Overlays
Overlays let you display PNG images on top of the Source Signal viewer — useful for safe-area guides, framing references, branding, or composition grids.

Opening the Overlays Window
Open the window from the menu:
Options > Overlays
Loading an Overlay
Click Load Overlay… in the Overlays window
Select a PNG file (alpha transparency is supported)
The overlay appears in the list and is displayed on top of the Source Signal viewer
You can load multiple overlays and switch between them.
Removing an Overlay
Select an overlay in the list and click Remove selected overlay.
Selecting an Overlay in Source Signal Settings
You can also select which overlay to display directly from the Source Signal scope settings, without opening the Overlays window.

Built-in Overlays
The Source Signal scope also includes built-in overlay options accessible from the scope's context menu:
Title safe — broadcast-standard safe area guides
Thirds — rule-of-thirds grid
Crosshair — center crosshair
Tips
Use transparent PNGs — the alpha channel controls which parts of the overlay are visible
Design overlays at the same resolution as your source for pixel-perfect alignment
Overlays are saved in your layout, so they persist across sessions
Useful for letterbox guides, watermark placement, and aspect ratio markers
