Fixing motion path end position alignment in Adobe After Effects typically involves correcting spatial interpolation, zeroing out layer dimensions, or adjusting the anchor point. A common issue occurs when an object unexpectedly drifts past its final location or misaligns when you copy a shape path onto a layer’s position property. Eliminate Drifting (The “Boomerang” Effect)
If your object moves out of place between two identical end keyframes, After Effects has applied a curved interpolation automatically.
The Fix: Select the final keyframes, right-click, and choose Keyframe Interpolation.
Change the Spatial Interpolation dropdown from Continuous Bezier to Linear.
Alternatively, select the Convert Vertex Tool (G) and click directly on the motion path point in the Composition panel to remove the curves. Match Scale and Layer Dimensions
If you paste a custom shape path into a layer’s position property and it flies off-screen or scales incorrectly, your layer dimensions do not match.
The Fix: Pre-compose your layer (Ctrl+Shift+C / Cmd+Shift+C) and choose Leave all attributes. Ensure the pre-comp matches your main composition size. Re-paste the path onto the Pre-comp’s position property. Use a Null Object Middleman
When matching a moving object precisely to a background layer or complex camera movement, parenting gives you absolute coordinate control.
