The iPhone already has hardware acceleration for h.264. It will have hardware encoding as well (it may already in the 3GS, although I haven't checked the specs).
I would imagine it will probably be in the area of 2500 - 5000 Kbps or so for 720P video. Standard DVD's top out at 9800 Kbps max rate (dual layer 8GB).
The quality you are talking about is fine for SD. Why are we even bothering to talk about HD video if you've compressed it in h.264 and your computation for space means one video file -- you've destroyed the source, the rendering and the final? You also need empty space to swap out files and memory. The 2 hour -online video is not even the quality of what you would see on a normal NTSC video stream.
There certainly is a lot of fudge room depending on codecs and if Apple has the ability to encode and edit in h.264 because of a chip on the iPhone -- I'd like that dang chip on my Final Cut Pro editing suite -- not because I'd every author in h.264, but just because I'd like to watch some TV while I'm editing.
Most Standard DVDs utilize hours of high quality compression. H.264 codec is a bit more efficient than MPEG of MPEG2, but its also more complex.
I think the STANDARD of Hi-resolution video editing, where people are trained on You-Tube quality, will work on the mass market... because they don't know any better. But it's not really HD quality editing on a 32G device for an 1 hour.
I expect this is more along the lines of a Novelty -- like those 12 Megapixel cameras with horrible optics and sensors. People will be making 2 and 5 minute masterpieces of their kids playing with a hose and chasing the cat and maybe superimpose a bouncing head of the dog.
I think there are a lot of video editors who might like it for quick "dailies" or whatnot. It's fine for playing back and tweaking compressed videos. But I'm not going to be able to use it as a real video camera on HD and then Edit my family video -- because I'm going to have at least 2 or 3 hours of the family on vacation. Plus, I think we'd all go slowly insane not having a 24" monitor and 50 or more tiny icons of the edit points.
The hype makes it sound like a serious HD experience and there is no way for a number of reasons, that it will provide that.
