Use a pair of XREAL video glasses as a handsfree viewfinder. The XREAL glasses look a bit unusual, but they can be worn and used like regular sunglasses. The camera outputs HDMI via a distressingly fragile micro-HDMI connector, but the glasses accept video over USB-C (aka DisplayPort altmode). The finishing touch is putting a neck strap on the XREAL glasses, allowing them to be easily donned and doffed as needed while filming. The camera has a handle for this purpose, but the process is much better now that the glasses can act as a viewfinder.
