}**[Core Function]** SkyReels Single-Actor Avatar (audio-to-video) drives a talking-avatar video from a single portrait image and one audio track. **[Strengths]** Lip-synced single-speaker talking-head video generated from an image plus audio. **[Best For]** Virtual presenters, single-speaker dubbing, and talking avatars. **[Limitations]** Do NOT use this for multi-speaker scenes (use the multi-actor flow) or when you only have text. It requires first_frame_image and exactly one audio segment (<=200s). mode=std outputs 720p, mode=pro outputs 1080p. **[Routing]** Provide a portrait first_frame_image and one audio URL in audios; choose mode=pro for 1080p output.
