copy markers to timeline

Copy Markers To Timeline is an After Effects script that copies all markers from selected layers directly onto the composition timeline. Markers retain their exact timing, comments, durations, and label colors. When multiple markers from different layers align at the same time, a single standard marker is created at that position. This makes it easy to translate layer-based timing into global composition markers without manually recreating each one.

Currently tested and working with After Effects 2024 and 2025.
