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.

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.

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
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!

USB host controllers: For best results when capturing in 4K, use a computer with an Intel USB host controller (the most common type). Other USB host controllers such as ASM, AMD, VIA, Renesas, Eltron, Fresco, and TI, will capture at 96% to 79% of expected frame rates.
HDMI audio input: Up to 96 kHz sampling rates
Audio output: 16-bit 48 kHz stereo sampling rates
Capture latency: Near-zero, though third-party applications can contribute to capture delay
HDCP: High-bandwidth digital content protection (HDCP); protected content cannot be captured
LED: LED indicates capture card status
