In November 2016, we announced new 4K editions of the Livestream Studio HD51 and HD550 units. In the video below, Livestream Founder Max Haot discusses the capabilities of these new machines.
Please note that as of now, these units are able to record and output live video but they cannot currently stream in 4K. We plan to release this feature soon. Max addresses this at around the 23:00 mark in the below video.
