Specify when a layer appears in a video or animation (Photoshop Extended)

You can use various methods to specify when a layer appears in a video or animation. For example, you can trim (hide) frames at the beginning or end of a layer. This changes the layer’s start and end points in a video or animation. (The first frame to appear is called the In point, and the last frame is called the Out point.) You can also drag the entire layer duration bar to a different portion of the timeline.

  1. In the Animation panel, select the layer.
  2. Do any of the following:

    • To specify the In and Out points of a layer, drag the beginning and end of the layer duration bar.

    • Drag the layer duration bar to the section of the timeline where you want the layer to appear.

      Note: For best results, drag the layer duration bar after the bar has been trimmed.

    • Move the current-time indicator to the frame you want as the new In or Out point, and from the Animation panel menu, choose Trim Layer Start To Current Time or Trim Layer End To Current Time.

      This shortens the layer duration by hiding the frames between the current-time indicator and either the start or the end of the layer. (Re-extending the ends of the layer duration bar reveals the hidden frames.)

    • Use keyframes to change the layer’s opacity at specific times or frames.

    Note: To delete footage in one or more layers, use the Lift Work Area command. To delete a specific duration from all video or animated layers, use the Extract Work Area command.
