The 2 biggest issues I see are:
1) There is a general lack of tightness in your setup, which results in you jerking the bar off of the ground when you finally decide to pull it (I call it going 0 to 60). In order to achieve tightness pre-pull (squooze, as Coach Wolf calls it), you must lift your chest by pulling AGAINST the bar. You may very will be "lifting your chest" relative to your hips, but if you are not pulling up on the bar while lifting and rotating the rib cage, you will not be tight prior to pulling.
There is a general misunderstanding of the "lift the chest" cue in the general population (at least on the forums and in the facebook group). Lifting your chest does nothing if your arms slack/not under tension. You must produce force against the bar while lifting the chest in order to produce "wave extension" in the back, as the book describes. This is the tightness required in a proper deadlift.

Jake, watch
Squeezing the bar off the floor | On the Platform - YouTube, and pay close attention to Coach Niki when she says "the bar should feel heavy in the hands and heavy on the feet" (paraphrasing). You must achieve this while lifting the chest.
Try it out, and let me know how it goes.
2) You weight appears to be out over your toes. This, along with (1) is why your hips drop and the bar casts away from you right before the bar breaks off of the ground. We pull from midfoot, not on the toes or through the heals. Look up step 4.5 of the DL setup. Without dropping your hips, shift your hips back to get your weight off of your toes. It may feel like your are on your heals at first, but this is because you are use to being on your toes.
Once you figure out 1) then worry about 2). Let me know how it works out for you!
