Help:How to speed up a Facebook video
In google chrome, simply:
Press command + option + j on Mac (ctrl + shift + j on PC). This will open chrome dev tools
In the window that just opened up, find the ‘Console’ tab and click on it
Find the little flashing text cursor where you can type things. Hint: it’s to the immediate right of the > symbol
Paste this code in and hit enter
videos = document.getElementsByTagName("video");
for(var i = 0; i < videos.length; i++){
videos[i].playbackRate = 2;
}
This will change the speed to double speed, but you can edit the 2 on the second last line to 0.5 for half speed, or to 3 for triple speed.
You can use fractions as part of the playback rate (e.g. 1.75)
In general speeds above 1.75 are difficult to follow
Caveats
Note that if you skip ahead or back in the video, you will need to reapply the code in order to speed the video back up.
