Virtualize Your Webcam (Mac)
On macOS, many webcam effects and background features are now built directly into the system, so no additional software required.
Use built-in video effects (macOS)
Open your Crowdcast event and enter the greenroom.
Click the Control Center icon in your Mac menu bar (top-right).
Select Video Effects.
Choose from available options such as:
Portrait (background blur)
Studio Light
Reactions
Make sure your desired camera is selected in Crowdcast.
These effects will automatically apply to your video feed in Crowdcast.
When to use additional tools
If you need to:
Share pre-recorded video
Add overlays or scenes
Switch between multiple sources
You can connect live streaming software with RTMP mode.
Virtualize Your Webcam (Windows)
Virtualizing your webcam on Windows requires third-party software. This allows you to share media, apply effects, or customize your video feed before going live.
Why use a virtual webcam?
Add custom backgrounds or blur effects
Share slides or videos directly in your camera feed
Include branding, overlays, or layouts
Use advanced production tools not built into Crowdcast
