Magewell Ultra Stream HDMI - Streaming Encoder

Magewell Ultra Stream HDMI - Streaming Encoder


The Magewell Ultra Stream HDMI is a single-channel HDMI streaming encoder that can encode streams up to 1080p at 60fps for Content Distribution Networks (CDNs) such as YouTube Live, Facebook Live and Twitch, or RTMP servers. At the same time, you can record the stream on your mobile device or on a USB drive connected to the front panel USB 2.0 port. All controls are located in the mobile app for iOS and Android. The buttons to start/stop streaming and recording are located on the unit itself.

The HDMI input supports UHD and DCI 4K signals up to 60fps. The HDMI loop-through output displays the input signal without affecting resolution. Internally, the Ultra Stream HDMI will downscale it appropriately for streaming and/or recording. It has a 3.5mm input jack for connecting a microphone and another 3.5mm jack for headphone monitoring.
