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:

Crop the captured area

On current Windows builds, Crop also affects scopes correctly when the input uses Windows Graphics Capture.

Troubleshooting

macOS Permissions

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

Capture driver

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 Crop updates the overlay but scopes still analyze the full frame on Windows, update OmniScope to a build that includes the Windows Graphics Capture crop fix or switch to ScreenCaptureWinDX11 as a temporary workaround.

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)
