Control HTML Video Playback Speed with the Console
My university online class videos don’t have a playback speed option. This is doubly a bummer because the professor talks slowly, and I usually listen to podcasts at 2x speed. Between that and I don’t have time to watch 4 hours of lecture a week at regular 1x speed, I needed a way to speed up the video. With no playback speed controls built into the UI, I thought I was sunk.
I popped open an Inspect window, did some digging into the HTML to make sure I could do what I wanted to do, and then switched over to the Console. It only took two lines:
video = document.querySelector("video") video.playbackRate = 2
