After Effects CS4 - Multiprocessing Tweak

After Effects CS4 - Multiprocessing Tweak

This quick tutorial will show you have to enable the multiprocessing tweak for dual/tri/quad core processors, which will balance the workload across your CPU cores to increase frame rendering speed. The only catch is that you are required to dedicate ram to each core to use, thus putting a limit on how many cores/ram to be used at one time.

Also, this is what i got from AE.

The amount of RAM required for each background process varies depending on your system configuration; at least 1 GB per process is recommended. Optimum performance is achieved with computer systems with at least 2 GB of installed RAM per processor core.

Do you have yours set at 1.5? I'mnewto this forgive me

@saeroner

The 1.5 I have it set for is for the rest of my computer to use, I had it set for 500MB (or 0.5gb) of ram per CORE. If you have a Quad Core, 4 x 0.5GB = 2GB usage. You can certainly go higher if you have A) More cores or B) More Ram available!

Hey thanks man, great video. Any idea how this works with 4gb on dual cores? I heard that Multiprocessing on 4gb may slow rendering instead of speed it up, and that to really benefit you need about 6gb... but that was just from some blogger so who knows, right?

Part 1:

If you are on a 64-bit OS (Which I hope you are) Then you will be able to utilize 1.5gb's per core while leaving 1gb for the rest of the computer. Which is a decent trade. Using Multicore Processing will increase you RAM preview rendering speed, allowing you to get higher quality renders at a quicker time, but the trade-off is a slightly lower amount of video rendered (So you'll need to RAM preview portions instead of the whole thing, depending on the length).

Part 2:

And I haven't noted any performance decreases at all. You'll have to link me this blogger in a pm so I can check his statement lol. Thank you for commenting!

@ILegitify me either

[tombotification]

works great, a lot faster :D

[themightyqsprodigy]

I have 8 gb's of ram, it says something about me needing to render more than 1 frame

[adamp8810]

@saeroner I wish i had 12 GB....4 is not enough

[GamePlayUK]

when i render the outcome is really jerky and i get random twitches and color flashes in each frame can someone tell me what the hell this is?

[saeroner]

I notice that under "RAM to use for other applications" you have it set at 1.5

Will this slow down the performance of a NLE if using along with AE... PP.CS4 in my case... I've got 12 gigs
