If you’ve ever tried recording in 4K, you know that recording uncompressed 4K needs some heavy guns. The most common solution is an Atomos monitor/recorder, and those are usually $1,300 and up. If you are shooting HD there are many capture devices out there, but for 4K… not so much.
Epiphan wants to take a bite out of this cake and they launched the AV.io 4K. AV.io 4K is a small, pocket-sized capture device that conencts to your camera’s HDMI out on the input side, and to your computer’s USB on the output side. (most 4K capture devices use thunderbolt). This is an early bird, I guess, for a flood of 4K capture devices, but they’re curently one of the only options I’ve seen. Best, an AV.io 4K is around only $430 vs. the olmost quadrule Atomos.
