## What it does

Makes FLUX 3 video look archival or period-accurate by naming a recording format instead of a mood and describing that format's specific degradation and artifacts. It adds templates, a control probe to prove a style word works, and montage and review guidance.

## Use when

- A VHS, film-stock or newsreel look
- Period or found-footage scenes

## Install

- Claude Code: `/plugin marketplace add black-forest-labs/skills && /plugin install flux-3-video@black-forest-labs`
- Codex: `npx skills add black-forest-labs/skills --skill flux-3-archival-formats -a codex`
- Cursor: `npx skills add black-forest-labs/skills --skill flux-3-archival-formats -a cursor`
- Gemini CLI: `npx skills add black-forest-labs/skills --skill flux-3-archival-formats -a gemini-cli`
