I use a lot of video in my lectures & this sometimes raises concern for the host club because they’ve had poor experiences with video in previous Zoom presentations. I’ve never had this problem & I think it’s because I have a couple of critical settings selected in Zoom.

The important thing is to make sure the person sharing the screen with the audience has ticked the 2 boxes on the share screen - highlighted in the first image below.

Make sure your Zoom meeting is set up so only one person can share their screen at a time - you’ll not be able to tick the box “Optimize Screen Sharing For Video Clip” otherwise.

If you’re hosting you can set this option yourself in your Zoom control panel, otherwise if you are the one doing the sharing, ask your host to make you the host (or co-host) & do it from your “Share Screen” - see second image below.

I’ve tried other remote delivery services (Go To Meeting, Teams, Skype) & I’ve found none of them to be as proficient at handling video (this includes AV slideshows set to music) as Zoom… but I’ve always had these settings selected. Hopefully this will help you if you’ve been having problems.
