Vox Pop: Want HD video from iTunes and Apple TV?
Merlin Mann | Mar 25 2007
Since the new TV can handle video up to HD's 720p resolution, there's been a lot of speculation about whether the iTunes store will eventually start selling HD content, such as TV shows and movies. You can bet that the desire for that quality of presentation is theoretically out there (at least it is for this HD TV owner). The problem, as many folks have discussed at length, is that the file size for HD movies, in particular, may be prohibitively large for the garden-variety home broadband user.
As Greg Keene notes, "With simple math, we can extrapolate that a 2-hour movie would be about 3.9 GB." That's not only a substantially lengthy download for, say, a residential DSL subscriber, it also represents the investment of over 10% of the available space on the Apple TV's drive (as well as, it should be noted, an equivalent chunk of space back on your Mac or PC's disk).
In his very good "Apple TV: iTunes Store Movie Quality vs DVD, HD, Cable," Daniel Eran writes:
This is one reason I think the Apple TV may be giving a kind of temporary competitive advantage to producers of shorter-length HD content, such as -- well -- let's say video podcasters. It's a big reason behind our decision to start shooting and releasing The Merlin Show in 720p over the next month or so. The current hi-res version of the show -- which actually looks pretty good on my Apple TV -- is presented at widescreen 854x480, which makes our most recent, 14-minute episode weigh in at 88 MB (about 6 MB/minute).
Here's a comparison of the three screen resolutions (720p, hi-res/854x480, and iPod/320x176) for reference (This is just for relative size comparison; you can mentally change the image's "mm" to "px.")
Seems to me that the typical expectation for podcasts is that, while they will be released on a relatively regular basis, they will also get downloaded automatically in the background and then get synched to a device like a Video iPod or TV for viewing at the user's convenience.
But, movies, and to a lesser extent, single episodes of TV shows, strike me as more of an impulse item -- something you want to download and watch more or less now. Knowing there's two hours and multiple gigs of disk space between you and Norbit might be a disincentive to downloading, right? But, then again, people don't seem to mind the wait of their Netflix queue, right? I dunno. You tell me.
Given the constraints of time and disk space, would you purchase (and wait for the download of) HD content for your TV? What do you think is an acceptable resolution for content on your HD TV? Anybody hacked on their unit yet? Whither TV, iTunes, and HD?
