Copied from the Tears of Steel website. A great opportunity to work with 4k material and to use it for demos and tutorials.
"Thanks to our friends at Xiph.org we now can offer everyone access to the original source footage of Tears of Steel.
You’ll find something like 80,000 frames, each in OpenEXR half float files, in 4096 x 2160 pixels. This is 5 times more footage than used in the film, including unused shots, but mainly it’s because of long lead-in and lead-outs, and of course we’ve been cutting shots sharp.
