Global Speed

Universal speed control for video and audio.

This is a fork of polywock/globalSpeed with an added Time Info overlay feature (see below). The store links below point to the official upstream release, which does not include this feature — to use it, build this fork yourself (see Build).

Install the Edge, Firefox, or Chrome extension.

Speed Control

• Set the speed once and forget: it automatically applies to all video and audio
• Define URL rules to auto-apply your favorite speeds on specific sites
• Compatible with YouTube, Netflix, Spotify, podcast sites, and more

Media Hotkeys

• Conveniently change speed through customizable shortcuts
• Rewind/forward, frame-by-frame analysis, volume up/down and more
• Support for multiple trigger modes, including context menu and global shortcuts; control background music or PiP videos while using another app

Filters & Effects

• Netflix movie too dark? Brighten it and dial in the contrast
• Video too quiet? Boost volume up to 600%
• Listen to songs or shows in a new way with pitch shift
• Optionally assign hotkeys to toggle filters and effects on the fly

Time Info (this fork only)

• Shows current/total time and the wall-clock time the video will finish, scaled to playback speed (e.g. at 2x, remaining time and finish time are both adjusted accordingly)
• Place it pinned to a screen corner (most stable) or anchored to the video frame
• Optional remaining-time countdown, 12/24-hour clock format, and a custom text format using {{time}}, {{clock}}, {{remaining}}
• Auto-hides on mouse hover so it never blocks native player controls
• Colors default to the extension's theme, fully customizable otherwise
