Embedded videos are not working


The videos in this Prezi created by a colleague of mine are not working. Here is the link to the Prezi: https://prezi.com/qdhmkdl4as5z/the-earths-atmosphere/
The Prezi screen turns black and does not play the video.
Any ideas?



Hello @Michael_Miller, please convert your videos to mp4 and re-add them to your presentation, that should solve the issue!
