This is a 2009 experiment in the perception of digital video. Two sample videos were made each 4 seconds long, each as-if 200×150 pixels.  These should be thought of as small portions of a larger video. In one sample the pixels stay put, in the other they jump around (all together).

The experiment is available in two forms:

jumpy_pixel_experiment.zip has size just 27 MB for quick download.  It contains the videos as 2000×1500 .mov files in Apple codec "None".  You'll need a system with Quicktime able to display a 1800 Mb/s video stream.  I suggest using a RAM disk.
Download it from: http://www.mediafire.com/download/7u42a5n62nj0zkh/jumpy_pixel_experiment.zip

jumpy_pixel_experiment_prhq.zip has size 150 MB.  It contains the videos as 2000×1500 .mov files in codec ProRes 422 HQ.  Compared to the first form, the system requirements are much relaxed, but the download is much larger.
Download it from: http://www.mediafire.com/download/pbpqzstnqm9tb2h/jumpy_pixel_experiment_prhq.zip

For either form you'll need a monitor having at least 2000×1500 pixels. 

Included in the download is jumpyreport.pdf which describes the experiment in some detail.  Please read the first page of the report before playing the videos.
