I messed around with some settings in gimp, and ran it through an upscaler, this was the result. I am definitely leaning towards bear, because of its size, the shape of it's snout, the color, and also 
This chart here where it explains black bears eyes can reflect red. Maybe not a full grown adult bear, but a younger one. I still have trouble telling its distance and size though.

Look at the shape and length of the snout here. From the right angle I definitely think it could appear as long as it seems in the video
