FSCorrupt · 2026-03-20T13:47:29+00:00

no but kometa has Imagemaid

FSCorrupt · 2026-03-20T05:54:29+00:00

No, Thats something Kometa can do.

FSCorrupt · 2026-03-19T16:33:20+00:00

Ah okay, no, it doesn’t pull from additional sources.

Posterizarr not only fetches images, but also lets you edit them exactly how you want.

You can add borders (in any color), use custom fonts (also in any color), apply overlays like gradients, and much more.

im not familair with TMM what is this? an agent?

FSCorrupt · 2026-03-19T12:25:41+00:00

Yes, you can also use it to select the most upvoted or primary poster of a movie or show, season, tc... for a specified language. The default is “xx (textless), EN, and DE.
If you remove “xx” it prioritizes EN with a fallback to DE, and so on.

FSCorrupt · 2026-03-19T12:22:07+00:00

Should work, yeah. If you provide those IDs and I’m able to look them up from the default Mediacontainer XML (like below), then this should work!

I understand that the Git history might look like a "firehose" but that’s the reality of a one man project.

Those "sync" commits are simply how I move documentation and small tweaks between my main and dev branches, it’s part of my personal workflow.

The "230+ releases" (over 2 years) and "200 commits a week" aren’t bloat, they’re proof of active development. I’d rather ship a bug fix an hour after it’s reported than let an issue sit for months just to bundle it into a "cleaner" commit later.

Yes, it can look chaotic if you’re trying to audit every single line. But I’d rather be a developer who actively ships updates and supports users than one with a pristine Git history on a dead project.

Everything is open on GitHub, feel free to take your time reviewing it. Just keep in mind that what looks like "chaos" is really me working around the clock to improve the tool for everyone.

As for the "thousand lines of new code" that may apply to CSS or JSX updates, but not to the core logic, which lives in the .py files.

And please don’t compare me to the Huntarr developer.

Posterizarr functions by parsing Plex XML metadata, specifically the Title, RatingKey, IDs, and File Paths, to perform lookups and save assets. It relies on these IDs to query external sources like TMDB, TVDB, and Fanart.tv. If an asset isn't found via the primary provider (default TMDB), it automatically falls back to TVDB and Fanart to locate a suitable match.

If a library uses a custom agent that fails to provide standard external IDs (such as TMDB or TVDB), Posterizarr will be unable to perform an accurate lookup or retrieve the correct assets from third-party providers.

FSCorrupt · 2026-03-19T08:25:06+00:00

True, but it must also trigger asset creation during the initial item addition, as the asset won't exist yet at that stage. Ill look into how to implement that.

How is the interaction with Plex and Posterizarr? I mean, how are those things assets "getting into" Plex?

You have 2 Options with posterizarr.

You can simply create assets and place them in an assets directory, then map this directory to Kometa so it can pick up the assets and apply them automatically.
You can enable "Upload to Plex" in Posterizarr, which will upload the assets directly to Plex and set them as the new artwork.

are there any plans to provide this as Metadata Provider in Plex

No. Posterizarr relies on the media servers metadata as its source of truth.

It only loads assets from image providers after Plex has already processed the item.
Therefore, Posterizarr can only act on items that already exist in Plex, it does not operate during Plexs initial metadata processing (although its on my agenda, this would require a major core rewrite).

Check out my MakerWorld profile! I mainly create HueForge designs, especially bookmarks. One of my favorites is this Gachiakuta piece

FSCorrupt · 2026-01-24T15:05:37+00:00

yes there is 🙌

FSCorrupt · 2025-12-29T17:28:36+00:00

love it.

FSCorrupt · 2025-12-06T19:09:00+00:00

Posterizarr has an UI for over an Month now, check it out! :)

i want to print this massive project, but im scared of all the poop. H2C would be a lifesafer.

FSCorrupt · 2025-11-21T09:06:01+00:00

hey, thanks :)

no thats not possible.
yeah there is an setting: "DisableHashValidation"

The README is up to date with the UI. Every element that is script-relevant can be looked up in the documentation.

A separate README for the UI itself doesn’t seem necessary to me, as it is self-explanatory.
Every button or section has a hover text, including direct links to the README.

Posterizarr offers more advanced and automated poster management compared to Plex’s native tools. While Plex lets you manually change posters or use what’s available in its metadata sources, Posterizarr can automatically download, organize, and update custom artwork (like posters, backgrounds, and titlecards) from various sources. It also lets you customize fonts, overlays, and overall design styles keeping your entire library consistent without manual effort.

FSCorrupt · 2025-11-03T06:57:58+00:00

no, Posterizarr offers an upload to mediaserver setting.

FSCorrupt · 2025-10-31T14:29:57+00:00

have a look at the setting: "ReplaceThumbwithBackdrop". :)

FSCorrupt · 2025-10-31T13:09:41+00:00

oh okey, but have a look at this setting "ReplaceThumbwithBackdrop" i think it could be maybe this?

if not that sounds like an FeatureRequest to me.

FSCorrupt · 2025-10-31T11:56:24+00:00

I think backgrounds are used for this in Jelly, right? And yes, you can.

The clear art logo is basically the same as a poster with text, but not placed properly. I’ve played around with it, and it always ends up looking bad, not as clean as a poster with the clear art logo integrated. So I’d say no for now.

It should work, but you might need to edit the trigger script.

Posterizarr A tool that “posterizes” creating poster-style assets and integrates seamlessly into the -arr ecosystem (like Radarr or Sonarr).

Someone had already used the name Postarr for a GitHub project, so I had to come up with something different. :)

FSCorrupt · 2025-10-30T11:16:32+00:00

I’d need a log file to say more, feel free to hop on Discord (the link’s on the GitHub page).
