+
+## 场景一致性
+
+视频制作的「场景固定设定」位于镜头衔接上方。同一场景 ID 的分镜（包括跨集复用）共用空间、固定陈设、时间和光源；没有单独固定设定时直接采用已有场景描述。编辑保存用于后续生成，不改写原分镜或旧视频。灯光开关、移动道具等剧情变化应记录在镜头起止状态中，换机位保持物理空间关系而非屏幕左右不变。
+
+后端从绑定场景读取环境，单独加入每个视频/分镜图片请求，避免只写人物表演而遗漏背景。普通参考模式补带场景图并保留现有图片编号；尾帧接续和 VDN 高清沿用视频参考帧，同时保留环境文字。MiniMax H3 的环境描述翻译为英文，台词保持原文。缺失/失效的场景、超出模型参考图数量会在换卡取消旧任务之前报错；任务记录保存当时场景设定快照。
+
+场景图应与文字设定一致。文字与参考图可减少漂移，但不保证生成画面逐像素一致；连续动作可使用已有「尾帧接续」。角色三视图、道具白底图不加入场景约束。没有场景图时页面明确提示仅有文字约束。
+
+回归验证：`integration-work/test_scene_continuity.py` 使用独立 SQLite 和本机模拟模型服务，覆盖实际请求体、参考编号、换卡、跨集、转场、尾帧、高清、图片与数据持久化；设置 `SCENE_UI_TEST=1` 可同时验证页面保存和刷新。需先构建桌面后端及前端，并具备现有 Electron 测试运行环境。
+
+## LTX / Wan 分镜首帧
+
+视频制作选择 LTX-2.3、LTX-2.3-Text-Preserve 或 Wan2.2-I2V 后，点击生成会先使用顶部选定的 Qwen Image 2.1 图片配置制作完整画面。绑定的场景、人物、道具全部参与：6 个以内一次提交；更多素材以「上一轮合成图 + 最多 5 个新增素材」继续融合，保留每轮结果与素材清单。缺少参考图片会明确报错，需先补图；不再只选第一张场景图。
+
+图片显卡跟随顶部图片配置，视频显卡跟随当前镜头设置。首帧准备完成后才提交视频；开启尾帧接续时，前镜头末帧也加入融合。右侧「分镜首帧」显示最终画面、素材清单和图片模型；输入未变时重试视频复用首帧，也可点击「重做首帧并生成视频」。修改分镜或绑定素材后重新合成，生成中修改会阻止旧首帧提交视频。
+
+准备首帧期间可取消父视频任务，同时取消其当前图片任务；重启继续跟踪已提交图片，不重复生成。首帧失败不会提交视频。中间图与最终图进入任务历史，不覆盖人物原图、场景原图或旧视频。全参考图流程减少身份与环境漂移，生成结果仍需检查；跨多个融合轮次可能出现误差。
+
+回归脚本：`integration-work/test_composed_first_frame.py`，设置 `COMPOSE_UI_TEST=1` 同时检查真实界面。使用隔离数据库和本机模拟服务，覆盖 15 张素材、GPU 路由、尾帧衔接、失败、取消、重启与避免重复提交，不消耗真实模型算力。
+
+## 英文视频提示词
+
+新拆分镜、重新生成视频提示词时同时产出中文和英文。视频提示词下方可查看、编辑或重新翻译英文；「补齐英文」仅翻译已有中文提示词，不重新拆分镜、不生成视频。中文修改后旧英文标记为待更新。
+
+MiniMax-H3 系列（含加速版、VDN 高清）提交前自动补齐或更新英文，并翻译镜头衔接约束。对白原文、@/# 素材标记和时间段通过校验后才提交，中文台词不改为英语；语音标记采用 H3 可识别的 `says:` / `Dialogue:`。翻译失败时不提交新视频，也不取消原任务。任务记录保存实际英文请求文本并显示「英文提交」。已生成视频不自动重跑。
+
+## 镜头衔接
+
+视频制作中、视频提示词上方的「镜头衔接」面板提供三种模式：
+
+- **独立镜头 / 转场**：不依赖前段，适合换场景、时间跳跃或开场。
+- **状态承接**：将前镜头结束状态与本镜头起止状态加入生成约束；允许换角度，仍使用本镜头的资产参考图。
+- **尾帧接续**：同场景连续动作。等待前段完成，从所选视频结束前 0.05–3 秒提取画面，再向选定 GPU 提交。当前本地 MiniMax-H3、MiniMax-H3-Hybrid 直接使用单张尾帧；LTX-2.3 和 Wan2.2-I2V 将尾帧与全部绑定素材融合后使用新首帧。不与参考音色混用。
+
+来源默认为按集号、镜号排序的前一镜，也可选择本项目更早的镜头。不能引用未来、自身、其他项目或已删除的镜头。第一镜、转场需用独立模式。拆分镜工具会读取上一集结尾剧本及最后三个分镜；起止状态是文字设定，不代表系统已经识别或审核了成片画面。
