lower resolution records in cloud , How can fix this? Alwais i had recorded in 720P

Hello. I have been recording to cloud zoom of my team meetings or my own meeting for a training video. 

Unfortunately, when I download the video, it shows up in a very low quality, often 640x350 resolution or lower and it nearly looks pixilated.  How can I fix this?

Always i had recorded in 720P but from 1 month to today is it impossible to record in 720P

I i record in my computerthe resolution is 720P but in cloud not.
