Speed Master - Video Playback 0.25~5x

Play any HTML5 video at 0.25x to 5x speed (step 0.25). Adds extra speed levels into popular sites' native menu. No Premium.

Speed Master is a free, lightweight Chrome extension that gives you precise speed control for any HTML5 video on the web. KEY FEATURES • Speed range: 0.25x ~ 5.00x, in 0.25 steps (20 levels) • Smart injection: Adds extra speed options directly into the native speed menu of popular video sites (no need to open the popup every time) • Universal: Works on YouTube, Bilibili, Vimeo, Twitch, online courses, and any site with HTML5 <video> • Bypass Premium-only speeds: Set 3x, 4x or 5x even on platforms that gate them behind paid plans (extension writes to <video>.playbackRate directly) • Anti-reset: Detects and overrides sites that try to reset your speed after buffering / source switching / autoplay • Keyboard shortcuts: - Alt + Up Speed up by 0.25 - Alt + Down Slow down by 0.25 - Alt + 0 Reset to 1.0x • Mouse wheel on the speed button to fine-tune • Beautiful in-page toast showing the current speed • Only affects the page's main video (won't speed up small auto-preview thumbnails) • No account, no tracking, no data collection — 100% client-side WHY ANOTHER SPEED CONTROLLER? Existing video sites cap their speed at 2x (sometimes locked behind Premium). Speed Master removes that cap, offers a fine-grained 0.25 step, and feels native because it injects right into the site's own speed menu.
