Are your AI UGC ads still “obviously fake”—wandering eyes, laggy lip-sync, broken hand movements—and quietly burning your ad budget? This post reveals a practical, industry-style SOP: how to separate Person / Motion / Voice and combine them into three realism-tested workflows (Nano Banana Pro × KlingAI × Minimax / Veo 3.1 / Sora 2) to create UGC that looks far more human. You’ll get copy-paste prompts and scripts, plus a 15-second 3-cut editing formula that builds authentic pacing. Finish with the “3-gate” pre-publish checklist (eyes / lips / hands) so you only launch creatives that are ready to perform.
