Layers

Display Capture

Capture application windows or your entire desktop as a layer source.

Display Capture grabs content from your screen — a specific application window or an entire monitor.

Add a Display Capture

  1. Open the Sources Panel on the left.
  2. Available displays and windows appear in the list.
  3. Click one to add it to your scene.

For fullscreen games, consider Game Capture instead — it has auto-detection enabled by default.

Changing the Source

After adding a Display Capture, you can switch what it captures:

  1. Select the Display Capture layer.
  2. Open the Inspector PanelProperties tab.
  3. Choose a different window or display from the dropdown.

Audio Track

Display Capture can include audio from the captured application:

  1. Select the Display Capture layer.
  2. In the Inspector Panel, enable Add an audio track for the source.
  3. Toggle CUE to monitor the audio through your headphones.

Performance Tips

DualStream shows an FPS indicator for capture sources to help spot issues:

  • A green bar below the target line may indicate a rate mismatch or system bottleneck.
  • If a specific source looks choppy but the overall FPS is fine, the issue is with that capture device — not DualStream.

Common Causes of Capture Lag

  • System CPU or GPU bottleneck (e.g., demanding game running)
  • Display capture of a minimized window (some apps stop rendering when minimized)
  • External AI filters running on the captured application
