    You can try mp4box, see http://sergey.marechek.com/blog/2012/01/07/149/ and see if it removes the metadata.

    Find mp4box.exe in the folders where you installed it and put in for example c:\temp .
    Put your mp4 in same folder.
    Open a command prompt, windows start and type cmd in the run box.

    Type
    Code:
    cd \temp
    mp4box -add video.mp4 newvideo.mp4 -new

  5. fantastic bladrik, thats seems to have stripped the tags, i wonder if i have a folder with 100 mp4s, would i have to do it to each one individually, and rename them to video.mp4 etc, then rename the converted file to the newly created file? or is there a way of batch processing it? its dlightly different to the scrub option listed in the link u posted?


    also as this mp4box seems to strip the tags, and the "copyright seems to be hidden, and alot of programs like foobar cant view the particular tag i want to change, however exiftools does, but doesnt support mp4's yet!

    do you know of any software that would actually let me edit the copyright and certain hidden metadatas to another value rather than strip it?

    kindest regards

    And no this is not an illegal IronMan copy. It was a short MP4 segment that I worked with the author because after editing certain MP4's, they would not play without using a hex editor to correct. Hence the Cover art character.
