They _could_ have inserted out-of-order frames as they were completed, and she could have been commenting on witnessing the video moving from flat vector gfx to jelly bean gfx.
They could have, but I have a feeling they didn't. There's also the fact that in the last frame they shot, she's wearing the space suit that is, in fact, what she's wearing at the end of the video.
They did. If you watch the second video (the making of) they commemorate the last "Kina shot" where she is dressed as an astronaut which does not match the last sequence with her of the movie.
She implied it when she said that after every day, they could see the progression up until that point.
