Beginning September 22, YouTube videos embedded in your Canvas courses may begin to display ads. This is due to a change made by YouTube. In response, Instructure (the vendor for CarmenCanvas) will display an overlay message warning users that ads may appear. This message will appear before a video plays and must be clicked through by each user.
If the YouTube content in your course is your own, we encourage you to explore moving it to Mediasite, which is fully integrated into CarmenCanvas.
Consider reaching out to University Libraries to see if they can provide access to the media you are sharing. Several of their platforms, like Films on Demand, allow for clip creation.
