SmartSentry has been successfully tested and performs well with Windows 2000
Under certain conditions, changing the Video format while using a Trigger Zone may require SmartSentry to be ended and restarted to redefine the trigger window, this is a known issue and will be resolved in future releases.
Some drivers written for graphics cards with integrated video capture hardware do not fully observe the Microsoft Video For Windows programming guidelines. This results in a 'Divide by zero' error being reported when trying to set a trigger zone with SmartSentry.
The following formats listed in order of performance chosen from the 'Configuration . Video Format' menu option : All image dimensions using 24-bit image format; All image dimensions using 32-bit image format; All image dimensions using 15-bit image format.
Capture performance is a function of Disk I/O, CPU speed, and the choice of CODEC. It is also important to be aware that the 'Configuration' -> 'Video Format' setting is largely independent of the choice of desktop display setting in use. That means that in many cases you can have a low resolution desktop display, but still capture at a high resolution.
Disk I/O: In general SCSI drives perform better than IDE drives for video capture.
CPU speed: Higher speed CPU systems support higher CODEC performance, which may sometimes compensate for poor disk performance.
Choice of CODEC: Capture performance may vary widely with different CODECs depending on the way you use SmartSentry. As a general rule, the CODEC that performs best on your system for movie capture will also perform best with SmartSentry. Some other points that are worth noting:
The following CODEC's chosen from the 'Configuration . Compression' menu option:
The settings below have resulted in good capture performance and provided good quality avi output
