API Endpoint

POSThttps://api.segmind.com/v1/infinite-talk

Parameters

audiorequired
string (uri)

URL of the audio file to synchronize with the animation. Use clear speech recordings; start with 5–15 second clips for faster iteration and testing.

imagerequired
string (uri)

URL of the source image or video to animate with audio-driven full-body motion. Use high-resolution, well-lit images for better identity and background preservation.

promptrequired
string

Describe the scene, emotion, or action guiding the full-body animation. Try specific phrases like 'A speaker gestures confidently while presenting to an audience.'

Default: "A professional woman speaks confidently, gesturing naturally while addressing the camera."
base64optional
boolean

Encodes the output video as a Base64 string instead of a file URL. Keep false for standard URL-based delivery; set true only if your integration requires raw encoded output.

Default: false
fpsoptional
integer

Frames per second for the output video. Use 16–20 for fast test renders; set 25–30 for smooth, production-quality animations.

Default: 25Range: 16 - 30
resolutionoptional
string

Sets the output video resolution. Use 480p for quick drafts and iteration; choose 720p for final high-quality renders and presentations.

Default: "480p"
Allowed values :
"480p""576p""720p"
seedoptional
integer

Controls output randomness for reproducible results. Fix the seed for consistent animations; vary it to explore different motion styles from the same inputs.

Default: 42424242

Response Type

Returns: Video

Asynchronous requests (v2)

Use Async for video, long-running (>~60s), or high-concurrency workloads; Sync is simplest for fast image & LLM calls. Async submits a request and you poll it to completion.

  1. 1
    POST /v2/infinite-talk

    Submitreturns request_id, status_url, response_url

  2. 2

Status states

QUEUEDAccepted, waiting for a worker
PROCESSINGRunning on a worker
COMPLETEDDone — result body is ready
FAILEDErrored (incl. content/RAI blocks)
  • A FAILED request is served as HTTP 422 — the body still carries the error detail.
  • An unknown or expired request_id returns HTTP 404.
  • Results are retained for 1 hour, then expire.
  • Content / RAI blocks surface as FAILED, not a separate state.
  • Track completion by polling the status endpoint.
