Thanks Etienne
HD is still pretty low resolution it is always best to shoot stills (and always straight down)
- 720p (1280×720 px) = 0.92 MP
- 1080p (1920×1080 px) =2.07 MP
- (4K UHD) 2160p (3840 × 2160 px) = 8.29 MP
- Shoot stills with an old GoPro (Hero 4 @ image every 0.5 seconds) 12 MP

The software (I use Agisoft) is pretty good at removing barrel distortion (have a look at a standard GoPro and how much it puts in http://img1.skisoo.com/2012/09/fisheyeCorrectionFeatured.jpg)
The biggest issue I have found is ISO and blur from motion hence better sensors and more light (sort of) as a solution

A second battery housing and something like your battery holder (sorry mate most likely a home build) are the most likely the 1st port of call (as well as the burn wire system)
Thanks
