IMGLAB Video Speed Control

About

IMGLAB Video Speed Control — watch smarter, not slower.
Control playback speed on any website with a clean on-page overlay, 
fully remappable keyboard shortcuts, per-site speed memory that 
remembers your preference for every site you visit, and a smart 
block list to skip sites where speed control doesn't belong.

 CORE FEATURES
─────────────────────────────────
⚡ On-Page Speed Overlay
A minimal floating controller appears on every video:
[ − ] [ 1.50 ] [ + ] [ × ]
Drag it anywhere. Double-click the speed number to instantly toggle 
between 1× and your preferred speed. No mouse wheel accidents.
🧠 Per-Site Speed Memory
Each website remembers the last speed you used. YouTube at 1.75×, 
lecture sites at 2×, movies at 1×. Switch sites and your speed 
switches with you — automatically.
⌨️ Keyboard Shortcuts — All Remappable
Speed up, slow down, reset, jump to preferred speed, or cycle through 
your favourites — all from the keyboard. Every key can be reassigned 
from the popup. Default shortcuts:
  X — Decrease speed
  C — Increase speed
  Z — Reset to 1×
  V — Jump to preferred speed
  B — Cycle through favourite speeds
  H — Show / hide overlay
🔁 Cycle Mode
Set up your favourite speeds (e.g. 1.25× → 1.5× → 1.75×) and tap B 
to rotate through them instantly.
🎞️ Frame-by-Frame Stepping
Pause any video and step through it one frame at a time using , and . 
Perfect for analysing footage, catching a moment, or reviewing a move.
🚫 Block List
Some sites use custom video pipelines incompatible with speed control 
(TikTok is a known example). The built-in block list lets you exclude 
any site with one click — the extension simply stays out of the way. 
Popular sites are suggested, or add your own custom domains anytime.
🎛️ Fully Configurable
Open the popup to set your preferred speed, step size, min/max limits, 
cycle speeds list, and controller opacity. Everything is saved and 
synced across your Chrome browsers.

 YOUTUBE — PLAYS NICE
─────────────────────────────────
On YouTube, the extension is smart enough to stay out of the way. 
Space, arrow keys, comma, and period are left entirely to YouTube's 
own handlers — so seek animations, progress bar updates, and keyboard 
UI all work exactly as YouTube intended. The extension only manages 
speed keys on YouTube.
YouTube's single-page navigation is fully supported: the overlay and 
speed settings follow you from video to video without a page reload.

 PRIVACY
─────────────────────────────────
We collect absolutely nothing. No analytics, no tracking, no servers. 
Your settings are stored locally on your device using Chrome's built-in 
storage. Full privacy policy at imglab.net.
