Summary
CutWire Prism is a free, open-source node-based live video mixer for volunteers, streamers and small venues. It mixes two decks with a crossfader, AUTO and CUT controls, per-deck speed and multiple transitions. Sources can include video files, images, slideshows, cameras, screen captures, shaders, HTML, text, Lua, NDI and a phone camera connected by QR. A Remove BG process uses MediaPipe segmentation to remove webcam backgrounds without a green screen. Prism supports Lua 5.4 scripts and GLSL fragment shaders, including audio-reactive presets. The mixed program can be sent to a projector window, NDI, a virtual camera or a recording; it can also appear as a virtual camera in OBS, Zoom or a browser. OBS can control Prism over WebSocket. One-click controls provide blackout, pausing the current frame and a Stay Tuned overlay. Prism runs on Linux and Windows; macOS requires a source build and has no virtual camera output. The maker describes the project as early and under active development.
Who it is for
Prism suits volunteers and small venues producing live video, as well as streamers who need a mixer with varied sources. Its intended settings include school events, churches, theatres, clubs and local sports broadcasts.
