Join Chris Meyer for an in-depth discussion in this video Preserve frame rate, part of After Effects Apprentice 08: Nesting and Precomposing.
Chris Meyer: I'd like to share with you one last gotcha that can crop up when you nest one…composition into another, as well as how to fix it.…Normally, a composition's frame rate rules all. This is the speed at which new…source material's sampled from the original files in your computer and which new…animation positions are calculated.…It's also the rate used by effects that may randomize on every new frame of your composition.…I started out with frame rate of 10 frames a second on this comp, which gave me a…little bit of a stop motion sort of look.…But let's say I wanted to push that even further.…
Press Command+K or Ctrl+K and set this down to 3 frames a second. 0 to RAM…preview and now I have a much slower stop motion look to this animation.…However, whenever a composition is nested into another comp, that later comp's…frame rate takes over and this frame rate is now used for this comp as well as…any comps nested into this comp.…In this particular case I'll RAM preview and I've lost my exaggerated stop…
The After Effects Apprentice series was created by Trish and Chris Meyer. These tutorials are designed for After Effects CS4 through CC, and can be used on their own or as a companion to the Meyer's book, After Effects Apprentice.
- Grouping layers by nesting and precomposing
- Identifying and solving render order issues
- Navigating composition hierarchies
- Editing a precomp while viewing the result in another composition
- Preserving the frame rate of a nested composition

Q: This course was updated on 11/29/2012. What changed?
A: We added a new chapter, "Render Order Exceptions." It contains four new movies: Continuous rasterization, The Transform effect, Collapse transformations, and Compound effects. We also added a movie that shows our premium subscribers how to use the exercise files, including the new exercise files designed for After Effects CS6.
