Video Speed Controller Extension

HTML5 video provides native APIs to accelerate playback of any video, but most implemented players either hide or limit this functionality. This extension fixes that, plus more...

It will help you optimize your video viewing by allowing you to make quick playback speed adjustments, as well as rewind the video to hear the last few second one more time. We don't read at a constant speed, and we talk much slower than we read - there is no reason why we have to listen at a constant speed and at a (very) slow rate.

Once the extension is installed simply navigate to any page that offers HTML5 video, and you'll see a speed indicator in top left corner of the video player. Hover over the indicator to reveal the controls to accelerate, slowdown, or rewind the video (10 seconds + lowers playback speed). Or, even better, use your keyboard:

- S - decrease playback speed.
- D - increase playback speed.
- R - reset playback speed.
- Z - rewind video by 10 seconds.
- X - advance video by 10 seconds.
- V - show/hide controller.

If you prefer other shortcuts, want to change the increment value, or want the player to remember your playback speed in the future, head into the settings page and customize it to your heart's content.
