thx - I know the overview - but I try to understand why the H3Pro6n is the prefered Rig for UAV/Helm Mount. And why we should not use the H3Pro7 for that purpose? And if H3Pro7 is better than the H3Pro6n.
Trying to figure out which Rig to buy for our usecases.
The H3Pro7HD is not in Question as we ant to go for fullsphere. (H3Pro6 or H3Pro7)
I think its about workflows....
the Pro6 and the Pro7 can be put easyly on a monopod. and here the nadir is minimal, no patching needed. with go por helmet mounts you dont have monopod like mountings, like: http://www.camforpro.com/GoPro-Grab-Bag_detail_85_250.html
here its getting difficult to an patching free nadir. but additional the cams are mounted to not to minimize the parallax errors. you would have to move the the pro7 30" and the pro6 for 45" to get lenses oriented horizontally to reduce parallax errors. to do so you need extra mountings to attach all on the helmet.
The Pro6n has horizontally alligned lenses by default and plenty of room to attach the mountings between helmet and the 360" mount (but a big patching area unvovered by video)
so for full spherical video + patchless nadir + not to close objects (2-3m+ I would guess) + not to fast movements (highspeed boat, downhill skiing/mountainbiking etc.) I woudl go for the Pro7. if you need closer objects + more speedy eventy than incline the moutn 30" to reduce parallax but than I would guess you will have artefacts in nadir coming from the mounting between the rig and the helmet.
PS: a collegue is using up the normal plastic mounts available from gopro like chocs... hes mounting 1 hd3 on his 800cm2 bike. the vibrations are breaking them on daily basis.
so if you go extreme sports I would suggest to buy an 3D-printer like http://www.conrad.at/ce/de/product/409630/Velleman-3D-Drucker-Bausatz-K8200
and print your own rig. with rig 3-4 its getting cheaper than buying them... minimum go for alu mounts and not for plastic ones...
PPS: but also I think the seen videos until now (regardless of used rig) dont convince me. its really bad quality. dont know if this is the hd3 (caution: the hd3 is getting realllllllly hot if used more than 30min. crashed, reboots are you best friends - I think this got much worse compaed to hd2 - I also had collegues selling their hd3 again to buy hd2. for web no quality difference, much less space needed and much better cam robustnes and much cheaper too.) or the rig or the stitching software - or just the until now used reduced output quality to reduce the final filesize).
