Get your 3D glasses out! Using my new GoPro 3D Housing, I can use my two GoProHDs to make 3D video. I don’t have a fancy 3D display – just old fashion red-cyan glasses that you can get for free or cheap. I’ve found the videos work best at full screen, 1080p, in a slightly darker room. YouTube has options to pick which type of 3D best suits your equipment (if any) by clicking the “3D” button. You can also turn it off and watch in normal 2D. My one complaint about using red-cyan is that it makes my SV look brown instead of red.
