Yea just looks like your upper back looseness is causing the bar to roll forward and for you to ultimately lose the bar forward your midfoot. Put the bar where it needs to be (slightly lower than where it is) and think proud chest all the way down and all the way up. Also, don't think about "cranking your elbows up" but rather pin your elbows to your side and retract your shoulders blades as hard as you can.
