The most noticeable issue with the jerk is that you dip and drive the weight forward...
I added the vertical red line as a reference point for the sequence. As you can see, as you commence the dip, you slouch forward and shift your weight to the front, thus throwing the bar significantly forward.
Try to keep everything tight (tight back, big chest) and maintain the weight towards your heels as you dip and drive.
Good luck!
