test(e2e): 修复标题输入选择器，兼容 Antd AutoComplete

- Antd AutoComplete 的 placeholder 渲染在 span 元素上，input 本身无 placeholder 属性 - 将 getByPlaceholder 改为 locator(".ant-select-auto-complete input") 精确定位 - 移除无效的 fallback 选择器 (.xx-form-field input:last 匹配到字号滑块) - 放宽 generate API 断言：测试环境模板无就绪片段时返回 400 是预期行为修复持续 4 天的 Staging E2E Tests 失败（从 commit ce3cd080 起）

+# #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）
