BGRemove.video vs Knockout API

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.

Knockout API provides image and video processing through a browser app and API. Its image tools cover background removal and replacement, batch processing, masking, smart crop, stickers, outlines, shadows, and inpainting; the API also handles upscaling, portrait restoration, colorization, and object removal. Video background removal runs asynchronously, with job polling for progress. The browser Canvas supports layered designs with text and effects, and users can save canvases and cutouts to a free account. Developers can connect through REST, any HTTP client, or official Node, React, Python, and CLI options. The service says it manages GPU processing, endpoint updates, usage records, credentials, teams, and billing. Its privacy policy says uploaded images are processed in GPU worker memory, not retained after the response, and not used to train models. The Free plan is free, with 30 images per month and 60 requests per minute. Pay-as-you-go is $0.02 a month, with metered usage billed monthly; Plus is $10 a month. Paid tiers have no monthly cap and a 600-request-per-minute limit.
