    What is the best quality video that I can play on the iPhone?

    Here is what Apple lists as supported:
    VCodec / Resolution / FPS / Max Bit Rate
    H.264 / 640x480 / 30 / 1.5 Mbps
    H.264 / 320x240 / 30 / 768 kbps
    MPEG-4 / 640x480 / 30 / 2.5 Mbps

    Apple also lists the audio guidelines:
    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;
    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;
    Simple Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats


    Here is my success/failure:
    VCodec / Resolution / FPS / Bit Rate // Audio Codec / Sample / STATUS
    H.264 / 320x180 / 29.97 / 128 kbps // AAC (Stereo) / 44.100kHz / PASS
    H.264 / 320x176 / 24 / 127 kbps // AAC (Stereo) / 44.100kHz / PASS
    H.264 / 480x202 / 29.97 / 128 kbps // AAC (Stereo) / 44.100kHz / PASS
    H.264 / 480x320 / 29.97 / 128 kbps // AAC (Stereo) / 44.100kHz / PASS
    MPEG-4 / 512x224 / 25 / 79 kbps // AAC (Stereo) / 48.000kHz / PASS

    H.264 / 720x480 / 29.97 / 127 kbps // AAC (Stereo) / 48.000kHz / FAIL
    H.264 / 720x304 / 23.98 / 127 kbps // AAC (Stereo) / 48.000kHz / FAIL

    I have some DVDs that I would like to encode that will give me the best possible quality. I would love HD, but it looks like the iPhone does not scale down 720p. I will, at some point be getting an Apple TV, so I want it to look good on that too. What other successes/failures have people experienced with the encodings?

    P.S. If anyone knows how to make tables in posts, feel free to PM me ;).

    Nothing? Surely other people want to get the best quality they can watch on the iPhone...

    Maybe I need to ask an Apple Genius about this?

    Hey man. I dunno about all that (but I do know about all those settings since I used to play around with PSPVideo9 on my PSP), but you should just download VisualHub (assuming you have a Mac). Flip to its "iPhone" setting and then scroll it over to "Wifi" quality or beyond. As long as you have H.264 encoding selected, it'll look beautiful and I guarennte you'll be impressed. Later
