Plex has changed its primary metadata source for movie posters.

Posters that you have manually selected or uploaded will not be affected by this change.

Plex says that its new metadata source will improve the quality of movie posters.

In most cases, this change will be “imperceptible.”

The name of this new metadata source is also a mystery.

Again, we don’t know.

The new metadata source will also serve movie artwork for Plex Discover and the Plex ad-supported video library.

It may take a few days for the new metadata source to complete its rollout.

If you don’t use the default Plex Movie agent, you won’t see any changes.
