  NexVid is a lightweight browser extension for real-time video upscaling and creative enhancement. It uses GPU-accelerated Anime4K processing, advanced filters, and a large library of WebGL shaders to improve anime, cartoons, movies, music videos, and other web video directly in your browser. Choose from 15+ Anime4K upscaling quality profiles, tune the target FPS for your hardware, set a resolution threshold to avoid processing already high-resolution sources, and build your own enhancement stack without uploading media anywhere.
  
  Features:
  - Real-time upscaling with profiles ranging from fastest to maximum quality.
  - Performance controls including target FPS tuning and automatic resolution threshold handling.
  - 30+ WebGL shaders across retro, glow, glitch, chromatic, artistic, anime-focused, and experimental super-resolution categories.
  - Advanced filters and image controls including brightness, saturation, contrast, grayscale, sepia, hue rotation, blur, gamma, emboss, morphology, unsharp mask, and high-pass sharpening.
  - Adjustable shader parameters plus preset saving and loading for complete effect chains.
  - Built-in local video player to apply upscaling, filters, and shaders to local video files.
  - Interface available in English, French, Spanish, and Simplified Chinese.
  - Processing performed locally in the browser.
  
  Ideal for users who want sharper lines, cleaner details, and more stylized playback without leaving the browser.
  
  Our extension provides ads within the extension interface, including in the popup and/or other internal extension pages to keep the service free for our users.
