Speed is not constant between linear keyframes

Hello, I am doing an animation where I pull out from a fixed point in a still image, by adding keyframes to both position and scale. The animation is doing what I need it to do with one exception: even though the keyframes are set to linear, the speed between them is not constant. In almost every case the section in between each keyframe starts off slow, then ramps up faster and faster until it hits the next keyframe and then slows to a crawl again. This repeats over and over between all keyframes. I am trying to have a constant speed between the keyframes.  Thanks.

Make sure spatial and temporal is set to linear.

Or do one property in Motion the other with Transform effect.

All keyframes, both spatial and temporal are set to linear.

Transform doesnt do what I need to do. I just need keyframes to work with constant speed through the interpolation.

You can use keyframes from the Transform effect just does the same as the fixed effects.

Perhaps you can achieve better results by doing this inside After Effects. There, you can parent layers together.

 

I remember doing something similar using this tutorial from VideoCopilot: https://www.videocopilot.net/tutorials/earth_zoom/

 

Hope this helps.
