    Can anyone recommend a tool that will scan a video file and report whether the file itself meets Apple's requirements for playback on the ATV? As I convert my library from MKV to MP4, I am finding that certain movies don't stream so well to the ATV. This typically happens with the larger files (>2GB). The symptoms I am experiencing are quite varied but they all make viewing movies a bit of a hassle.

    FWIW, all of my movies were converted using MP4Tools and in most cases, the video files were simply converted by MP4Tools. Only a handful of movies needed to be re-encoded.

    Thanks in advance for the suggestions.

    I have this same issue occasionally when I try to play a video in iTunes that I converted. My solution is to buy a roku and use plex lol

    Since you indicate it is a file size issue, you might try using Subler to "Optimize" the file.

    I have the same problems sometimes , is not about the file size cause I have movies from 1gb to 12gb
    Maybe something went wrong with your encode , try redoing it

    When that happens to me I just download another file , yes you heard right

    Use iFlicks with the "itunes compatible" preset

    also optimising is good, but won't solve your issue

    There's a free app called MediaInfo that will display all the down-and-dirty specifications of your media files. You can compare that information against the AppleTV audio/video specs to determine whether you need to simply remux from mkv to mp4, or re-encode to make it play nice with the :apple:TV.

    Below is a screen grab of the output from one of my movies:

    I use MakeMKV to rip my Blu-ray's to MKV, then I convert to MP4 with Handbrake, using the "Apple TV3" setting, and I haven't had any issues. The one thing I do before Handbrake is to play the MKV file in VLC just to make sure it plays properly, and sometimes I forget to remove an audio language and it will play in French or Spanish.
