How to Speed Up or Slow Down YouTube Videos
You can easily speed up YouTube videos or slow down video playback, all by adjusting some simple but largely hidden and little known settings on the YouTube web site. This is a helpful trick for many reasons, for example if you’re watching something boring that you want to accelerate, if you want to speed up a conversation or interview you’re watching, or maybe you want to slow down a video to enjoy it at a more casual pace or to understand it better.
You can also use this trick to speed up and slow down songs played on YouTube. All you need is a web browser, and it works the same on any computer.
