      Its interesting stuff. Adobe have offered it for years providing you use their flash media server. As already mentioned Silverlight can do it, but again you need some Microsoft tech on the server side. Apple offer it via http streaming which their more recent iphones, ipad, safari & quicktime can support, and the big advantage here is that you dont need anything special on the webserver. Obviously the drawback with the Apple method is that it only works on some client-side devices.

      All of these approaches require that you encode your video using the right tools, which will enable you to encode the video at more than one bitrate, to target users with varying bandwidth availability.

      Aside from the adaptive/smooth/dynamic bitrate stuff, the other advantage with this streaming is the ability to jump ahead in the video without waiting for all the earlier part of the video to download. There may be other ways to do this though, Im sure youtube does it and Im not sure what technology they use.

      As for the Red cameras, generally they create extremely large files compare to the cameras we are used to, its one of their strengths because it can deliver great quality but obviously causes some issues with having a beefy enough machine to do the editing etc. I cant imagine red format files being suitable for putting on the web at all, as depending on the compression settings chosen you could easily be looking at 1 second of video creating a file that is 1gb in size!

Imagine you've got a 1GB file - if you only download the first 100MB, say, you still get the whole length of the video, but in a lower resolution. That's as I understand it, anyway. So imagine a person with a slower connection >being able to view your video more or less immediately at a lower resolution, or wait for the resolution to build up.
