Video Speed And Volume With Mouse Wheel gives you precise mouse-wheel control over video and audio players directly from the webpage.

Instead of constantly moving your mouse to find player controls, assign different functions to different areas of a video and control them instantly with the mouse wheel and mouse buttons.

🎛 Video & Audio Controls

Control the following functions with your mouse wheel:

🔊 Volume
⏩ Playback Speed
⏭ Seek / Fast Forward / Rewind
🔆 Brightness
🌓 Contrast
🔆🌓 Brightness + Contrast
🎨 Grayscale
🟤 Sepia
🌈 Saturation
🎨 Hue Rotation
🔄 Invert
🌫 Opacity
💨 Blur
🔃 Flip / Rotate
🔁 Repeat a selected section
⛶ Fullscreen
🛑 Block page scrolling
None — leave an area inactive
🖱 Mouse Wheel + Mouse Buttons

You can configure different behavior for:

Mouse wheel alone
Left mouse button + wheel
Right mouse button + wheel
Middle mouse button + wheel

Each direction can have its own configurable value or action.

For example, you can configure:

Wheel Up → Increase volume
Wheel Down → Decrease volume

or use different mouse buttons to create additional controls.

🗺 Custom Video Control Areas

Divide the video into multiple regions and assign a different function to each region.

For example:

Top-left → Playback Speed
Top-right → Volume
Bottom-left → Brightness
Bottom-right → Seek

The number of regions can be customized, allowing you to build a control layout that fits your workflow.

🔆 Brightness + Contrast Mix

The extension includes a combined Brightness + Contrast control.

Both values can be adjusted together while using a dedicated visual overlay icon and a clean numeric value display.

The mix control also returns correctly to its neutral 1.00 state without displaying NaN.

🎯 Region Boundary Markers

When using divided video areas, optional visual boundary markers show where each control region is located.

Customize:

Marker visibility
Marker size
Marker display duration
Marker style
Built-in marker images
Your own custom marker image
📊 On-Screen Value Indicators

Display the current value directly over the video while adjusting a setting.

You can configure:

Whether values are displayed
Display duration
Indicator appearance/style
Function-type indicators

This makes it easy to see changes without opening the video player's controls.

⚡ Playback Speed Control

Change playback speed smoothly with the mouse wheel.

The extension also provides a Force Playback Speed option for pages that attempt to prevent normal playback-speed changes.

🔊 Volume Boost

In addition to normal volume control, volume gain can be configured for additional amplification.

🔁 Repeat Sections

Create a repeat segment directly with the mouse wheel:

Set the beginning of the section
Set the end of the section
Enable/disable repeat
Move the video to the repeat segment boundaries

Useful for repeatedly studying, practicing, or reviewing a specific part of a video.

🔃 Flip & Rotate Video

Use mouse-wheel controls to:

Flip horizontally
Flip vertically
Rotate 90° clockwise
Rotate 90° counterclockwise
⚙ Highly Configurable

Almost every adjustment can be customized, including:

Step size
Mouse-button behavior
Wheel direction
Seek duration
Playback-speed increments
Volume increments
Brightness/contrast increments
Filter increments
Overlay display time
Region layout
Marker appearance
🌐 Site-Specific Operation

Choose which websites the extension operates on by registering sites in the options page.

This lets you keep the extension disabled on websites where you don't need mouse-wheel video controls.

⏸ Optional Pause Behavior

You can configure the extension to disable its controls when the video is not playing.

🔘 Browser Action Button

The browser toolbar button provides quick access to the extension.

You can:

Enable/disable the extension on the active page
Restore the active page's playback speed and visual effects to their default values using the middle mouse button
💾 Customizable Video & Audio Player Controls

The extension supports both video and audio player areas, allowing you to configure controls according to the type of media you're using.

Make your mouse wheel a complete media-control system.
Control your media without constantly reaching for on-screen player buttons.
