NexVid - Real-time Video Upscaler & Enhancer — 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 - works great even on less powerful computers thanks to adjustable filters and profiles.
• 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, Russian, and Simplified Chinese.
• Privacy-friendly processing performed locally in the browser. 🔒
• Upscale and Export a video from your local computer

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

Our extension provides occasional, non-invasive ads within the extension interface, including in the popup and/or other internal extension pages to keep the service free for our users.
