I'm wondering if anyone has thought about or come across any realistic methods for providing a full bleed background VIDEO to a site, without resulting in the site being dead slow.
Ideally I don't want to have to use Flash. And By full bleed I mean from edge to edge of the screen, like a desktop wallpaper.
Wait for HTML 5?
Since the rendering of the video (in whatever way it would work) is always done on the client, the statement "without resulting in the site being dead slow" is not really useful.
Could my current T60 Thinkpad (dualcore) render the video? I'd say yes. Could my girlfriend's Atom-based netbook do the same? I don't think so.
You've got to consider your minimum requirements for the client.
If you dont want flash then try using silverlight.
Animated GIFs did the job since the '90s. It's a bit blocky, but if it's blurred enough no one will notice :)
Take a look at my jquery videoBG plugin
