After watching the YouTube video, the extra little bob down and back up when the character shifts to the left when climbing the ladder does look strange. It isn't as noticeable with a high camera angle, but certainly stands out when the camera is near horizontal.
If that is what the animation looks like for everyone, I hope the North American release and next patch fix that. The second German patch improved some animations, so hopefully they did another pass looking for problems.
My machine is slow, because of that the movie recorded with fraps looks like if it has "cut" some frames. Runing the game without recording the movie make the strange "bob down and back up", as you said, more noticiable.
