Video Output View

The Video Output view shows a composite preview of all surfaces rendered onto their assigned video sources. This represents what the video processor would receive as its input signal.

What You See

The view displays the full video source resolution with all surface instances composited in their configured positions. This includes:

• Test patterns rendered at full resolution
• Video and image content scaled according to each surface's scale mode
• Logo overlays
• Multiple surfaces layered on the same video source

Video Source Selection

If your project has multiple video sources, use the dropdown to switch between them. Each video source renders independently at its configured resolution.

Background Color and Opacity

Each video source has a configurable background color (set per-source in the Outputs sidebar panel) plus an opacity slider (0–100%). The background fills any region of the output canvas that isn't covered by a surface instance.

• At 100% opacity (default), the background is fully solid — what the LED processor sees outside surface coverage.
• At lower opacity, the background renders with real alpha. This carries through to:
  • The Surfaces and Mapping views, where the video-source area visibly fades toward the canvas backdrop
  • The Project page thumbnails
  • Bulk PNG exports — the exported file has a transparent (or partially transparent) background, useful for compositing the output over other artwork
• At 0% opacity, the canvas is fully transparent in exports; the live preview shows the underlying view background.

Navigation

• Pan — Click and drag to move around the output
• Zoom — Scroll wheel to zoom in and out
• Fit — Click the fit button to frame the full output

Resolution Display

The current video source resolution is displayed in the toolbar (e.g., "1920x1080"), making it easy to verify you're looking at the correct configuration.

Real-Time Preview

The Video Output view updates in real-time at up to 60 FPS, showing:

• Animated test patterns (scrolling lines, gradient sweeps, etc.)
• Video playback at the correct frame rate
• Panel Map overlays with live wiring data

Use Cases

• Pre-visualization — See exactly what the processor will receive before connecting hardware
• Content verification — Check that video content is properly sized and positioned
• Test pattern inspection — Zoom in to verify test patterns at pixel level
• Client presentation — Show stakeholders what the LED wall will display
