Update library always rescan same group of movies

When I update my movies section, some of the movies that are already in the library for months are again scanned, this happens for every update, without any changes on them. This only happen to 5% of the movies.

The logs for the correct movies are like that:

DEBUG - Looking for path match for [/MOVIES/Godfather III (1990).mkv]
DEBUG - Path matched, we’re reusing media item 14204

And the logs for the affected movies are:

DEBUG - Looking for path match for [/MOVIES/Godfather (1972).mkv]
DEBUG - Path matched, we’re reusing media item 14202
DEBUG - Noting item as needing media analysis, scanning=1, streams=0, missing channels=0, streamability=0, size=0, time=0.
DEBUG - Turbo analysis on modified item 14202 [/MOVIES/Godfather (1972).mkv]

I have checked permissions and everything is identical to the movies that are not affected, same folder, same permissions…

Any idea of what happens to these files??

Thanks

Plex keeps track of changes by the timestamp on the folder. In your case, you have your files in the “MOVIES” folder. So any change will result in PMS rescanning all your files to then look for changes to the file. If you place your files into dedicated folders per movie, then only those movies where their individual folder has changed will get rescanned.

DEBUG - Noting item as needing media analysis, scanning=1, streams=0, missing channels=0, streamability=0, size=0, time=0.

That means that PMS has not performed it’s analysis process on that file. If it keeps doing this then there could be something wrong with the file so that the analysis can’t be done, but PMS keeps trying.

Thanks for your help @“MovieFan.Plex” . In this case it should be the second option, something is wrong with these particular files.
this happens always for 5 files in a folder of 100 movies. No changes in this folder and if update always same 5 movies are rescanned with this message. I guess the only option would be rebuild or repair those files.

If you can create a 30 second sample of 1 or 2 of these and make sure they exhibit the same problem, then share those samples with me. Maybe we can fix it on our end too.
