I've heard that scraping noise before Leah, it was some turned out to be some mud had collected and dried underneath a fender. To find it, I got off the bike, used the second top tube as a hand lift, raised the front wheel off the ground and spun it slowly, then did the back by lifting on the seatstays. Then you can check the clearance of your fenders and brake pads, etc. It's easy to change the spin rate and all that. If you happen to have another person to hold the bike while you look and listen, that's great too.
In your case via the video the sound of the scrapes didn't have a constant note or rhythm. What I can't see in your video is you turning the crank and the entire motion of everything, to see if the scrapes match the rhythm of the cranks or not. It must be scraping on multiple places. Mud/debris in fenders can do that. It would really help if the bike was in a stand though, so you can simply spin the wheels and crank by hand back and forth and such. I'll listen to the video layer when I can slow it down as I'm on a Chrombook at the moment.
