This way loading a project does not require having external source files present. Yes this makes a big bloated file, but this is only for the "in production" stage of the editing. Once done, you'd have the editor implement a command to produce the final video, similar to photoshop's "flatten image" command that elimintates layers. In this step the file would actually be rendered to a single audio/video stream with the selected codec(s) and any dynamic effects like fades or transistions actually rendered into frames. This way if you wanted to go back and make changes later, all you need is the original file with all the data, you don't have to hun

Mmm, basically that's what Matroska files are like. Except that the data 
have to be interleaved in sync...
