    I've been adding all of my movie files into iTunes and have found one that for some reason can't be added. It plays in QT and as far as I can tell all of the specs are correct. Can anyone see something wrong with this file that I am missing?
    This came from MediaInfo.

    Code:

    I am guessing that the reason is that you have just barely exceeded the specs on the max frame rate. I believe it is 30 fps while your video is 30.303 fps.

    To be honest, I have not seen this isom codec ID before.
    E.g. one of the movies I have converted with HandBrake, carries this informaton:
    Code:
    General
    Format                           : MPEG-4
    Format profile                   : Base Media / Version 2
    [COLOR="red"]Codec ID                         : mp42
    [/COLOR]File size                        : 1.72 GiB
    Duration                         : 1h 45mn
    Overall bit rate                 : 2 331 Kbps
    Writing application              : HandBrake 0.9.9 2013051800

    I'm pretty sure you're right. I checked a handful of my other files and nothing got much higher than a little above 24 fps. I wonder why this file is different.

    I use MP4Tools when I just want to change the container, I guess isom is related to that.

    Thanks to both of you for your help. I'll keep tinkering until I find a solution.

    This is what jumped out to me as well.

    EDIT: Woops, actually I meant the bitrate. Have you played other videos that have 30Mb/s? bitrate? That's really high for h264. I'm actually really surprised it only comes out to 15GB. I do half that for my 1080p movies and I get about 10-12GB per movie.

    After I read your post I started checking other files for their bit rate and found that the TV version of Repo Man also had a max rate of 37 Mbps with the max frame rate at 30.303 fps. It was also missing from the library. I need to do a more thorough check next time. Thanks for the info.

    As with everything Apple, it's "THEIR WAY... OR NO WAY".

    Thanks to everyone with their suggestions. I re-encoded the two files instead of using pass thru and this brought them back down to the required standards. I'm not sure why things expanded like they did, the bit rate for Safety Last's mkv file was around 27 Mbps, but the Repo Man mkv was only 15 Mbps. I don't know enough about the process to understand why it would go from 15 to over 30, but changing it from pass thru to 2-pass in MP4Tools worked.