+
+已有分镜升级后保持原模式、原视频，不会自动重新生成。新拆分时 Agent 会填写起止状态并选择衔接方式；旧分镜可在面板中补填后保存。尾帧预览仅提取画面，不生成新视频。前镜头失败时下游保持等待；可取消等待，或先处理前镜头。等待中的任务可重启恢复，并保留原模型与显卡选择。
+
+前镜头版本或起止设定改变后，已生成的下游视频显示核对提示，旧版保留，不自动重跑。依赖链按顺序提交，独立镜头仍可多卡并行。VDN-H3 高清制作仍使用其参考图工作流，不支持固定首帧接续。
+
+## 视频进度与预计耗时
+
+分镜拆分按每批最多 4 个段落校验中文、英文、时间轴和素材绑定，全部通过后一次性替换旧分镜。取消、超时、重启或校验失败均保留旧分镜；拆分期间修改剧本或原分镜，会阻止旧结果覆盖新编辑。
+
+没有上传音色不影响拆分：生成草稿中误加的角色音色引用会改回普通人物引用；真实音色和对白原文保留。素材引用中的多余类别前缀会统一为实际资产名称。对白提到“血红文字”等内容不再误判为画面画字；实际要求画字仍会退回修正。连续三轮没有保存进展会停止并显示具体错误，诊断信息保存在本地任务状态中。
+
+拆分任务按原文场次逐场运行，为每段原文分配来源编号，当前场次覆盖完成后才进入下一场。每场核对来源编号、按原文顺序保留的对白、最少镜头数和时长；仅出现结尾台词不能判定整集完成。预计镜头数量是节奏参考，不是固定上限；不能为了达到数量添加剧情。
+
+长台词按原文切成小段，并给出约 4.5 汉字/秒的发声时长参考。校验具体对白时间段，不允许用几秒承载几十字台词；小幅时间分配错误会同步修正中英文时间轴，超过单镜头 15 秒容量时必须继续细分。全部场次通过校验才替换原分镜。来源编号和对白校验不等于人工审片，表演、调度及动作覆盖仍需检查。旧版本过度压缩的结果会提示重新细分，不自动改写已有镜头或视频。
+
+视频预览下方、任务列表和高清制作页会显示排队、模型加载、采样、解码与编码阶段，以及已提交时长。采样步数来自对应 ComfyUI 任务的实时消息；积累足够的步速记录后显示当前采样阶段的剩余时间区间，后续解码、编码和保存另计。
+
+整段视频耗时只参考同显卡、同工作流及规格的成功记录，不包含排队与下载；样本不足时不报估算。采样完成不代表成片完成，连接中断或数据过期会隐藏旧估算。进度读取不会取消、重新提交或改换显卡。
+
+服务器的进度扩展源文件为 `integration-work/comfy_progress.py`，由 `install_comfy_progress.py` 备份后嵌入现有适配器；无需重启 ComfyUI。图片、视频及私有配置仍不进入 Git。
+
+## 下载后自动清理 ComfyUI 视频
+
+本地视频任务（包括高清版）成功下载后，先完整解码校验、写入磁盘并保存到项目，才发送带文件长度和 SHA-256 的清理确认。服务器再次核对实际交付的视频内容，从该任务的历史记录中定位唯一输出，仅删除对应视频文件和该条 ComfyUI 历史记录。火宝中的本地成片、海报、历史版本、人物和场景参考图保持可用。
+
+清理失败单独重试，不把已完成的视频改成失败；重启后继续确认，任务列表显示等待清理或已清理。未收到本地下载确认、正在运行、被其他任务引用、文件校验不符或路径不明确的任务不删除；既有已完成任务不批量追溯清理。
+
+服务端运行 `comfy_video_cleanup.py` 用户服务，只消费两个私有桥接器保存的确认记录，没有新增网络监听，不重启 ComfyUI。先记录精确文件标识再删除，异常退出后可继续完成同一条记录。`test_video_cleanup_delivery.py`、`test_video_cleanup_api.py` 和 Linux 隔离测试 `test_comfy_video_cleanup.py` 分别验证本地下载、确认接口及删除范围。
+
+## 取消任务
+
+打开右上角「任务」，在对应图片或视频记录上点击「取消任务」。只停止这一条任务，不影响其他镜头、其他显卡任务或已有素材。等待前镜头的任务也可以直接取消。
+
+已提交的任务需要收到对应节点的取消确认，才会显示「已取消」；未收到回执时显示「正在等待显卡确认」，可重试取消，重启后仍会跟踪原任务。提交中尚无任务编号、已经完成或正在保存结果的任务不提供取消按钮。已取消任务单独统计，不计入失败数量。
