CamMask vs CutWire Prism

CamMask is virtual webcam software for Windows and macOS that adds effects to video for chats, websites, and Flash. Its feature list includes thousands of effects covering distortions, filters, backgrounds, particles, emotions, and animations. A face-changing tool analyzes a face and expression before combining another face into it. Users can replace backgrounds, draw with adjustable paintbrush, fill, eraser, and stamp tools, and add fixed or scrolling text such as dates and times. Video sources include a webcam, video gallery, image gallery, desktop, or gradient and solid colors. Snapshots and video recording are supported, with a manager for reviewing clips or sharing them to Flickr or YouTube. Picture-in-picture provides two-channel and 2x2 modes. Output can reach 720p or 1080p, with up to six preset viewports. CamMask Free costs nothing; CamMask Pro costs $34.99, paid once and removes the watermark while adding listed effects and controls.

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.
