fit timeline to layers

Fit Timeline To Layers is an After Effects script that automatically adjusts your active composition’s timeline to perfectly match the in and out points of its layers.

I often run into situations where layers extend beyond the current work area—or where the timeline is longer than it needs to be—especially after trimming, importing assets, or making quick revisions. Manually adjusting the work area every time adds friction and breaks flow.

Fit Timeline to Layers removes that step. With a single run, it scans the active composition and resizes the timeline to fit the actual content—no guessing, no dragging handles, no extra cleanup.
