Thanks Onno, that's exactly what I'm talking about. Fun commercial, btw. I think that by now, it's safe to say that there's no real name for the rig, or rather, no universal name, so I'm going to call it a 'FIXED FOLLOW RIG.' I considered the name Mark Dunne suggested, but POV implies a subjective shot and I don't think that captures the full extent of the rig, but I will take his advice on naming it. So just to make it official...
I, Oscar Perez, do declare, on May 26th, in the year of the Lord 2016, that from this day forward, an immobile object in the shot, which is rigged to the camera, shall be called a 'FIXED FOLLOW RIG.' No longer shall this set up go through life nameless, like a unloved child.
I hope that works for you guys. Let me know what you think.
