I often set the playback-rate of youtube videos to something like 1.25 or 1.5 to get through a video a little faster without getting bored.

But sometimes 1.25 is a little to fast for my taste.

So i just went and had a look into the html and found that i can easily get any playback speed i want by running this snippet:

document.getElementsByClassName('video-stream html5-main-video')[0].playbackRate=1.125;

This sets the speed to 1.125. But any rate will do: 0.69, 4.20, 6.666. Doesn’t matter.

It’s kinda obvious that it will throw an error if there is not at least one element on the page with the classnames ‘video-stream html5-main-video’, but nevermind.

I then added this snippet into a browser-bookmark i can click anytime i’m watching a yt video and want to set the speed.

javascript:{document.getElementsByClassName('video-stream html5-main-video')[0].playbackRate=1.125;}

PSA, do not copy any JS code on the web to your browser unless you understand it or it has been validated by many others.

in general, well-established browser extension are unlikely to be malicious, but random JS code on the internet can.

(in this specific case, the code seems fine to me.

I was actually surprised that you could still bookmark javascript: URLs since you can’t paste them into the address bar anymore.

Doesnt youtube have a playback speed option built into the player?

Sorry, I get it. This allows any playback speed whereas youtube has specific options

Yes, but it goes in steps of 0.25 and that sometimes is too coarse/rough.

E.g. 0.50, 0.75, 1.00, 1.25, 1.5

This snippet is just to get a little more fine-grained control.

I think what they’re trying to tell you is that you can have ANY playback speed instead of the 4 options given by the built in player.

If you replace the speed number with Number(prompt(“New speed:”, 1.15)) you should get a dialog box to put a new speed in, so you don’t have to make multiple bookmarks.

BTW, glad to see bookmarklets still living. If I wasn’t wrong, Firefox seems to be the only browser supporting it.

Chromium browsers still support bookmarklets

I use Enhancer for YouTube. It uses step increments of .1 plus has a ton of other features like being able to take a screenshot of the video.
