100 frames HD version is here now (i slowed it down a little in Sony Vegas).
No other effects then a little color correction on this one. The other one had a motion trail effect for example.
This one does have only a little blur because of the slow down. But a little motion trail might look better i think.
It smooths the motion and looks a little like crumbling stones to sand i think.
Downloading the original one and loop playing it locally might be better.
Dorianvan, i wanted to render without GI but had a problem with PixelPlow(haven't searched, most probably my fault).
So i used very small GI numbers and a 5 frame interpolation. But there is basically no GI in the renders.
It was a fast crude 3 light setup. Would look better with a real GI approach most probably.https://vimeo.com/196969237
