CutWire Prism vs PRISM Live Studio

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 include video files, images, slideshows, cameras, screen capture, shaders, HTML, text, Lua, NDI, and a phone camera connected by QR. Its Remove BG process uses MediaPipe segmentation to remove a webcam background 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 serve as a virtual camera in OBS, Zoom, or a browser, and OBS can control it over WebSocket. One-click controls include blackout, pausing the current frame, and a Stay Tuned overlay. Prism runs on Linux and Windows; macOS requires a source build and lacks virtual camera output. The project is described as early and under active development.

PRISM Live Studio lets creators broadcast live, record video and take photos using effects and media such as stickers, images and music. Desktop apps for macOS and Windows provide customizable scenes, media and game sources, drawing mode, free widgets and in-app live chat; the listed maximum resolution is 4K. Desktop users can stream to one channel on the free plan or up to six with PRISM Plus, which costs $9.99 a month. Mobile features include screencasting, voice-responsive VTuber avatars, viewer chat, camera effects, animated text and overlays. The mobile product page lists up to six simultaneous streams at 1080p and 60 fps. Named destinations include YouTube, Facebook, CHZZK, NAVER Shopping Live, BAND, NAVER TV, SOOP, Twitch and custom RTMP URLs. PRISM Lens adds virtual backgrounds and face retouch effects and can work as a virtual camera in Zoom and other programs. The free PRISM Basic plan includes dual output to two channels and 30 minutes of 3D VTuber face tracking, with ads, watermarks and outros displayed.
