EZ-CorridorKey vs Picsart Video Background Removal API

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.

Picsart Video Background Removal API removes video backgrounds or replaces them with a custom color or image. It accepts WEBM, MP4, and MOV files up to 500 MB and 1920×1080 resolution. Requests can specify a background color or image URL; transparent output is available but requires WebM. Processing is asynchronous: submit a request, receive a transaction identifier, and use that identifier to retrieve the result. Batch processing is supported. Requests require an API key in the X-Picsart-API-Key header, and accounts can make up to 500 requests per minute before excess calls receive a 429 response. Picsart lists video background removal at 15 credits per minute, with monthly credit pricing tailored to estimated volume and use case. New accounts receive 5 free credits, and a free trial provides full API access without a stated duration. The service is aimed at developers and business workflows such as e-commerce, social media, and digital asset management.
