How do I change video background in Premiere Rush?
Hi
My college Children's Literature class requires that I shoot a video of me reading a book for the viewing audience and providing a series of informational trivia after the reading is finished.

I don't really have an appropriate reading nook in my home, so I'd like to record it and change the background to a solid or muted/blurred image background.
Is this possible with Adobe Premiere Rush? I can only afford the $10 Adobe CC Creative Suite right now, so I can only work with the software solutions that provides to me.
If post production video change to background is impossible, should I just shoot in front of a sheet or something? Any and all help is requested, appreciated and will be utilized. Thank you!!
