Ultra-Enhancer: Video Color Grade, HDR 4K, Cinematic, Sharpen

Ultra video enhancer for any web video: HDR 4K color grade, brightness, contrast, sharpen & clarity. Live & reversible.

Ultra Enhancer is a video enhancer for any web video. It applies a cinematic color grade, an HDR-style look, and 4K-level clarity, and gives you live control over brightness, contrast, saturation, and sharpening. Everything happens instantly, runs on your device, and can be undone at any point. It turns dull, dark, or washed-out footage into a punchy, cinematic picture. It works on YouTube, Vimeo, Twitch, and pretty much any site that uses an HTML5 video player. No uploads, no re-encoding, no account to set up. Every adjustment is applied live in your browser, and you can switch it all off whenever you like. ★ ENHANCE ANY VIDEO - Tone-curve color grading with separate Shadows, Midtones (gamma), and Highlights, so you can brighten a dark video without blowing out the bright parts - An HDR-style look that deepens contrast and brings back detail in the darkest and brightest areas - 4K-style clarity from the Sharpen, Clarity, and Denoise controls, for a crisp and clean result - Brightness, contrast, and saturation controls - Hue, sepia, grayscale, invert, and a Bloom control for a soft cinematic glow ★ ONE-TAP READY MODES One click gives you a full look: Movie, Sports, Games, Low Light, High Light, Night, Vivid, Cinema, Warm, Eye Comfort, and B&W. There are also dedicated 1080p, 2K, and 4K modes, each tuned to sharpen and clean up that resolution. ★ 6 SAVED PROFILES Create and keep up to 6 of your own grades. Every change saves on its own, so switching between your day, night, and cinema looks takes a single tap. ★ LIGHT & DARK THEME The popup is clean and simple, and comes in a light or dark theme to match your setup. ★ PRIVATE BY DESIGN Ultra Enhancer collects no data, makes no network requests, and has no sign-in. All grading runs on your device using GPU-accelerated CSS and SVG filters, so it stays smooth and fully reversible. It never changes the original video or the website itself. Use it to grade footage cinematically, get a more HDR-like image, sharpen a soft picture, or make late-night viewing easier on the eyes. It works on any web video you come across.
