Are you trying to pull off the floor like this is a conventional deadlift, or are you trying to use your clean setup?
Either way, your hips are shooting up first, and you are completely losing your back extension when this happens. You really need to focus on setting your back hard. Squeeze your chest up as if you were trying to point your chest at the wall in front of you.
If you get your hips up higher at the start, this will help with your hips shooting up first. If you are trying to pull with lower hips because that is how you set up for your clean, then your chest and hips need to rise together so that your hips don't move first like they are now.
