# Monitoring Multiple Elements Simultaneously

You can use the Triptych Player to monitor multiple elements simultaneously by locking all Triptych positioners together. For example, you can view the outgoing, current, and incoming shots simultaneously to see each shot in context. By locking the positioners, you can scrub through the timeline while each Triptych Player window updates. This is useful for seeing the results of edits to the current shot. For example, you may have dissolves at the head and the tail of the shot and want to see the result of slipping the current shot.

To use the Triptych Player to monitor elements on the same layer:

1. Display the Triptych Player.
2. Select Free in the Triptych View Mode box.
3. Click anywhere in a Player window to make it active.

   A red border appears.

4. Move the focus point to the layer you want to use by dragging it or using the up and down arrows.
5. Select Locked in the Triptych View Mode box.
6. Move the positioner.

   All three positioners move simultaneously and each Triptych Player window updates.
