Sorry if this has already been mentioned (these threads move so quickly!), but I think the reason Meghan looks so different in the video is because she's using a very strong filter. It's really amazing the kind of filters you get now, even for video.
What gives it away is the much lighter colour of her eyes, but also the distance between her eyes.
Her eyes are slightly too close together and I always notice it, but here there are normal distance apart. There is so much of a blur effect going on too that the inner corner of her right eye has disappeared.
