Video Speed Controller (Wheel + Keyboard)
Extension Actions
Lightweight and efficient video speed adjustment tool, supports mouse wheel/keyboard shortcuts, multi-platform personalized configuration and speed memory
Adjust playback speed quickly on major video platforms via mouse wheel or keyboard shortcuts, with support for platform-specific custom configurations and speed memory.
I. Core Features
Mouse Wheel Quick Adjustment
Hover the mouse over the video speed display area (1.0X) – the mouse pointer will change. Scroll up/down to fine-tune the playback speed.
Precise Keyboard Control
Win + Alt + ↑/↓: Simulate wheel adjustment for precise speed increments/decrements.
Win + Alt + [Number]: Directly set a specific speed (e.g., Win + Alt + 1.5 to switch instantly to 1.5×).
II. Multi-Platform Support
Full mouse wheel support: Bilibili, Xiaohongshu, Douyin, Kuaishou, and YouTube (landscape mode).
Keyboard-only support: All other video websites.
Supported domains:
bilibili.com, xiaohongshu.com, douyin.com, kuaishou.com, youtube.com
Custom Configuration
Independent settings for each platform, including:
Adjustment step size
Minimum/maximum speed limits
Option to remember last playback speed
Speed Memory
Automatically saves the last playback speed for each platform. The saved speed is restored automatically when opening a new video, eliminating repeated adjustments.
III. Usage Scenarios
Skip redundant content quickly when studying online courses or educational videos.
Flexibly adjust playback rhythm for short videos and TV shows.
Avoid repeatedly opening the speed menu and control playback more efficiently.
IV. Notes
Due to official restrictions on Douyin, the maximum speed is capped at 3.0× and cannot be overridden by configuration.
The DOM structure of some platforms may change with updates. If features stop working, check for extension updates.
The extension only injects scripts on video pages and does not collect any personal data – safe and reliable.
