Ultimate Video Speed Control

Speed up or slow down any web video with hotkeys, custom steps, a 1x toggle and a customizable on-video speed badge.

Ultimate Video Speed Control lets you take full control of playback speed on any site that uses HTML5 video or audio — YouTube, Vimeo, Coursera, Udemy, Bilibili, and most embedded players. Features: • Hotkeys, all rebindable — faster / slower by a step you choose, toggle between your current speed and 1x, toggle between a preferred speed (e.g. 2x) and 1x, jump straight back to 1x, and cycle through preset speeds. • Adjustable step size: 0.1, 0.25, 0.5, 1, or any custom value. • On-video badge showing the current speed: always visible, only on mouse move, or hidden — with adjustable size, corner position, opacity and margin. • The current speed is also shown on the toolbar icon and updates live per tab. • Popup menu for quick +/- , a 1x toggle and one-click preset speed buttons. • Remembers your last speed across pages, with an optional "force" mode for sites that try to reset the rate. • Full English and Chinese interface; light, dark or system theme. Privacy: no account, no tracking, no network requests. Every setting is stored locally in your browser.
