OSEE GOSTREAM DUET Overview

Setup your livestreams from anywhere using a variety of HDMI, USB, or SDI equipment with the GoStream Duet SDI/HDMI/NDI|HX Live Stream Video Mixer/Switcher/Recorder from OSEE. The portable Duet provides SDI, HDMI, USB-C, and NDI|HX connectivity, allowing wide compatibility with various cameras, media players, and video devices. The switcher features four HDMI inputs, four SDI inputs, NDI input via Ethernet, and one USB-C input that interface with two HDMI outputs and one USB-C output.

Both the input and output ports support up to 1080p60 video. An SD card slot allows for direct recording and playback to a connected monitor without requiring a separate PC, and the USB-C output allows you to record to external SSD media. Live streaming is available via RTMP and IP simultaneously to up to three platforms such as YouTube or Twitch, and NDI|HX streaming is also available with the latest firmware.

Streamline Your Livestream Production
The GoStream Duet features a comprehensive, tactile control panel with numerous buttons, PVW and PGM select buttons, knobs, and a fader. It also features recording to SD card and external USB SSD, which also support the playback function, reducing the number of required devices needed to facilitate your livestream.
Supports Three Simultaneous Streams
Livestream to three different platforms such as YouTube or Twitch simultaneously using the integrated Ethernet port on the GoStream. Connect a USB webcam to the USB-C input and output that feed via OBS, VMix, or Zoom using the USB-C output port.
Output up to Five Channels
Select up to five video input sources from the SD card, SSD, HDMI, SDI, USB, or NDI|HX inputs, such as cameras, streams, switchers, and UVC sources, and output them to a monitor or projector for simultaneous presentation, or connect an optional Stream Deck or built-in WebGUI.
Built-In Audio Mixer
An internal audio mixer supports seven channels of embedded and input audio sources, with audio sources coming from the SDI and HDMI inputs, one from the AUX input, and two from dedicated 3.5mm TRS microphone ports. Mix the inputs into the program output using the On/Off or AFV controls on the switcher and adjust parameters like gain, balance, and fade. Monitor audio from a selected source using the headphone input.
Utilize up to Nine Effects
The GoStream Duet supports nine special effects including Super Source, upstream keyers, downstream keyers, Chroma keyers, transitions, and a still image generator. Craft visually appealing, multi-layered effects tailored to your production. Use the eight Macro Memories to record specific composition functions and set them as custom presets for efficient recall.

Got switcher working, but not software

By David
Rated 4 out of 5
Date: 2025-12-24

Overall, I'm pleased with this switcher, especially that it has both SDI and HDMI inputs, onboard menus (via the multiview output), a headphone out, and all the basic capabilities you'd expect. We've used ATEM mini pros before, but I think this one will fit our needs better and works great so far. I had trouble setting it up at first because I didn't have an HDMI display handy to view the multi-view output with the menu, and the software didn't work for me, on a Windows 10 PC (and still doesn't work...). Fortunately my output #2 was already set to multi-view, and I plugged it into an HDMI capture card on my PC, and was able to use that. The menu was initially in Japanese, but thanks to google translate, I was able to get it back to English. Once I could see the menu, and had the menu in English, I was able to get everything else working (like turning the mic inputs on, upgrading firmware, etc.). I was able to find some youtube videos that helped with things. So it was a little bumpy getting going, and I would still like to have the software working, but am happy with the switcher itself at least.

Is the SD card slot the only option for media playback or can you load content using an external SSD and the USB-C port?

The SD card slot on the OSEE GoStream Duet SDI/HDMI/NDI|HX Live Stream Video Mixer/Switcher/Recorder would be the only option for playing content. The USB-C port on the device is for a UVC output stream only.
