Is it just me, or is the warping sort of noticeable?
It feels like there's some sort of other-worldly quality... I think it's parts of the mesh moving around out-of-sync with other, but it's really hard to get a sense as it's one of those things where it's the image as a whole, not any one point you can look at.
Honestly, it makes me slightly nauseous - I'm not sure I could deal with it for a significant period of time.
I think a lot of the otherworldly quality is simply that they've put the camera on a line. Not "sort of a line", not "a steadi-cam pretty-close-to-line", but a line. Very few shots ever are actually on a rigid line, especially at a single rigid speed. Even track shots will do some panning, or travel at different speeds throughout the shot.
This is easy to fix, of course. For demonstration purposes, it really drives the point home that they have stabilized this picture, no ifs ands or buts. For real use, I'd probably stick with the lowpass filter. Also, in real use, you'd be able to configure the algorithm selectively; line here, lowpass there, etc.
I've watched it twice now and I only noticed warping during the scene with the water in the background and maybe a smidge on the big road cone in the stairs scene (though that might have just been some exposure shifting).
I figure they've still got some bugs to work out anyhow.
