Dynamic incoming client bitrate

[geiserdrums]

Hi,

I was wondering whether it was better for a mixed audience (where, for instance, half of them have a low-speed internet connection, and the other half have high-speed internet connection) to show 720p or it was better to send 480p videos.

So, my question is the following: When sharing the screen from my main workstation (Or only sharing the application window, maybe it's different but I guess the tech stack when sharing in both cases are the same) is the video feed in the client being automatically converted to a smaller size, given their network capabilities? Or do they suffer in any sense? 

I was thinking about the low-end and low-network devices which connect to the Zoom meetings, and the idea of showing a video with a lower resolution was proposed (The video is sometimes shown through a given application, and sometimes the entire screen is shared). 

Thanks
