I-Movix is just finishing development of v3 sprintcam.
Based on a photron SA-2 camera, system is providing realtime HD-SDI output. Sensor is a 12bit CMOS of 2048 pixels wide, and speed can vary up to 2500fps.
Now, take a look at these sample shots, it's just amazing!
Source file download is available and recommended, as picture is far better than online flash encoding...
