      I think the way to study it would be with on-site test subjects then start degrading the meeting, glass barrier, audio encoding, video screen, latency, etc. But the results would be frustratingly obvious: get better screens, speakers, and links than practicably exist today.

      FWIW I suspect better screens and speakers (and microphones!!) than what people typically use are very possible, just cost more money than people are typically willing to invest. Network links, I'm not as sure. Video encoders (=> high latency) are a big part of the problem.

      I suspect one issue is that there's a chicken and egg problem between hardware and software. I've been trying out a decent full frame video camera for VCs (I have the camera anyway). It's significantly better than a webcam in zoom, but barely or maybe not better in hangouts.

      This was true even in A/B tests that are from one room in a house to another room in the same house with gigabit fiber. If you look at local video, there's a *huge* difference in quality, but software assumes you have a very low quality webcam and compresses away the differences.

      I had not considered using my Sony A9 as a webcam. Amazing. Do you use external capture HW or does it support it directly via USB? FWIW we just tried two 90 minute VCs cross coast and facetime gave us better audio than I usually get with zoom.

      I'm using a Camlink Elgato 4k to convert from HDMI to USB (not in 4k, that's just the name of the device). I think you wouldn't want this for high quality video production, but it's cheaper than high-end video capture devices (it's $100) and very easy to use (just plug it in).

      We just decided on iPad Pro+airpods+facetime as the best VC setup (mostly empirical, but the theory is the single supplier can tune the whole stack). Now you've got me wondering if we should go full youtuber with studio mics and lighting. 🤔 Maybe in 2021.

      For personal use, I suspect you can get better video quality for cheaper with a used a5100 or a6000 for video (maybe 300?), arguably unfair comparison since you can get a used ipad also and maybe impractical for a company. On the audio side, I bet the issue for most people. . .

      . . . is noise from the environment, not sure if there's anything not very expensive that will fix that other than being near the mic and using low gain? You could try a very directional mic, but then people aren't going to be able to move, which seems like too much hassle for VC

      My primary concern is audio, both latency and quality. Our working theory is the directional mics in the airpods are hard to beat (I can be heard over Manhattan street noise). For latency, we have strong evidence that facetime has gone above and beyond (see earlier linked talk).

      That makes sense. I've been thinking of getting a decent lavalier mic (my company has a $500 budget per person for stuff like this, I can't think of anything better to do with the money), but since we (the company) use hangouts I'm not sure audio input quality will matter.

          I suppose I could try to do a comparison by (for example) sending some known high-quality audio into the input and seeing what kind of quality I get out, if there's no difference between audio quality from a high-quality source vs. my laptop mic then I shouldn't expect much.

          My main concern with a USB camera is I expect tons of pointless latency, just due to the driver stack. People with professional cameras use them to film videos to watch later, so don't care about latency at all. I expect it to suck more than an Apple-optimized iPad+Facetime.

          A lav mic sounds like a good investment, that's very much what I use airpods for. It would be fun to test them side-by-side and see if airpods take advantage of its two mics to do better noise reduction, and to see how the latency compares.
