This is a “Core” video from NMIXX, uploaded to JYP Entertainment’s channel ten days before the group’s first full album arrived. It runs under three and a half minutes and carries the album’s title, Blue Valentine, in its own name.

Agencies invent their own video formats

Korean labels rarely call a promotional clip a “teaser” anymore. Each agency coins its own vocabulary — a named format that recurs across releases and becomes shorthand the fandom learns to read. “Core” is one of these house labels rather than an industry-wide term, which is why it needs no explanation on the channel and offers none to outsiders. The practical effect is that a group builds a proprietary release language: fans know roughly what kind of clip is coming from the word alone, and search results cluster under a term only that company uses. It also lets a label release far more video than a conventional teaser schedule would justify.

About this release

The video was published on 3 October 2025 and points to Blue Valentine, NMIXX’s first full-length album, scheduled for 13 October 2025 at 6pm KST. The description carries a pre-save, pre-add and pre-order link, and the copyright line is JYP Entertainment. The clip is titled after the track “SPINNIN’ ON IT”.

Watching from outside Korea

Release times are given in KST, which is nine hours ahead of GMT, so a 6pm Korean slot lands mid-morning in Britain. Uploads in a promotional run tend to appear on consecutive days, so subscribing to the channel is more reliable than checking manually.
