The Media Gallery in Blackboard can be used to share videos (that both you and your students can add) within your Blackboard course. Access the Media Gallery from the Tools menu in your course.
Videos can be added to your Media Gallery by selecting the Add Media button at the top of the Media Gallery page. Selecting Add Media will open your My Media library.
You can select previously uploaded media, or click Add New to upload/create new media. Once new media is uploaded, select it and choose Submit.
The course instructor may moderate the Media Gallery, so student videos may not appear right away.
