What do you mean man ^_^ Where do you need that video ?
Is it a Youtube video you want to embed ?
Or do you have the video inside your PC ?
If it’s a Youtube video, you can just paste the link inside the WordPress visual editor.
Or use this shortcode, it should work.
[youtube=http://www.youtube.com/watch?v=JaNH56Vpg-A&w=640&h=385]
Change the URL to your video, and change the W for width and H for Height as you wish.

If you have a file on your PC… well you can add it as media I think but with a 64 MB limit, which is small.
I suggest you first create an account with Youtube or DailyMotion, upload your video there, make it private if you need to, and then embed it on your blog.
Good luck
