Hosting a pre-recorded webinar

Hi,

I have set up an event for a webinar across 2 days. I had planned to deliver this webinar live, but due to scheduling conflicts, i am going to pre-record the webinar and share it with attendees.

I have set up a registration page and reminder emails for this, but how do I change the settings so that people will be watching a pre-recorded webinar at the time of the webinar?

Also, how do i go about recording this webinar? Would it be a case of starting a practice session and recording it?

Any help or support would be much appreciated.
