Notes

Turns a single portrait image into a talking avatar video, driven either by an audio file you supply or by text spoken with a built-in voice.

Inputs

  • image: the portrait to animate. Use a clear, front-facing subject.
  • audio: the speech to perform, or lip_sync_tts_content with lip_sync_tts_speaker_id to have the model speak your text. Fourteen named voices are available plus Auto.
  • prompt is optional and can describe delivery or framing.

Output

  • 360p, 540p, 720p and 1080p.

Billing

  • Billed per second of speech at the rate for the output resolution. Text-to-speech input is metered in 15-character blocks at the same rate, so the charge tracks the length of the script.

Input limits

  • Image: PNG, JPEG or WebP, up to 20MB and 10000px on the long edge.
  • Audio: MP3, WAV, M4A or AAC.
