Extracts video frames, detects cuts/segments, selects candidate keyframes, and generates review HTML galleries. Invoke when users ask for keyframes/cuts/segmentation/storyboard screening.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 视频转关键帧（video-to-keyframes）
把用户提供的视频转成“候选帧池 → 转场/分段 → 候选关键帧集 → 复筛画廊页”，并把产物落盘到当天文件夹，方便后续分镜与生成。
## 何时调用
- 用户提供视频并说：抽帧/拆帧/关键帧/候选关键帧/镜头拆分/转场点/分段/分镜初筛
- 用户希望按固定工作流落盘，需要可复现的目录与文件（frames.json、cuts.json、segments.json、gallery.html 等）
## 依赖
- Python 3.10+
- numpy
- opencv-python
## 输入
- 视频文件路径（必填）
- 当天文件夹路径（可选，默认用视频所在目录；推荐 YYYY-MM-DD）
- 抽帧间隔（建议：30s≈1fps；变化快≈2fps）
## 输出（固定规范）
在 `<当天文件夹>` 下生成：
- `<当天文件夹>\_frames_<视频名>_<间隔>\`：候选帧池目录
- `f_*.jpg`：抽帧图片
- `frames.csv / frames.json / top_keep.json / meta.json`
- `\_keyframe_candidates\`：候选关键帧集目录
- `cuts.json`：转场点
- `segments.json`：分段与每段代表帧
- `segments_gallery.html`：分段可视化（每段1张代表帧）
- `gallery.html`：候选关键帧画廊（逐个复筛）
- `candidates.csv / candidates.json`
- `selected.txt`：人工/AI复筛后的最终候选ID（每行一个 cand_id）
- `prompt_pack.html`：复筛+提示词协作页（夜间模式，一键复制）
- `<当天文件夹>\<视频名>_拆分.txt`：汇总（转场点、分段、每段代表帧文件名）
## 一键运行（推荐）
```powershell
python .\skills\video-to-keyframes\resources\scripts\run_video_workflow.py "<视频路径>" --day-folder "<当天文件夹>" --every-seconds 0.5 --max-frames 600
```
注意：一键运行只负责产出文件，不等于完成复筛；必须打开 `gallery.html` 做人工/AI语义复筛，并把最终选择写入 `selected.txt`。
## 复筛要点（简版）
- 先看 `segments_gallery.html`：确认每段代表帧是否合理、分段是否过碎

How to install
mdr add trae-community/trae-skills/video-to-keyframes@sha256:8ffed51149dba262The line at the top of this page pins the label git:20260310.704731f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
