If your course includes videos you may at some point experience video playback issues depending on your web browser and flash setting.
Below is a list of solutions to common problems:

If you see this message, try to refresh the browser page in order to reload the video, this will generally resolve the problem.
Why is video playback choppy?
If your video playback isn’t smooth, here are some things you can try:
- Try letting the video buffer before you view it.
- Close other browser tabs and windows. This can make a huge difference!
- Make sure you have either the latest version of Flash running on your computer, or use a browser with native HTML5 support.
- Switch to another web browser to see if that helps.
What is video buffering, and how do I do it?
Buffering is a way of preloading the videos you watch so that fluctuations in your Internet connection don’t cause choppy playback. When you play a video, a light grey bar will advance in front of the playhead, showing you how much of your video has been buffered. Your playback should be smooth as long as you’re viewing your video within the light grey buffer region.
If you’re experiencing choppy playback, pause the video, allow the video to buffer for a few moments, then try playing your video again!
What browser can I use with the video?
We support Google Chrome, Safari, Firefox, Opera, and Internet Explorer. Whichever browser you prefer, please use the most up-to-date version available to ensure that everything on the site works smoothly! You can update your browser(s) here:
You’ve asked me to clear cache on a page or the browser. How do I do that?
To clear the cache in your browser hold down the shift button and reload the page. This method resets the information about the page that’s stored in your browser.
What does “Scaling On” mean?
This means the video is being stretched to fit your screen in full screen mode. If you click the Scaling off button in the player, you will see the actual size of the video, without any enlargement.
Can I watch HD in its native resolution without scaling?
Yes, click the full screen button in the lower right corner of the player, then click the button that says Scaling is on to turn scaling off. Your preference will be saved for all HD videos you watch.
Do I need a fast Internet connection for HD videos?
Most residential cable and DSL connections should be more than adequate. If HD feels slow to load, try turning off any background applications that could be using up bandwidth. Or push the play button in the player and then pause to let the video buffer before viewing.
Is my monitor capable of showing HD?
All modern computer monitors are similar in resolution to HD, if not better. Your computer is a sleeping HD beast; the video will rouse it from its slumber.
What is hardware-accelerated decoding, and how do I disable it?
All videos need to be decoded in order to be viewed. In other words, the data within a video file is interpreted and rendered as sound and images for playback. Our videos are decoded using either your browser’s native decoding technology or Adobe Flash. Hardware-accelerated decoding means that your computer’s hardware is used in addition to your browser or Flash to decode the video. Depending on your particular hardware configuration, this may affect the look or sound of video playback on the video (and across the wide world of the Internet). When troubleshooting playback issues, you may want to try enabling or disabling hardware-accelerated decoding. How you do so will depend on whether your browser uses the videos Flash or HTML5 player. (FYI: Not all browsers or operating systems utilize hardware-accelerated decoding.)
