Videum Duo Xpress

The Gold Standard in Video Capture Technology

Buy Now


Videum Duo Xpress is part of Winnov’s new line of super-fast, super-powerful video capture cards built on the PCI Express architecture. This two channel audio/ video capture card is essentially two AV capture cards in one. Simultaneously, you can capture two different AV source pairs or capture the same sources twice. There are many cases where this is desirable. For IPTV applications, you may want one system to archive and/or broadcast two different videos in the same system. Also, you may want to broadcast the same video with two different qualities. It fits into any PCI Express slot, regardless of lanes.


Videum DirectShow Driver 3.8 is required for all Videum Xpress cards with audio features manufactured after December 2012. Please contact if an earlier driver version must be used with new cards. Affected products are: Videum 4100 Xpress / Videum 4400 AV Xpress / Videum Duo Xpress / Videum Quattro Xpress



Register your Videum video capture card to extend the product warranty period to 15 months from the date of purchase at no additional cost.
