After Effects Strange Camera Movements...
on Sep 15, 2010 at 8:21:01 pm

I have been noticing that on during some camera movements, the camera will kind of "extrapolate" movement between two keyframes and wiggle all over the place, moving randomly in different directions despite the absence of keyframes where it is moving.

Is there any way to prevent this? It is driving me crazy!

maybe change interpolation from bezier to linear?

Not to worry. Not one bit.

You obviously have two keyframes with identical values. Just highlight the first of these two keyframes, the incoming one, then right-click and find the Toggle Hold Keyframe command. AE will make a combination Bezier-incoming and Hold keyframe.

The result: the motion eases in, holds rock-steady, then eases out and continues the motion when it encounters the second keyframe

THANKS! That was very helpful, but it almost defeats what am trying to do. I have multiple different "scenes" layed out on a big common background canvas, with the camera flying to each of them, slowly zooming in or panning or zooming out, then swooping off to the next one. When I HOLD the keyframe, it ceases all movement until the next set of keyframes, where the camera moves on to the next destination.

Okay, then play with the Bezier handles on the keyframes to un-weird the weird camera movement.

Ok, when I turn the graph editor on there are no keyframes? I have done all the keyframing by "transforming" the camera. Is this incorrect?

Thanks again!

Never mind. I had to select the desired layer. Silly me!

This clears everything up though, thanks for the help Dave!

For others coming to this thread, I'll provide a link. See the section of this page about "boomerang" motion.
