As I am running classes outside you will find that the audio and video quality may deteriorate.
See the attached image for advice on how to get the best from Zoom.
In future, on outside broadcasts I shall switch off video.
I suggest you do too.
If we are on an inside broadcast and you are getting video quality problems, I suggest you turn off HD video.
From now on I shall have HD video turned off as I very rarely ever record and keep and use video.
