Hmmmmm,
Looks like a feral cat to me . Seen them in various colors including black, white and everything in between. Some were rather large, the kind that will likely be tagged a "big cat" more times than not. This one moves and looks much like a feral to me, hardly the "king of the jungle" type attitude with a deer that nearby.
I myself thought that I had seen a "black panther" when I was in high school. With a little closer looking it turned out to be a Feral cat. If he would have ran off a little faster I would have been a believer myself. Fortunately he didnt and I am still a "believe it when I see it" kinda guy. With as many "wives tales" and so called sightings floating around in our heads, our minds can make us see what we want too, alot of times. In reality there has never been one killed, or even pictures or video that closely resemble a "big black cat" in my boook(this one included).
This video proves nothing to me. Grainy, shaky video of a feral cat is far from conclusive in my book. The distance and angle from the deer stand makes this cat look bigger than it probaly was.
I can believe black bobcats, Ocelots, Jaguars, and other PROVEN findings. But the "big black cat" will likely just be another Big foot in this part of the world. With as many trail cams floating around the woods these days you would think one would slip up sooner or later....must be later, or more likely never.
Take care,
Todd
