An alternative (not for the timid) would be to use a fairly robust notebook (Windows, Mac, or Linux) running OBS Studio with a USB 3.0 (minimum) video capture device, such as this one* or this one* on Amazon. (Not recommendations, just examples.)

Experimenting with OBS and wondering if you had an OBS profile that contained the settings you used for output, especially to ensure max bitrate isn't exceeded? I am ok with "not for timid" statement.

Thanks.

Greetings. I split this off the other topic so we could discuss OBS in more detail. I included more info than you requested for the benefit of those new to using the free Open Broadcaster Software (OBS) with the church's Meetinghouse Webcast (MWC) 3.0.

First of all, in OBS Settings --> Output , select Service as Custom.... From the MWC Event Setup --> Other page (only available for upcoming events), copy/paste the RTMP URL and Stream Name , to the OBS Server and Stream Key fields. Don't check Use authentication.

In OBS Settings --> Output you can keep the Output Mode at Simple. Set Video Bitrate to no more than 2200 kbps (this limit may be higher real soon :) ). For the Encoder, select Hardware (NVENC) if you have an nVidia encoder equipped video card*. If not, select Software x264. Set Audio Bitrate to either 64 or 96.

*To see if your nVidia card or mobile processor has an encoder/decoder chip, go to Wikipedia's List of Nvidia graphics processing units, select your video card or mobile video processor, and record the "Code Name". (Also available with CPU-Z or similar utility.) Compare that with this Nvidia NVENC wikipedia page to see if it's on the list. While some cards as early 2011 supported NVENC, the implementation was not nearly as good as later cards and you might get better results just using software encoding.
So we can better help you, please edit your Profile to include your general location.

Here's a quick setup draft we created for OBS. I hope it helps. This just provides the basic setup for OBS and does not get into some of the more advanced features.

Appreciate the document. I don't know if I would have been able to figure out the keyframe interval. It worked tonight in a quick test. I have a 5 Mbps upload connection in this Stake Center building, and set it to 500 Kbps for testing. Broadcast overview showed 558/500 kpbs for current/target encode rate.

Thanks again.
