Last time I have recorded using 3 Pseye cameras in half circle with 25 fps and the   Tracking results were pretty acceptable.Yesterday I have used 6 pseyes @ 50 fps .no drop frames at all.Calibration was very good.But comparatively the tracking results produce more jitter compare to my 3cameras 25fps results.

Is there a possibility like more cameras and more frame rates will add errors ?

For info: calibration done at 30fps and action video at 50fps.

Actually , what I'm capturing is a person standing and giving speech.some times folding hands to chest mostly waving hands in the air.Pls suggest the 6 camera configuration like half / full circle , optimum cam heights and acceptable fps for this scenario.I need to do the final shoot by This Saturday.
