Thanks for the comments. I've actually seen that Mario Kart video before. A friend of mine is getting ready to teach a workshop on stop motion animation... fun stuff to ponder. At some point, I'll probably experiment with more "conventional," 24fps type videos.
Technique? Emm... shoot a lot. Just treat the sequence as you would photographing anything, just visualize every moment as 5 seconds rather than 1/200 and shoot in continuous mode. My camera (Canon 5d) shoots 3 fps. Don't let the camera be static. Incorporate the lens into the scene as a personality, and don't forget to focus in and out of scenes. They provide natural transitions. Shoot as shallow as possible, so you can quickly point the eye to the focus point, and if you go out of focus, remember basic design elements and use shape to your advantage.
I shot all of this on aperture-priority to maintain the 1.8 dof. Personal preference. Everything was shot as small JPG, since even that filesize is larger than a 1080 HD timeline. White balance as appropriate. Also, if you're shooting under florescent lights, keep your shutter speed under 1/200 or something. Experiment. A fast shutter picks up varying shades of lighting from the flickering lights. I learned that the hard way in parts of this video. Really, your ISO is the true exposure setting device.
I shot around 20,000 photos for this. That's... oh... 30 gigs? I'm not certain and the folder is on my workstation. You could batch certain things to the photos in Photoshop if you want. I sorted them in Bridge, and then created an AppleProRes 1080 30P timeline in Final Cut Pro and imported per 1000 images and saved them as sequences. I set the still frame duration to 00:00:00:06, or 5 frames a second. This means that they play back faster than they recorded, but hang on each image long enough to not have a fast motion feel. Except they do. Sorta.
Once finished, I nested each sequence into one master sequence. A quicker way would probably be to export each sequence as a Quicktime file, then reimport that and work on your edits from there. Otherwise, that's a lot of stills to manage.
At that point, it's simply video editing in Final Cut Pro. Treat everything as a video clip and create away. In the end, the video is almost 11 minutes long. 5 frames per second, times 60 seconds, times 11 = 3,300 photographs.
Have fun.
