Cinema Glow – Lights Off + Ambilight

Dim everything except the video and surround it with a real-time Ambilight glow that follows the colors on screen.

Turn any web page into a home theater. Cinema Glow dims everything around the video you're watching and surrounds the player with a soft ambient glow that follows the colors on screen in real time, like a Philips Ambilight TV. ★ FEATURES • One-click cinema mode: dims the whole page so only the video stays bright • Real-time Ambilight: the glow follows the colors at each edge of the video (top, bottom, left, right) • Works on YouTube, Vimeo, embedded players, and most HTML5 video sites • Adjustable darkness, glow intensity, and color smoothness • Keyboard shortcut: Alt+Shift+L (you can change it) • Press Esc or click the dark area to turn the lights back on • Smooth fade animations, and it respects your system's reduced-motion setting ★ HOW TO USE 1. Open any page with a video 2. Click the Cinema Glow icon, or press Alt+Shift+L 3. Enjoy the show. Press Esc to turn the lights back on ★ LIGHTWEIGHT Cinema Glow does nothing until you turn it on. While it's active, it reads a tiny 48×27 pixel version of the video frame about 15 times a second, so it barely uses any CPU. ★ 100% PRIVATE • No data collection • No tracking or analytics • No network requests • Everything happens on your device Note: Some sites block access to their video's colors. On those sites, Cinema Glow shows a soft static glow instead. Chrome doesn't allow extensions on internal pages such as chrome:// or the Chrome Web Store.
