I have been placing my stock footage for sale on multiple platforms using a service called BlackBox Digital. The video contains footage I have taken from beaches near my home. Short segments like these are uploaded onto BlackBox and they distribute to several other outlets on your behalf.

So if you have a drone or two, an FAA Part 107 certification, and a little free time, why not try selling some of the B-roll?
