常见问题FAQ
Q: 适合个人创作者吗？Q: Good for solo creators?
偶尔使用性价比一般；如果你要持续产出多语种讲解视频，则非常划算。Marginal for occasional use; excellent if you consistently produce multilingual explainers.
Q: 数字人形象有版权风险吗？Q: Any rights issues with avatars?
使用平台提供的官方数字人一般没问题；不要克隆真人明星形象，避免法律风险。Platform-provided avatars are fine. Don't clone real celebrities — that creates legal risk.
Q: 能替代真人出镜吗？Q: Can it replace a real presenter?
在培训、说明类内容中完全可以；但需要建立信任的场合（如创始人 IP）真人更有优势。For training and explainers, yes. For trust-building moments (founder-led), a real person is stronger.
