NexVid - Real-time Video Upscaler & Enhancer nga Sylphe

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.
- Privacy-friendly processing performed locally in the browser.

Ideal for users who want sharper lines, cleaner details, and more stylized playback without leaving the browser.
