# VideoBGRemover — AI Video Background Remover, Video Blur, Green Screen Keyer & Alpha Inspector > VideoBGRemover is a unified online video background and privacy processing suite combining two cloud AI engines (VideoBGRemover for green-screen-free background removal & replacement, and VideoBGBlur for multi-frame face, license plate, screen, and custom object redaction) with two 100% free browser-local WebGL2/WASM tools (VideoBGChroma for green/blue screen chroma keying and VideoBGAlpha for transparent video alpha channel inspection). ## Core Capabilities & Verified Technical Specs - **Cloud AI Video Background Remover (`/`)**: Remove or replace video backgrounds without a green screen using automatic subject segmentation or SAM3 natural-language prompts (`person`, `product`, `dog`). Run a 3-second preview first (3 credits). Cached segmentation masks allow 0-credit background replacements (transparent, solid hex color, custom image, or video backdrop) for 7 days. Exports: Transparent WebM (VP9 alpha), Composed H.264 MP4 (preserves original audio), and Transparent PNG Sequence ZIP. - **Cloud AI Video Blur (`/blur-video`)**: Automatically detect, track, and blur faces (`target=faces`), license plates (`target=plates`), screens (`target=screens`), backgrounds (`target=background`), or custom text-prompted objects. Adjust Gaussian or Box blur intensity and edge feathering for 0 additional credits once the mask is cached. Automatic 100% credit refund if zero matching targets are detected. - **Free Browser-Local Chroma Keyer (`/green-screen-video`)**: 100% browser-local WebGL2 + FFmpeg WASM chroma keyer for green screen (`preset=green`), blue screen (`preset=blue`), or custom eyedropper colors. Zero server uploads, no account required, 0 credits. Exports Transparent WebM, Lossless MOV, and Transparent PNG Sequence ZIP. - **Free Browser-Local Transparent Video Inspector (`/test-transparent-video`)**: 100% browser-local diagnostic tool verifying both container alpha metadata tags (`alpha_mode=1`, codec pixel format) and decoded RGBA pixel transparency (`alpha < 255`) across 16-frame sampled or 900-frame full scans. ## Credit Formula & Pay-As-You-Go Pricing - **Free Local Tools**: `/green-screen-video` and `/test-transparent-video` are 100% free (0 credits, no login). - **Cloud AI Credit Formula**: Automatic cutout, text cutout, and single-target blur cost 1 credit per billed second (`max(3, ceil(seconds))`). Faces plus license plates cost 2 credits per second. Screen blur is a flat 1 credit. Resolution does not change the price. About $4 per minute. Cloud jobs are limited to about 60 seconds. - **3-Second Preview First**: 3 credits for automatic cutout or single-target blur, 6 credits for faces plus plates, and 1 credit for screen blur. - **Pay-As-You-Go Credit Packs** (never expire, no recurring subscription): Starter 100 Credits ($6.90), Pro 300 Credits ($19.90), Studio 600 Credits ($39.90), Business 1,500 Credits ($99). ## Primary Pages (English & Chinese `/zh`) - [AI Video Background Remover (Home)](https://videobgremover.pro/): Cloud AI video background remover & changer without green screen - [AI Video Blur Tool](https://videobgremover.pro/blur-video): Blur faces, license plates, screens, backgrounds, or custom objects in video - [Free Online Green & Blue Screen Remover](https://videobgremover.pro/green-screen-video): 100% browser-local WebGL2 chroma keyer - [Free Transparent Video Alpha Inspector](https://videobgremover.pro/test-transparent-video): Browser-local container metadata + RGBA pixel alpha checker - [All Video Tools Directory](https://videobgremover.pro/tools): Unified directory of core engines and preset workflows - [Pricing & Credit Rules](https://videobgremover.pro/pricing): One-time credit packs at about $4 per minute.
