# Pure Tune Studio / 纯音工坊 Generate an original instrumental-music video from a reference track. The workflow goes from audio analysis to Suno generation to a JianYing draft and publish-ready copy. 从一首参考曲生成原创纯音乐视频，流程覆盖音频分析、Suno 生成、剪映草稿和发布文案。 ## First use / 首次使用 Run `python scripts/install.py` to install Python dependencies and check that `ffmpeg`/`ffprobe` are available. Configure paths with the `PURETUNE_*` environment variables when the defaults do not match the local machine. 运行 `python scripts/install.py` 安装 Python 依赖，并检查 `ffmpeg` / `ffprobe`。当默认路径与本机不一致时，用 `PURETUNE_*` 环境变量配置路径。 ## Start here / 开始前 Before doing any work, ask the user three questions. 开始工作前，先问用户三个问题。 1.

Should the platform copy be generated by the skill, or imitated from a user-provided template? 文案由技能生成，还是根据用户提供的模板仿写？ Background image rules / 背景图规则： - User-provided image: use it directly, do not validate its resolution. 用户提供的图片：直接使用，不校验分辨率。 - Auto-generated image: produce a 1920x1080 image using the analysis of the recorded songs as the image prompt. 自动生成图片：以录音歌曲的分析结果作为图像提示词，生成 1920×1080 图片。 Copy rules / 文案规则： - If the skill generates the copy, use generic music-channel conventions. Do not reuse any personal copywriting style from a local project. 如果由技能生成文案，使用通用音乐频道习惯，不套用任何本地项目的个人文案风格。 - If the user provides a template, imitate its struct
