Screen Capture

Screen Capture allows you to monitor images and videos directly from the screen. Use it with photo-editing apps like Photoshop, Lightroom, or Capture One, or to monitor video sources like YouTube or Vimeo directly.

In 1.11.25+, OmniScope defaults to ScreenCaptureKit on macOS 12.3+ and Windows Graphics Capture on Windows 10/11. You can switch drivers in Input Settings if needed.

Once the Screen Capture is connected, you can select the source monitor and configure the frame rate in the Input Settings:

To limit the captured area to the monitored image only, use the Crop feature — View > Crop or Alt+C:

macOS Permissions

If you don't see an image on macOS, make sure OmniScope has Screen Recording permission:

Screen capture driver defaults can be changed if compatibility issues appear.

If screen capture doesn't work as expected, you can change the capture driver in Input Settings:

If you are using older OmniScope version, you can change this in the config file:

1. Go to Options / Open Logs

2. Close OmniScope

3. Edit file config_1_19.json

4. Find a line: "screencapture_type": "ScreenCaptureWinDX9", And change it to: "screencapture_type": "ScreenCaptureWinDX11",

5. Save the file & restart OmniScope

There are several options that can be used for screencapture_type:

Windows:

1. ScreenCaptureWinWGC - Windows Graphics Capture (default in 1.11.25+ on Windows 10/11)

2. ScreenCaptureWinDX11 - GPU accelerated using DirectX 11 (low latency, recommended on older Windows 10)

3. ScreenCaptureWinDX9 - GPU accelerated using DirectX 9 (most compatible, recommended on Windows 8 and older)

4. ScreenCaptureWinGDI - without GPU acceleration (safe fallback if the above don't work, but it is the slowest option)

macOS:

1. ScreenCaptureKit - Modern macOS capture API (default in 1.11.25+ on macOS 12.3+)

2. ScreenCaptureMac - Legacy capture (compatible with older macOS versions)
