    Video formats supported by iPhone: H.264 up to 1.5 Mbps and MPEG-4 up to 2.5 Mbps
    Posted 27 June 2007 @ 11am in Guides/How-Tos


    The iPhone supports the exact same set of video formats as the current 30GB and 80GB iPods, meaning that video exported for use on the iPods should be immediately usable on the iPhone.

    The supported formats are:

    H.264 video, up to 1.5 Mbps, 640 by 480 pixels, 30 frames per second, Low-Complexity version of the H.264 Baseline Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats;

    H.264 video, up to 768 Kbps, 320 by 240 pixels, 30 frames per second, Baseline Profile up to Level 1.3 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats;

    MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats

    H264, in my opinion, gives the best bang for the buck when it comes to video quality vs file size. (talking about my own encoding) It's not too harsh on processors for playback, either.

    Seems to be gradually displacing MPEG on CE these days.

    I think HandBrake is a freebie that supports H264. It was really simple, and ended up being one of my preferred apps because I have better things than figuring out a million settings and testing them over and over.

    ffmpegx works pretty good too - I purchased the "full version" and wasn't too impressed with what I got - the basic version works fine. (full version supposedly allows you to convert DVD to whatever format you choose - but it will not do a full extraction which stinks)

    I think Imovie HD will output H264, but I'm not sure how easy it would be to load a video into it, and then export it (under advanced tab) to H264.
