This hand-size grabber fits in any kit, or even your pocket, in a pinch. It is a USB video grabber, so its HDMI capture works perfectly up to 4K on any computer with USB 3.0.

Ultra low latency

Ultra low latency

AV.io 4K captures video and audio as it happens. Your video capture software gets the frames so fast (just 1 to 2 frames of latency), you may even find it difficult to see any lag at all.

“AV.io 4K shines in this department also, delivering near-zero lag. Having a side-by-side comparison demonstrates how lag-free the streaming functionality actually is, with the human eye you’ll struggle to identify any latency”

David Mitchelson, Review on vortez.net

Tough as nails

AV.io 4K capture card is perfect for reliable and repeated long-term use. It uses the same metal exterior as all other Epiphan video grabbers, which means that you could drop it down a flight of stairs and step on it, and it would still work. The same enclosure has even been used in space!
