Scrolling in AE with different height sources

Ok, I never liked Algebra; perhaps somebody can give me a hint...

I've some Illustrator sources in After Effects for scrolling end credits--normal stuff, do the position keyframes, etc. The Illustrator files are different heights--some are taller (more text) than others. What's the best way to calculate the duration/keyframe locations, in order to ensure that the different files appear to be scrolling at the same speed? Right now I'm just tweaking the key frames with the comps stacked, and eyeballing the scrolling to make sure nothing is lagging behind.

Surely there's a better way...

Thanks,
Matt

Scrolling

Hi Matt - sorry my algebra isn't great either, so I would be tempted to do iether of two things;
Go into Illustrator and make one long thin graphic of all the titles imported in sequence then just keyframe the beginning and the the end positions of that single layer in AE
or
Convert all the layers to 3D, stack them above one another in order, create a camera and keyframe the beginning and end positions of the camera as it moves down them.
(or learn algebra I suppose:-)
Hope that might help?

Hi Matt,

A variation on Gregory's second suggestion above might be to stack the layers then parent them all to a null object and set the keyframes on that null.

Yes, I think the null is the best tool in After Effects.

Well, I eyeballed it for this particular project, but the next one (which is in flight, so not long to wait), I will definitely give the null thing a go! That sounds really intelligent. Probably why I didn't think of something like it...Eventually I'll get through my "Learning After Effects" book.

Thanks,
Matt
