The XtremeDV-SDI4 is a PCIe Gen 3 capture card with four 3G-SDI inputs, each capturing up to 1080p60. Every channel is timestamped in hardware so that multiple feeds can be kept in step.

Each BNC input captures up to 1920×1080 at 60Hz (2.97 Gbps), from 480i and 576i through 720p, 1080i, 1080p, 1080psF and 2K (2048×1080). The format is detected automatically from the SDI payload identifier, and every channel is timestamped in hardware so larger surfaces can be captured and stitched.

Inputs

3G-SDI: Four BNC inputs, each up to 1080p60, at 23.98, 24, 25, 29.97, 30, 50, 59.94 or 60Hz.
Formats: 480i, 576i, 720p, 1080i, 1080p, 1080psF and 2048×1080p/psF, to SMPTE ST-259, 292, 424, 425 and related standards.
Audio: Multi-channel embedded audio.

Outputs

To the computer: An eight-lane PCIe Gen 3 interface with a 768MB frame buffer.
Formats: RGB 4:4:4 and YUV 4:2:2 / 4:4:4, with alpha.
Timestamps: Each channel is hardware-timestamped, so four feeds can be stitched into one larger surface.

Applications

Broadcast and live production: Four camera or router feeds into one recording or switching PC.
Video walls: Stitched, synchronised SDI surfaces in a VSN system.
Command and control: Multiple SDI camera feeds captured on one card.
Standalone: Many customers run it in a single production PC with no wall controller.

Installation and software

The card: PCIe x8, 110 × 177mm including the heat sink.
Drivers: The EMS unified driver covers Windows 10, Windows 11, Windows Server 2019 and 2022, and Linux.
Software: DirectShow (WDM streaming), for Microsoft Media Encoder, VLC, VirtualDub and other DirectShow software.

How many SDI inputs does it have?

Four independent 3G-SDI inputs on BNC, each up to 1920×1080 at 60Hz.

Does it capture embedded audio?

Yes. Multi-channel embedded audio is supported.

Can the four feeds be kept in sync?

Each channel is hardware-timestamped, which allows the feeds to be stitched into a single larger surface.

Do I need a video wall controller?

No. It works in any PC with a free PCIe x8 (or x16) slot, and is often used for multi-camera recording and switching. It can also go in a VSN chassis.

What warranty does it have?

A standard 3-year warranty, with a 5-year extended warranty available.
