- Markers in Adobe After Effects are a useful tool for storing comments, metadata, and other information about specific points in time in a composition or layer.
- Composition markers appear in the time ruler for the entire composition, while layer markers appear on the duration bar of a specific layer.
- Both types of markers can hold the same information and can refer to a single point in time or duration.
- Composition markers in After Effects correspond to sequence markers in Adobe Premiere Pro, and layer markers in After Effects correspond to clip markers in Adobe Premiere Pro.
- Markers can be converted to web links, chapter links, or cue points when rendering a composition, depending on the output format and settings specified in the marker dialog box.
- They can also be exported as XMP metadata.
- The default comment for a composition marker is a number, while the default comment for a layer marker is nothing
- You can add markers during a preview or audio-only preview to mark significant points in the audio track of a layer.
- To view or edit marker data, double-click the marker or right-click (Windows) or Control-click (Mac OS) the marker and choose Settings.
- To move a marker to a different time, drag the marker or double-click it and enter a new time in the dialog box.
- To set the duration of a composition or layer marker, drag the marker’s out point in the Timeline panel.
- To set a marker’s duration by dragging, hold the Option (macOS) or Alt (Windows) key, then click the marker icon and drag to the right.
- To change the duration of a marker, click and drag the marker out point icon without holding any keys.
