Todd Kopriva notes tips for improving performance in After Effects in today's post, Hooray for empiricism. Brad Chmielewski tests a couple of performance tips.
The test of the tip on Caps Lock rendering performance is in movie form (embedded below too) at Chmielewski's website Digital Hitchhiker, which is listed in the SqueezeMe.tv feeds. He says that Caps Lock is faster even than closing the Comp and Timeline panels.
Update: in 2003 Stephen Schleicher did some similar tests, and "it looks like completely closing the Comp and Timeline Windows actually improves the speed of the Render. Myth now becomes fact."
