D11 质检与合规：机器审片、内容安全、生成内容标识与版权边界

• AI 生成的视频对外发布，合规上你必须做哪几件事？Before publishing AI-generated video, what compliance work is mandatory?

  国内高频深入#compliance#labeling#copyright

  分析过程 · 先想清楚再作答

  1. 这题在国内岗位上是硬考点，答不出「显式与隐式两类标识」基本就出局了。它同时也在考你是不是真读过原文，而不是转述别人的解读。
  2. 先给法规坐标：《人工智能生成合成内容标识办法》由四部门联合发布，自 2025 年 9 月 1 日起施行；配套的强制性国标是 GB 45438-2025《网络安全技术 人工智能生成合成内容标识方法》，同日实施。
  3. 然后给两类标识的定义，尽量贴原文：显式标识是在生成合成内容或者交互场景界面中添加的、以文字声音图形等方式呈现并可以被用户明显感知到的标识；隐式标识是采取技术措施在生成合成内容文件数据中添加的、不易被用户明显感知到的标识。**两者都要做，不是二选一**，并且服务提供者应当在文件元数据中添加隐式标识。
  4. 落地上要能说出具体做法：隐式标识写进容器元数据，用 ffmpeg 的 metadata 参数写、用 ffprobe 读回来验证，写了不读等于没写；显式标识最稳是烧进画面，但烧字依赖 ffmpeg 的 drawtext 滤镜，很多最小编译版本没有，所以要先探测能力再降级，并且把降级这件事明确打印出来。
  5. 还要补上标识之外的三条：不得恶意删除篡改伪造隐匿标识；不得生成真实人物形象；背景音乐与参考素材必须有授权来源。做微短剧还要按投资额分级审核，上线前片头标注许可证号或备案号。
  6. 可预期的追问是「元数据具体写哪些字段」。诚实的回答是以 GB 45438-2025 正式文本为准，第三方解读里流传的字段名不能直接照抄——这个回答比编一串字段名得分高得多。

  How to reason about it · think before answering

  1. In China-market roles this is a hard requirement, and missing the explicit-plus-implicit labelling pair usually ends the interview. It also tests whether you read the source text rather than someone's summary.
  2. Give the legal coordinates: the Measures for Labelling AI-Generated Synthetic Content, issued jointly by four authorities, in force from 1 September 2025, with the mandatory national standard GB 45438-2025 on labelling methods taking effect the same day.
  3. Then define both labels close to the source text. An explicit label is added in the content or the interaction interface, presented as text, sound or graphics, and clearly perceivable by the user. An implicit label is added by technical means into the content file data and is not easily perceivable. Both are required, not either-or, and providers are expected to add the implicit label in file metadata.
  4. Show you can ship it: write the implicit label into container metadata with ffmpeg's metadata option and read it back with ffprobe, because writing without verifying is the same as not writing. The explicit label is safest burned into the picture, but burning text needs ffmpeg's drawtext filter, which minimal builds often lack, so detect the capability, degrade deliberately, and log the degradation.
  5. Add the three items beyond labelling: do not maliciously delete, alter, forge or hide labels; do not generate the likeness of real people; and keep licensed sources for background music and reference assets. Short-form drama additionally needs tiered review by budget, with the licence or filing number shown in the opening.
  6. Expected follow-up: which metadata fields exactly. The honest answer is to follow the GB 45438-2025 text itself rather than field names circulating in third-party summaries, and that answer scores far better than inventing a schema.

  答题要点

  • 《人工智能生成合成内容标识办法》2025 年 9 月 1 日起施行，配套强制性国标 GB 45438-2025 同日实施。
  • 显式标识是用户能明显感知到的（文字声音图形），隐式标识加在文件数据里，两者都要做。
  • 服务提供者应当在生成合成内容的文件元数据中添加隐式标识；不得恶意删除篡改伪造隐匿标识。
  • 落地：元数据写入后必须读回验证；显式标识优先烧录，能力不足时降级并明确记录。
  • 另外三条：不得生成真实人物形象、背景音乐与素材要有授权、微短剧按投资额分级审核且片头标注许可证号或备案号。

  Key points

  • The labelling Measures take effect 1 September 2025, alongside mandatory national standard GB 45438-2025.
  • Explicit labels are clearly perceivable by users; implicit labels live in the file data. Both are required.
  • Providers add the implicit label into the content file metadata, and nobody may maliciously delete, alter, forge or hide labels.
  • In practice: verify metadata by reading it back, prefer burned-in explicit labels, and log any capability-driven degradation.
  • Also: no likenesses of real people, licensed music and source assets, and for short-form drama tiered review plus a licence or filing number in the opening.
