3d Camera Animation in AFX
Macintosh: AFX CS3:
When animating the “position” [x,y,z] of a camera, and when you add key frames to a time-line linearly no bezier curves are added. But if you go back and add a “tween” keyframe AFX automatically makes bezier curves associated with the movement, which in my opinion causes the camera to do unexpected things. When you look at the “graph editor” view the line between the two key-frames looks like a peaked roof. How do you eliminated the “automatic” bezier-ing of key-frames? Or how do you add handles that will do this in the graph editor? Or any other trick or knowledge of this would be helpful. Thanks in advance.

from the “Controlling change with interpolation” section of After Effects Help:
“To change the default to linear interpolation, choose Edit > Preferences > General (Windows) or After Effects > Preferences > General (Mac OS), and select Default Spatial Interpolation To Linear. Changing the preference setting does not affect keyframes that already exist or new keyframes on properties for which keyframes already exist.”

It’s a dark secret! 😉
Todd’s right and that should be a first-off setting. But eventhough the spatial keyframes are linear, you may still experience kinks if your tempoal keyframes are not linear or hold. To solve such problems, you’ll have to convert the temporal keyframes back to linear, say a prayer (with your eyes closed) and then massage the temporal keyframes again. 9 out of 10 times this solves the problem.
The trick is to work linearly, across two adjacent keyframes, along the timeline when animating the camera rather than placing a bunch of keyframes and then going back to fine-tune them at one go.
