Velocity — Pro-Grade Video Speed Controller

Velocity is a pro-grade, ultra-lightweight video speed controller designed to work on the hardest-to-reach videos on the web.

Unlike standard video speed extensions that break on modern websites, Velocity is engineered with a custom Shadow-DOM piercing engine. This means it instantly detects and commands embedded videos on highly complex sites like Reddit, Twitter, and Udemy, leaving no player behind.

Whether you want to slow a tutorial down to a micro-crawl or blast through a lecture at 5x speed, Velocity gives you absolute, zero-lag control.



Core Features

• ** Universal Detection:** Actively pierces iframes and Shadow Roots to find and control hidden video elements that other extensions miss.
• ** Extreme Velocity (0x – 100x):** Break past the standard 2x limit. Watch content at blistering speeds or slow it down to a frame-by-frame pace.
• ** Audio Pitch Bypass:** Most browsers suffer from horrific robotic audio stuttering when you push a video past 3.0x speed. Velocity allows you to toggle native Pitch Preservation OFF, eliminating the digital stutter so you can clearly comprehend every syllable at massive speeds.
• ** Smart, Unintrusive UI:* A minimalist, dark-mode overlay tracks automatically to the active video. Hover to click, or use the dedicated keyboard shortcuts (Numpad +, -, and ) to adjust the pace without ever opening a menu.
• ** Pro-Grade Performance:** Built with pure vanilla JavaScript and zero external trackers. Velocity uses a highly optimized caching engine to guarantee zero CPU lag and smooth scrolling, even on heavy websites.

Privacy First

Velocity does not track you, does not harvest your data, and contains absolutely zero network analytics. Your settings stay entirely on your local machine.
