You Can Now Control the Speed of Video Lessons

ostraining video speed

The most requested feature at OSTraining was the ability to speed up videos.

Many of you squeeze in time for training and want to progress through the training more quickly.

You can now run the videos more quickly at 1.25x, 1.5x or 2x. If you want to, you can also run them more slowly, at 0.5x or 0.75x.

Here’s where the speed controls are located on OSTraining videos:


You can see those controls even more clearly on the mobile version of the videos:


Browser support

One of the tricky things with this feature is that it is HTML5-only. Some browsers will force the video to fall back to a Flash player which doesn’t support these speed changes.

That means that it works in these browsers:

  • Chrome
  • Safari
  • Internet Explorer 10 and 11

Support for Firefox will arrive in mid-January when Mozilla launches version 35.

How did we add the speed setting

We’re using a plugin called OSWistia Pro. Our videos are hosted at

OSWistia Pro has whole range of improvements to normal Wistia videos, including “Playback Rate”. You can enable speed changes, also choose who has access to speed up your videos.



We’re going to keep working on this feature, making it work on more browsers and hopefully improving the interface also.

But, there is no truth in the rumor that we’re going to add a 5x speed called “Micro Machines Speed”:

In the new videos variable fast type are you planning for automatic subtitles?

Hi guido36
Yes, subtitles are something we’re thinking about adding. There’s a bit of tradeoff between creating a lot of videos, and adding subtitles (which slow things down) but we’re working on it.

Would love your thoughts, please comment.x
