HTML Play Video

I need some advice on how to play video on a website. What I would like is to have a clip link on the page, and upon being clicked, a video player expands to the middle of the screen and plays the video (and has the standard video player controls). It also has "X" to close the video. I would suppose there is a widget or tool for this but I can't seem to find it.

Also what video resolution and format would be best (most compatible with browsers)? The video would just be a local file on the server.

Try look here:
