I think I figured out the source of this problem, hopefully Adobe fixes this at some point, meanwhile, maybe this will help folks who run into this “error overflow converting ratio denominators” problem.

Here is the source of the problem, because my initial post wasn’t specific enough.

1. I brought in a quicktime movie and then dragged the movie to the “New composition” icon. This is standard practice for quickly creating a composition based on the properties of a movie.

2. It was here that I received the above mentioned error. It totally makes working in CS3 impossible, and again, it does not do this in AE 7.

3. What ended up fixing it was by *not* dragging the movie file to the new composition icon. Turns out my movie had a strange frame rate of 14.985 instead of 15. Not sure why After Effects interpreted my movie that way, I’m doing some unusual exports because I’m working with screen capture software, so it’s definitely not a traditional workflow.

4. So my solution was to create a composition from one of the AE presets first and then tweak the settings slightly to match my movie properties. Adding my movie clip to this composition gives me no errors and we’re good to go.

Strange solution, but it has worked. Now AE CS3 and I can be friends . . .

Yes, that’s basically what I did, went back to 7.0. Did you get any clues as to what was happening? I filed a bug report with Adobe. It wasn’t addressed in the 8.01 update.
