Using Qualisys video with External timebase

All Qualisys video cameras can be used with External timebase, but only if the video capture rate is a divisor of the marker capture rate. The video capture rate also needs to be an integer so you cannot use any divisor on the marker capture rate. The presets that can be used are activated automatically for the current marker capture rate. For example, if the marker capture rate is 200 Hz, you can capture video in 200, 100, 50, 40, 25 and 20 Hz. These are the divisors 1, 2, 4, 5, 8, and 10.
