Epiphan DVI2PCIe Duo PCIe x4 Video Capture Card with SDI and Dual-Link DVI Inputs

Product Overview

The Epiphan DVI2PCIe Duo is a low-profile PCIe x4 video capture card that brings lossless dual-channel video into a host computer from SDI and dual-link DVI sources, with HDMI and VGA supported through included adapters. Designed as a professional internal capture card for recording, streaming, and video analysis workstations, it delivers uncompressed video to third-party software on Windows, macOS, and Linux. It is built for AV professionals who need production-quality SDI and DVI capture directly inside a PC or rackmount system.

Product Description

The DVI2PCIe Duo captures lossless video from dual-link and single-link DVI, VGA, HDMI, and SDI sources, plus embedded audio from SDI and unencrypted HDMI signals. It supports resolutions up to 2048 x 2048, with frame rate scaling by resolution: Full HD 1080p captures at up to 60 fps, 1024 x 768 at up to 85 fps, and 2048 x 2048 at 20 fps. Because the card presents two independent capture channels, a single card can ingest two sources at once into recording, streaming, conferencing, or video analysis applications.

The card uses a low-profile short form factor and ships with a low-profile bracket for installation in 2U cases and compact chassis. It appears as a standard video device to third-party software, so it integrates with capture and production tools across all three major operating systems.

For workflows that need extended connectivity, pair it with the DVI2PCIe AV Kit. If you need USB capture instead of an internal card, compare the AV.io 4K and AV.io SDI+ in the Epiphan collection.

Frequently Asked Questions

What video sources can the DVI2PCIe Duo capture?

The card captures SDI and dual-link DVI natively, plus HDMI through the included adapter and VGA through the included DVI-to-VGA cable. It also captures embedded audio from SDI and unencrypted HDMI sources.

How does the card fit into an AV capture system?

The DVI2PCIe Duo installs in a PCIe x4 slot in a host PC or rackmount workstation and presents itself as a video device to capture, streaming, and recording software. Its two independent channels allow one card to ingest two sources at the same time.

What operating systems are supported?

Drivers are available for Windows, macOS, and Linux, in both 32-bit and 64-bit configurations, so the card works across common production and analysis environments.

Will it fit in a low-profile or 2U chassis?

Yes. The card uses a low-profile short form factor and ships with a low-profile bracket, making it suitable for 2U cases and compact systems.

What accessories extend its functionality?

The DVI2PCIe AV Kit adds extended input and audio connectivity for the DVI2PCIe Duo and is available in the Epiphan collection at Creation Networks.
