Spec score 7.8 #15 of 24 in Video Background Removal Software

What it is

Corridor Key is a free browser-based AI green-screen keyer that removes a video background and replaces it with a solid color, still image, or video. It accepts standard MP4 clips and returns re-encoded H.264 MP4 files. The service says its AI preserves details including flyaway hair, fur, glass, eyewear, and sheer fabric. Fast Mode processes an eight-second clip in seconds; Full Mode takes longer for sharper edge detail. No account or installation is required, and the free plan has no daily or monthly usage cap, although each clip can be up to eight seconds. It runs in desktop, tablet, and mobile browsers, with processing on its servers. Uploaded clips are sent to a Hugging Face Space running BiRefNet. Corridor Key says it does not store clips or outputs on its own servers; Hugging Face terms apply while files are there. HTTPS protects transmission. Availability can depend on Space downtime or GPU queues, and quality varies with edges, motion, lighting, and source quality.
