Provide HTML5/CSS3/JAVA code samples/advice - video in browser mostly

To assist us with an ongoing project by providing a one page working sample of HTML5/CSS3/JAVA (Fully remarked for implementing it). We need the html(5) page to show an mp4 video for 5mins and static html page for 2mins and then another mp4 video for 7mins (plus any java that might be used). This will work through Firefox only (latest version) , no flash player will be used to show the video. A transition effect might be needed to smoothly link the three (switching layers at the alloted time will be perfect). An agreed bonus will be paid for changes above what is listed here. ## Deliverables We need one (fully remarked) html(5) page to show an mp4 video for 5mins and static html page for 2mins and then another mp4 video for 7mins (plus any java that might be used).
