newbie Cached frames question (cs4)
I have a newb question about image caching and key frames. I’ll use an example to describe my issue.
I’m animating a camera in a 3d space for a depth of field look. when I create an animation with say 2 keyframes and then I add two in between the original keyframes, AE seems to keep the tween value properties in between(to some extent), even after I add the two new keyframes. And it gives a yoyo animation in between. So for example, I have an animation that goes from xposition=20 to xposition=100 Then I add 2 “hold” keyframes at xposition=50
It still does a yoyo animation in between the two x=50 keyframes even though on both of the middle keyframes the values are exactly the same. I have tried clearning the image cache, and moving the keyframes around to “clear” them, I have also tried to paste over them. I don’t know why this happens. Any ideas? -

there are 2 types of interpolation that effect keyframes, temporal and spatial… the problem you are seeing is that the temporal interpolation is set to hold (not change over time) but the spatial is set something else (probably auto bezier) and is being influenced by the values of surrounding keyframes.
you can right click on a keyframe and choose ‘keyframe interpolation’ and change the spatial interpolation to linear.
also, here’s a tutorial that does a nice job of explaining the effect you are encountering:
