Create video tags to encourage Team members to "hashtag" their video. Tagged videos are easier to find when filtering in Feed, Library, or back in the Administrator's Video portal. Use Video tags to distinguish best practice library videos from general videos or use them to designate the video content, e.g. Math, STEM, ELA, etc.
Simple go to Setup, then Video Tags, and create as many tags as you desire. Your team members will see a drop down menu of these video tags when they edit the description of their video. See the companion article to see what your users see.
