The After Effects Memory and Multiprocessing settings were as follows. This project consisted of three 1080i AVCHD videos with three iterations of Keylight and a two layers with Color Finesse color correction applied. I would still like to follow through on these tests for that 1% though. This is definitely a 1 in 100 project for me and like you said, this won't apply to 99% of users. Should I turn those layers off before running these tests or would that not have an affect on these test?Īs a preface to these tests I would like to reiterate your point that it is extremely rare that someone would have a project like this. I have some temporal effects like Rotobrush in this project. I'm going to rerun some of these tests with this project to see if even this is enough to see a difference in RAM speeds.īefore I run these tests though I do have another question. However, that being said, I have recently finished a project that has 8 iterations of Keylight amongst mamy other effects in a project that has nearly 20 nested comps (maybe 18ish) where the deepest nest is I think 4 layers deep. Now I see that the reason is simply because it is very rare to have a project where even "slow" RAM is the bottleneck due to frequently accessing the hard drive. I've seen many posts where people say, "It doesn't make that much of a difference," but no one explained why. I've searched for a while to get a straight answer on WHY RAM speed didn't matter. Thanks Mylenium, this is exactly what I've been looking for. Nothing personal, but you are obsessing over something that is completely irrelevant for 99% of all users, including highend users. You would have to use an extremely memory hungry effect like Keylight or use extremely deep nesting with about 20 nested comps inside one another to see any delay in passing the buffers (not speaking about actually calculating them), but otherwise you won't see much influence. With your recommendations I will create a new project that will be a better gauge of the affects of RAM speed and add those findings to this thread. So, my question to you all then is this, can you recommend a type of project with effects that will primarily use the RAM without having to access my SSDs? While my tests show a good "real world" example of the effects of RAM speed they do not show the full picture. Even though my SSD is capable of over 500MB/s sustained R/W it's still not even remotely close to how fast any of those RAM speeds were. However, after thinking about this for a bit I realized that this is probably due to the fact that my RAM needs to load data from and dump data to my SSD in this project. So, from my testing I found that RAM stpeed really doesn't play a large role in this situation. 5GB reserved for other programs, 2 CPUs reserved for other programs, 2GB per core. The project consisted of 6 AVCHD videos played simultaneously and some very basic effects like corner pinning and cc wire removal. Water Cooled Intel Core i7-3930K (4.3GHz OC)Ģ56GB Sata III SSD for Project Files and After Effects Disk Cacheġ6GB (4x4GB) Corsair Vengeance RAM (Stock timings are 1600MHz 8,8,8,24) Below are my findings, but first, my system specs. At least not for the type of project I tested it with. In short, my finding are that, no, it doesn't make any difference. Hello, I ran some tests today to see if RAM speed really made any difference when it comes to After Effects.
