If you’re anything like me and come across talks on YouTube that are hours long on a regular basis, speeding up playback is a great way to get through them faster and have greater focus.
I like to watch videos at 1.5x speed, which is slow enough so I can still understand (usually), but fast enough so my mind can’t get distracted.
Enabling variable speed control on YouTube requires you to enter their beta HTML5 player trial, which you can find here. Keep in mind that your browser will need to meet certain requirements, and the video player may feel slightly different after you enable it.
After you’ve signed up for the HTML5 trial, clicking the little gear button on basically any video will bring up a selection of choices for playback. You can choose to play videos faster or slower.
Surprisingly, I found that when I started listening to talks at 1.5x speed, I ended up comprehending more of the talk than I did at slower speeds. I’m no cognitive expert, but it seems that playing the video faster causes me to pay much more attention.
