Cameras & capture

Game Capture

Capture a supported game or graphics application.

Before you start

Open the intended collection and layout. For capture or network inputs, have the device or sender available.

Where to find it

Sources > Add > Game Capture.

Use it

Open the scene that will contain the source.
Choose Add in Sources.
Select Game Capture in Create Source.
Enter a name and choose New.
Choose Mode.
For specific-window mode, choose Window.
Set Window Match Priority.
Choose audio, cursor, overlay, and transparency options.
Choose Save and Close (or OK where shown).
Check the source in Preview before taking it to Program.

Controls and additional tasks

Shortcut mode captures the foreground target when its start action is invoked; assign that action in File > Shortcuts. There is no default game-capture key. Limit capture framerate reduces capture load. Protected-game capture and third-party overlays work only where supported. Multi-adapter compatibility can reduce performance. Hook Rate changes how often capture checks for a connection. RGB10A2 Color Space applies to that output format.

Control reference

Control	Use
Mode	Choose whether to capture any fullscreen application, a specific window, or the foreground window by shortcut.
Refresh windows	Refresh the list of currently capturable windows.
Mode	Choose the game or application window for specific-window capture mode.
Window Match Priority	Choose how MCast finds the window again if its handle changes.
Capture Audio	Capture associated application audio where supported.
Allow Transparency	Allow alpha from the captured game when the game provides it.
Premultiplied Alpha	Use premultiplied alpha handling for games that output premultiplied transparency.
Limit capture framerate	Limit capture updates to reduce load when full capture rate is not needed.
Capture Cursor	Include the mouse cursor in the captured game.
Use protected-game capture hook	Use the capture mode required by some protected games.
Capture third-party overlays (such as Steam)	Include supported game overlays in the capture.
Multi-adapter compatibility mode	Use when the game and MCast run on different graphics adapters. This mode can reduce capture performance.
Hook Rate	Choose how aggressively MCast checks for game hook updates.
RGB10A2 Color Space	Choose the color space used for RGB10A2 game output.
Save and Close	Save Game Capture settings. Shortcut: Ctrl+S.
Cancel	Close without saving changes.

If something is wrong

If capture cannot start, check the selected mode/window and the game restrictions. Do not assume every protected game permits capture.

Stop or remove

Hide the source to stop showing its picture. Use its available playback/connection stop control when you need to stop the input itself. Remove the source item from the scene when it is no longer needed. Shared sources can still be used in other scenes.
