1080p 60fps


Choose your resolution

AV.io 4K captures resolutions up to 4096×2160, with 4K UHD video streaming at 30 fps and 1080p at 60 fps. Choose to use your video at its original resolution or let AV.io scale it for you to exactly what you need.

4K streaming anywhere, anytime

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.

1080p 60fps


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


Crystal clear audio

AV.io 4K captures PCM audio over HDMI™ at up to 24-bit 96 kHz. The two-channel stereo audio output has automatic resampling at 48 kHz and encodes in 16-bit.

Application support

Works seamlessly with your favorite paid or free applications such as Wirecast, Skype, Adobe FMLE, QuickTime, VLC media player and Windows Camera. Save captured content and upload to video platforms such as YouTube, Vimeo and others with ease.

1080p 60fps


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!
