Hey, first author here. Good questions.

The simulation runs in realtime, and is interactive. Generating the simulation can take a while though.

The 5 second video took about a minute to process on my laptop. But longer videos, and higher-resolution videos, can take much longer. For instance, we've used the technique on high speed video to recover audible vibration modes, and this can take hours to process because the video itself is so big.

I wrote the processing code in Matlab, and the simulation in c++ and GLSL. The simulation is pretty well engineered because I wanted it to run in realtime. I didn't put a lot of time or effort into optimizing the video analysis part though, so it probably could be made faster.

Hi!

Thanks for responding to my questions! The whole project is amazing and I hope you keep working on this (and future projects) with the same enthusiasm as you do now! :D
