为什么值得看
SMPTE 将其音视频工程标准从付费墙后释放出来，任何人可免费访问。对 AI 视频生成、多模态模型开发者而言，这意味着终于有了官方技术规范来对齐输出格式，减少兼容性试错成本。
编辑判断
AI 视频生成领域长期存在'能生成但不对齐'的问题——模型输出的帧率、色彩空间、HDR 元数据往往与主流播放平台不兼容，团队需要反复调试。SMPTE 标准免费开放后，Runway、Pika 这类工具可以直接对标 ST 2084（PQ）、ST 2094（动态元数据）等规范，减少下游工程适配。
更深层的影响在版权与合规层面：SMPTE 标准也是内容溯源水印（如 ST 2067 系列）的技术基础，随着欧盟 AI Act 对生成内容标识的要求落地，免费获取这些标准会降低合规门槛。做 AI 视频基础设施的团队，建议把 SMPTE 规范纳入技术债清理清单。

I don't understand why any standards body would consider not doing this as a default.
I don't think the benefits of charging for your work are mysterious. It's reasonable to believe that certain works should not be behind paywalls, but not understanding is kind of a confusing stance.
If your entire goal is to create a standard... it seems like giving anyone access to the materials needed to _adhere_ to said standard is prerequisite. Unless the goal is not to create standards, but instead to control access to said standard.
