Hey. it would help if you also tell the version of After effects and what's the exact error message it's throwing ?it would be better if you post a screenshot of it.
Files on a DVD are not meant for editing.
Maybe even more difficult if you are trying to edit a commercially released DVD as well!
The error that comes up is:
After Effects error: overflow converting ratio denominators.
(17 :: 18)
And I'm using Adobe After Effects CS5. And if it makes it more clear, the DVD movie was converted to avi format. So it's just one file.
Thank you guys for your replies!
Found the solution!
I found the answer on a post on http://Creativecow.net
"...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 . . ."
Anyways, thank you guys for your replies!
Glad it worked . The other solution given in the link is a better approach i think. i.e changing the frame rate to a whole number .
