It's a aspect ratio thing "Open-matte is the general term for when a film is shown (partially or entirely) uncropped from what was originally filmed. This stems from when film stock was used and to achieve the desired final ratio of a film you typically had to physically cover part of the frame with a "matte", hence showing the entire frame without it was dubbed "open-matte"." quote taken from a Reddit comment that summarized it well.
I kinda forgot i posted here as a day or so later i figured out a way, like your first suggestion
But as plex would not recognize it by itself as i guess its not very common. I had to add the edition myself so i moved it to its own folder for manual plex import later when i can make sure plex gets has the edition and not is merging it with the a normal one. Tho if there is a way to add {edition-XYZ} to the folder name and not only the file name i believe plex could pick it up automatically but that needs some testing. If it works i can use your 2nd suggestion to add it as a function or to make it recognize it as an edtion. Or would it only add it to the file name as other editions do. As i belive plex would enjoy edtion movies in their own folders more than as versions in the same movie folder but both should work.
And thank you for quick reply even tho i read it way later, and its an amazing application
