Great results but looks expensive. I wonder how many minutes of processing per minute of video.

From the paper listed on the page it looks like it takes about 305 hours to process a 10 minute video. The vast majority of that is during the "source selection" phase which takes 1 minute per frame of video.

I walked around Boston once with some friends for 7 hours. When I remember it I see it as the hyperlapse, not moment for moment or sped up. Super interesting work.

I was thinking the same thing as I watched the video, that, this is probably the closest to how most people remember long stretches of time.

Earlier quoted context omitted.

It's certainly way better than the source video, but it's nothing close to what would come from a steadycam or dolly. You couldn't use this finished product in any kind of real production.

That depends heavily on your definition of "real production," and probably quickly devolves to no true Scotsman. I absolutely think this could be used in productions I would consider real, particularly documentary/travel/reality programs and sports.

Yep, it has a definite 'look' to it, and it appears to work better for some types of material than others (the bicycling footage was far more watchable to my eyes than the climbing stuff), but the effect is engaging and not unpleasant to view at all.

Couldn't it be done with a wider angle lens, a better imaging sensor and conventional image stabilization techniques? If such captures become commonplace, it's easy to imagine capturing with a wider field of view so that the stabilizer would not be so overtaxed.

Bloody amazing! Fantastic work! Release it. Release it soon. This is something that everyone would want. I see they have listed a Windows app coming. Is that Windows desktop app?

If I were them I would offer this as a web service: upload your video and have it converted for $1.

That's obviously the most useful solution for us. Don't know if that's the best solution for microsoft. I'm surprised there weren't a bunch of logos and catch phrases like "Only on windows" or "powered by Microsoft!"

They said they'll offer it as a windows app, and I imagine it's for very corporate reasons.

I don't understand how computers figure out 3D from single camera video without parallax. How do they do that?

You track points in the scene across frames. This helps infer the 3D position though getting good accuracy is hard. Basically parallax gets created in time as the camera moves.

I recall those childhood days when we could not explain why moon appeared to come along as our car moved. :-) Those differences in apparent speed betrays something about the distance of the object/point under consideration.
