I didn’t see any hammers moving. Coupled with the lack of a soundboard, I agree with the conclusion that this is a digital piano masquerading as an acoustic… or there’s no piano at all and she’s ’key/finger syncing’ with a pre-recorded backtrack.
She seemed a little winded — not sure what came before, but I’m guessing it was pretty energetic, and she was moving a lot while playing. My guess is that this is optimized for theatricality rather than actual piano playing.
On the other hand, she did move her right foot at places that seemed pretty reasonable for pedal transitions. Although with those heels the foot/leg motion is very different from what I do! I tend to flex/extend at my ankle to engage the pedal, but it looks like she has to lift her whole leg from the hip!
