Change YouTube speed from your favorites bar

Posted on: 23 May. 2018

I feel the need... the need for speed!

Premise

While the UI of YouTube only shows only limited set of high-speed options, it is possible to set the speed to any floating point value. Even better, one can do so from their favorites bar with bookmarklets.

Youtube dialog to set speed   ⇒   Bookmarks to set youtube speed

Method

Simply add any of the following code snippets as bookmarks.

If you have a fixed speed in mind, e.g. 2.5:

javascript:document.getElementsByTagName("video")[0].playbackRate=2.5;

Or save this line to show a prompt that asks for a floating-point input:

javascript:var%20speed=prompt("Speed:","1.");document.getElementsByTagName("video")[0].playbackRate=parseFloat(speed);

Which results in the following prompt:

A prompt that asks for speed

Caveats

Works with YouTube and Vimeo.

The speed display in the video player will remain to show the last setting.
