Taking and viewing a snapshot
When you want to compare one view to another in the Composition, Layer, or Footage panel, take a snapshot. For
example, you might want to compare two frames in different locations in a movie.
When working with snapshots, here are some tips to keep in mind:
• Snapshots taken in one kind of panel can be displayed in another kind. For example, you can take a snapshot of a
Layer panel and display the snapshot in the Composition or Footage panel.
• Displaying a snapshot does not replace the content of the panel.
• If the snapshot has a different size or aspect ratio than the panel in which you display it, the snapshot is resized to
fit the current view.
• Snapshots are for reference only and do not become part of the layer, composition, or rendered movie.
To take or view a snapshot
Do one of the following:
• To take a snapshot, click the Take Snapshot icon at the bottom of the panel. If you have a sound card installed,
a sound is generated when you take a snapshot.
• To view a snapshot, click and hold the Show Last Snapshot icon at the bottom of the panel.
To take and view multiple snapshots
Do any of the following:
• Hold down Shift and press F5, F6, F7, or F8 to take separate snapshots.
• Press and hold F5, F6, F7, or F8 to view the corresponding snapshots.
• To purge a snapshot, hold down Ctrl + Shift (Windows) or Command + Shift (Mac OS) and press F5, F6, F7, or F8.
