-# #1197 预览生成接口方案评估
-
-## 背景
-
-智能剪辑「一键生成」流程中，第3步预览生成当前被跳过，直接进入下一步。需要实现真正的预览生成功能，让用户在正式生成前能看到效果预览。
-
-## 现状分析
-
-### 现有生成链路
-
-```
-API 触发生成 → GenerationTask入库 → Celery异步任务 → UnifiedRenderService渲染 → OSS上传 → 更新状态
-```
-
-**关键节点：**
-1. **API层**：`POST /generation-tasks` 或 `POST /templates/{id}/generate` 触发生成
-2. **任务调度**：Celery task `worker.generate_video`
-3. **渲染引擎**：`UnifiedRenderService`（统一渲染引擎，已接入9个效果层）
-4. **输出配置**：默认 720p (1280x720)，支持 `resolution` 字段自定义
-5. **产物存储**：`GeneratedVideo` 表记录，OSS 存储视频文件
-
-### 已有可复用能力
-
-| 能力 | 位置 | 是否可复用 |
-|------|------|-----------|
-| 任务创建与状态管理 | `GenerationTask` + `CreateGenerationTaskUseCase` | ✅ 是 |
-| 素材下载与预处理 | `_download_video_assets` / `_download_voice_asset` | ✅ 是 |
-| 统一渲染引擎 | `UnifiedRenderService` | ✅ 是 |
-| 分辨率配置 | `resolution` 字段已支持 | ✅ 是 |
-| 混音与后处理 | `_render_video` 内流程 | ✅ 是 |
-| OSS 上传与查重 | `_upload_and_dedup` | ✅ 是 |
-| 进度追踪 | `append_log` / `progress` 字段 | ✅ 是 |
-
-## 方案对比
-
-### 方案A：复用现有生成链路 + is_preview 标记（推荐）
-
-**思路**：在现有 GenerationTask 上加 `is_preview` 标记，预览生成走完整链路但参数降级。
-
-**改动点：**
-1. **数据模型**：`GenerationTask` 加 `is_preview: bool` 字段（默认 false）；`GeneratedVideo` 加 `is_preview: bool`
-2. **API 层**：生成接口加 `is_preview` 参数，预览任务不计入配额
-3. **渲染参数**：预览模式下自动调整
-   - 分辨率：480p (854x480)
-   - 时长：限制前 15 秒（或模板第一个片段）
-   - 码率：降低至 1.5Mbps（正式 4Mbps）
-   - 效果层：跳过高级转场/粒子特效等耗时效果
-4. **任务调度**：预览任务走低优先级队列（或复用现有队列，标记优先级）
-5. **前端对接**：预览生成结果带 `is_preview=true` 标记，前端展示"预览"标签
-
-**优点：**
-- 代码复用率 90%+，改动最小
-- 与正式生成逻辑一致，预览效果真实可信
-- 进度查询、结果展示等功能直接复用
-- 后续可平滑升级：预览满意后一键转正式生成
-
-**缺点：**
-- 需要区分预览和正式任务，避免数据混淆
-- 预览任务和正式任务竞争同一队列资源（可后续优化为独立队列）
-
-**开发量估算**：2-3 天
-- 数据模型 + 迁移：0.5 天
-- API 层改造：0.5 天
-- 渲染参数降级：1 天
-- 测试 + 联调：1 天
-
----
-
-### 方案B：新建独立预览接口 + 轻量渲染逻辑
-
-**思路**：新建独立的预览生成接口，使用简化的渲染逻辑（如只拼接素材+基础配音，跳过大部分效果）。
-
-**改动点：**
-1. 新增 `PreviewTask` 数据模型
-2. 新增 `POST /api/v1/preview/generate` 接口
-3. 新增独立的 Celery task `worker.generate_preview`
-4. 简化渲染流程：只做素材裁剪+拼接+配音，跳过转场/滤镜/字幕特效等
-
-**优点：**
-- 完全隔离，不影响正式生成链路
-- 可以做极致优化，预览生成速度快
-- 数据模型清晰，不会混淆
-
-**缺点：**
-- 代码重复率高，两套生成逻辑维护成本翻倍
-- 预览效果与正式生成可能不一致（效果层差异）
-- 前端需要对接两套接口
-- 无法从预览升级为正式生成（需重新走完整流程）
-
-**开发量估算**：4-5 天
-- 数据模型 + 接口：1 天
-- 简化渲染逻辑：2 天
-- 测试 + 联调：1-2 天
-
----
-
-### 方案C：图片预览（首帧/关键帧截图）
-
-**思路**：不生成视频，只生成几张关键帧的预览图片。
-
-**优点：**
