via @Lester Banks is another Felt Tips After Effects tutorial video on rendering. He previously posted Chain Rendering. Felt Tips comments that this tip is not exhaustive even at 27 minutes:
"There are no hard and fast rules, so this is a collection of some of my techniques that I've been using for the last 15 years or so using After Effects. It centres around setting up a render process early in a project, using image sequences until the very final stage. This has some surprising advantages.
I also cover the use of background renderer, creation of output modules and render settings templates, memory, multi-processing and disk-cache preferences, as well as showing a basic preset for rendering FLVs and Quicktime H.264 out of After Effects."
