Details list mode

In details list mode right mouse button click on the column headers to pop-up the options menu.
Hide default or add custom columns as needed.


When setting the iTunMOVI XML tag, cast is set in the 'cast' XML branch. Involved peoples are set in the specified "Function" branch.
iTunes sets for example directors in the "directors" branch, so you have to specify the director as a "Function" 'directors' even when there is only 1 director.
Please try saving an example MP4 file with iTunes to find out other crew "Function" names.

Using templates

Tag templates can be used to apply a collection of tags that are needed multiple times to the MP4 files. For example if regularly publishing MP4 video files, it's possible to create a tag tamplate with an URL, a copyright and an e-mail address, etc. and apply these tags every time when publishing a new video (or multiple videos).
To create a new tag template use the menu item "Template/Create New Template..." or open an existing MP4 file in the detailed tag editor and use the "Export..." button at the top-left corner of the window and export the tags to a new file. To edit this file use the menu item "Template/Edit An Existing Template...". Note that these tamplate files are actually MP4 files with just the tags (no audio/video), so they can be managed just like ordinary MP4 files.
When a template is ready add the MP4 files that are to be tagged to the stream list, use the menu item "Stream List/Select All" then the menu item "Apply Template To All Selected Files...". A dialog will pop-up to specify the template file and the merge mode to be used to batch tag these files.

Replacing ffmpeg

In case there are any issues with video thumbnails or audio extracting functionality, or just wish to use the latest version, optionally the provided ffmpeg build can be replaced with for example the latest version.
Simply download the latest ffmpeg build and copy all the files to the installed folder's 'Tools' folder (usually 'C:\Program Files\MP4 Video & Audio Tag Editor\Tools'). It is recommended to create a backup of the existing folder, eg. just rename it, before copying the new files, just in case.
Note that it is not guarantied that the new version will work for sure but might have eg. support for new codecs for example.
