Video Enhance - Perceptual Quality Boost Edge extension security report

Perceptual Video Enhancer applies lightweight, real-time visual post-processing to HTML5 video playback in order to reduce visible artifacts caused by aggressive compression. The extension focuses on perceptual improvements such as smoothing color banding, reducing block artifacts, and applying optional gentle sharpening when appropriate. Processing is adaptive and designed to avoid over-enhancing content. Features: • Adaptive debanding using dithering techniques • Edge-aware smoothing for block artifacts • Optional contrast-adaptive sharpening • Presets for Clean, Low-Bitrate Repair, and Anime content • Lightweight WebGL processing with minimal performance impact DRM Compatibility: This extension does not interact with DRM-protected video. If a video element cannot be accessed by the browser, processing is automatically disabled to avoid playback issues. Limitations: • Does not re-encode video streams • Does not restore detail lost to compression • Does not enable HDR • Effectiveness depends on source quality All processing is performed locally in the browser. No personal data is collected, stored, or transmitted.
