The easiest way to capture 4K video

Windows, Mac, and Linux operating systems will auto-detect the AV.io 4K capture card – no driver installation required.
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. Use your video at its original resolution or let AV.io 4K scale it to exactly what you need.
4K streaming anywhere, anytime
This compact frame grabber will fit in any kit, or even in your pocket. AV.io 4K is a USB video grabber, so its HDMI capture will work perfectly up to 4K on any computer with USB 3.0.
Ultra low latency
AV.io 4K captures HDMI video and audio as it happens. With just one to two frames of latency, you likely won’t notice 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 Wirecast, Skype, Adobe FMLE, QuickTime, VLC media player, and Windows Camera. Save captured content and easily upload it to video platforms like YouTube and Vimeo.
Tough as nails
With its rugged metal exterior, the AV.io 4K capture card will stand up to repeated, long-term use. Drop it down a flight of stairs, step on it – it’ll still work. The same enclosure has even been used in space!
