The Osee Gostream Duet is a 4/5 channel vision mixer designed for live streaming. It is very similar in many ways to the Blackmagic Atem Mini's but also different in some key areas. In this live stream I'm going to take a look at some of those differences and explain why I've chosen the Gostream Duet for my mobile live production system build.
The Gostream Duet supports 4 HDMI or SDI inputs plus a further external source which can be a UVC camera via USB-C or an NDI camera over the connected network. It also has 2 HDMI outputs and these can be configured as a multiviewer output, the switched programme or preview outputs or any of the input sources.
