Universal Video Image Control

A lightweight userscript that adds a video adjustment control panel to any website. Unlike many browser extensions that require paid subscriptions, have limited trials, or include tracking bloat, this script is completely free, lightweight, and open.

Features

  • Top-Right Overlay: Adds a small icon to the top-right corner of the screen to toggle the panel over the video layout. Only visible when the mouse moves and hides after 3 seconds.
  • Per-Site Memory: Automatically remembers and applies your custom configurations for each specific domain.
  • Visual Adjustments: Live sliders for Gamma, Brightness, Contrast, and Saturation.
  • State Indicator: A master "Active" switch that grays out the UI when disabled, making it clear when filters are bypassed.
  • Iframe Sync: Safely synchronizes video adjustments across embedded cross-origin players.
