BGRemove.video vs EZ-CorridorKey

BGRemove.video is a free web service that removes video backgrounds and exports transparent clips with an alpha channel. It accepts MP4, MOV, WebM, M4V, and GIF uploads up to 60 seconds and 2 GB. Its AI follows subjects across frames to reduce flicker and keep edges stable during movement. Transparent output is WebM using VP9 alpha, with the source dimensions preserved. You can place a solid color, blur, image, or video behind a processed clip and export an MP4 without consuming another removal allowance. The free plan costs nothing and allows three successful removals per 24-hour window, with no watermark. Files are processed in the EU and retained for 24 hours, or deleted sooner when requested. Google is the only sign-in option. The maker says uploads are not used to train its models or its provider’s models. Manual edge refinement is unavailable, and glass, smoke, fine mesh, depth-swapping overlaps, and severely underexposed footage are difficult cases.

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.
