Great website techniques

Hi,

I have been checking through some the webs latest and “greatest” flash websites and was amazed with what I found! There are two websites I was particularly fascinated by:

The first is at this website:

http://www.fantasy-interactive.com/#start

It uses flash video in a very sharp and crisp way. I have followed various tutorials on how to apply video to the web via flash but the quality of my Flv movies do not come out any where near as well as theirs!! Does anyone know of some worthwhile tutorials on high end video for the web via flash?

Ok, the second is at this website:

http://www.adobe.com/special/acrobat/tour/worktogetherbetter.html

This site also uses high quality video but uses a neat little trick were there are several pictures of various people who look at your mouse when ever you move it around! Does anyone know how this is done?

Thanks for your time, if anyone can offer help such as tutorials etc it would be much appreciated.
