I started feeling vaguely funny about my new 5G 60 GB iPod purchase* upon hearing
the rumors that Apple was coming out with Yet Another iPod model. So soon, Apple? The rumors peg the new iPod as having a larger, widescreen format — and some even suggest HD video capability that would tie into a new, HD-enabled
AirPort Express and a Front Row sportin’ Intel Mac Mini.
Let’s put aside the problem of sticking decoding hardware capable of decoding HD video into an iPod form factor, which is simply 100% impossible right now. Let’s instead examine the particulars of this beautiful H.264 HD clip, and let’s even start the math with the “lower-res” 480p one**:
81.8 MB / 262 seconds long = .3 MB a second.
2 hour movie = 7,200 seconds.
.3 MB a second x 7,200 seconds = 2,160 MB, or about 2 GB.
So a 60 GB video iPod could hold up to 30 480p HD movies… which, to “buy” one online, you’d have to download 2 GB worth of video for apiece. Which would take upwards of: forever. Or, you could convert your DVDs to an iPod friendly semi-HD-resolution H.264 data format, which given how long Handbrake takes to convert one DVD to a MPEG-4 file of 320 pixels by 240 pixels to fit on the existing iPod, would also take upwards of: forever.
The main problem: neither “30 Movies in Your Pocket” nor “30 Movies on your Mac Mini” have the immediate marketing impact of “1,000 Songs in Your Pocket”.
Plus, I dunno, I think I’d kind of resent those large honking files hoggin’ up all my precious portable hard drive. Keeping 2-4 GB around of sometimes-watched, archived offline video on a DVD is fine, because it’s not clogging up my drive, and the existing low-res 320×240 iPod videos are around 400 MB at movie length, which is right on the edge of acceptable. But who really wants to manage files that are 2 GB a piece on their hard drive? A drag is what it is. If only you could keep video… archived offline… on some sort of removable media… maybe something circley and shiney***.
This isn’t to say that Apple isn’t working on cool stuff along these lines — a larger screen certainly would be nice — and surely the simple fact that I just bought one of the 5G models is enough incontrovertible evidence to indicate to everyone that the 5G model is very soon to be wildly obsolete, stuffed ignominiously in a closet with a ColecoVision Adam, daisywheel printer, and “Buck Rogers” cartridge.
But no, what I’m saying is: file size and hard drive capacity are going to be the big issues with any iPod or PVR that holds anything other than smallish, 22-48 minute, low-res TV shows. TiVo is skirting this issue in their upcoming generation 3 units by allowing for external storage; unfortunately for Apple, external storage for an iPod seems somewhat inelegant.

* which, don’t get me wrong, I totally love. I bought it for the capacity; for reasons I won’t get into here, I have enough legally acquired music to fill two of the things. It’s kind of a problem, actually.
** the math for the higher-resolution 720p and 1080p HD formats is even more impractical; 720p is ((219.7 MB/ 262 seconds) x 7,200 seconds) = 6,037 MB, or about 6 GB per movie, with 1080p averaging 7.5 GB per 2 hour movie, making your 60 GB drive hold a whopping 7-9 movies — and nothing else. Hope you like archiving to DL DVD! which completely negates the point, and might actually end up costing more for the archival media than the price of the video you’re archiving.
*** I dare to dream.
