thanks, that sounds like a good setup.
I was planning to do capture in sub-zero temperatures, but (probably luckily) the weather wasn’t great.
My idea for the setup involves some tethers for the cameras going into the interior (might dent the car, but keep the cameras at least), as well as power supplied from the lighter socket to all cameras.
Fusion goes on the dji mount with an aluminium selfie stick to elevate it, gopros go on the gopro suction mounts, and potentially extension arms like the ones you posted.
now I just need the time to set it all up
