Screen Capture

Screen Capture source can be used to monitor the images / videos directly from the screen.

It can be used to monitor photo-editing apps like Photoshop, Lightroom or Capture One. It can also be used to monitor video sources like YouTube or Vimeo videos 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 specify the source screen in the settings:

In the new dialog box you can select the monitor that will be used as a source:

You can also limit the frame rate of the capture process.

Then to adjust the captured source you can use the Crop feature – View menu / Crop or Alt+C keyboard shortcut:

This way you can limit the captured area to the monitored image only.

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) 🔶 BETA

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+) 🔶 BETA

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

Features marked with 🔶 BETA are available in beta releases (1.11.x).
