I like to read bigfoot stories because they are interesting, but I don't believe this at all. And it's too outlandish, you can compare a bigfoot to a bear for most claims against their existence, however it's still highly unlikely they exist. His video proof could be fabricated super easily, and that tree branch doesn't move that naturally. And I looked at another video of his, this one
https://www.youtube.com/watch?v=UTwILtapBUg and that looks like it is a large black bear licking the camera. Another one claimed to have caught bigfoot on a back camera, but it looked like a burnt tree stump. His videos are all under like 20 seconds of recording looped about ten million times with his face thrown in their for good measure, would not be that time consuming to fake any of them.
