE files to the point where it may have been the reason my video card stopped working in the past. I don’t know if I was pushing my computer to render something its unable to handle or if it was a coincidence.
I’m going to look up the improve performance FAQ on adobes site but I’d appreciate your thoughts/feedback, thanks!
Multiframe Processing is unchecked by default. But given your amount of RAM, I may consider leaving it unchecked.
Here’s what happens when you render something in AE with Multiframe Processing turned on – the computer actually loads up another instance of AE running in the brackground. So there’s actually a second (third, fourth… and so on) copy of AE running WITH your project file loaded. This takes some time to start up, but once it starts humming it does improve your render times.
BUT…
If you only have 4GB of RAM installed, you’re going to run out of RAM VERY quickly. Looking at your specs with .75GB per CPU, you’re only running 2 processes. And .75GB is not a lot if your dealing with a fairly complex AE file.
So long story short. Probably best to leave multi-frame processing off until you get more RAM. But feel free to play with it and see if you see any improved performance (You may still)
Thanks for replying! I’ll give it a try and see if I notice any improved performance. My main concern was burning out my video card again. (still not sure if it was a coincidence that the hardware stopped working or if I was rendering something too great for my system to handle — thank god for apple care!)
Hey,
I don’t know if I can ask this here. But I have a problem with my preferences in AE CS5. I have 8GB RAM and AE doesn’t recognize or uses them. It says: Actually Using 0,21GB and Maximum Using 0,40GB. When I check the Multiframe processing and want to see a life preview it says: not enough RAM, multiprocessing is off.
what can I do?
This was really an attention-grabbing subject, I am very fortunate to be able to find this from bing.
