Lumora

Video enhancer: smoother, sharper streaming video with frame generation, upscaling, compression cleanup and a film look. WebGPU.

Lumora makes online video smoother, sharper and cleaner right inside your browser. It turns 24, 30 or 60 fps video into a fluid picture on a high-refresh screen and sharpens low-resolution streams. Everything runs locally on your graphics card with WebGPU, so your video never leaves your computer. WHAT IT DOES • Frame generation — creates in-between frames so video plays smoothly on 60–240 Hz screens. Modes: Adaptive (follows your screen), 2x, 3x, or Custom with the exact frame rate you type. Motion analysis is about twice as fast as before at the same picture quality, so it leaves more GPU headroom for 1080p and high refresh rates. • Upscaler with three algorithms, chosen from a drop-down with a tip for each: – Edge-aware — fast, smooth scaling that follows edges. Lightest on the GPU. – Crisp edges — sharper lines and fine detail. – Neural AI — neural networks that rebuild detail in low-resolution video (up to 720p sources). Lumora picks the network that fits your graphics card: a light one by default, a wider one where the card has room to spare, and a large one only on very fast cards for small pictures. Flat areas are skipped to save power, and it switches itself off safely when the video or the GPU is too heavy. • Sharpness — one slider for the base crispness. More options (restoration, vibrance, film look, grain) are one click away under "Advanced". • Compression cleanup — reduces blocky artifacts, noise and banding in poor-quality video, and smooths noise between frames on steady scenes without ghosting. • Film look — optional warm color grade and fine film grain. • Auto quality — Lumora watches your graphics card and lowers or raises the processing level so playback stays smooth, or pick Light, Balanced or High yourself. • One-click ✦ Auto — picks settings for your screen and the current video. • Clear status — if nothing is happening, the menu tells you why: no video found, WebGPU unavailable, protected video, a source that does not allow reading its picture, or a graphics card that cannot keep up. A video is only called protected when its picture really cannot be read. • Master switch — turn everything off from the menu header in one tap; opening the menu never turns it back on by itself. • On-screen counter — optional frame rate and GPU time display, with hotkeys you can change (work on any keyboard layout). • Smart video pick — thumbnails, hover previews and mini-players are ignored; only the main player is enhanced. • 10 interface languages — English, 简体中文, हिन्दी, Español, Français, العربية, Português, Русский, Deutsch, 日本語. The language follows your system and can be changed in the menu. HOW TO USE Open any page with an HTML5 video and start playback. A small badge with the Lumora logo appears over the video with a short welcome. Press "✦ Auto" for a one-click setup, or click the badge (or the toolbar icon) to open the settings. Pick an upscaler algorithm and sharpness, or leave Auto quality on. Default hotkeys: Alt+S turns Lumora on or off, Alt+Z shows or hides the counter. You can change both in the menu. REQUIREMENTS A recent Chromium-based browser (Chrome, Edge, Brave) with hardware acceleration on, and a graphics card with WebGPU support. If WebGPU is not available, Lumora stays idle, says so in its menu and does not affect the page. Frame generation and the neural upscaler add GPU load; on weak hardware choose the Light quality level, use Edge-aware scaling, or turn frame generation off. PRIVACY Lumora does not collect, store or send any data. It makes no requests to external servers and loads no remote code. The neural network weights are bundled in the package and read from the extension itself. Only your settings are saved, locally in your browser. NOTES • Video protected by DRM, or video from other origins that the page does not allow to be read, cannot be processed; Lumora skips it safely and shows the original. Lumora does not try to get around such protection. • Results depend on the video and your hardware. Interpolation can show small artifacts on very fast or chaotic motion; lower "Interpolation strength" or the quality level if you notice them. • The Neural AI upscaler uses the ArtCNN models by João Chrisóstomo (MIT license).
