High-fidelity talking avatar video generation from a portrait with script or audio control

One of Auray's catalogue models: the same key, the same credits, the same job lifecycle as every other address.

Its request shape is published below. Whether it runs right now is GET /v1/catalogue's word, with no key needed: its addresses say connected for an address that runs, and a submit to any other is refused before anything is charged — described answers 501 model_not_connected, paused 503 model_disabled.

Category text-to-video · Scope video:write (or external:write on an older key) · Price Credits per character of text (counted as spoken:speech.text): 0.1864 for resolution=720p, settings.voicePrompt="Say the following."; 0.3354 for resolution=1080p, settings.voicePrompt="Say the following.". Each character of speech.text counts the time it takes to say: 1.1672 a letter of the Latin or Cyrillic script, a space or a pause mark; 1.7679 an Arabic or Hebrew letter; 3.4818 a kana; 4.8746 a Hangul syllable, a Greek letter or a letter of any other script; 24.3726 a Han character, seven kana; 16 a letter read by its name (alone, in a word with no vowel, or in a word in capitals of four letters or fewer or that no word could be said as, its plural or possessive s a letter); 20 a digit; 48 a symbol or an emoji; a combining mark none. Each band has its own least and most a request is counted at. A settings.voicePrompt other than its default, "Say the following.", is refused before any charge: no published bound limits how long a delivery instruction makes a text run. A request that sends inputs.audio is refused before any charge: it has no price on this model. Quoted when you submit, at the most the request can cost; the charge settles to what the job cost and never above the quote. The submit's answer carries the quote as credits_quoted, and credits_charged says what has been taken.

#Input

FieldTypeRequiredDefaultDescription
inputsobjectyes—
inputs.frameImagesstring[]yes—Images that pin frames of the video, as a list of image URLs: one image is the first frame, two are the first and the last, and three or more anchor the first and the last with the rest spread evenly between. Each item is a plain URL; the object form that names a frame or a timestamp is not accepted here. Documented range: 1 to 1.
inputs.audiostringno—Audio input (an http(s) URL; upload a local file first and send its read URL). A URL.
positivePromptstringno—Text prompt describing elements to include in the generated output.
resolutionstringno"720p"Resolution preset for the output. When used with input media, automatically matches the aspect ratio from the input. One of "720p", "1080p".
seedintegerno—Random seed for reproducible generation. When not provided, a random seed is generated in the unsigned 32-bit range. Documented range: 0 to 2,147,483,647.
speechobjectno—
speech.textstringno—Text to convert to speech. Documented range: 1 to 5,000 characters.
speech.voicestringno"Zephyr (Female)"Voice identifier to use for speech generation. One of "Zephyr (Female)", "Puck (Male)", "Charon (Male)", "Kore (Female)", "Fenrir (Male)", "Leda (Female)", "Orus (Male)", "Aoede (Female)", "Callirrhoe (Female)", "Autonoe (Female)", "Enceladus (Male)", "Iapetus (Male)", "Umbriel (Male)", "Algenib (Male)", "Despina (Female)", "Erinome (Female)", "Laomedeia (Female)", "Achernar (Female)", "Algieba (Male)", "Schedar (Male)", "Gacrux (Female)", "Pulcherrima (Female)", "Achird (Male)", "Zubenelgenubi (Male)", "Vindemiatrix (Female)", "Sadachbia (Male)", "Sadaltager (Male)", "Sulafat (Female)", "Alnilam (Male)", "Rasalgethi (Male)".
speech.languagestringno"en-US"Language code for speech generation. Documented range: 1 or more. One of "en", "en-US", "en-GB", "es", "es-ES", "fr", "fr-FR", "de", "de-DE", "it", "it-IT", "pt-BR", "ja", "ja-JP", "ko", "ko-KR", "hi", "hi-IN".
settingsobjectno—
settings.promptUpsamplingbooleannofalseAutomatically enhance the prompt for improved results.
settings.safetyFilterbooleannotrueContent safety filtering on prompts and input image. Always on: a false is sent as true.
settings.voicePromptstringno"Say the following."Speaking style, tone, pacing, or emotion instructions for delivery.
outputTypestringno"URL"Video output type. One of "URL".
outputFormatstringno"MP4"Specifies the file format of the generated output. The available values depend on the task type and the specific model's capabilities. - `JPG`: Best for photorealistic images with smaller file sizes (no transparency). - `PNG`: Lossless compression, supports high quality and transparency (alpha channel). - `WEBP`: Modern format providing superior compression and transparency support. - `MP4`: Widely supported video container (H.264), recommended for general use. - `WEBM`: Optimized for web delivery. - `MOV`: QuickTime format, common in professional workflows (Apple ecosystem). - `GIF`: Animated image format (no audio), suitable for short loops or previews. - `MP3`: Compressed audio, smaller file size. - `WAV`: Uncompressed, high-quality audio. - `FLAC`: Lossless compression. - `OGG`: Open-source compressed audio format (Vorbis codec). - `SVG`: Scalable Vector Graphics. - `TIFF`: High-quality output supporting layers. - `GLB`: Binary glTF format for 3D models, including geometry, textures, and PBR materials. > [!NOTE] > **Transparency**: If you are using features like background removal or LayerDiffuse that require transparency, you must select a format that supports an alpha channel (e.g., `PNG`, `WEBP`, `TIFF`). `JPG` does not support transparency. One of "MP4", "WEBM", "MOV".
outputQualityintegerno95Compression quality of the output. Higher values preserve quality but increase file size. Documented range: 20 to 99.
safetyobjectno—
safety.checkContentbooleanno—Enable or disable content safety checking. Increases total generation time. Always on: a false is sent as true.
safety.modestringno"fast"Safety checking mode for video generation. Only fast or full is sent here: any other value is sent as fast. One of "fast", "full".
idempotency_keystringno—Your own name for this request. Send the same one twice and the second call is answered with the first request rather than charged again. Idempotency-Key: as a header is accepted as an alias — that is the spelling a retrying proxy replays, and the one to use when running a model on auray.run, where a request that outlives its connection is answered 504 and recovered by replay. Omit it and the platform mints one. 1 to 64 characters.

#Rules

Across fields, as the model's documentation states them. Each is judged before anything is charged — warned with a Deprecation header until enforcement starts — and listed as JSON Schema under x-auray-rules in the openapi.json.

  • When resolution is sent, inputs.frameImages is required.
  • Send exactly one of inputs.audio or speech.text.

#Example

curl -X POST https://queue.auray.run/auray-serverless/prunaai/p-video-avatar \
  -H "Authorization: Bearer $AURAY_API_KEY" \
  -H "content-type: application/json" \
  -d '{
  "inputs": {
    "frameImages": [
      "https://v3b.auray.media/examples/samples/still-life.jpg"
    ]
  },
  "speech": {
    "text": "a brass orrery on a walnut desk, morning light from a window to the left"
  }
}'

The same body on https://auray.run runs synchronously and answers the result — unless it usually takes longer than a run may hold its connection, which is refused 400 model_not_synchronous before anything is charged. Options — ?webhook=, ?wait=, priority and timeout headers — are on Submit a request.
