USB host controllers When capturing 4K resolutions we recommend using a computer with an Intel USB host controller (this is the most common type) to achieve the best results. With other USB host controllers such as ASM, AMD, VIA, Renesas, Eltron, Fresco and TI, capture will be at 96% to 79% of the expected frame rate.
HDMI Audio Input Up to 96 kHz sampling rates
Audio output 16-bit 48 kHz stereo sampling rates
Capture latency Near-zero. However, third-party applications may contribute capture delay
HDCP High-bandwidth digital content protection (HDCP) protected content cannot be captured
LED LED indicates the status of the AV.io 4K
Dimensions 3.54″ × 2.36″ × 0.91″, (90 mm × 60 mm × 23 mm)
1 For DCI 4K, actual frame rate limited to 24 fps for NV12/I420 and 15 fps for YUY2.
