What is the term for Spatial Interpolation in After Effects?

Spatial interpolation in Adobe After Effects refers to how keyframes affecting an object's position are calculated and represented over time. Position is the term associated with manipulating the spatial attributes of an element, determining where it is located in the composition’s coordinate space.

When you create keyframes for position, After Effects interpolates the movement between these keyframes to create smooth transitions. So, if you animate the position of a layer from one location to another, After Effects uses spatial interpolation to determine the path the layer will take during that animation.

The other options, while important properties in After Effects, are not related to spatial interpolation. Rotation concerns the angle of an object, scale refers to its size, and opacity dictates transparency, none of which affect an object's position or its movement through space. Therefore, position is the appropriate choice for this term related to spatial interpolation.
