Minh and Julie....this was my idea for converting your power point presentations into videos. The positive side to this if you can do this in your webinar presentation is that you wont' have to talk about it. All you would need to do is make your own voice over to it and I'll re make the presentation to the length it needs to be for it to work. Then you can let it run and enjoy watching it. On the other had it's a very powefull and useful tool for your website.

This is version 1 using  a subtle effects.

 

This is version 2 using a flashier effects style.  

I also gave you a second version of music.
Both are good to use while voice-over is running.
