Unneeded motion occuring between 2 keyframes because of bezier curves

[yash-lucid]

video attached.

I have 2 keyframes where motion should be paused, but AE is creating extra bezier curves that it is moving along.

Changing spacial interpolation fixes that and it is now still - however it removes the curved motion from previous keyframes.

See video

EDIT: Using a hold keyframe works as a workaround, but I am still wondering if there is a more normal fix

Hey Yash,

If you're seeing unexpected motion between two keyframes—even though you've set them to the same position—it’s likely due to spatial interpolation using Bezier curves. To clarify: You want the motion path to remain curved, but the animation between keyframes to be linear (i.e., no easing or overshooting).

Here's how to do that: 

1. Select the keyframes in your timeline.
2. Right-click and choose Keyframe Interpolation.
3. In the dialog:
   - Set Temporal Interpolation to Linear (this controls the speed—no easing).
   - Leave Spatial Interpolation as Bezier (this keeps the curved path).

This way, your object will move at a constant speed along a curved path—no unwanted acceleration or deceleration, and no flattening of the curve. Does that work for you? Let us know.

Thanks,

Kevin

Hi Kevin, thanks but as I outlined in the video and my post, changing spatial interpolation to linear while keeping temporal as bezier, fixes the unnecessary motion issue but removes the curves from before. I've already stated it doesn't work.

Maybe using de hold keyframe in the first keyframe.
