Speeding Up (or Slowing Down) Lecture Playback

Posted by Brian Klaas at 10:02 AM Online Courses

One of the advantages of video-based lectures in online courses is that the videos can be sped up or slowed down as needed during playback. The video player used in online courses here at the School has had this capability since May 2013. 

To speed up video playback, press SHIFT + the right arrow key at the same time.

To slow down video playback, press SHIFT + the left arrow key at the same time.

There are whole host of tools for controlling playback of lectures in the online course video player. Simply press the ? key while playing a lecture video to see the full set of controls. You'll see a help screen like this:

In addition to pause/play, speeding up or slowing down playback, you can also jump to 10%, 20%, 30% into the video by pressing the 1, 2 or 3 keys, respectively. This works for all 1-9 keys.

Please note that smartphones (iPhones, Android phones) have their own playback controls that supercede those we build into the online course system. Therefore, speeding up and slowing down the playback of lectures on a mobile device may not be possible depending on the device used.

Additionally, speeding up and slowing down playback of video does not work in Internet Explorer 9 or older versions of Firefox. By having an up-to-date browser, you'll have the full set of playback controls available to you!
