I want to create the banner in kellogs website!

Hi i need to create a banner very similar to the kellogs website in the way it works.

Basically i need a video to load up and start playing with ‘no sound’. The video will have a mask area that when you roll over it, the sound begins to play as normal in time with the video. Fir a better idea of what im after creating, visit kellogs website:
