It's a still image. Is this just one footprint, in isolation? Did Bigfoot fly down, plant one foot in the snow, and then fly off again? Or is this one example in a series of footprints - a walking track? If the latter, a podiatrist can infer a lot about a creature's gait by the pattern of footprints they leave. Heck, last time I bought a pair of shoes they did this in the shop with a simple machine. If the gait is not consistent with that of a living being - if it doesn't have a stride pattern that can be analysed by an expert, that is sufficient evidence to conclude that the print is almost certainly a hoax.
You can't tell a lot from a single print. Do you have a link to the video from which this still image was taken?
