Four Channel HDMI Capture Card

  • Four independent HDMI 2.0 capture channels
  • Embedded Audio
  • EMS unified Windows® and Linux® driver


The XtremeDV-HD4+ has four channels of HDMI 1.4, two supporting 297MHz (3840×2160 at 60 fps) and two supporting 165 MHz (1920×1080 at 60 fps), all operating independently of each other. This enables four separate four video sources to be captured and controlled simultaneously. The card also has embedded audio support across all four channels. The XtremeDV-HD4+ is shipped with adapter cables for either HDMI or DVI.
