InfiniteTalk Video-to-Video

What is InfiniteTalk?

InfiniteTalk creates new videos by combining an input silent video and an audio track. It ensures precise lip synchronization while aligning head, face, and body movements with the audio. With optional masking and prompting, you can control which areas move and how the scene appears. The model also maintains visual identity for natural and consistent results.

Why it looks great

  • Accurate lip synchronization: matches lip motion precisely to the audio.
  • Full-body coherence: aligns head pose, facial expressions, and posture with speech.
  • Mask control: optional mask images let you define which regions can move.
  • Instruction following: prompts can guide style, pose, or behavior.
  • Identity preservation: ensures consistent visual identity across all frames.

Pricing

Output ResolutionCost per 5 secondsMax Length
480p$0.1510 minutes
720p$0.3010 minutes

Billing Rules

  • Standard Rate: $0.03 per second
  • HD (720p) Rate: $0.06 per second (Double the Standard Rate)
  • Minimum Charge: All videos are billed for a minimum of 5 seconds (costing at least $0.15).
  • Billing Cap: To keep your costs predictable, billing is capped at 600 seconds (10 minutes).

How to Use

  1. Upload the audio file.
  2. Upload a video as the base.
  3. (Optional) Upload a mask image to control which regions can move.
  4. (Optional) Write a prompt to guide the style, pose, or expressions.
  5. Select the output resolution (480p or 720p).
  6. Set the seed if you want reproducibility.
  7. Submit the job and download the generated video.

Note

  • Max clip length per job: 10 minutes
  • Processing speed: ~10–30 seconds of wall time per 1 second of video (varies by resolution and queue load)
  • Mask safety tip: Do not upload the full image as mask_image. The mask should only cover the regions you want to animate—otherwise the result may render as fully black.

Infinitetalk Video To Video API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/wavespeed-ai/infinitetalk/video-to-video with your input as JSON. The endpoint returns a prediction id. Start polling the result endpoint around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. On completed, read output values from data.outputs. Examples for Infinitetalk Video To Video below.

Infinitetalk Video To Video API — Frequently asked questions

What is the Infinitetalk Video To Video API?

Infinitetalk Video To Video is a WaveSpeedAI model for talking-avatar generation, exposed as a REST API on WaveSpeedAI. Audio-driven InfiniteTalk turns one video plus audio into realistic talking or singing videos with lip-sync in 480p or 720p. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing. You can call it programmatically or try it from the playground above.

How do I call the Infinitetalk Video To Video API?

POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header. Submission returns a prediction ID. Poll the result endpoint starting around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. The playground generates production-oriented Python, JavaScript, and cURL examples with timeouts, transient-error handling, and safe GET retries. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/wavespeed-ai/infinitetalk-video-to-video.

How much does Infinitetalk Video To Video cost per run?

Infinitetalk Video To Video starts at $0.15 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.

What inputs does Infinitetalk Video To Video accept?

Key inputs: `prompt`, `video`, `audio`, `resolution`, `seed`, `mask_image`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/wavespeed-ai/infinitetalk-video-to-video.

How long does Infinitetalk Video To Video take to generate?

Average end-to-end generation time on WaveSpeedAI is around 116 seconds per request — measured across recent runs. Queue time scales with global demand; live status is visible in the prediction record.

Can I use Infinitetalk Video To Video outputs commercially?

Commercial usage rights depend on the model's license, set by its provider (WaveSpeedAI). The license summary appears on the model card above; see WaveSpeedAI's Terms of Service for platform-level conditions.
