QuickTime updates add iPhone export
When found that the updated QuickTime added full screen playback functionality for even the non Quick Time Pro users there was a loud rejoicing of the multitudes. In that update there was also one iPhone related news which included two new video exports format iPhone and iPhone Cellular. 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. One day Dan Moren tried how to go through these formats, iPhone and iPhone Cellular.
From the 8.47MB 640×480 QuickTime movie the iPhone produced a 1.2MB 480×360 H.264/AAC encoded
video which one can embed in a webpage. When viewed it directly on the iPhone, Safari would not display it properly. Using the built in QuickTime player it played back smoothly and gorgeously on the iPhone just like Apple’s iPhone movie trailers. Exporting in the 3GPP cellular format, submitted a 176×132 H.264/ACC 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. One can set up his own site to serve up a 3GPP or an m4V movies to iPhone surfers depending on their connection speed with a little reference movie trickery. To know how to do it, one can just check out the Apple’s Developer Guidelines.
