Adobe After Effects error: overflow converting ratio denominators
Working on an Intel Mac w/bootcamp. I have installed After Effects CS3 on both platforms (OS x 10.4 & Windows XP). The system has 1 gb RAM and 15 gb available space in the hard drive.
I’m running into a serious issue in After Effects CS3 that I do not get in After Effects 7.0 (on the same machine).
I’m importing a Quicktime movie into a new project, or I should say I’m trying to import. I get the following error on both platforms:
Adobe After Effects error: overflow converting ratio denominators ( 17 :: 19 )
The file is a .mov file 1024 x 768, compressed in animation codec, 15 fps, square pixel aspect ratio and is about 700 megabytes.
Any ideas? Anyone run into this error before?

I ran into the same error running CS3 on my G5 last week. I ended up completing the project in 6.5.

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.

I was making a slideshow using 360 jpeg images. As soon as I keyframe assistant>distribute layers I got the error message. Since I was on a tight deadline I really didn’t have time to mess with it. The same file worked fine in 6.5. Now that the project is finished, I may go back and poke around to try to figure out just where the problem is.

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 . . .

Using cs3, I just came across this problem importing an f4v i had renamed to a mov. It had some screwed up fps showing in the interpret footage panel – i just changed to back to its original in this case 25. Seemed to have fixed it.

To Fix: Change the frame rate of the comp that has this problem to a whole number.
IE: My comp was strangely set 30.03. Setting it to 30 and hitting return fixed this. You’ll likely need to move all of your key frames back to their closest frames because they will be offset by the old decimal places in the frame rate.

Crikey I love Creative Cow.
Five minutes ago I was screaming at the screen. Now, having read and tried your fixes, I’m as calm as a cucumber and back in love with After Effects.
Changed the frame rate in ‘interpret footage’ for some reason it was 23.5 and not 25.
Many many thanks!!!

FWIW – this error still occurs in CS5. I was copying a clip, which had been sped up to 750%, from Premiere into AE. Didn’t give me the error once I’d put the clip speed to 100% in Prem and tried copying and pasting again.
