You can view safe zone margins (guides) in the Monitor panel to determine if any text or objects in your project fall outside of the safe zone. When text or objects fall outside of the safe zone, they may be clipped when played back on certain screens. Safe zone margins are for your reference and are not included in previews or export.
Right-click in the Monitor panel, and choose Safe
Margins. A check mark next to the name indicates the safe zone margins
are on.
The standard action‑ and title‑safe margins
are 10% and 20%, respectively. However, you can change the dimensions
of the safe zones in the Project Settings dialog box.
