Camera Problems
Hello.
I am having an issue with my camera in AE (cs4 version). When I track my Z in far, then go to track it out it will go in the opposite direction before going in the right direction. In other words, I track from
-1244.4 to -4.4. Then when i try to track from -4.4 to -148.4 it will for the first frame jump to 46.8 then track to -148.4, therefore going to the backside of the project then coming back to the front…Anyone know how to fix this? Any help would be greatly appreciated.
Thanks,
Willem.

This sounds like an interpolation issue. Basically, AE is trying to smooth out the spatial motion of the camera, and the position is sort of “rubber-banding.” Try right-clicking on the keyframe in the middle, opening the keyframe interpolation window, and setting spatial interpolation to linear. This will mean the if your keyframes are not lined up on X/Y, the camera will appear to “slide” rather than “arc” into place. If this is a problem for you, there are other ways to get around this, but for now, this is the easiest method. If you do need to animate in other directions, try breaking out X Y and Z into different properties (Andrew Kramer has a tutorial on this I believe.)
I recommend reading up on keyframe interpolation in AE if you’re interested in better understanding your problem. This is a good resource, it says CS3, but the concepts are for the most part the same in later and earlier versions.
