FAQ: Why does my layer (camera) move back and forth between keyframes of equal value?

-

in cases, auto bezier spatial interpolation position keyframes can cause undesired back-and-forth (boomerang) motion between 2 keyframes equal values. in such case, can change earlier keyframe use hold interpolation or change both keyframes use linear interpolation.

 

to change default linear interpolation, choose edit > preferences > general (windows) or after effects > preferences > general (mac os), , select default spatial interpolation linear. changing preference setting not affect keyframes exist or new keyframes on properties keyframes exist.

 

for more information, including links video tutorials demonstrate problem , solutions, see "controlling change interploation" section of after effects help.
