The easiest way to capture 4K video
The plug and play Epiphan AV.io 4K™ capture card is auto-detected by Windows, Mac and Linux operating systems. To capture HDMI video sources, simply connect the included cables from your video source to AV.io 4K then connect AV.io 4K to your computer via USB.
Wide range of resolutions
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.
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”
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.
Broad application support
AV.io 4K works seamlessly with your favorite paid or free applications such as Zoom, Wirecast, OBS, VLC media player, QuickTime, and Windows Camera. Save captured content and easily upload it to video platforms like YouTube and Vimeo.
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!
What’s in the box?
AV.io 4K comes with everything you need to capture 4K video.
