I have always been using the multiprocessing option in after effects, for faster renders and ram previews. But recently when I have tried to render a composition, or make a ram preview it's been stuck at "initializing background processes". Disabling multiprocessing makes it able to render, but it's painfully slow when rendering large compositions since only 1 core is being used.
Here's a paste of the details in multiprocessing.
|Installed RAM: 15,96 GB||Current RAM Usage: 0,81 GB||Allowed RAM Usage: 10,96 GB|
|Process ID||Application Name||Min Needed Memory||Max Usable Memory||Max Allowed Memory||Current Memory||Current Priority|
|4872||After Effects||0,00||0,00||10,96||0,00||3 - Low|
I am using AE CS6 188.8.131.52
Here are some system specs of my PC.
OS: Windows 8
Installed RAM: 16GB
Processor: Intel I7-3770 @ 3.40GHz
GPU: Nvidia GTX 680
I am running after effects on a 120gb ssd drive.
If the comp doesn't render, it contains a feature, setting or effect that is not MP compatible. Could be anything from using a certain CoDec fpr a clip to e.g. OpenGL effects like Optical Flares or MB Looks.
