LumaTune

Tune video appearance, speed, and Theater Mode from the popup or on-video controls.

LumaTune lets you adjust how videos look and play in your browser. Open the Adjust tab to change brightness, contrast, saturation, and playback speed from 0.25x to 8x. Use sliders or numeric inputs, reset controls individually, or temporarily pause adjustments while keeping your saved values. The compact on-video controls follow the selected player and give you quick access to speed and viewing actions. Theater Mode fits the player inside the browser window while keeping the browser controls visible. Press Esc to exit Theater Mode. Native Picture-in-Picture opens one video in a floating window when the browser and player support it. Visual filters may be unavailable in that window. Open Video info to see the video's resolution and playback status. Enable it per site to view optional details such as buffering and lost frames. Video info shows observations from your browser and leaves the player in control of playback. Preview built-in presets by hovering over them or focusing them with the keyboard. Apply a preset for the current site or use Undo to restore the previous settings. Use the Site profiles page to search, edit, disable or delete your saved site preferences.