-- 生成速度极快（秒级）
-- 资源消耗小
-
-**缺点：**
-- 预览效果差，用户无法感知动态效果
-- 无法验证配音、转场、节奏等时间维度的效果
-- 用户体验不佳，不如"真预览"有说服力
-
-**开发量估算**：1-2 天
-
----
-
-## 推荐方案：方案A（复用现有生成链路）
-
-### 核心理由
-
-1. **效果保真**：预览和正式生成用同一套渲染引擎，效果一致，用户信任度高
-2. **开发效率**：90% 代码复用，2-3 天可上线
-3. **可扩展性强**：后续可加「预览转正式」「低分辨率快速预览」等增强功能
-4. **维护成本低**：一套生成逻辑，bug 修复和新功能同时生效
-
-### 详细设计
-
-#### 1. 数据模型变更
-
-```python
-# GenerationTask 新增字段
-is_preview: bool = False
-"""是否为预览生成"""
-
-preview_of: str = ""
-"""预览对应的正式任务 ID（或反向关联）"""
-
-# GeneratedVideo 新增字段
-is_preview: bool = False
-"""是否为预览视频"""
-```
-
-**迁移**：alembic 新增 migration，两个表各加 1-2 个字段。
-
-#### 2. API 层
-
-```
-POST /api/v1/generation-tasks
-  Body 增加 is_preview: bool = false
-  
-POST /api/v1/templates/{id}/generate
-  Query 增加 is_preview: bool = false
-```
-
-**配额处理**：预览生成不计入用户配额，不占用生成次数限制。
-
-#### 3. 渲染参数降级
-
-| 参数 | 正式生成 | 预览生成 |
-|------|---------|---------|
-| 分辨率 | 720p (1280x720) | 480p (854x480) |
-| 码率 | 4 Mbps | 1.5 Mbps |
-| 时长 | 完整时长 | 前 15 秒（或第一段） |
-| 帧率 | 30 fps | 24 fps |
-| 转场效果 | 完整转场 | 仅淡入淡出（或简单切） |
-| 特效滤镜 | 全部启用 | 跳过粒子/光效等高级效果 |
-| 字幕 | 完整渲染 | 正常渲染（字幕是核心信息） |
-| 配音 | 完整混音 | 正常混音（配音是核心信息） |
-
-**实现方式**：在 `_render_video` 或 UnifiedRenderService 入口处，根据 `is_preview` 标记调整渲染配置。
-
-#### 4. 任务调度
-
-- 初期复用现有队列，预览任务正常排队
-- 后续如需优化，可拆分独立预览队列（低优先级）
-- 预览任务可设置较短超时时间
-
-#### 5. 前端对接
-
-- 调用生成接口时传 `is_preview=true`
-- 结果列表中预览视频带「预览」标签
-- 预览满意后可一键「升级为正式生成」（重新触发全分辨率生成，可复用素材下载缓存）
-
-### 实施步骤
-
-**Phase 1（MVP，2天）：**
-1. 数据模型 + 迁移
-2. API 层支持 is_preview 参数
-3. 渲染分辨率降级（480p）
-4. 不计入配额
-5. 基础测试
-
-**Phase 2（优化，1-2天）：**
-1. 时长限制（前15秒）
-2. 效果层降级（跳高级效果）
-3. 预览任务低优先级队列
-4. 预览转正式生成功能
-
-## 与前端对齐点
-
-1. 预览生成的触发时机（第3步自动生成？用户点击才生成？）
-2. 预览时长是固定15秒还是完整但低清？
-3. 是否需要「预览转正式生成」功能
-4. 预览视频的展示形态（和正式视频一样还是有特殊UI）
-
-## 风险与注意事项
-
-1. **数据混淆**：确保统计、计费、列表展示时正确区分预览和正式任务
-2. **存储成本**：预览视频也占 OSS 空间，可设置自动清理（7天后自动删除）
-3. **用户预期**：要明确告诉用户这是预览，效果和正式生成一致但清晰度低
-4. **并发压力**：如果用户频繁生成预览，可能增加系统负载，需要限流

-# #1197 预览生成接口技术方案（v2）
-
-> 更新说明：v2 新增「多版本预览生成」能力，支持一个模板生成多个不重复的预览视频，左侧列表展示，用户可挑选满意的版本转正式生成。
-
-## 1. 背景与目标
-
-**现状**：智能剪辑「一键生成」第3步预览生成被跳过，用户直接进入正式生成，缺少效果预览环节。
-
-**目标**：
-1. ✅ 实现真正的预览生成（低分辨率快速出片）
-2. ✅ **支持生成 1~N 个不重复的预览版本**（默认 3 个），左侧列表展示
-3. ✅ 预览满意后可一键转正式生成（复用素材下载缓存）
-4. ✅ 不计入用户配额，不占用正式生成次数
-
----
-
-## 2. 现有生成链路分析
-
-### 2.1 链路总览
-
-```
