Sure it seems like a gimmick, but 3D FPV seems like a natural pairing. Until I win the lottery and can afford a Skyzone setup or even a rig large enough to carry an insane 3D GoPro rig, I’ll just have to live vicariously through others.
YouTube has support for 3D videos in several formats and there are several ways to enjoy the 3D footage without breaking the bank. Of course, if you already have a 3DTV, just use that. If you have a smartphone, you can use google cardboard.
I go old school with the blue and red “anaglyph” glasses. I got some relatively fancy 3D anaglyph glasses which beat the crap out of the paper ones you can often get for free. They also work with some 3D DVD movies I have like The Polar Express.
Anaglyph mixing of videos isn’t always available in the YouTube app on iOS (depending on the version). So if you want to use your red-and-blues with your older iPad or iPod, you can download an app called 3D Tube which will mix together the left and right images. It’s nice because you can specify the 3D glasses type and colors, and also make alignment adjustments to the picture for optimal viewing.
One of my favorites channels that has multi-rotor footage in 3D is PC3DM. You can browse through his 3D collection, but for sure start with this video. You don’t have to watch the whole thing, but don your glasses and watch at least the last 30 seconds 😎
