Image borders movement when moving still photo

Hi. I have a problem when applying a keyframed transform on a still photo, to move it on the frame
The thing is that if I move the picture, in this example, from left to right, the picture moves on every frame, but the border just moves each 10th frame

I realize I can fix this by recreating the transform in Fusion, but maybe someone knows a better way to do this without using fusion transform? I already have maybe a hundred of pictures with this kind of movement. Is there a way to select the interpolation between frames with still images?

Thanks
