Used a series of special programs to slow down "Let it Go" from Disney's "Frozen" down to 1/17th of its original speed. As the human eye is much better at figuring out what's happening between frames than a computer, there is some artifacting("expoding", drifting pixels) between the original frames(which at this speed only occur every 0.68 seconds, rather than the normal 0.041(24 fps). Basically, if a part of the original image moves too fast, to a position not close to where it was in the previous frame...it "explodes".
However, that said, some of the motion is surprisingly well smoothed out.
As for the sound, like the video, we're taking something that was designed to be good at normal speed, and stretching it to a fraction of that. When you slow down audio normally, it drops in pitch. To keep it smooth and and in-pitch, the program I used for this copies the audio over itself, and uses a bunch of fancy math to keep it smooth. Basically, it gets echo-y, less clear, and somewhat trippy sounding.
I may be able to reduce the video artifacts some, but it took my medium-power computer 15 hours to render what you see here, so this is what we got so far. Redoing it on 1080p with tweaked settings will probably take quite a while.
