Working with MPEG-4 clips on mobile phones

Douglas Dixon, author of "Adobe Encore DVD: In The Studio" and "Desktop DVD Authoring", writes about the pain of working with MPEG-4 clips. More and more people are buying cellphones with photo and video capabilities and therefore every day the amount of media recorded with these devices increases. I hear it all the time: "This is unusable, I can't figure out what to do with the clips anyway." An article like this can certainly help.

Douglas Dixon uses the QuickTime Player to view and deconstruct clips created by several camera phones. He examines the details of the MPEG-4 format for mobile phones - called 3GPP - and works around some of the idiosyncrasies of how different devices create slightly different formats. This article is an excellent stepping stone, a good coverage of a topic I haven't seen discussed in this detail before. It may seem like a trivial topic to some people but I constantly read on newsgroups posts from people that ask how to convert from one type of clip to another and this is the answer, or rather a step-by-step guide.

As a curiosity, Dixon shot video clips with three camera phones: the LG VX7000, Motorola V710, and Samsung SCH-a890.
