I use MP3TAG to manage my Video MP4 because its the easiest. The problem I have had for a while is that information is in the %comment% field and I need to use Tag-Tag copy it to %podcastdesc% field it previews as blank.

Now if I manually enter information in %podcastdesc% I can see information.

the %podcastdesc%is the field Itunes and AppleTV use to show a description of the video or movie aka Plot

the %tvseason% and %tvshowepisode% are working fine

I can't reproduce this behaviour.  
If I try to copy the content of COMMENT into the tag PODCASTDESC I can see the preview as expected:

How exactly ([screenshot](https://community.mp3tag.de/t/hints-for-asking-support-requests/56190#use-screenshots-to-exemplify-the-issue-2)?) do you try it to get the preview as blank?

its actually the other way around. The %comment% has the data I want to move to %podcastdesc%

The Field PODCASTDESC in this Convert Tag-\>Tag case is the TARGET field.  
The Format String combines existing SOURCE fields (or parts of the content of such source fields).
