Problem sharing screen with video

Hi,

We organise online seminars where videos are being shared on screen and reviewed and commented by a professional . We have a ZoomWorkplace Pro Monthly plan and with a few members this works but as soon as the group is a little bit bigger the videos start lagging.

I am the host and I have excellent internet connection, the videos are stored locally (so not internet based) and I see the videos perfectly on my screen. However for many participants they are lagging behind which destroys the whole purpose of the seminar. One participant changed from a PC to an iPad and it worked better.

Has anyone experienced this before? How can we solve it? Our next seminar is in a few weeks and I am wondering if we need to look for another provider.

Thank you!

Welcome to the Zoom Community! We're glad to have you here.

Video lag for participants in larger Zoom seminars is likely caused by device limitations or bandwidth constraints on the participants’ side, not the host’s internet or local video storage.
You may want to advise participants to use newer or Zoom-optimized devices, such as tablets (e.g., iPads), which can sometimes offer smoother performance than certain PCs. Encourage them to connect via a stable, high-speed internet connection for best results. If video lag continues, consider reducing the video resolution before sharing to improve playback quality for all attendees.
