Following the official naming conventions, if I put these movies and a poster image in the same directory (regardless of the directory name):
Movie Title (1980) - 1080p.mkv
Movie Title (1980) - 1080p {edition-Director's Cut}.mkv
Movie Title (1980) - 4K {edition-Director's Cut}.mkv
Movie Title (1980).jpg
…none of these movies will be matched with the image file “Movie Title (1980).jpg” as a default poster image and the image will not appear as a potential poster image choice in the user interface as expected.
What I would expect to happen is that supplied poster images without extra metadata in their file name would match as a default unless more specific files names are supplied. So for instance in this case:
Movie Title (1980) - 1080p {edition-Director's Cut}.mkv
Movie Title (1980) {edition-Director's Cut}.jpg
Movie Title (1980).jpg
…I would expect “Movie Title (1980) {edition-Director’s Cut}.jpg” to match “Movie Title (1980) - 1080p {edition-Director’s Cut}.mkv” across multiple resolutions, unless a poster image with a more specific file name was supplied.
This would make dealing with posters of movie files with multiple resolutions and editions in the same directory much easier, especially as default posters found online can change greatly from time to time if library metadata is refreshed periodically. This would allow me to use just one poster file for multiple variations rather than have a separate poster file for every single movie variation that I have.
Otherwise, please make it more clear in the documentation that poster image files must match the movie’s file name exactly in order to be recognized and provide examples.
