The angle here is somewhat limiting, but a few things:
1) Your wrists are not stable and actually bend a bit in the takeout. Do you have wrist wraps?
2) Hard to tell, but I think your elbows might be too far forward in the setup of some of these reps. Have them just slightly in front of the bar.
3) You need to get tighter in the setup. Squeeze your abs and quads harder.
4) Doing more than 2 reps in one breath is a lot. It can accumulate a lot of setup/bar path error and you will also lose a lot of tightness. You need to pause, reset, breathe and get tight more than just at the beginning of the set.
