In a live setting- like you have, you do not want to stop recording. You need the full audio.
You either shoot it with editing in mind. Ie: quick zoom and edit it out.
OR,
You shoot it live -this is what I recommend- you run the camera as if you are live on the air with everyone watching every move. You pan slowly, you zoom slowly, every move done well, done right, done smooth.
There is nothing wrong with zooming in on action, don’t fret it.
