pre recorded webinar

Yes you can use the SIMULIVE Feature (which has pre-requisite of Zoom Events unlimited license) https://support.zoom.com/hc/en/article?id=zm_kb&sysparm_article=KB0058205

Zoom also has a replace recording feature (which also has licence pre-requisites and need to request Zoom to open it)

Thanks
can you please share a screen shot of simulive option?

Welcome to the Zoom Community, @talko.

You can’t do this with a standard Webinar license. You would need to acquire a Zoom Events or Sessions license to use the Simulive option. See this pricing page for details: https://zoom.us/pricing/events 

As an option, you can play a video from the Zoom Share Screen -> Advanced-> Video menu option. You’d have to join the webinar as Host and start this when you’re ready to begin the video.
