We have two categories of capture cards (versatile, portable USB capture cards) to meet your video capture needs: our AV.io family and our Signature line.

Our AV.io family of Epiphan AV.io HD™, Epiphan AV.io 4K™, and Epiphan AV.io SDI™ is the easiest way to capture video from your camera or any other source. It’s completely plug and play and uses UVC drivers already installed on your computer. Simply plug your video source to one side and the other side to the USB port on your computer. You’re ready to capture with any consumer or commercial encoding software or use with anything that works with USB cameras.

Our Signature line is the pro’s choice for ultimate configuration to capture video in any situation. Take advantage of Epiphan’s custom drivers to precisely control the captured frame size, frame rate and color space. Use the included capture tool, any commercial or consumer encoding software, or write your own software using the provided toolkit.

All our portable capture cards come with durable, full-sized connectors, rugged metal enclosures and all the cables or adapters you’ll need to start capturing right away. Deciding which video grabber you’ll want to use comes down to the input sources, resolutions and interfaces you need. Refer to the table below to compare USB capture cards.
