Salt flats in FPV might look like a snowstorm. If you want to record video, it is best to use a camera with on-board HD recording onto a memory card. Caddx and others make them. The recording through goggles or any other remote video device is not very good at all. Lots of noise from the transmission over RF and low resolution. Otherwise, all you need is a camera, a VTX, and your goggles. FPV on cars is a lot of fun, and works very well.