-API 触发生成 → GenerationTask入库 → Celery异步任务
-  → 下载素材 → 构建plan/clips → UnifiedRenderService渲染
-  → 混音后处理 → OSS上传 + 查重 → 更新状态
-```
-
-### 2.2 决定视频差异的变量
-
-要做"多个不重复版本"，先分析哪些环节可以引入变化：
-
-| 变量 | 当前行为 | 能否引入变化 | 影响程度 |
-|------|---------|------------|---------|
-| 素材选择 | 按 asset_ids 顺序全用 | ✅ 可随机选择子集/不同组合 | 大 |
-| 素材排序 | 按 asset_ids 顺序 | ✅ 可 shuffle 重排 | 大 |
-| 配音选择 | 固定 voice_library_id | ✅ 可选不同音色 | 中 |
-| 标题选择 | 固定 title_ids 或随机选 | ✅ 可选不同标题 | 中 |
-| BGM | 固定 bgm_config | ✅ 可选不同BGM | 小 |
-| 转场效果 | 模板固定 | ✅ 可随机化转场类型 | 小 |
-| 播放速度 | 模板固定 | ✅ 可微调速度 | 小 |
-| 分辨率/码率 | 固定 | ✅ 预览可降级 | 不影响内容 |
-
-### 2.3 可复用能力
-
-- 任务创建与状态管理：`GenerationTask` + `CreateGenerationTaskUseCase`
-- 素材下载与预处理：`_download_all_assets`
-- 统一渲染引擎：`UnifiedRenderService`
-- 分辨率配置：`resolution` 字段已支持
-- 批量任务：`batch_id` 字段已存在（可用于预览组）
-
----
-
-## 3. 总体方案：复用现有链路 + 多变体引擎
-
-**核心思路**：沿用 v1 的"复用现有生成链路 + is_preview 标记"方案，在此基础上增加「多版本生成」能力。
-
-**架构**：
-```
-预览生成请求（count=N）
-    ↓
-创建预览批次（preview_batch）
-    ↓
-变体引擎生成 N 个变体参数（variation seed + 参数组合）
-    ↓
-为每个变体创建 1 个 GenerationTask（is_preview=true）
-    ↓
-N 个 Celery 任务并行执行（走现有生成链路，参数降级）
-    ↓
-N 个结果汇聚，前端左侧列表展示
-```
-
----
-
-## 4. 详细设计
-
-### 4.1 数据模型变更
-
-#### 4.1.1 GenerationTask 新增字段
-
-```python
-# 现有字段保留，新增：
-is_preview: bool = False
-"""是否为预览生成"""
-
-preview_batch_id: str = ""
-"""预览批次 ID（同批次的 N 个预览共享一个 batch）"""
-
-variant_seed: int = 0
-"""变体种子，用于控制随机化行为（素材选择、排序、转场等）"""
-
-variant_params: dict = field(default_factory=dict)
-"""变体参数快照（记录本次使用了哪些素材、标题、配音等，可追溯）
-   {
-     "asset_ids": [...],      # 实际选用的素材子集
-     "title_id": "",         # 选用的标题
-     "voice_id": "",         # 选用的配音
-     "transition_style": "", # 转场风格
-     "bgm_track": "",        # BGM 音轨
-   }
-"""
-```
-
-#### 4.1.2 GeneratedVideo 新增字段
-
-```python
-is_preview: bool = False
-"""是否为预览视频"""
-
-preview_batch_id: str = ""
-"""所属预览批次"""
-
-variant_index: int = 0
-"""在批次中的序号（0, 1, 2...）"""
-```
-
-#### 4.1.3 迁移方案
-
-alembic 新增 migration，两个表各加 4 个字段，默认值为空/false，无数据回填成本。
-
----
-
-### 4.2 变体引擎（Variant Engine）
-
-**核心组件**：根据 count 和 seed，生成 N 组互不相同的生成参数。
-
-#### 4.2.1 变纬度设计
-
-| 维度 | 策略 | 说明 |
-|------|------|------|
-| **素材子集选择** | 从素材池中随机选 M 个（M=min(素材数, 模板clip数*2)） | 版本差异最大的来源 |
-| **素材排序** | 随机打乱顺序 | 影响叙事节奏 |
-| **标题选择** | 从 title_ids 中随机选 1 个 | 影响文案内容 |
