You might enjoy the Video Speed Controller Chrome extension.
Get it here.
I use it when I’m trying to find the good part of a video: tap “Jump 10 seconds forward” or “jump 10 seconds back” a few times! Or when Hulu forces me to watch ads, I fast forward through them at 16x speed. And of course, when I’m watching a boring video, I’ll turn up the speed so I can “watch faster”. I’ll turn it to 1.2x speed when I’m trying to watch a slow drama that needs to kick it up, or 2.5x speed for poorly cut Youtube videos!
