Epiphan claims the AV.io SDI is a “simple” SDI capture card as it doesn’t need any special drivers installed on your computer – plug it in to your USB port and out comes SDI. Windows, Mac and Linux operating systems automatically detect AV.io SDI. It’s also compatible with Skype, Wirecast and QuickTime.
The AV.io SDI captures uncompressed Full HD video (1080p) at 60fps and it’s small enough to fit in the palm of your hand (in an aluminum enclosure).
