A Tampermonkey script that enhances video playback on any website with convenient keyboard shortcuts and a powerful volume booster (up to 10000%). Skip forward/backward, and amplify quiet videos — perfect for online lectures!

Features

  • ⏪ Rewind: Jump back 10 seconds with the left arrow.
  • ⏩ Fast Forward: Jump ahead 10 seconds with the right arrow.
  • 🔊 Volume Booster: Can amplify video sound up to 10000%.
    • ⬆️ Increase Volume: Use the up arrow to boost volume.
    • ⬇️ Decrease Volume: Use the down arrow to lower volume.
  • 🎛️ Noise Filter: Reduce background noise for clearer audio.
    • Toggle on/off with N key.
    • Adjust noise filter frequency with Ctrl + Up⬆️/Down⬇️ (500Hz - 6000Hz).
  • 🔄 Language Support: Auto-detects browser language (English/Chinese).

Whitelist Setup

To make the script run only on specific websites, modify the @match lines in the script's metadata. For example:

// @match        https://moodle.xxx.edu.tw/*
// @match        https://example.com/*

This ensures the script only activates on those websites.

Usage

  1. Visit any website with an HTML5 video.
  2. Use the keyboard shortcuts to control playback and boost volume.
  3. A visual overlay will appear to confirm actions.

Compatibility

  • Works on most websites with <video> elements.
  • Tested with Moodle and YouTube.
