  • Four lane PCIe lane bus, Net 1.6 GB/s total capture bandwidth
  • Triple channel PCI Express capture card
  • Direct DMA to graphics memory of third party graphics cards
  • All standard features of the XtremeAV range of capture cards
  • Driver support included within the EMS unified Windows driver
  • Driver support included with the EMS unified Linux driver (NOTE: Check Linux specific features with Sales)



A capture card with three independent channels of video capture for 3G SDI, DVI and Composite video, with full analogue and digital support.

The XtremeAV-SDI is a four lane PCI Express card with three video capture inputs – two supporting HD capture and a third supporting SD composite video, these three independent video channels can be captured simultaneously. The XtremeAV-SDI also adds multiple channels of audio capture, which can be synchronized in software using timestamping with all video capture channels.

The half length full height card features a full mechanical 16 lane connector with notches which will enable it to fit four, eight and 16 lane motherboard connectors.

The XtremeAV-SDI also adds embedded audio capture from SDI signal, which can be synchronized with the respective video channel. This card provides balanced and unbalanced analogue capture, through an optional audio module (the EMS AM2)

This capture card provides a single flexible card solution for areas such as medical, lecture capture, web casting and video conferencing.


The DVI High Definition channel supports HDMI, DVI, RGB and Analog Component (YPbPr) input via a DVI-I connector, at resolutions up to 4096 x 4096 pixels and supports 1080p (1920 x 1080) at 6o frames per second. 

The Standard Definition channel is input as composite video on a single RCA connector and can auto-detect  between PAL, NTSC and SECAM formats.

The SDI channel supports SD-SDI, HD-SDI and 3G-SDI (including 2K Digital Film Resolution modes). The XtremeAV-SDI also adds embedded HDMI and SDI audio capture, which can be perfectly synchronised with either video capture channel.


DirectShow drivers for WDM Streaming driver supports the following applications, to encode, record and stream video over networks or the Internet:

• Microsoft Media Encoder®
• VirtualDub
• Any other DirectShow encoding software

For streaming applications, the XtremeAV-SDI can be used with Windows Media Encoder to compress and stream captured video. To replay the video, use Windows® Media
Player. Any application compatible with Windows® DirectShow technology can use the VisionAV-SDI due to it built-in WDM support.


Input and output connection via the Audio Breakout cable which is supplied with the optional AM2 audio module attached to a 15 pin high density D-type connector on the Audio Module. The physical connections comprise of:

• Left and right balanced audio input on female XLR jacks • Left and right unbalanced line inputs on female RCA connectors
• Left and right unbalanced line outputs on female RCA connectors for direct passthrough of selected analog input

Flexible input/output mixing capabilities.
Supports audio capture at popular sample rates from 44.1 to
96 ksamples/s at 16 bits/sample.
Playback and mixing of Analog, embedded HDMI and SDI
