Keep spatial resolution at expense of fps

[Incnis_Mrsi]

Hello.

I use Zoom to see lectures written on blackboard, often ∼3.5 m wide. Sometimes people at the auditorium are lazy to crop/zoom and pan the camera to specific areas. Given my poor internet, Zoom’s incoming video often degrades to the 320×180 resolution—that is, about 1 pixel per centimetre—which is completely unacceptable.

Can I force Zoom to keep receiving 640×360 even when it would result in less than 1 fps temporal resolution? Does it have respective hidden settings?

This is Zoom 5.13.5.431 (Ubuntu, amd64).

I don't think this is possible. If you don't have enough bandwidth for Zoom to deliver 360p successfully, how would forcing it to do so fix anything?

What means don't have enough bandwidth for Zoom to deliver 360p?

640×360 is about number of pixels and implies some amount of information. Information is measured in kilobytes etc. Whereas bandwidth is amount of information per time. It is measured in kbit/s etc.
