Bigfoot - also commonly referred to as Sasquatch in Canadian and American folklore - is a large, hairy ape-like creature said to roam about in the woods.
Nv Tv - the 'largest database of Bigfoot, Sasquatch, Yeti, Skunk Ape, Yowie, Werewolves, Dogman' and other cryptid content - recently posted the video on YouTube, saying in the title: "Incredible Muscular Giant Sized Sasquatch On Camera!!"
It also adds that the footage was captured in Idaho, USA, while going on to say in the video itself: "After watching the clip and looking at the amount of detail in this 'suit' we thought this is something real you can not buy online.
"The Bigfoot in this video looks very real and you can even make out the heavy build and all the muscles which is hard to replicate using a fake suit... Plus who in their right mind would rent or buy a suit just to pull off a hoax?"
I mean, I can think of quite a lot of people who would happily go elaborate and extravagant for the sake of a prank, but sure.
It continues: "This simply can not be a man in a suit only because there is so much detail in the body and it looks MASSIVE in size."
The sighting has yet to be officially registered on the Bigfoot Field Researchers Organization (BFRO) website, but it seems some people already feel fairly convinced - with many saying the quality of the clip is even better than the legendary Patterson-Gimlin footage.
Paul Seaburn of MysteriousUniverse.org said: "Whatever this is, it's BIG. Big head, big butt, big body, thick legs, large arms. That would have to be a pretty large human to be a person inside of a costume.
"Along those lines, if it was a human in a costume, its wardrobe assistant managed to find one with a pretty snug fit. You don't see Bigfoot impersonators in costumes that realistic... if this is what Bigfoot really looks like. The gait is a normal walking gait - nothing bearish or ape-like about it."
Another analysis over on UnexplainedMysteries.com seemed to be a little more cautious, saying: "Very little is actually known about the video or where it came from and there doesn't seem to be an explanation for why the person who recorded it stopped filming after such a short period of time.
"The video caption notes that the level of detail present in the 'suit' makes it unlikely to be a hoax, however, without additional background information it's impossible to say what's going on."
Enthusiasts commenting on YouTube seemed fairly divided - with some seemingly convinced, while others remained dubious, saying it's hard to tell if we're not seeing the full clip.
One said: "This footage is better then the Patterson Gimlin footage. Best I have ever seen."
Another person wrote: "All the movements are right especially the way it picks up it's leg, and it's built about the same as a white BF that I seen years ago. No way it's someone in a suit. It's either real or someone spent a lot of time and money making a CGI video."
A third added: "What human is built in the neck like that... and that girth is serious... look at the shoulders deltoid area...seriously..."
A potential naysayer, meanwhile, commented: "Only problem about this video is, why wouldn't they continue to record? Why just stop recording after a few seconds & not continue to record it?"
Another agreed: "There's nothing here that can't be faked. Looks like an Orc from LOTR. Where's the human shot in the same location for scale? Why is there no story? What precipitated the 'encounter' and how did it end? Just doesn't pass the smell test."
