I'm somewhat left wondering what really happens to the high frequency bits? Can they move around a lot like in the style-transfer examples early in the video? It seems a bit like this method assumes the image will not be 'deformed' much overall and will stay basically in the same location (which I think is a bit less interesting than the full style-transfer examples they show at the start to compare tbh).
