Overview
Product summary
Review the store description, core capabilities, and common use cases.
Use to control speed on HTML5 video and audio streams.
Can add SRT files as WEBVTT tracks, style the subtitles and set the delay so that they are in sync (tip: use the console log to help you) (Press the underscore button on the UI to start/complete the process of adding subtitles).
This extension is safe to use in incognito mode as the only data it stores is the settings; I recommend enabling it for file URLs.
You can add a colour matrix and other video CSS, but there is one enabled by default that makes greens and pinks more realistic.
Changelog:
15/10/2023: Picture-in-Picture button added to bar; more efficient code used to search for streams.

da best
great extension, one of the only ones that has the feature i was looking for - speed adjustments using the mousewheel without clicking or using the keyboard. the only feature missing now to make this the perfect speed extension is setting a default speed
Absolutely Excellent! Please add simple documentation.
Didn't Work.
The visuals are not great, but this is SO COOL! Huge work, working very good !!!
Has Everything a video controller should!
Amazing work! Agree with a previous review that keybinding and switching speeds with immediately reachable button (as opposed to pop-up slider) make work so much faster than other similar extensions.Thank you!
It WORKS AMAZING!!! I really like the 'keybinding' options- It just makes things even faster. Thanks for your Amazing work. I can see that you keep working on Updates and fixing bugs, Really Appreciated!!
