I know a lot of people focus on video recording on quads, but I also wanted to throw out how still photography is also rather useful.  I know someone who does some work in civil engineering and such.  He takes a high volume of stills with GPS info embedded in the image metadata.  He then uses a program called PIX4D to render the images into a 3d model that can be printed or manipulated to show potential modifications.  I was surprised to learn that the 3d model is accurate to about 1.2 inches of accuracy.  So don't rule out pairing still imagery with your quads.

My old syma and DJI P2 does stills also.

Seen people carry both, a FPV, plus a gopro or the like.

(FPVs are kinda janky on image quality, scratch that, they ARE janky)  But it gives you a shot of what you are looking at with the gopro for the HQ pic/vid.  And if you have a gimbal, you could possibly have both cams moved together.

I hadn't thought about using stills from a video source.  With video being what it is now, that is probably more viable than it once was.  Thanks for the thought fuel.