-| **配音选择** | 从 voice_ids 中随机选 1 个（如有多个） | 影响听觉体验 |
-| **转场风格** | 从预设转场池中随机选 1 种 | 影响视觉过渡 |
-| **BGM 选择** | 从 bgm 列表中随机选 1 首（如有配置） | 影响氛围 |
-
-#### 4.2.2 去重机制
-
-- 同一批次内，变体参数必须两两不同（至少素材组合或排序不同）
-- 使用 `variant_seed` 保证可复现（相同 seed → 相同变体）
-- 如果素材数量不足导致无法生成 N 个不同版本，按实际能生成的数量返回
-
-#### 4.2.3 接口设计
-
-```python
-def generate_variants(
-    count: int,
-    seed: int,
-    asset_pool: list[str],        # 可用素材 ID 列表
-    title_pool: list[str] = [],    # 可用标题 ID 列表
-    voice_pool: list[str] = [],    # 可用配音 ID 列表
-    template_id: str = "",
-) -> list[dict]:
-    """
-    生成 count 组变体参数。
-    
-    每组参数包含：asset_ids（选用的素材+排序）、title_id、voice_id、
-    transition_style 等，确保两两不同。
-    """
-```
-
----
-
-### 4.3 API 层设计
-
-#### 4.3.1 预览生成接口
-
-```
-POST /api/v1/templates/{template_id}/generate-preview
-```
-
-**请求体**：
-```json
-{
-  "asset_library_id": "lib_xxx",
-  "asset_ids": ["asset_1", "asset_2", ...],
-  "title_ids": ["title_1", "title_2"],
-  "voice_ids": ["voice_1", "voice_2"],
-  "bgm_config": {},
-  "count": 3,
-  "seed": 0
-}
-```
-
-| 参数 | 类型 | 必填 | 默认 | 说明 |
-|------|------|------|------|------|
-| template_id | path | ✅ | - | 模板 ID |
-| asset_library_id | body | ✅ | - | 素材库 ID |
-| asset_ids | body | ✅ | - | 素材池（从中选子集/排序） |
-| title_ids | body | - | [] | 标题池（可选，不传则不用标题） |
-| voice_ids | body | - | [] | 配音池（可选） |
-| bgm_config | body | - | {} | BGM 配置 |
-| count | body | - | 3 | 生成几个预览版本（1~10） |
-| seed | body | - | 0 | 随机种子，0 表示随机 |
-
-**响应**：
-```json
-{
-  "preview_batch_id": "pb_xxx",
-  "count": 3,
-  "tasks": [
-    {
-      "task_id": "gen_xxx_0",
-      "variant_index": 0,
-      "status": "processing"
-    },
-    {
-      "task_id": "gen_xxx_1",
-      "variant_index": 1,
-      "status": "processing"
-    },
-    ...
-  ]
-}
-```
-
-#### 4.3.2 预览批次查询接口
-
-```
-GET /api/v1/preview-batches/{batch_id}
-```
-
-返回批次内所有预览任务的状态、结果（已完成的带 video_url）。
-
-**响应**：
-```json
-{
-  "preview_batch_id": "pb_xxx",
-  "count": 3,
-  "completed_count": 2,
-  "tasks": [
-    {
-      "task_id": "gen_xxx_0",
-      "variant_index": 0,
-      "status": "completed",
-      "video_url": "https://oss.xxx/preview/xxx.mp4",
-      "duration": 15.5,
-      "thumbnail_url": "https://oss.xxx/preview/xxx.jpg"
-    },
-    ...
