Color correction process

[Erik Lindahl]

Preparering your media will greatly affect the rending speed in After Effects for sure.

Input footage size can severely affect rendering speeds of simple i/o operations, transformation-effect, and esp. if you add motion blur or filter to the footage. It’s always recommended to prep media as much as you can.

Other things to consider is applying filter to the layers of footage or as an adjustment layer in the comp. Sometimes the later can decrease rendering times considerably as you are affecting the comp-size rather than the footage size. If doing a pan / zoom over say something massive – a 12 000 x 12 000 image in a 720×576 PAL-comp, adding effects such as leveles, curves, exposure and so forth to the actual footage will kill rendering times. Simply adding it to the comp in an adjustment layer will rendering X-times faster.

Prepping footage prior to adding them to AE can even increase rending quality at times as well (avoiding aliasing or moarè due to large down-scales).

I agree with Dave. Here is a post that collects links to Andrew Devis’s color correction tutorials.
