    Is there anyone out there who can think of a media item (audio/video) with at least 512 bytes of metadata?
    Preferably, something available on a smartphone?

    Many thanks

    First question, why? Steganography?

    I'm pretty sure you can just tack-on data to the beginning of the file, before the file indicator, and when you run the file, it'll just be ignored (though it probably depends on the software used. It might cause it to refuse to run as well).

    EDIT: I just did a quick test. The file refused to play. This might not be a general outcome, but still.
    I know that certain files can have variable meta-data sizes. BMPs, for example, has a part of the meta-data stating the size of the rest whole of the meta-data, you could edit this and have more room to work with at the end of the original metadata (if that makes any sense :p). You could also edit the "author, album, etc;" part of a music file.
