I'm working on that, as you can see by the video quality, I need a totally new camera! Which I am saving up for, and it will include widescreen, because widescreen is sofa king hot!
Also make sure you invest in a GOOD lens. Theres some cheap ones out there that blur toward the corners where the distortion is heaviest - you dont want that. A good lens with good optics wont do that. But it will cost you.
Dont put anything in wide screen format - it totally warps the images.
But then again, don't use too wide lense. Many people use fish eye, or very wide lenses when they take POVs, and IMO that gives poor results. I would prefer a lense close to normal, on a camera with optical image stabilizer. That is what gives the best result. Also it would be possible to make some sort of steadycam rig, but that is pretty advanced.
