Hello, Rogerz! Welcome to Wikivoyage.
To help get you started contributing, we've created a tips for new contributors page, full of helpful links about policies and guidelines and style, as well as some important information on copyleft and basic stuff like how to edit a page. If you need help, check out Help, or post a message in the travellers' pub. If you are familiar with Wikipedia, take a look over some of the differences here.
I'm sorry, but to date, videos haven't been permitted on this site. See Wikivoyage:Image policy#Other media. If you'd like to suggest a change to this policy, you are welcome to do so, but I'd recommend for you to read the existing thread at Wikivoyage talk:Image policy#Proposal to allow video files first and try addressing the points already made there.
All the best,
