将 GUI、科研软件或 agent 屏幕录制剪成清楚连贯的演示视频；处理静止与周期等待、分屏悬浮、缩放跟随、日志对话、中文字幕、背景音乐与现成旁白；支持图片堆叠展开、拉远揭示、信息流动画、精确帧预算和无损母版，附可配置 FFmpeg/Python 工具及合成素材验收。.
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
# 屏幕演示视频剪辑与包装 ## 交付边界 - **面向录屏后期。** 用已有视频、截图和日志完成剪辑、镜头编排与视听包装；不把任务扩大成重新操作软件、生成科研结果或自动下载素材。 - **先识别时间轴。** 区分原始录屏、已确认的剪辑版、包装版、最终带声音版。剪辑以原片和源时间 EDL 为准；只加音频时复制已确认视频流。 - **参数可迁移。** 分辨率、分割线、ROI、网格映射、字体、品牌、阶段文案和模型显示名都由项目配置提供。示例数值是起点，不是另一份录屏的正确答案。 - **已有授权继续执行。** 保留原素材，导出新文件；不自动覆盖输入。不要为普通可逆的剪辑反复请求确认。发布、外传日志或调用付费语音服务须在用户授权范围内。 ## 工作流 1. **探测与约束：** 检查流、时长、帧率、实际画面尺寸、音轨、DPI/鼠标坐标来源及播放器字幕。明确用户要缩短等待、视觉展示、实质操作还是配音；默认不改变已确认的操作顺序。 2. **剪辑：** 低分辨率分析静止/周期，只生成候选 EDL；保留必要的思考停顿、输入变化与真实第一段鼠标运动。按 [02](references/02_idle_and_periodic_cleanup.md) 复查周期相位与光标遮罩。 3. **叙事与构图：** 需要解释背景时先安排标题、数据与难点，再进入真实操作；图片堆叠、展开与拉远见 [07](references/07_storyboard_and_animation.md)。分开定义面板位置和内部取景；日志可常驻或退场，按要求配置。相邻操作合成少量特写，画面大变时回全景。 4. **对话与字幕：** 日志先映射到成片时间；消息按时间追加，退场只移动面板，不截断播放器。字幕面向观众解释行为。仅展示获准公开的正文、原始截图与独立结构化工具卡片；工具参数显式白名单，不展示隐藏推理或完整 API 响应。 5. **音频：** 按要求加入背景音乐或现成旁白，测响度、做淡入淡出，必要时用旁白侧链压低音乐。只要求配乐时不擅自生成配音；本工具不包含 TTS/声音克隆接口。 6. **时长与验收：** 精确总时长先分配整数帧，固定介绍/结果/品牌停留，剩余预算留给操作段；来源和一次编码流程见 [08](references/08_exact_timing_and_source_quality.md)。先出关键静帧，再出包含转场的短视频，最后完整导出。静帧正常不证明动态合成正常；必须检查实际成片尺寸、切口、文字、消息时序、音画时长和全片解码。 ## 核心经验 - **真实开场：** “移动前静止几秒”要保留移动前的原始画面与完整运动，不能冻结已经移动后的首帧代替。 …

How to install
mdr add black-yt/skills/screen-demo-video-editing@sha256:76d79a09d51e5020The line at the top of this page pins the label git:20261105.49d2270, 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.
