Changing X position keyframe is affecting Y?
I’m trying to put some effects into an image inside a video. The effect that I’m trying to achieve is a Y-axis wipe where the image has two modified X-keyframes (i.e first X keyframe is at -100 and the other one comes about 5 seconds later at 100).
However, leaving the Y-keyframe completely untouched, I see the image move up a bit, and halfway between both position keyframes, the y-keyframe moves up.
those are the beginning and second keyframes.
The issue goes away after I remove the last position keyframe (moves it back to (645, 295)
I noticed that the problem only lasts for one keyframe if I duplicate keyframe 2 one keyframe before it (the frame it occurs in is between keyframe 2_1 and keyframe 2_2.
I have linear checked, I Tried ease out and ease in, no luck 🙁

Wow, that worked… I right clicked the keyframe, selected spatial Interpolation, and then linear!
Can’t believe it was that easy. -
Ugh! I am now having the same problem, and I think it’s not nearly as easy as you say. Adobe’s keyframe handling code appears to be written by a group of programmers who (1) don’t know each other, and (2) don’t really understand basic concepts of model-view-controller programming. I’m looking at the Position keyframe controller in the Motion part of Video Effects. The position is a two-dimensional parameter, meaning it can vary in terms of X and Y. The display of the keyframe values along the timeline show (and control) only the X parameter.
Something has gotten into my Y parameter that is messing with my image position, but nothing I seem to try exposes where that’s coming from. All I see is the stupid X parameter, and neither a graphic indication nor a textual one that something is funky with the Y parameter.
If only the XML output from Premier Pro could be easily parsed by humans, I might be able to tell what is going on. But now I have to decide whether to manually write down all the keyframes I currently set, delete them all, and try to re-enter, or what.
