Hi,
We are currently using ICImagingControl professional version 1.4 and have been feeding it with various capture devices.
We used the Video-to-firewire Converter Model DFG/1394-1e and initially found it to be satisfactory, until we started trying to capure the video image.
Although we tried using different codecs (DivX, Mpeg4, Windows movie etc) the real-time video picture ceases to be smooth and can be seen to 'jump'
At first we simply put this down to processing speed and tried various machines 2.4, 2.8 and finally 3.0 processors. The latter machine having 1GB memory and twin 160GB SATA hard drives, so it should handle it easily. Although the image has become smoother, there is still a noticable slowdown when capturing.
I was about to simply put it down to one of those things when I saw a Hauppage WinTV PVR device capturing video without hazzle - using an usb 1 cable. Since Firewire is masses faster than USB, I began to wonder.
We tried this device on my machine and although the 'Video-to-firewire Converter' worked fine, the WinTV PVY USB fails to be listed under device etc
So we tried a Adaptec AVC-11000 USB Video Capture device, this it found and gives us a colour picture, but it is of poor quality
So we tried a Belkin F5U228 USB Video Capture device, this gives a fantastic picture - its just black and white
However I have seen the Hauppage WinTV Go card mentioned on the forums. Unfortunatly, the software is required to work on laptops so PCI cards are out of the question.
Therefore, I was wondering if you can offer any ideas as to why different devices have different parameters available (I'm assuming its software driver related) and if you now of any other USB devices that will work ok
We have used a logitech web cam in the past, this works with no problem, but as the cameras used produce a composite video signal, they are no use
Any advice and suggestions would be greatfully received
