Live Shopping & Creator-Commerce Video-AI Decision Sheet

One-page planner: the video-AI feature catalog across two loops (live loop: captions, translation, moderation, product recognition, AI host, analytics; long-tail loop: clipping, dubbing, descriptions, multimodal search), the two lines (live: synchronous vs asynchronous placement; trust: optimization vs a regulated trust function), where the AI runs (device / media server-SFU / cloud) with WebRTC sub-second vs LL-HLS few-second delivery, the buy-now latency math (auction at -20 s HLS vs -0.3 s WebRTC; clipping ~15x compute saving), the disclosure stack (US FTC endorser + fake-review rule, EU AI Act Article 50, China AI-labeling Measures), and the 2024-2026 compliance calendar.
