Is it possible to build a website with multiple movielayers.
(layer 1 is toplayer in this case)
* On layer 1 we have text and actionbuttons
* On layer 2 we have a Presenter (filmed on a Chroma Key background)
* On layer 3 we have movies in a frame (but the presenter sometimes moves his hand in front of this movie)
* On layer 4 we have a general background
The movies have to be feeded from a database, so if we change those movies we don't have to cut the whole thing up.
This all has to be put on on the web, so it must be small, but with minimal quality loss.
Part of this bèta-website can be seen here: www.videoattitude.be, choose a language and wait. You won't be able to login, but here you can allready see the quality we have now...
You can't build interactive websites in After Effects, but you can build a site like you describe in Flash, using movies that you create in After Effects.
You may want to explore the ability to export After Effects compositions as XFL files for use in Flash Professional.
For additional information about working with After Effects and Flash, see this page.
No, really not. Hire a Flash/Flex programmer. Even XFL export will only give you ugly big files, not to speak of AE's own limited way of creating compound SWFs. And you'll need a database/ folder browser/XML parser, anyway, so it really boils down to good old-fashioned programming in Flash/Flex
