I'm not sure how long you've have this parrot -- so not sure you can determine her 'normal behaviour' yet in your home. I mean, maybe she was awake more before because she's in a new environment. Basically, she needs to establish her new norms in your home before you assume you're witnessing a behaviour change or not.
If she is eating and pooping normally, I would assume she is fine. She could love you and her new home but still be homesick and miss her former home and people. She may have good days and bad days. She's probably quite resilient but deserves time to settle in. Granted, the video you shared showed a sweet parrot, probably experiencing some Spring hormonal fever. But she could also still be adjusting to some major changes in her life.
Again, as long as she is eating and pooping, I shouldn't worry. At some point she does need a vet visit just to establish her health status and to get a baseline for you. But for now, I say let her settle in. Just because you knew her in her formal former home doesn't mean you can gauge her behaviour in a new atmosphere, with new routines, people, etc.. From your shared video I felt she was coping quite normally considering all the recent changes in her life.
