Series Sorting

[Snofru]

Hello!

I have a strange problem concerning the Series-Order under "newest series". 

I have the following (simplified) situation:

library "series" has 4 series:
- series A (2011-2015)
- series B (2016-2021)
- series C (2021-today)
- series D (2023)

Under Server-Settings -> Librarys -> Display -> "Date added behaviour" i have chosen "use file creation date".

All timestamps of the Media-Files of Series A-D are correct, except one Episode in A and one Episode in B which have a tiimestamp of 2058 . As consequence, the order of "last series" in the Main-Screen, the Series-Order is "A, B, D, C". After i found the problem with the two timestamps in the far future, i changed it to the corresponding year of the other files of the seasons and updated the librarys in jellyfin. If i check the metadata, no indication of 2058 is found there. However, the Order of the series is still A, B, D, C and not D, C, B, A.

What do i have to do, to change it in the home-screen / under series / latest episodes?

best regards!

Let's start with what your end goal is...because this is a very abstract question. There might be a better way to get there. Are you hoping to sort/display by latest aired episode first? Are these actual series? Can you get the metadata from a provider and use that information? Or are you utilizing an outside metadata/organizer program that can alter timestamps/file creation dates?

To answer the abstracted version of your question, I would look deeply at the existing metadata of the file inside of Jellyfin and see what field contains the incorrect timestamp and try to find where that information exists within the file on the host OS (ffprobe, mediainfo, ls -hl, right click > properties, etc...).

The name of the file, in some cases, may even cause this issue. I have a process that pulls down web videos and includes automatic resolution information in the file names -- despite the timestamp, date created, date uploaded, and more info being included in the metadata, Jellyfin still sees these videos as being released in 1920 if they're 1080p (i.e., "1920 x 1080" exists in the title). I'm not sure how to correct that behavior and I can't use a metadata provider to pull information for these videos, so I deal with it.

Yes.

I am using TheMovieDB/The Open Movie Database. The Data, Description, Airing Date, Actors are up-to-date and correct.
I have not modified the MetaData in any way, and did not use the "Metadata-Manager" from Jellyfin.

But i was able to found the problem: I have only changed the timestamp of the corresponding media files in the filesystem to a reasonable value and updated the meta-data of the Library in Jellyfin with "Scan for new and updated Files". If i check the MetaData with the Metadata-Manager from Jellyfin (as you suggested), there was still the wrong timestamp -> "added in 29.06.2057" at the episode with the wrong date at the file. Even a Rescan with "Replace Meta-Data" did not make the change.

Of course, the "added Date" cannot be read out from metadata (i did not consider that), so i changed the data by hand within the Metadata-Manager and it worked.

Thanks and BR!
