1) I feel like I'm watching a slow motion B horror film. Don't you guys have iphones and windows movie maker? Gracious.
2) The angle from the first video is damn near impossible to tell anything.
3) The second video...ah hah - here we go... Now we have something to work with...
A) Your stance should put your shins 1" from the bar. It doesn't. You are about 1/4" from the bar, which puts you too much on your heels which is extremely prevalent in rep 2 of the side view, where the entire ball of your right foot comes off the ground. - Get 1" away from the bar, grab the bar with straight legs, then push the shins forward without rolling the bar until they touch the bar. THAT will put you at the proper shin angle.
B) Probably because of this same issue, your shoulder are not in front of the bar enough - it appears you think you need to get your shoulders behind the bar while pulling - the opposite is true. Shoulder should be slightly in front of the bar, bar is over midfoot, and weight is balanced evenly over the entire foot.
C) Possibly the most atrocious thing about the deadlift is the way you put it down, where-in you bend your knees to lower the bar with your legs. The eccentric portion of the deadlift should be fast, and is done with straight (extended) knees - you bend at the hips first, shoulders go in front of the bar, and when the bar passes the knees, then they bend to finishing lowering the bar. This entire sequence should be done in about 1/2 a second though.
