Hello all,
I have to determine what cameras and capture cards are best for video tracking...
Preferably, i would like them to work with as many platforms as possible (OSX, windows and Linux) and this are the constraints:
capture cards: the least latency possible. I have tried some digitizers that used compressed firewire and they are too slow (too much latency). others like the turtle beach are uncompressed firewire and seem to be faster, however, so far cheap PCI cards seem to be faster for me, but the restriction there is that it has to use a slot in a computer and most are for windows only.
Video Cameras: good color resolution, option to turn off auto-iris (and preferably more than 30 fps). I have tried a canon 3 ccd that gives good color resolution but only 30 fps. I also tried some CCTV cameras, but they have autoiris and bad color resolution (only composite video out). I briefly tried fire-i and they seemed to have low latency through their firewire out. I think you can hook them in series too which is also great unless latency increases.
anyway, if anyone can share their experiences i would be very greatful,
thanks in advance,
Jaime
