GoStream switch beats the competitors' with features, price and customer service

GoStream switch beats the competitors' with features, price and customer service
I purchased the GoStream Duet video switcher to record and stream a podcast that my friend does, and it has been working well. It is capable of doing so much that I really haven't had time to use all the different functions yet. I did the first test of the podcast using 3 iPhones as cameras with HDMI adapters and the unit worked well. I ran audio from a Tascam Mixcast 4 into the GoStream without issues. I was able to adjust the slight audio delay in the GoStream menu system. We will probably upgrade to PTZ cameras at some point with NDI/HX3 and/or SDI capability, which the GoStream can also handle besides HDMI. (Only one camera can be NDI/HX3.) I choose the Duet model over the basic GoStream model because it includes a (needed) cooling fan, and includes the NDI license (which costs extra in the basic model). They also shifted the memory card slot to the left front side of the unit to make room for the internal fan. The GoStream has the capability to stream to 3 services at the same time, although you'd need serious bandwidth to do that, and most people wouldn't require that many streams at the same time. I also like the fact that it has many features that broadcast switchers I've used professionally have: a preview and program bus, a T-bar and a Multiview output. You can do several types of keying, store stills and video and save macros. There's free software to use the control panel display on a computer, and Companion software is available if you want to use a Elgato Stream Deck to trigger macros (like camera shots and graphics for example). For the price this has everything and more that I could ask for. The company, OSEE has a dedicated Facebook page where there is an excellent FAQ file covering just about any question you could think of, and the developers monitor the page constantly. If you have a question or concern, you can get quick help there from both the company and other users worldwide. Recommended!

    Live production game changer!

    Reviewed in the United States on August 8, 2025

    I just used this for the first time as part of a mini convention that I do AV for every month and wow! It took care of nearly all my unresolved pain points.

    The multiview output is super convenient for preparing source selection without interrupting what's currently being displayed (PGM), whether that be a video input or an image/video loaded on the device. Those files can be uploaded from the SD card or from a computer attached via the USB-C port.

    We can have up to a dozen different speakers, each with their own laptop. Previously, they would have no idea if they were properly outputing a good signal prior to cutover. Now I'm able to run a signal (PVW) to a mini monitor mounted on their mic stand that shows what they're sending. I can see it as well on my multiview monitor.

    So, between the PVW and multiview there isn't another HDMI output available for PGM, but I have OBS connected to one of the USB-C connections and send the output from my laptop to an HDMI transmitter to display on our projector.

    On the subject of OBS, this device integrates flawlessly! I used to do video capture with an Elgato HD60 S+ on my M1 MacBook Pro, which was terrible. The video mostly worked fine, but the audio was tempermental to say the least. If a speaker needed to send audio over HDMI it would require opening and closing OBS several times while unplugging and plugging in the capture card. Then it might work. In testing, this unit has worked every time even when switching sources.

    Of note, OBS has crashed a few of times since adding the GoStream to my setup, but both OBS and macOS updated during that time as well, so it might not have anything to do with the Duet.

    I've barely scratched the surface of what this thing is capable of and am truly excited to see what else I can do with it.

    I can't imagine doing a live event again without the osee GoStream Duet!

    Best streaming switcher I own.

    Reviewed in the United States on August 31, 2025

    Verified Purchase

    Work in broadcast, we use the tricaster as our main switch and for location switching we used black magic, I saw this being advertised and bought it to try it. Best money I've spent, not only does it not need to be connected to a computer to get the most of it but I also have VTR playback and graphics via SD card and can record direct to a ssd 2 programmable outputs not including the usb-c out and sdi or hdmi inputs, which is great for me since a lot of our broadcast cameras are sdi only.

    Easy to use interface, great build quality, if you are in the air about a portable switcher, give this little beastie a try, don't think you will regret it.

    A great (and possibly better) alternative to the BM ATEM Mini!

    Reviewed in the United States on May 27, 2025

    Verified Purchase

    Great device with an even greater superpower – it has 4 inputs and accepts any combination of HDMI and SDI inputs! Currently, I'm running 1 SDI camera, 1 HDMI camera and 1 laptop to it. Just about everything is working great! I've upgraded the firmware, however, I still haven't been able to get NDI through the unit to any of our church audience screens. The manual says, "update to the latest firmware and you get a free NDI license". Problem is, I haven't found a way to verify that the license has been applied to the device. It seems there are a few things lost in translation when it comes to the user guide, but I'm sure I'll figure it out eventually. I haven't tested streaming directly from the unit (to YouTube, for instance) but every other function seems to be working just fine so, I'm very happy with the purchase.
