Consistency of video content

Hello, the idea is to encourage 500 staff to create an instructional video and post it to a SPO site, to share knowledge. I need advise on how to create consistency with the video content. Can you create a stream template? I can provide staff with a guide on how best to create an instructional video, but am looking for something more concrete. For example is it possible to create a web part template?

As i would like to ensure all videos follow a pattern i.e. must be under 5 min, introduce concept, middle, examples, end, recap  

I would greatly appreciate links to any documents, examples

TIA
