Increase playback speed on any video

speedup.md

document.querySelector('video').playbackRate = 1.5

• Videos on any page using a video tag. Youtube, vimeo etc

• (Right click/2 finger click on mac -> inspect element); on the video to reveal the <video></video> tag, otherwise you might get a var v = document.querySelector('video'); var t = prompt('Set the playback rate'); v.playbackRate = parseFloat(t) err.

• Paste this into the console (go to console from the window that pops up from inspect element or cmd + option + i):

var v = document.querySelector('video'); 
var t = prompt('Set the playback rate'); 
v.playbackRate = parseFloat(t)

• Enter a speed, e.g. 1.5 for 1.5x or 2 for 2x and enjoy.

For places like FB with many video tags use this (will work everywhere):

document.querySelectorAll('video').forEach(v => v.playbackRate=2)

btw the upper limit for Youtube seems to be 16x
