It is done. We just added the first movies to HDRI Hub. Now available are some sky time lapse movies that you might find useful to use as backplate for your renderings.http://www.hdri-hub.com/hdrishop/footage
We try to achieve high quality and so we provide them as ProRes 444 format.
If you have problems with the preview movies, just let me know and we will change the player.
More too come soon and of course any feedback is appreciated.
