Buyer's Guide
Choosing a Capture Range
The Xtreme capture card family spans four ranges, and the right one depends on your source signal and how many channels you need on one card, not just on resolution.
DV
XtremeDV is the current-generation range, and the one to specify for any new 4K project. UHD2 and DP2 give you dual-channel true 4K60 4:4:4 over HDMI 2.0 or DisplayPort 1.2; SDI4 gives four channels of 3G-SDI for broadcast; HD4+ mixes two 4K and two HD channels on one card for medical and security applications with mixed-resolution sources.
AV
XtremeAV and XtremeRGB are earlier-generation ranges still in active use for HD, SD and analogue capture — SDI, DVI, VGA, Composite and Component. They're the right call when you're matching existing infrastructure that predates 4K, or where full 4K performance genuinely isn't needed and the lower cost matters.
LC
XtremeLC is the compact range — single or dual-channel HDMI/SDI on a smaller, lower-cost card, built for lecture capture, embedded systems and any build where PCIe slot space or budget is tight.
If you're still not sure, our Build My System tool will walk you through the choice alongside a compatible chassis and graphics card, or just get in touch with your source signal and channel count.
