Our portable capture cards are built with durable, full-sized connectors, and rugged metal enclosures, and include all the cables and adapters you need for video capture.

There are two types of Epiphan capture cards to suit your video capture requirements.

Av.io

Epiphan AV.io HD™, AV.io 4K™, and AV.io SDI™ use UVC drivers pre-installed on your computer, making it easy to capture video from your camera or other video source. Just connect your video source to one end and your computer to the other via USB and you’re ready to capture with any consumer or commercial encoding software.

Signature

Our Signature line of capture cards offer precise control over the captured frame size, frame rate, and color space, through custom drivers. You can use Epiphan Signature line frame grabbers with the included capture tool or any commercial or consumer encoding software, or write your own application with the included toolkit.
