Can videos be pre-loaded to the webinar

Once a month we host a webinar for 300+ employees all around the world.

We always show videos, but as they're being "streamed" from locations with less than perfect network performance, they are jumpy, audio is not synchronized, etc. So the impact of the videos is tremendously negative.

Does Zoom Webinar offer a solution?

In other webinar tools I've used, they had the ability to load the video to the scheduled webinar and thus run it from the webinar platform.

Looking forward to your respons(es).

Cheers, James
