Edpuzzle will allow you to locate youtube files, load them into edpuzzle, edit them to cut down to only what you want, record an introduction, insert questions, and upload a shared link to Converge. This will allow students to access content with additions you have made.
Here is a tutorial on how to use Edpuzzle. The only difference in how I use this resource is - instead of having a classroom, I share a link to the video. I then copy and paste that link into Converge for the students to use.
