Bug Walk animation works fine, but only when object moves at slow speed

I have a hero with walk animation. After increasing the hero movement speed, the animation starts to appear a bit blurry and weird, why would that be? I've tried all kinds of fixes, using velocity, using translate movement etc, changing animation speed from 1 to 2 or 0.5, and nothing seems to have worked so far. Thank you.

 

What do you mean by blurry?

 

It's not my project, so I cant show it. But blurry like, your eyesight is slightly bad, it is not very noticable, but I think it shouldn't be like that.

 

Update: Dammit I found it, it's the goddamn camera update method, late update causes camera focus objects' animations to appear blurry, so changing to fixed update fixes it. But I needed late update for a script, anyway, ty for help, solved.
