I just went looking for this page, but it is no longer available. I'm mainly interested in a couple of the items you had in a list of equipment. Any chance you could publish it again?
Thanks!

Fixed. We just updated the website this week, looks like this page didn't get transferred over.
Be careful when ordering any of these lesser-known brand cameras, such as SMTAV, Zowietek, Prisual, AVKANS, SZOOMSY, FoMaKo, TONGVEO, Vikery, etc. Some of their models support full NDI (125~200Mbs for 1080p60), while other models only support NDI|HX (12~22Mbs for 1080p60). NDI|HX can have as much as 0.25 - 0.5s lag time. This can be corrected in programs like OBS, but forum users say the lag time isn't constant, which really messes things up.
Can you give me a rundown of how you use NDI? (Or perhaps start a different post?) I've largely ignored NDI and stuck with tried and true direct HDMI for video and a serial cable for PTZ control. I started to go down the NDI road, but didn't like that it was a proprietary standard, and NDI / OBS support was lackluster, at best.Mikerowaved wrote: ↑Sun Jan 15, 2023 3:50 am BTW, uncompressed 1080p60 over SDI (coax) clocks in just under 3Gbs, so to compress that down to ~150Mbs (NDI), or even 20Mbs (NDI|HX) and still have a pretty good looking picture at the end of the day is quite an accomplishment. NDI|HX2, and now NDI|HX3 promise better quality with lower lag time. That might be an option for some.
We're currently using the church's setup with their HDMI extenders. However, I've used NDI quite a bit for other events I've webcasted. One big advantage is if the camera supports POE and NDI, you only need to run ONE Cat5e/Cat6 cable to it. I found a dedicated cable is best, but 1 or 2 cameras can be run on an existing gigabit LAN.
Ah, that does sound nice, three cables get reduced to one cable.Mikerowaved wrote: ↑Mon Jan 16, 2023 3:11 pmWith that one cable, you can power the camera, receive a nice video stream, control the PTZ operations, and get into the camera's built-in setup/configuration page(s).
Yes, OBS has camera control plugins, but their *NDI* plugins struggle. I use the OBS PTZ plugin by glikely and love it, I've had it work with three different brands of cameras without an issue. The OBS NDI plugin on the other hand I ran three issues: 1) the main NDI plugin was languishing without updates, 2) it about doubled the CPU computational requirements on some laptops that didn't have any CPU left to give, 3) people routinely complained that the plugin's audio/video desynced and progressively drifted off more and more over time with no fix available.OBS natively supports NDI quite well and can do camera control with one of several plugins available.
