Yes, I am here :-)

This would be possible. Although it would require providing some UI so the user could specify which parts should be sped up.

I've seen the Pjong Yang video, it is beautiful work. It requires very careful planning and shooting, and a lot of manual work to create such nice results. We're trying to make this easier for CASUAL, but it's still FAR away from the quality of professional hyperlapse.

Great, now we can ask you questions! :)

Some of the videos demonstrate unusual "popping" effects and deformations when standing still - especially notable in this video, top right, sixteen seconds in:

I understand how the extreme situation of climbing is a challenge, but what is it about standing still that causes this? Do you have any thoughts on how you might tackle this problem in future work? (although it appears you already combine an amazing breadth of techniques, so I'm not sure how many options you haven't looked at)

It would be cool to mark segments for different speeds of hyperlapse, or normal input. Thinking about that I see what you are saying about a casual product. Anything beyond a uniform render becomes complicated. People would want to tweak the knobs and see the results, so possibly a faster "preview" algo that allows you to see the timings. Or a feature to quickly render just the (t-N, t+N) around the borders.

The authors are at Siggraph in Vancouver this week, just saw them today. Likely they are too busy to read this thread today or tomorrow.
