About Video Speed Controller

Video Speed Controller is an open source browser extension for Google Chrome that adjusts playback speed for HTML5 video and audio elements on websites. The homepage describes it as working on any site that uses HTML5 media, with examples including YouTube, Netflix, Coursera, podcasts, and local files. It lets users set speeds from 0.07x to 16x in configurable increments.

Users can set a default speed for specific domains, disable the controller on selected sites, and optionally keep the last speed across sessions and tabs. The extension can reapply a chosen speed when a site's player tries to reset it. Keyboard shortcuts can be fully remapped in the settings page. The source is released under the MIT License.
