I am trying to map TVSHOW and TVSHOWSORT to iTunes with no success. I have mapped from MP3Tags to MP4 tags before, mapping INVOLVEDPEOPLE to DESCRIPTION, so I am confused as to why I am having such difficulties.
I cannot even get MP3Tag to read the values I put in through iTunes. Windows 10 File Explorer sees the information I enter in iTunes in the "Show" field, listing it under TV show Name. But no matter what I try MP# will not show it. What I enter in MP3Tag under TVSHOW, also gets reported to Windows 10 File Explorer, but under the title: TVSHOW.
I am assuming that the values I would have to map them to are tvsh and sosn respectively. I tried mapping: Tag=MP4; Source=TVSH; Target=TVSHOW, but anything I entered in a field defined as TVSHOW did not reflect in iTunes, even after I played the tune, which is supposed to refresh the information.
Well, that program does show the information inputted by iTunes, but not that which I place in MP3Tag. I still don't understand why this does not work as they are in the Field-mapping chart, which seems to indicate that they will work. I don't think it has to do with the type of file because MetaX read the video tag on the audio (m4a) file.
AFAI understood it: the data is stored in an extra data field with an xml structure. And this field is not read or updated by MP3tag.
Vice versa: itunes does not look at the mp4 fields but evaluates only the xml data.
This XML field in question is only for the "enhanced" details in movies and TV Shows like the actors, producers, directors, etc. The standard fields I indicated above are completely visible and editable in mp3tag as-is. No mapping required.
Even though I still "have" to use iTunes to manage the content for the many Apple devices in the house, I do almost all of my tag editing with mp3tag. This is for all music and videos. The only exception is for this "enhanced" movie info that I do currently use MetaX for.
