[4kLvr80]

hi everyone.

i downloaded some streaming videos as mp4s. the vast majority of them are recognized. Currently in my folder there are over 300. but i see some are not recognized by jellyfin. i even made those as mkv to test and they still are not recognized. here's the file info given by file explorer for some. also i should not i did not tinker with anything the way it was encoded. i just made them into mp4 using the preset.

What library type are the videos in? And can you provide example folder and file names?

[4kLvr80]

hi

the library type the videos are in is home videos and photos. the example folder name is ARROW VIDEO and a example file name is

39. Le Grande Bouffe - Newly restored _ back in cinemas. Official UK trailer

and another is

58. American Horror Project Vol 1 Trailer

these two files are examples that Jellyfin isn't recognizing and are both mp4s.

It’s probably a bug since the title includes the word "trailer." Try putting it in parentheses, like this: 9. Le Grande Bouffe - Newly restored _ back in cinemas. Official UK (trailer).

"Trailer" is a reserved word that should only be applied in movies and shows libraries.

So almost certainly a bug.

thanks guys it was the term trailer and how it was placed. putting it in parenthesis at the end of the filename solved the problem. Cheers!
