EZ-CorridorKey vs VideoBGNinja

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.

VideoBGNinja is a web tool for removing backgrounds from short videos of people without a green screen or account. Its AI matting separates the person frame by frame and follows that subject through the clip. You can upload MP4, MOV, WebM, MKV, AVI, M4V, MPG, MPEG, WMV, or 3GP files. Outputs include transparent WebM, transparent GIF, green-screen MP4, and alpha-matte MP4; paid passes also provide ProRes 4444 MOV with alpha. The free plan costs nothing and handles clips up to 90 seconds, 2 GB, and 1920 px on the longest side. A free e-mail pass offers four minutes, 4 GB, and 2560 px. Paid passes cost €3 as a one-time purchase for 24 hours or €5, paid once for 30 days, raising limits to four minutes, 4 GB, and 3840 px. Processing runs in the Netherlands, with uploads deleted after processing.
