Ugh. Multiple compression streams? Why? 720p would be too much IMHO.

  >Multiple compression streams? Why? Zoom automatically switches between quality levels based on your connection speed, who's talking and the size of the viewport. 720p would look fairly rough when fullscreened on most non-mobile displays, but it's orders of magnitude more than necessary when viewed as a thumbnail on a mobile device. Making multi-user video work in a mostly seamless fashion is a surprisingly hard problem. Using a single stream would substantially degrade the experience, which may be a worthwhile tradeoff for high-security environments but certainly wouldn't be a worthwhile tradeoff for most users.

  720p is the standard laptop camera these days. You notice if anyone streams less. Next, desktop sharing is going to be at least 1080p. Then you need to have lower resolutions for anyone who can't handle that much on their connection. Same for desktop share.

  It's not just about the resolution, but also the bitrate and fps. Perceived video quality is a big deal to companies like Zoom. I don't blame them for not using E2E, it's a tough technical issue, but I do blame them for lying about it.

  > 720p would be too much IMHO. I may be spoiled with a good real 50/10 Mbit connection but for me in 2020 720p is the bare minimum. Expecially when screen sharing.
