Video resolution on the the recorded meetings

Yes, this is possible, but there are a number of stipulations.

First and foremost, all users being recorded will need to have a camera that supports 1280x720 resolution (common in 2024, but not a given), a computer/device with adequate specs that has appropriate resources to devote to Zoom, and sufficient internet bandwidth.

Once these requirements are met, you will need to enable HD video on your account.

Instructions, requirements, and limitations are listed here:

Note that Zoom may also try to conserve bandwidth and downscale both transmitted video and cloud recording resolution if at least one far-end participant is not viewing 'active speaker' in full screen (and full resolution) - this is not published, but has been found to be true after a series of tests.
