Question

My question is that how can we increase speed of YóuTube videos by more than 2x using JavaScript?

Answer 1

Steps to increase speed of video by JavaScript:

Step-1:-

Firstly press ctrl+shift+J

Then a window will appear in front of you as shown in the attachment.

Step-2 :-

Paste the following JavaScript programme in console window.

document.getElementsByTagName("video")[0].playbackRate = x

Your video speed is now increased.

Step-3 :-

Again press ctrl+shift+J for closing that mini window.

Remember that:

• In step 2, you have to replace x with the Speed you want.

Such that if you want 3x speed replace x with 3.

• You have to always perform these steps while changing video. Even you are playing any playlist, each video requires these steps.

• Speed over 16x will not have any sound.

• Paste correct JavaScript programme.
