I hope, it will be interesting (curious, at least)
Lumix DMC TS1 + wide lens 0,45x
This is my 'main' camera, recording at 720p on the helmet with the handicraft angle lens conversor that you can see here.
DRIFT X170
Is a not well known camera, was mounted on the top of the helmet of Ruben. Ruben follows me riding 'Los Pepes'. You can see here some extended videos.
MiniDV MD80 "shitcam" + wide lens 0,38x
The 'shitcam' was mounted on the helmet facing back. Helmet is not the best place to mount back-cameras, becouse in cornering the image moves out excessively to sides. Camelback is better place to do it.
Definitely, the 'shitcam' has not quality enough to fill an HD format. The video comes with 30,9 fps more or less (not any standard), jumps every few frames and has a lot of wooble.
Footage from X170 and 'shitcam' fits well into little windows, but in the big one the difference with Lumix is notorious. So I decided to use short appearances and colours.
