video as welcome introduction for a website

Hello Everyone,

First of all, I apologize if this is not the correct place to ask. I am new to this group, and also relatively new to Drupal. I made a site at my local computer and everything seems going well. I have one functionality, though, that I can't implement because I really don't know how to do it. I have been searching and reading posts here in drupal.org and also googled it for the past 2 days, but can't find any answer. Maybe I'm just typing the wrong search phrases.
