KeithAdv on "Help me use bigvideo.js in WordPress?"

I'm hoping someone can break this down so I can understand it!

I'm fairly good with css, just a beginner on javascript and php. Not so well educated on when/how to include/import stuff. But I'd love to use the jquery bigvideo plugin on a site, if I can get over the tech part!

Here is the BIGVIDEO.JS intro

And here is a tutorial by the creator

It's the simple stuff I trip over--where and how to include what--I just don't know how to WordPress-ify code like this! However, I'd love to get it up and running and all help would be appreciated! Thank you!
