How can you track anyone video YouTube with 4x, 8x or any other custom playback speed you want?
The settings window in the YouTube video player lets you quickly change the default playback speed of your current video. You can get up to 2x the video playback at twice the normal speed. The lower limit is 0,25 which will slow down the video to a quarter of its original speed.
YouTube allows you to play videos at 2x the original speed, but what if you want to speed up and watch videos even faster, say 4x or 10x faster than normal?
Chrome Developer Tools can help there.
Open any YouTube video with Google Chrome and launch the JavaScript console from the menu bar (three dots on the top right) of Chrome. In the Tools menu, select Developer and select console from the submenu.
In the console click on the clear console
In the JavaScript console window, type the following command and it will immediately change the playback speed of the current video to 10x the normal speed. If you do copy – paste and press enter.
$ ('video'). playbackRate = 10;
If you want to slow down the video, try a value less than 1:
$ ('video'). playbackRate = 0.125;
You can set the playback speed to any value between 0,0625 and 16. This is the allowed media playback range in Chrome.
