The only good solution to this one that'll work is to get Zoom to let you do it.
As far as I'm aware, this
is still their guiding regulation:
Note: Due to recent events with COVID-19, meetings in 720p-quality video are only available to Pro account users or higher, and only for meetings with a maximum of 2 participants; 1080p quality is for special-use cases currently. For more information, please see our requirements for Group HD
Nothing to do with vMix, NDI, or anything else but Zoom, and nothing you do short of getting approval from Zoom will change it.
Zoom, Teams, etc. are designed around standard meeting webcam use. The average meeting participant doesn't care if they see their boss sitting at their desk in HD or SD or with a high frame rate or a low one, since they're not really moving.
vMix allowing you to expand beyond that is great, but you're going to see issues, like you're seeing, from trying to shoehorn in these elements that go beyond what the software is accounting for.
Under normal circumstances--the circumstances they're anticipating and designing around--the bandwidth necessary to make text look crisp & transitions smooth is nothing more than an additional expense on their server.
Zoom is even very open, as I pointed out, about the fact that they don't allow it and why.
Your problem isn't vMix, your problem isn't NDI, your problem is that you're trying to use pro-grade presentation and broadcast tools on services designed and maintained to serve users with standard webcams, in standard meeting environments.
Go back and watch late night talk shows from earlier in the pandemic where they're conducting their interviews with that pricey Cisco meeting equipment. Even those look like garbage because even the expensive, high grade side of the virtual meeting space is prioritizing things that broadcast isn't.
What you want is either a peer to peer solution, where they don't care how much bandwidth you use (because it's your problem to account for), or a webinar solution, where they're designing for presentations, not meetings. Any sensible virtual meeting software (even, again, the high end options) will make sacrifices and include limitations that run against what you hope to do.
I join you in wishing that weren't the case, but it's how it is.
