Video CaptureVideo from any analog source (composite or S-Video) can be captured as either still frame video images or motion video. Composite video inputs are provided as female RCA jacks, while S-Video uses a standard 4-pin DIN connector. The ImpactVCB comes with a VFW (Video for Windows) capture drivers for Windows 95 and Windows NT, and a WDM driver for use with Windows XP, Windows 98SE, Windows Me and Windows 2000. Typical capture rates range from 15 to 30 fps depending on system configuration.
Live Video DisplayThe ImpactVCB can display live video from NTSC or PAL video sources in a resizable window on the PC screen. The digitizing of the analog video signal is performed by hardware on the ImpactVCB, there by not slowing down the CPU. After video is digitized it is drawn by the ImpactVCB directly into the memory of the PC's Graphics card. This uses a feature of Windows called Direct Draw, and the ImpactVCB can be used with most Graphics cards which support Direct Draw 5 or higher. This technique is used on Windows 95, Windows 98, Windows ME, Windows 2000 and WindowsNT 4.0
