AE CS4 Incredibly Slow Render Times
Hi
I’m fairly new to AE so i’m not sure what i should be expecting in regards to Render times but they seem to be incredibly long. For a 1’30” project – it takes over 20hours with motion blur on and about half that without.
Here are my specs
Model Name: MacBook Pro
Model Identifier: MacBookPro3,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2.6 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 4 MB
Memory: 4 GB
Bus Speed: 800 MHzThe project is fairly complex (in my opinion) with about 8 layers of video animating in 3d space with camera moves.
I’m exporting to Quicktime in Full Res HD (1920 x 1080) although i’ve tried motion-jpeg and it doesn’t seem to be that much quicker.
I’ve tried fiddling with the Multiprocessor settings and although it does make some difference, the render times still seem to be very long.
What should my multi-processor settings be for a laptop of the above specs?
Also, although i have 4gig of RAM installed when i render out the message in the bottom left says it’s only using 13% of 3gb of RAM. Why is that? It seems AE isn’t using all the resources at it’s disposal?
Obviously, i’ve tried quitting other apps / background processes and i have over 70GB left on the hard drive.Any advice / tips would be greatly appreciated as at the moment i’m finding the long render times make the program unusable.
Thanks

yes thanks i\’ve read various posts including the ones you mention. With multi processor off it seems to be even slower. My footage isn\’t in any of those codecs either. Is animation a very slow format to render to?

You may have tried this already. I’m using the same MacBook Pro laptop. After upgrading to 10.6.3, I noticed almost a doubling of render times on a comp I use every week. I found that I had turned on “Render Multiple Frames Simultaneously” at some point. I turned this off and restarted AE and my render times dropped dramatically.

You can also render faster using your Terminal and ‘aerender.’ Simply set up your project to render with the desired settings and save the project. Open Terminal and drag the ‘aerender’ script (found in Applications > After Effects > aerender) into the terminal window. Then hit space bar then type ‘-project’ and drag your AE project file into the terminal and hit the return key. Your project will then render fairly fast and you will still have enough remaining ram to continue working on your computer without it slowing down. This is also a great way to render multiple AE projects at once!

I use a macpro 3.A 2x 2.8 GHZ quad-core Intel Xeon with 6 GB of RAM, And me the same problem occurs, I try to make a render of a project rather heavy to 1920 x 1080, Composed of various compositions (7) Las which use Trapcode form, Lux and shine, And takes about 11 hours to render 42 seconds.
Is normal or a fault on my machine?
Thanks.
