I'm not sure I understand your recent reply in this thread. I tried to address your question saying that you can't make Canvas Studio only available to some people/courses and not to others. Canvas Studio is a tool that is available to everyone at your school via the "Studio" icon on your left-hand global navigation menu. Further, once instructors have embedded Studio media into their courses, they can click on the "Studio" course navigation menu to access any media that is a part of that course. (Students do not have the "Studio" course navigation menu, they only have the "Studio" icon in the left-hand global navigation menu.) Again, if you are concerned about storage space for Studio content, you should reach out to your Customer Success Team at Instructure to see exactly how much storage space you have available for Studio content. Also, if you are a Canvas admin, you also have a Studio analytics screen that would show you some helpful information about all the videos that are a part of your school's account.
I hope this additional information will help to answer your questions.
