I’m having this same problem with v 10.1.4. I am trying to get video to move from position A to position B, stay at position B for a few seconds, and then go back to position A. I have two identical keyframes at either end of the part I want the video to be completely still, but I have the weird drift others have noticed. The adding and deleting keyframes has reduced it, but I I can still see the numbers creeping up and back down. Anyone else experiencing this with this workaround? If I was trying to do precise effects work this would be entirely unacceptable.
It seems pretty ridiculous that the software does this between two identical keyframes! (Yes, both set to linear as well.)
