- Click to Install
A new tab will open. Click the "Install" button.

📚 Usage Guide & Tutorial

This guide will walk you through how to use the script effectively.

Getting Started

Once installed, the script works automatically. Simply navigate to any webpage containing an HTML5 video. To activate the controls, hover your mouse cursor over the video player. All controls are activated by keyboard shortcuts.

Most actions (like changing speed or volume) will show a small, temporary confirmation message on the screen, so you know your command has been received.

Common Scenarios

Here are a few examples of how you might use the script in real situations:

Scenario 1: Watching a Lecture or Tutorial

You're watching a long online course. The speaker is a bit slow, and you want to speed things up. You also need to occasionally jump back to review a concept.

Increase speed: Press the C key repeatedly until you find a comfortable speed (e.g., 1.5x). The current speed will be displayed on screen.
Too fast?: Press the X key to slow it down.
Reset speed: Press the Z key to instantly return to the normal 1.0x speed.
Jump back: Press the ← key to go back 5 seconds. For a bigger jump, press Ctrl + ← to go back 30 seconds.

Scenario 2: Fixing a Dark or Quiet Video

You're trying to watch a video that was recorded in low light, and the audio is very quiet.

Increase Brightness: Press the W key. The video will become brighter. If it's still too dark, press it again.
Adjust Contrast: If the image looks washed out after increasing brightness, press R to increase the contrast.
Boost Volume: Press the ↑ key to increase the volume. You can go past the website's 100% limit, up to 200%.

Scenario 3: Multitasking or Immersive Viewing

You want to keep an eye on a video while working in another window, or you want to get rid of all browser distractions.

Picture-in-Picture (PiP): Press Shift + P. The video will pop out into a small, floating window that stays on top of all your other applications. You can drag it anywhere on the screen.
Web Fullscreen: Press Shift + Enter. This makes the video fill the entire browser window, hiding other parts of the webpage.
True Fullscreen: Press Enter. This makes the video fill your entire monitor.
