Magewell Pro Capture Dual DVI
Bring two sources into one PC slot, whether they are DVI, HDMI, VGA or component, and capture both at once.
- ✓Two DVI-I inputs captured at the same time as two channels, so one slot does the work of two cards
- ✓Each input takes DVI, HDMI 1.4a (via breakout cable), VGA (via adapter) or component (via breakout cable), so you can mix old and new sources
- ✓Input and capture up to 2048×2160 pixels; about 80 frames per second maximum at 1920×1080
- ✓Two DVI to VGA adapters and two DVI-I to HDMI + component breakout cables supplied, so there is nothing extra to order
- ✓Normal-profile (full-height) PCIe Gen2 x4 card, 115.9 × 91.29 mm, about 11.4 W maximum
- ✓Windows, Linux and macOS; built for continuous 24/7 operation

Magewell Pro Capture PCIe cards
The Pro Capture range of PCIe cards, section by section: HDMI, SDI, all-in-one, DVI and analogue, from single-channel cards to multi-input 4K models.
Watch on YouTubeAbout this product
A camera on HDMI and a computer on VGA, recorded together, usually means two cards or a box of converters. The Pro Capture Dual DVI does it in one slot. It is aimed at lecture rooms, control rooms and system builders who have to deal with digital and analogue equipment side by side. It is a two-channel HD PCIe capture card with two DVI-I sockets (the DVI type that carries both digital and analogue signals), and each one can take a DVI, HDMI, VGA or component source.
What goes in
- Two DVI-I inputs. Each accepts DVI 1.0 directly, HDMI 1.4a through the supplied breakout cable, VGA through the supplied DVI to VGA adapter, or component video (YPbPr, the three-cable analogue signal) through the breakout cable.
- Two independent channels. Each socket captures one of those signals at a time, and the two inputs work independently, so you can have HDMI on one while the other is VGA.
- Audio with HDMI. Sound embedded in an HDMI signal is captured along with the picture, with no separate audio lead. For a VGA, DVI or component source that needs sound, the single-channel Pro Capture DVI adds a 3.5 mm analogue audio input.
- Adapters in the box. Two DVI to VGA adapters and two DVI-I to HDMI + component breakout cables are supplied, one of each per input, so you can connect either kind of source on the day it arrives.
What your software receives
- Resolution. Input and capture go up to 2048×2160 pixels on each channel.
- Frame rate. Up to 144 frames per second, depending on resolution, with about 80 frames per second as the maximum at 1920×1080. Standard 1080p at 60 frames per second is comfortably within that.
- Processing on the card. Full 10-bit video processing with cropping, scaling, de-interlacing, aspect ratio conversion, colour format conversion, frame rate conversion and OSD composition. The computer receives the picture already in the size and format the software asked for, which saves processor time.
- More than one stream per input. Each input channel supports unlimited capture streams, so two programs can take the same source at different sizes.
- Low delay. Latency is 64 video lines, which keeps picture and presenter close together on a monitor.
Why choose it
- Two sources, one slot. For example a camera on HDMI and a computer on VGA, captured as two separate channels. That frees a slot for another card.
- Check your case. This is a normal-profile (full-height) card, 115.9 × 91.29 mm without the bracket, and it needs a full-height PCIe x4 slot or larger.
- Several cards in one PC. A rotary switch on the card sets a card number from 0 to F, so you can tell cards apart in a larger system.
- Built to stay on. The card is designed for continuous operation, 24 hours a day, 7 days a week. Maximum power draw is about 11.4 W, taken from the slot, so there is no extra power lead.
Setting it up
Fit the card, connect the source with the right adapter and install Magewell’s driver. Software sees the card through the standard capture interfaces of the operating system: DirectShow on Windows, V4L2 on Linux and AVCaptureSession on macOS. That lets you carry on with the software you know: it works with VLC, OBS, XSplit, vMix, VidBlaster and Wirecast among others. Supported systems are Windows 10, 11 and Server 2016 to 2025, Linux with kernel 2.6.35 or later, and Mac OS X 10.9 or later.
Where it sits in the range
If you have only one source, the single-channel Pro Capture DVI is a low-profile PCIe x1 card and adds a 3.5 mm analogue audio input. For composite video, see the Pro Capture Hexa CVBS. All the cards are on the Pro Capture range page.

Frequently Asked Questions
DVI, HDMI, VGA and component on each of the two inputs, so digital and analogue sources share one card. For composite (CVBS) sources, choose the Pro Capture Hexa CVBS.
Yes. It is a two-channel card, so the two DVI-I inputs are captured at once and can carry different signal types. Each individual input captures one source at a time.
With the supplied accessories: two DVI-I to HDMI + component breakout cables and two DVI to VGA connectors, one of each per input. There is nothing extra to buy.
It captures audio embedded in an HDMI signal, along with the picture. For VGA, DVI or component sources that need sound, the single-channel Pro Capture DVI adds a 3.5 mm analogue audio input.
2048×2160 pixels for input and capture, with about 80 frames per second as the maximum at 1920×1080.
A full-height PCI Express x4 slot (PCIe Gen2 x4) or larger. It is a normal-profile card, 115.9 × 91.29 mm without the bracket. For a low-profile chassis, see the single-channel Pro Capture DVI.
Windows 10, 11 and Server 2016 to 2025, Linux (kernel 2.6.35 and above) and Mac OS X 10.9 or later, through DirectShow, V4L2 and AVCaptureSession, so standard capture software sees the card.
