    Hi all,

    I have a vexing issue that I’ve ignored or worked around ever since I moved over to Premiere.

    I am trying to slowly tilt down an image followed that then jumps down very fast (2 or 3 frames) followed by a continued slow tilt down.

    On the y-axis, travelling from 972 to 914 over 3 seconds, then 914 to 113 over 7 frames, then 113 to 62 over 3 seconds.

    Yet when I playback the move, the image moves UP to 994 and THEN moves down to 914. On the back end, it does it in reverse

    I’ve deleted keyframes, moved keyframes, changed interpolation to every variation I can think of but it always does the same thing.

    This is what it looks like on export.

    These are the keyframes.

    Thanks all. Sorry if this has been answered before. I can’t find the answer when I search.

    I did the same move with no problems. But i only did a move down.

    It looks like you have keyframes other than y.

    Maybe you have some phantom keyframes.

    I see an indication there is an ‘ease’ of some kind at the end of the move…I do get some pretty weird results when PPro defaults to ‘Auto Bezier’…particularly when there is more than one parameter changing.

    Can you try taking those last keyframes and making sure that their temporal interpolation is set to ‘ease in’ and the spatial interpolation is set to ‘linear’ and see if that cleans it up?

    Are you doing a speed change on the clip ?

    Did you fix the issue ?

    Hey all,

    So the problem is now fixed.

    When I originally look at the keyframe contextual menu, I only examined the temporal keyframes (“scale” does not offer the option of “temporal” or “spatial”). I went back looked at the “spatial” option under the “Motion” attribute and saw that Premiere had decided that I wanted a continuous bezier. When I switched it back to linear it fixed the problem.

    So frustrating that Premiere does this by itself but glad it is resolved.
