Having trouble showing video clips via Zoom at Club meetings?  The video looks good to you, but your members see very jerky video that is drastically out of sync with the audio?  
Low upload bandwidth (speed) may be the culprit.  Go to www.speedtest.net and press go.  If your upload speed is much less than 10 Megabits/second contact your internet provider about upgrading your internet service.

Alternatively, ask your members to run speedtest and report if they have 10 Mb/s upload or more.  Then designate a “projectionist” – send the video file to them in advance of the meeting.  They can have the video queued up and ready to go on demand (and often with less confusion).

Also, be sure to check the "enhance video" box at the bottom left of the share screen.
