Two good comments I immediately notice in the comments section:
"The person last in the line is wearing a light coloured garment around their neck. The person who trots forward when the others stop has quick movements, appears small and maybe an adolescent. The adolescent is holding something in their right hand, possibly a camera, or holding the top of their coat together. The legs are long, the arms are short. This is a family of humans. (I have seen this posted elsewhere as a Bigfoot video.)"
and
"The way the first one is walking it sure looks like a person walking in snow shoes to me, same shuffle. Any others seeing that?"
And I agree with these comments. they are walking like humans especially the lead one in the front; the stride is was too quick and short to be a large and powerful ape creature.
This old video from Russia as actually more convincing for me:
It is actually moving the way a large and powerful bipedal creature with very wide back and long arms, would move across uneven snowy terrain and it has a confident and powerful stride.
And here is another interesting one. Harder to tell what is going on in this one but it is interesting footage nonetheless:
