Yes, some progress. What you see here are two 2015 Dell Precision 5810's working in tandem as Primary and Secondary Panopto Remote Recorders. There are more than a few mistakes here, but you get the idea.

One of the 5810s is inputting the HDMI output of a Macbook Pro running Monterey 12.3.1 thru a Magewell USB3 to HDMI adaptor.

The same 5810 is taking the HDMI output of a Canon video camera and the audio feed from a Sennheiser lavalier mike into a pretty sketchy HDMI to USB3 or USB-C Video capture dongle purchased on a lark by the notorious Sam Burns, thinking we might make something work with it. He was right, again.

You can also see the desktop and Task Manager running on this 5810, notice it's using 4% of 64 Gb of RAM, but 90% of the processor.

So that's the Primary Panopto Remote Recorder, video from a faculty laptop, audio and video from a Canon video camera, and the desktop of the Remote Recorder.

The Secondary Panopto Remote Recorder is another 5810 with 32 Gb of RAM, much of which it doesn't need. It's taking the input from a Logitech c930 webcam via USB3, but no audio. It's also sending it's desktop running Task Manager to monitor the computer. Next test will split the HDMI inputs across the two computers to try to load balance.

Finally, Panopto running on an iPhone can remote control the Remote Recorders, and it's really handy to monitor your audio and video going into the units, which are headless and setup as Panopto Remote Recorders, so nothing else is on them besides Windows and Panopto Remote. Then you can turn the Primary Recorder on, which controls the Secondary as well. Once the recording has begun, you can use Panopto on the iPhone to join the same stream with your phone. Not sure why you would want to do that, but it's a great camera, I suppose if you had things setup right, you could have students use their phones to join the recording, or ambush them in class with hard questions on camera.

The key to all this is the following:

If you use the embedded player above, I'm not sure how you access the extra inputs.
If you pop out the full Panopto Player, at the bottom right below the screen you will see the user interface has changed, and a camera icon has appeared with a small triangle next to the Quality indicator. If you click that, you can access 6 more inputs besides the two you are viewing, plus you can toggle the large and small video contents. Notice here there are two mobile recordings that join the stream, the first is a screwup, so look at the second one, and note the begin at a certain time in the video.
Kinda crazy, huh?

Note that both of the Precision 5810's capture settings for primary and secondary were set to "Ultra" for the highest quality, but I have some sources backwards, and look at the difference between the Canon video, the Logitech, and the iPhone.

Also note the difference in price between the Magewell Panopto Recommended dongle and the Sam Burns special. We'll be ordering a few more of these to see how low we can go.

More testing and demonstrations of Panopto Remote on the way!
