To access the Media Library, go to Site > Media Library
The Media Library is the location where all media files uploaded to your site are stored, regardless of whether they were uploaded through courses or not. Within the Media Library, you have the ability to perform various tasks.
You can also upload videos up to 2GB in size, which is larger than the 1GB limit for course uploads.
Note that in the Media Library, you can also edit videos with many options and tag the videos for easier filtering later.
