JFC her form again, air bubble runners, rocking feet, knees caving in, her 2nd last was a fail too, hips didn't lock, never mind shes not lifting right at all, her arse isn't dropping, so shes using her lower back more than her legs, bent elbows, which means shes not bracing at all. She's seriously lucky she hasn't permanently damaged her back tbh at this point.
Deadlifting is not about banging out reps, there's a whole mental/body chest list to go through to get your body in the right form and protected properly. That gym is a joke.
