    ok so i have a lot of hd movies on my computer in various formats from mkv to mp4 and i want to convert them (keeping them in 720P) so they can go on my iphone 4, i have the programs visual hub and i have imovie hd but thats it as of now, can anyone give me a crash course in how to take a movie thats hd and get it to fit on the iphone? i have a version of minority report that is in mp4 and 720p however it will now allow me to watch it on the iphone after i transfered it it said the video was not supported, any help would be great, if there are any free programs that can make this easier please let me know or if there are settings i can adjust in visual hub to make the videos work, i just dont want to have to downgrade the movies into standard def

    The iPhone 4 will allow an mp4 up to 640x480. That's why it comes up as not supported.

    Here's the excerpt from Apples site on the Video Formats and sizes:
    Video formats supported: H.264 video up to 720p, 30 frames per second, Main Profile level 3.1 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 per channel, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; Motion JPEG (M-JPEG) up to 35 Mbps, 1280 by 720 pixels, 30 frames per second, audio in ulaw, PCM stereo audio in .avi file format
    Subsequently, I use Handbrake for most of my video conversions. Its free.

    I'm not sure if this has anything to do with that, but when I looked at the 720p iphone 4 preset - the video framerate is set to "same as input". That should be 29.97fps.

    Here's a discussion thread over at Handbrake Forums on conversion -> Link

    I downloaded the presets but could only import the SD preset and not the iFrame or 720p preset. Can anyone just give me the presets so I can make them my self?

    Wow, a lot of misinformation in this thread. The iphone 4 will support any resolution based on multiples of 16 up to 1280x720. What matters for being supported is that the level isn't above main 3.1 for h264 stuff. Movie framerate should be 23.976 fps. Doing 720p is pointless unless you only use the phone to play HD stuff to a TV, but still pointless because you obviously have a computer and TV that can do it. I use 960x640 with black bars, main 3.1, and whatever framerate is. It even works up to 59.94 fps. I have a 72 fps video I have not tried playing yet, as I don't own an iphone 4 yet, I just have people test the videos I encode. I also don't use any 1-step programs, I prefer to do things the hard way, but I have better quality files.

    it's not necessarily pointless. I put hd movies/tv shows on my phone so that I can play them on a tv at friends houses.
