# 平台规格导出 · Platform Spec Export

一条母版(建议 1080×1920、30fps)→ 多平台文件 + `export_report.json`。脚本:`scripts/export_platform.py`。

> Part of [ecommerce-video-skills](https://github.com/xianyu110/ecommerce-video-skills)
>
> ⚠️ 平台规则经常变。下表是**稳妥的推荐编码**,不是官方上限;时长、文件大小、是否允许外链/价格信息等,上传前请在各平台官方上传页/商家后台确认。

## 预设 Presets

| `--platform` | 输出 | 用途 / 需确认 |
|---|---|---|
| `douyin` | 1080×1920 · 30fps | 抖音信息流/商品视频;上限以创作者中心为准 |
| `tiktok` | 1080×1920 · 30fps | TikTok 信息流 |
| `tiktok-shop` | 1080×1920 · 30fps | TikTok Shop 商品/联盟视频;以 Seller Center 为准 |
| `channels` | 1080×1920 · 30fps | 视频号;信息流预览可能裁切,主体和标题放中部 |
| `xiaohongshu` | 1080×1440(3:4) | 小红书信息流最占屏 |
| `taobao-main` | 1080×1080(1:1) | 淘宝/天猫主图视频(3:4 用 `taobao-3x4`);以千牛后台为准 |
| `amazon` | 1920×1080(16:9) | Amazon 商品视频;以 Seller Central 为准 |
| `square` | 1080×1080 | Shopee / Lazada / 通用信息流 |

编码统一:H.264 High、yuv420p、CRF 20 + 码率上限、AAC 160k 48 kHz、`+faststart`(边下边播)。

## 步骤 Steps

```bash
python scripts/export_platform.py out/master.mp4 --platform douyin tiktok-shop channels xiaohongshu taobao-main amazon
python scripts/export_platform.py out/master.mp4 --platform all --outdir out/export
python scripts/export_platform.py out/master.mp4 --platform xiaohongshu --mode crop --focus-y 0.4   # 裁切而非模糊填充
python scripts/export_platform.py out/master.mp4 --safe-preview out/safe.png                    # 安全区叠加图
```

1. 母版先按 9:16 做好(字幕已在安全区内)。
2. 选择转换方式:`blur`(默认,保留完整画面,上下/左右模糊填充)或 `crop`(填满画面,会裁掉边缘 → 检查字幕和商品)。
3. 读 `export_report.json`:分辨率、时长、大小、注意事项。
4. 9:16 → 16:9 时字幕会变小,重要平台建议用 `assemble.py --size 1920x1080` **重新渲染**而不是转码。

## 安全区 Safe zones

`--safe-preview` 在一帧上叠加三块经验区域(顶部状态栏 ~9%、右侧按钮栏 ~15% 宽、底部文案/商品卡 ~22%)。这些是经验值,**最终以真机预览为准**。

## 提示词模板 Prompt template

```text
我有一条 {时长} 秒、{分辨率} 的带货母版视频,要发到 {平台列表}。
请给出:每个平台用哪个 --platform 预设、用 blur 还是 crop、需要去官方后台确认的事项(不要编造具体上限数字)。
```

## 检查清单 Checklist

- [ ] 每个导出文件都能本地播放,音画同步
- [ ] crop 模式下字幕/商品没被裁
- [ ] 视频号/小红书封面另做 3:4(见 `cover-title-ab`)
- [ ] 已在官方后台确认时长与大小限制

## 常见问题与修复 Failure fixes

| 问题 | 修复 |
|---|---|
| 上传后糊 | 平台二压;保证源 1080p、码率不要过低,避免大面积细噪点/渐变 |
| 上传失败:文件太大 | 降低 `maxrate`(如 `8M`)或缩短时长 |
| 横版字幕太小 | 用 `assemble.py --size 1920x1080` 重新渲染 |
| 黑边 | 用默认 `blur` 模式或 `crop` |
