Re: video capture question



Mark,

Depends on what you want to do. I've used analog cameras with PCI capture
cards, a digital video camera with an IEEE 1394 card, and USB cameras. My
preference, for video capture and analysis, is an analog camera with a PCI
card. The Winnov Videum board is good and runs on Windows 95, 98, NT 4 and
2000. The digital video camera with IEEE 1394 may be better with still shots
or creating home movies. However, for motion, I found my digital video
camera and IEEE 1394 board recorded a 720X480 image size, but this included
both fields in each frame. For faster motion, the two fields are quite
noticeable when you are viewing individual frames for analysis and I needed
to reduce the image to 360X240 to get rid of one field. USB cameras are
limited by bandwidth. You may need to trade of FPS with image size to
eliminate dropped frames when using a USB camera.

appreciate insight into what the current best buy is in this area. In
particular, is there any advantage in having a digital video camera - can
one video files directly via a usb port with such a device?