-  ]
-}
-```
-
-#### 4.3.3 预览转正式生成
-
-```
-POST /api/v1/preview-batches/{batch_id}/tasks/{task_id}/promote
-```
-
-将某个预览版本升级为正式生成（复用素材缓存，重新全分辨率渲染）。
-
----
-
-### 4.4 渲染参数降级
-
-预览模式下自动调整以下参数：
-
-| 参数 | 正式生成 | 预览生成 |
-|------|---------|---------|
-| 分辨率 | 720p (1280x720) | 480p (854x480) |
-| 码率 | 4 Mbps | 1.5 Mbps |
-| 帧率 | 30 fps | 24 fps |
-| 时长 | 完整时长 | 前 15 秒（或第一段完整clip） |
-| 转场效果 | 完整转场 | 仅淡入淡出 |
-| 高级特效 | 全部启用 | 跳过粒子/光效等 |
-| 字幕 | 完整渲染 | 正常渲染 |
-| 配音 | 完整混音 | 正常混音 |
-| 输出质量 | high | medium |
-
-**实现位置**：`_render_video` 函数入口处，根据 `is_preview` 标记调整渲染配置。
-
----
-
-### 4.5 任务调度
-
-- **并行执行**：N 个预览任务并行提交到 Celery，不排队等待
-- **低优先级**：预览任务走独立队列（`preview_queue`），不抢占正式生成资源
-- **超时控制**：预览任务超时时间 5 分钟（正式 30 分钟）
-- **自动清理**：预览视频 7 天后自动从 OSS 删除，任务记录标记为 archived
-
----
-
-## 5. 前端对接要点
-
-### 5.1 交互流程
-
-```
-第2步选素材 → 第3步点击"生成预览"
-  → 显示 loading + 进度
-  → 预览陆续完成，左侧列表逐张出现
-  → 用户点击左侧不同版本，右侧预览区切换
-  → 用户选中满意版本 → 点击"正式生成"
-```
-
-### 5.2 需要对齐的接口
-
-1. **预览创建**：`POST /templates/{id}/generate-preview`
-2. **批次状态轮询**：`GET /preview-batches/{id}`（建议 2s 轮询，或走 SSE）
-3. **预览转正式**：`POST /preview-batches/{id}/tasks/{task_id}/promote`
-
-### 5.3 数据格式对齐
-
-预览视频条目结构：
-```json
-{
-  "id": "gen_xxx",
-  "variant_index": 0,
-  "status": "completed",
-  "video_url": "https://...",
-  "duration": 15.5,
-  "file_size": 2850000,
-  "thumbnail_url": "https://...",
-  "is_preview": true
-}
-```
-
----
-
-## 6. 配额与计费
-
-- 预览生成**不计入**用户配额
-- 同一模板 + 同一素材池，每天最多生成 3 次多版本预览（防滥用）
-- 单个预览批次最多 10 个版本
-
----
-
-## 7. 实施步骤
-
-### Phase 1：单版本预览（MVP，2 天）
-1. 数据模型 + 迁移（is_preview 字段）
-2. API 层支持 is_preview 参数
-3. 渲染分辨率降级（480p）
-4. 不计入配额
-5. 基础测试
-
-### Phase 2：多版本预览（3 天）
-1. 变体引擎实现（素材随机选择 + 排序 + 去重）
-2. preview_batch 批次管理
-3. 批量创建 N 个预览任务
-4. 批次查询接口
-5. 前端联调
-
-### Phase 3：预览转正式 + 优化（2 天）
-1. 预览转正式生成接口（promote）
-2. 素材下载缓存复用
-3. 独立预览队列（低优先级）
-4. 自动清理机制
-5. 完整测试 + 压测
-
----
-
-## 8. 风险与注意事项
-
-| 风险 | 影响 | 应对 |
-|------|------|------|
-| 并发预览任务过多打满 worker | 正式生成被阻塞 | 独立预览队列 + 限流 |
-| 变体生成的视频差异不够大 | 用户觉得"都一样" | 优先素材子集+排序差异，保证视觉差异 |
-| 预览视频占用 OSS 存储 | 存储成本上升 | 7 天自动清理 + 低码率 |
-| N 个版本同时下载重复素材 | 带宽浪费 | 批次内共享一次下载（Phase 3 优化） |
-| 用户预期管理 | 以为预览就是最终效果 | 明确标注"预览版"，说明分辨率差异 |
-
----
-
-## 9. 开发量估算
-
-| 阶段 | 后端 | 前端 | 合计 |
-|------|------|------|------|
-| Phase 1 单版本预览 | 2 天 | 1 天 | 3 天 |
-| Phase 2 多版本预览 | 3 天 | 2 天 | 5 天 |
-| Phase 3 转正式+优化 | 2 天 | 1 天 | 3 天 |
-| **总计** | **7 天** | **4 天** | **~7 天（并行）** |
-
----
-
-## 10. 与 v1 方案的差异总结
-
-1. **新增多版本能力**：从"生成1个预览"升级为"生成N个不重复预览"
-2. **新增变体引擎**：负责素材选择/排序/配音/标题的随机化
-3. **新增批次概念**：preview_batch 管理一组预览任务
-4. **新增 promote 接口**：预览转正式生成
-5. **独立队列**：预览不抢占正式生成资源
-6. **开发量**：从 2-3 天增加到约 7 天（后端）
