Features & Capabilities

Video Speed Controller MV3 is a powerful Chrome extension designed to give you full control over HTML5 audio and video playback. By integrating intuitive keyboard shortcuts, this tool allows users to speed up, slow down, rewind, and advance video content effortlessly. Unlike typical video players that restrict playback speed options, this extension provides flexibility to optimize how you watch videos, accommodating different reading and listening speeds.

After installation, users will notice a speed indicator on HTML5 video players, offering direct access to playback controls. Keyboard shortcuts like 'S' and 'D' adjust the speed, 'Z' and 'X' rewind or advance by 10 seconds, and 'R' resets the speed to normal. The extension supports customization in its settings, enabling users to modify shortcuts, adjust speed increments, and save preferred playback speeds. Updated to Manifest V3, it also provides enhanced privacy by allowing users to disable access on all websites if desired.

The controls should be at the bottom with other controls, not overlying the video.
