stretch layers

Stretch Layers is an After Effects script that proportionally scales the length of multiple selected layers at once.

When a group of layers needs to fit a new duration—whether extending, compressing, or revising timing—doing it manually is slow and error-prone.

Stretch Layers lets you define a new total duration (in seconds or frames) and automatically scales all selected layers proportionally from the earliest layer’s in-point, preserving their relative spacing. It’s like Option-dragging multiple keyframes—but for entire layers.
