Creating composition-time markers


    Composition-time markers appear on the time ruler in the Timeline window. After Effects automatically numbers them with a single digit that reflects the order in which you add them. You can place up to ten composition-time markers within a composition. If you remove a marker, the other markers remain numbered as they were.

To add a composition-time marker:

    Do one of the following:

    • Drag from the Time-marker button (the Time-marker button) above the Timeline vertical scroll bar to the desired point in the composition.

    • Move the current-time marker to the position you want to mark and press Shift+a number key on the main keyboard (not on the numeric keypad). The new composition-time marker appears at the current-time position, labeled with number of the key you pressed.

    Note: If the number you press is already used by another composition-time marker, After Effects does not create a new marker. Instead, it moves the existing marker with that number to the new position.

To move a composition-time marker:

    Do one of the following:

    • Drag the composition-time marker to another position on the timeline.
    • Move the current-time marker to the position you want, and then press the number (on the main keyboard, not the keypad) of the composition-time marker you want to move.

To snap the current-time marker or layer duration bars to a marker:

    Press Shift as you drag the current-time marker or a layer duration bar.

To remove a composition-time marker:

    Drag the marker onto the time-marker button (the Time-marker button) on the Timeline window above the vertical scroll bar.
