Zovo Speed - Video Speed Controller

Speed up or slow down HTML5 video and audio with shortcuts. Per-site speed memory, pitch correction, skip-silence and A-B loop.

Zovo Speed lets you control the playback speed of any HTML5 video on the web with keyboard shortcuts, so lectures, tutorials and long talks take a fraction of the time, and slow moments can be studied frame by frame. Most sites cap you at a few preset speeds, or offer none at all. Zovo Speed adds precise, always-available control to every video player, on every site. What you get - Speed up or slow down any HTML5 video in fine steps, from 0.1x to 16x. - Keyboard shortcuts to change speed, rewind, advance and reset, without touching the mouse. - A small on-video indicator that shows the current speed and fades out of the way. - Remembered speed per site, so your preferred pace comes back automatically. - Works on YouTube, Vimeo, course platforms, news sites and any page with an HTML5 player. - Optional audio pitch preservation, so faster speech still sounds natural. How it works Open any page with a video and press the shortcut to step the speed up or down. The indicator shows your current rate, and Zovo Speed remembers it for that site. Customise every shortcut in the options page, and set a default speed to start from. Privacy first Zovo Speed runs entirely in your browser and only touches the video element on the page you are watching. It does not track your viewing, does not create an account, and keeps your settings on your device. Free to use, with an optional Pro upgrade for per-site profiles, sync across devices and advanced controls. Everyday speed control is free. Install Zovo Speed and watch every video at the pace that suits you. About Zovo Zovo builds fast, private, single-purpose browser tools that respect your data and your time. Every Zovo extension is local-first, free to start, and carries no ads inside the extension itself. Your settings and content stay on your device, and you can export or remove them at any time.
