troubleshoot: nesting error
I have two layers: a jpg and a small quicktime movie. The jpg is set as a luma matte.
The animation plays fine, but when I nest it the new composition freaks out. I can’t preview any of the frames, but when I scrub through it works (when I let go of the mouse button the preview disappears.)
I have no idea what is going on – I’ve never seen anything like this (it may be relevant to know that the project was originally on AE 7 pro on a PC and now it’s now on CS4 on a mac – I dunno.)
Restarting AE and purging didn’t work. Any suggestions/ideas of what is happening would be GREATLY appreciated!

Make sure Caps Lock is off.
This sounds like OpenGL rendering is enabled, but preview isn’t… not symptomatic of refresh being disabled.

I double checked to make sure I had live updates selected and it was but it seems that Will pointed me in the right direction – when the OpenGL rendering was set on interactive it wasn’t updating properly, but when I toggled the fast previews to always use OpenGL it previews correctly. I dunno why, but it works.
Thanks for your help – I appreciate it.

I would tend to agree that OpenGL is fairly hit or miss with AE. I find it useful mostly for scrubbing through (there is an option to use it for scrubbing updates only in CS3 and later I believe.) It doesn’t render all effects, and frequently it renders colors incorrectly, but it still provides an idea of timing and where you are in your shot if you’re just quickly scrubbing through.
OpenGL is no where near a viable option for playback to review your Comp, and the idea of OpenGL is not to provide this. To expect it to work as Apple Motion’s use of GPU is unreasonable, Apple uses the GPU directly, and can afford to do this because the variations of hardware that it runs on is a lot smaller than AE (Mac-only product!)
