How can I remove an object from a shot? I’m attempting to remove a head mounted GoPro in a mirror shot, exactly as seen in this video, around the 15 second mark: 


                
            

I’m using premier pro cc 2018, and I’m just looking for some ideology, or methodology on how to do so. Obviously a clear cut solution would be ideal. Thank you.
Object removal is usually done by masking, tracking and inserting a clean plate into the masked area.
Easier done in After Effects than in Premiere.

It looks like in the above video it is a different shot inserted into the mirror.
