EZ-CorridorKey vs FuzzPuppy Video Background Remover

EZ-CorridorKey is a free desktop GUI for CorridorKey, an AI chroma keyer that separates foreground from background. It handles green and blue screens and detects which color is present. GVM and BiRefNet generate alpha automatically, while MatAnyone2 and VideoMaMa provide paint-and-track control. A dual viewer offers source, alpha, or composite views, an A/B wipe, pan and zoom, channel switching, and live despill, refine, and despeckle controls. The queue processes clips in sequence, with progress, sound cues, recent projects, and session saving. Exports include EXR and PNG sequences, ProRes 4444, and VP9 with alpha while preserving bit depth. Footage and project files stay on local disk, without accounts, telemetry, or cloud processing; the app does request an update check from GitHub on launch. It runs on Windows, macOS, and Linux, with Docker instructions for Linux servers or remote GPUs. Apple Silicon Macs from M1 onward are supported, though alpha generators run slower on Mac. The license is CC BY-NC-SA 4.0; donations are optional.

FuzzPuppy Video Background Remover is a free web tool for removing video backgrounds in a browser. It uses AI removal or green-screen chroma key, then exports transparent WebM or MOV files, or MP4 with a replacement color, image, or video background. Processing happens locally in the browser; Fuzz Puppy says video is not uploaded to its servers for processing. MP4 and MOV inputs can be approximately 600 MB, with shorter, lower-resolution clips described as more reliable on modest GPUs. MODNet is the faster AI model, while BEN2 targets more detailed subjects and requires FP16 WebGPU support. AI removal requires WebGPU; green-screen removal does not. The maker lists current desktop Chrome, Edge, or Safari with WebGPU enabled for AI work. Supported mobile browsers process only the first 15 seconds at up to 720p and 24 fps with MODNet or green-screen removal. No signup or watermark is listed, and transparent MOV can be composited in compatible CapCut, Blender, and other alpha-video editors.
