This video was uploaded yesterday, and have received minor attention since, with about 300 views.
Information from the uploader:
“Footage filmed by a family camping in the forest of Fontainebleau, France, April 2011. Further info pending, will post when i receive it. Is This Smoking Gun Footage, Finally, You decide.”
Pay close attention to the left of the tree from about 00:35 and forward.
My initial thought that it was some kind of cow or calf, which is also heavily suggested in the comments field.
But when taking a closer look at it, it appears to have something resembling an hand, which a cow or calf doesn’t have.
With todays technology it could very easily been a CGI hoax, so I’m very interested in which direction this story moves forward.
