^ Would be cool to incorporate a third cam. Two as currently configured (maybe turned 90 degrees) and the 3rd with a tighter-field of view for greatly enhanced resolution along one primary axis.
I've schemed about something like that for decades, small enough to be placed atop my mic-stand along with my surround recording rig in the center of amphitheaters and festival venues. And such a scheme would represent a cool videographic parallel to my basic philosophical approach to location music recording- that is a basic division of labor to capture the direct sound (primary image axis) as cleanly as possible, plus separate capture of the ambient and reflected sounds arriving from all other directions which excludes the direct sound as much as is practical, allowing for the optimal re-synthesis of the two when cooking it all back together again.
I have enough to handle with audio alone, so I'd only do it if such a thing was made by an outfit like Zoom and was pretty much set and forget, and it wouldn't be worth it to me at all unless the primary axis quality was sufficient (the downfall of ambisonic capture for surround audio IMO, and why I choose not to use a single coincident mic array)
But its fun to think about adding 360 video projection to the portable surround playback pop-up-canopy project I've talked about here but have been dragging my feet about for years. I have collected a 12' hexagonal pop-up + 8 DefTech speakers that fit nicely into one Pelican suitcase, but have yet to run wiring through the canopy members such that it can be easily collapsed for transport. Scheming on another identical Pelican or two and building subs and into them. This project is unwieldy enough on its own without incorporating 360 video projection! That's just too much I think. I'm no miniature Disney World.
