Changes will be overwritten during rescan?

[lukass2000]

Hello,
I installed jellyfin on my Synology NAS, works great
When I manually adjust and change the metadata of movies in Jellyfin and then i click on "scan libraries" again, will then all manually adjusted content overwritten (for example, if I have changed cover images, or content descriptions,....)?

Or do manually adjusted things remain?

THANKS

Regular update scans should not change metadata already set. If you select "Replace all metadata" from the drop down, it would undo any manual changes you've made.
