Macbook Pro 17 hours to render basic video!! How does an 8 core Mac Pro compare to the 12 core?

Hi,

I've been really stressed out that my good old Macbook Pro with 4GB of RAM is no longer adequate for working with After Effects and I desperately need to upgrade. At one point a simple 3 minute video with basic 'CC glass' and 'Sharpen' effects said 174 hours to render!

I understand that the 12 Core Mac Pro would be faster that the 8 Core, but the extra cost would be an issue, I'm in two minds whether to go for the 8 Core and save up for a while longer and get the 12 Core. Can anyone offer any advice?

Also, this is the spec that I added to the basket to work the price out, does this spec look OK to start off with? I know that I can add to and upgrade in the future should I need to like adding more RAM etc., is it possible to upgrade from 8 Cores to 12 Cores?



Thank you in advance :)

More than enough for any high-end needs but later add more RAM and a SAS or extra SSD hard-drive for working files.
Im more curious as to what your rendering to get those numbers?
Do you have the NightFlight test file?
If you can download that, render and post our times.
There could be something wrong with your file or your system.

I would wait a couple of more weeks and see if Apple announces new SandyBridge Xeon bases Mac Pros.

I think that the main source of the problem was that the original Quicktime file that I imported (4GB is size) was used multiple times within the same composition, although I had trimmed down each instance of the file.

I also duplicated the same adjustment layer multiple times (approx 40 or even 50 times), also trimmed to the length I required, with Twitch effects on.

Plus, a few instances of a Lens Blur effects, only short instances with a layer mark and opacity flashes on them.

Plus an overall CC Glass and Sharpen effect, which I turned off for the render.
Which one of these do you think was the main cause?

No I've never heard of NightFlight, what's that? My Google search only gave me results for a nightclub in Moscow :)

Did you know that AE defaults to rendering ALL effects applied, whether they're tuned off or on?

If you want to render only active effects, I'm pretty sure the switch is in Preferences. If not, look in Render Settings or Output Module templates. I'm not in front of my AE machine at the moment.

No I didn't know that, I can't find the setting either?

Hi Dave, can you tell me where this setting is to only render the effects that you've applied please? It would be very useful to know, thanks.

This page on Improving After Effects performance is very useful:

4 gigs is a woefully small amount of memory. You can't use multiprocessing with that tiny amount. Turn it off now, and don't turn it on again until you have a proper amount of memory to take advantage of multiprocessing: 16 gigs is good.

I wouldn't be surprised to learn that if you were using multiprocessing, your poor computer had to disk cache just about everything, which REALLY slows things down.

For a new 8-core machine I'd say 16gig RAM is minimum. For a 12-core I'd say 24gig minimum, but ideally 32 or 48. (32 might be max on a macpro?)

That might just make the 12-core out of your budget. Personally I'd see what 32gig RAM on an 8-core would cost first. If you still have money to spare, go for the 12-core. (remember not to buy your RAM from Apple...)

I have 48gig on my 8-core PC. After effects will happily use ALL of it, although how much benefit I'm getting from having 48 rather than 32 I don't really know.

As someone else mentioned, the Macpro's are getting old now, and nobody knows what Apple will do next. Intel has released 8-core chips now, and HP are selling 16-core workstations....

That's a good point about not buying RAM from Apple, maybe I should get separate costs for RAM from somewhere else. What type of RAM would I look for?

The Mac Pro support up to 64GB RAM, the option was there when I was working out the prices.

Thanks.

When I turn it on I get a message saying 'Insufficient RAM, multiprocessing is disabled', so it's impossible for me to turn multiprocessing on anyway :)
