Loud was the rejoicing of the multitudes when they found that yesterday’s QuickTime update added fullscreen playback functionality for even the non QuickTime Pro users. But plus in that update was a little bit of iPhone-related news: two new video export formats.
As with the iPod and the Apple TV before it, Apple has tried to manufacture converting video into an iPhone-compatible format as easy as possible. However, the real benefit for that feature is less for those looking to watch movies through the iPhone’s iPod functionality, and more about producing iPhone-compatible videos for the web. Hence the two formats: iPhone and iPhone (Cellular).
I gave them a try that daylight: From an 8.47MB 640×480 QuickTime movie, the former produced a 1.2MB 480×360 H.264/AAC encoded video which you can embed
Exporting in the 3GPP cellular format yielded a 176×132 H.264/AAC encoded video playing at 15fps, but one that weighed in at just 96k. It loaded pretty speedily by the EDGE connection, though the quality was noticeably inferior to the larger movie.
With a little reference movie trickery, you can set up your site to serve up 3GPP or M4V movies to iPhone surfers, depending on their connection speed. Check out Apple’s Developer Guidelines for how to do it.
