Emby Low Quality Posters / Video Thumbnail Generation Failure

2026-06-22T15:42:59Z

Hi guys,
For the past several weeks I've been having issues with Emby fetching movie / TV posters and not generating video thumbnail chapter images for newly added tv shows.

I am having this issue on both of my Emby installations.

1. When I add a new movie, Emby is downloading the worst possible quality poster. Most of the time it's 200 x 300. A lot of times it skips downloading the backgrounds.

2. For TV shows, it is no longer generating images for each Episode OR Chapters in the episode. It uses the "Thumb" for these.

To make things even more confusing, the Movies seem to generate the chapter thumbnails properly. Only TV Shows seem to be using the "Thumb" .
I thought there used to be a setting in the Fetcher Settings to download highest rated images first, but I can't find it or it seems to be missing.

I'm attaching screen shots of newly added movies that Emby chose the lowest quality posters, a screen shot of a TV show to show you the thumb being used for chapters and episode images.

Attaching 2 logs, embylog and image log.

Oh, I have also completely refreshed my TV Show library replacing all metadata and images TWICE. I have triple checked my library settings, fetcher settings and compared them to my Movies library settings. I have also ran the scheduled task 3 times to generate video thumbnails for chapters.
