Corridor Key vs FuzzPuppy Video Background Remover

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.

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.
