Edpuzzle streams videos from YouTube using their embed APIs, which means that we (you included) are in compliance with copyright laws. Of course, this is provided that the original video isn't infringing on anything, in which case the video could be taken down at any time.
The original video still accumulates YouTube views when it's watched on Edpuzzle, because we do not use the Auto-Play embed. This means that the user has to click play in order to watch the video and it's verified that someone is actually watching it (and it's not just automatically playing). Through YouTube's embed API, advertisement clips do not play, but the pop-up banner ads still show in the Edpuzzle video. This is important if the owner of the video is making money from advertisers, to assure their video content and ads are being seen. Again, this is in compliance with YouTube regulations, as long as you are not making money directly off of video content that you do not own.
It is our policy to respond to notices of alleged copyright infringement according to the Digital Millennium Copyright Act. If users upload videos that violate copyright laws, we will remove the videos, and will be forced to delete the accounts of users who have multiple violations (or even one-time offenders, if deemed appropriate).
