Wan2.2 官方建议在文生视频前先扩写提示词，用更完整的主体、动作、镜头和环境描述减少歧义。保留用户原意，把扩写当成可审查的中间步骤，而不是黑盒改写。 Wan2.2 recommends extending a text-to-video prompt with subject, action, camera, and environment details before rendering. Keep the user's intent visible and treat the extension as a reviewable intermediate step, not a black box.
