Video Speed Controller Plus

About

Video Speed Controller Plus is a fork of the popular Video Speed Controller. It keeps the familiar keyboard-driven workflow for HTML5 video and audio while adding richer customization and localization.

Core features
• Change playback speed with keyboard shortcuts (S/D to slow down / speed up, R to reset, and more)
• Optional on-screen controller overlay on HTML5 video and audio
• Frame stepping and time seek shortcuts (customizable in Options)
• Remember playback speed across videos (optional)
• Exclusive keyboard shortcuts option to reduce conflicts with site hotkeys

Plus extras
• Customize controller colors, opacity, border, button size, and variable-font weight/width
• Live preview in Options → Advanced → Appearance
• Popup and full options page with light/dark/system theme and accent color
• English, Japanese, and Simplified Chinese UI

Works on most sites that use standard HTML5 <video> and <audio> elements. Google Meet and Hangouts are excluded by default.
