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 79% to 96% 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
