The Osprey is quite versatile and reliable. We have purchased dozens of the G1 & G2 encoders for use throughout numerous facilities in our extensive network. Our primary use is for multicasting, but we also do a number of unicasts and YouTube streams.
Osprey tech support is so helpful and knowledgeable, which is another huge selling point.
We have used numerous other manufacturers products (HaiVision, Evertz, Ensemble Design, and Lynx). All of them work fine but Osprey offered the best quality and reliability for the price.

Bought this and its matching rx. They seem pretty good. You can select different definitions, FHD, HD, SD, and then can assign them to the 3 types, and allocate bit rates for each. Eg you can select HD, send that to SD and a bit rate of 800 and FHD to HD and a bit rate of 2000 etc. It then selects the resolution type, eg 720P. The only limitation I find a bit strange is that the full range of resolutions, are not available all the time. They vary what is available depending on the Hz, 50Hz or 60Hz of the incoming HDMI. I am using 60Hz, and this does not have 1080i, but if I was using 50Hz, then 1080i would be included.
60Hz has 480i, 480P, 720P, 1080P.
50Hz has 576i, 576P, 720P, 1080P, 1080i.
The other strange thing I notice is that if I select a bit rate of 800Kbps, and then monitor the link at the IP level, it seems to be using about 3.5Mbps.
However, for quality and ease of use, these seem to be great devices.

Use these to send my program video to my announcers for sports productions. My production truck is all IP so I just choose my NDI Program source and plug in an HDMI cable to their monitors and perfect easy setup. And, now I can send multiple things to the monitor just by simply choosing a different NDI source and a quick switch is done. No routing needed.

These units are ideal for instant connect up and they work. You can customise the bit rate and it keeps the video smooth. One TX can feed many RX.

Using this to decode an NDI source to a projector in Church services with live stream. We previously were sending the Presentation Laptops screen to the OBS computer via NDI, and used a separate proprietary wireless video feed to the main projector. Got this so we can use the same NDI source for both and eliminate the wireless projector feed.
It is working well. One thing to be aware of: the projector will display will go blank in a couple of seconds if there is no video and audio activity when using NDI Screen Capture as the source. This can be an issue during power points with static screens. You can set the decoder to keep the last thing displayed on the screen or allow it to go blank. I prefer it to go blank so I know something is wrong right away. You can also resolve by making sure the NDI Screen Capture is using an active audio source (like the microphone).
This decoder has been reliable and is reasonably priced. Perhaps other decoders won't have the inactivity issue but they are also more expensive. This has not been a show stopper for us.
