中国开发者开源 lanshu 数字人口播工具，脚本与照片即可本地生成含配音、口型同步与字幕的竖屏视频。
THIS IS FUCKING INSANE. a Chinese developer just released a FREE tool that can turn one script and one photo into a complete video with a presenter. it was just released and already has 26,000 stars. it’s called "lanshu-create-ai-presenter-video". here's how it works: you give it a script and a presenter photo you have permission to use. the AI creates the voice, makes the presenter talk, and matches the lips to the audio. then it adds the subtitles, creates the cover, checks that everything is synced properly, and gives you the finished video with a quality report. the final video is 9:16, 1080x1920, 30fps, and 45-75 seconds long. and the crazy part is it does all of this in one run on your own computer. if you make short form content, save this before you make your next video. will be dropping more free tools soon, so bookmark
是什么 据推文介绍，这是中国开发者开源的本地口播视频生成工具 lanshu-create-ai-presenter-video，宣称发布不久即获 26,000 star。输入一份脚本和一张有使用授权的人像照片，即可单次运行产出 9:16、1080x1920、30fps、45-75 秒的成片。
核心设计 端到端流水线：AI 生成配音、驱动人像开口并做口型对齐，随后自动添加字幕、生成封面、校验音画同步，最终输出附带质量报告的成片；全程在自己电脑上一次跑完，不依赖云端服务。
关键洞察 它把“脚本→成片”压缩为一次本地运行，将配音、口型、字幕、封面、质检全部自动化，直接命中短视频口播内容的高频生产痛点；配合“免费 + Star 数”的传播话术，是典型的开源工具冷启动打法，也反映了数字人/口播生成赛道的内卷程度。
边界与风险 被引用的 X 文章无法加载，26,000 star、免费与实际效果均无法核实；人像驱动涉及肖像授权与深度伪造风险；单条推广推文带有明显的 bookmark 引流话术，实际生成质量、硬件门槛与长脚本表现都需自行验证，不宜仅凭 Star 数采信。对关注 Agent 工程与流水线编排的工程师而言，值得研究的价值点在于其端到端编排与质检环节的设计思路。
