Issue with speed ramping still images

Hopefully somebody can help me because I am about to tear my hair out.

I'm trying to figure something out in Premiere that seems like it should be super simple but apparently isn't. Basically, I want a photo to quickly slide into the frame from the top and then suddenly slow down and start panning much more slowly and then rapidly zoom out of frame at the bottom. I hope you understanding what I'm saying.

I figured it would be as easy as keyframing it via the Position property, but for some reason as the photo is doing the slow pan, when the time indicator gets close to the next keyframe there's this weird thing that happens where the image changes directions. Basically I will set the position property for the next keyframe and then it overshoots the mark along the way, realizes it overshot the mark, and then heads back in the other direction. It's very strange.

I've tried it over and over and always get the same result, across multiple versions of Premiere CC.

Any help would certainly be appreciated.

    It's such a common effect that I assumed everyone would just know what I'm talking about.

    But after several hours of frustration tonight, I think I just figured it out. Seems that the keyframes all need to be set to Linear for it to work correctly. I had four keyframes and for some reason the middle pair would default to Auto Bezier under Spatial Interpolation. I am not a seasoned enough Premiere user to even know what that means, but I just started trying stuff and it seems setting Spatial Interpolation to linear fixed it.

    It was a truly strange issue. I'm not sure why ANY setting would cause the effect of an image reversing course to backtrack to the next keyframes Position setting.

    In any case, I think I'm good now.

    Really this is happen when your Bézier Curve jump over the next keyframe value, so your curve must set in the right position to get the smooth movement without reversing issue

    This went over my head a bit but thanks for the info. I'll have to look into this some more.

    I'm not sure why anyone would want that functionality--for it to overshoot the specified value and have to come back to it.

    it's  better if you can put some screenshot or video preview so can understand your issue

    Position and scale interpolation keyframes can give strange behavior when using together.

    Might want to nest in between.
