I haven't watched the clip yet, but I will shortly. In the meantime, a brief comment with regards to wildlife video vs photos, if you will.
Given that with video you're able to capture wildlife behavior over a period of seconds to hours, traveling to exotic locations is less important to producing an interesting video than taking the time to observe and document interesting animal behavior that occurs everywhere around us, even in the macro world.
With the capabilities of today's cameras, even down into the mid-range models, for the average person, capturing decent images of exotic animals is more a matter of time and money than skill and perseverance, though to get to the level of Steve and others who make or made their living selling their work, both skill and perseverance are required in spades!
Shooting great content to produce and edit even a short video can be quite another matter with a whole new set of challenges to overcome and skills to learn, but well worth the effort if you enjoy sharing something you've seen or experienced that held one's interest for more than 1/2000th of a second.
I know there are many who are in the "I never shoot video!" camp, that's perfectly fine, totally get that...and many who never shoot stills, either. I do what I need to do to share something that interests me and I use the best tool to do that.
Cheers!
