Google Veo 3.1 — Reference-to-Video Model

Veo 3.1 Reference-to-Video brings static images to life by combining visual reference consistency with cinematic motion generation. Powered by Google DeepMind’s next-generation Veo 3.1 architecture, this model transforms up to three reference images into coherent 5-second videos with smooth motion, accurate visual alignment, and synchronized native audio.

🌟 Key Features

🧠 Multi-Image Reference Support

  • Accepts up to three reference images to define the subject, environment, or style.
  • Maintains consistent identity, lighting, and appearance across frames.
  • Ideal for animating people, objects, or scenes with reliable fidelity.

🎬 Cinematic Video Generation

  • Produces 5-second motion clips at 1080p or 720p resolution.
  • Adds camera dynamics such as panning, zooming, or subtle perspective drift.
  • Supports synchronized audio generation, matching dialogue or ambient context.

💡 Smart Prompt Adherence

  • Interprets both text instructions and visual cues for precise motion storytelling.
  • Automatically harmonizes character interactions, props, and backgrounds.

⚙️ Capabilities

  • Input:

  • Up to 3 reference images (JPEG / PNG / WEBP)

  • Text prompt describing motion, action, and scene context

  • Output:

  • Choose resolution (720p, 1080p, or 4K).

  • Optional synchronized audio

  • Negative Prompt (optional):

  • Exclude unwanted artifacts or elements (e.g., “no text”, “no flicker”).

  • Seed (optional):

  • Reproduce specific results for consistent creative control.

Pricing

Each request generates an 8-second video. Pricing depends on the resolution and whether audio generation is enabled.

ResolutionDurationWithout AudioWith Audio
720p8s$1.60$3.20
1080p8s$1.60$3.20
4K8s$3.20$4.80

Billing Rules

  • Video duration is fixed at 8 seconds.
  • generate_audio=true uses the With Audio price.
  • generate_audio=false uses the Without Audio price.
  • Default configuration: 1080p, audio enabled — $3.20.
  • Providing additional reference images, up to the supported maximum of 3, does not add a separate charge.
  • negative_prompt and seed do not add separate charges.

🧩 How to Use

  1. Upload up to 3 reference images — define the subject, object, or visual style.
  2. Write a text prompt — describe the action, setting, and camera motion.
  3. (Optional) Add a negative prompt to remove unwanted details.
  4. Choose resolution (720p or 1080p).
  5. (Optional) Enable audio generation for synchronized sound.
  6. Click Run to generate your 8-second cinematic video.

💡 Best Practices

  • Use clear, well-lit reference images with similar styles and proportions.
  • Keep prompts concise but specific (e.g., “The man in image 1 waves to the penguins in image 2 under bright sunlight”).
  • Avoid overly complex scenarios with many characters or fast movement.
  • Enable audio for more immersive storytelling results.

📝 Notes

  • Ensure uploaded images are valid and accessible URLs or uploaded locally.
  • If the output looks unstable, reduce reference count or simplify the prompt.
  • Follow Google’s content safety rules; modify the prompt if flagged.
  • For best performance, prefer portrait-oriented subjects and balanced lighting.

Veo3.1 Reference To Video API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/google/veo3.1/reference-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 Veo3.1 Reference To Video below.

Veo3.1 Reference To Video API — Frequently asked questions

What is the Veo3.1 Reference To Video API?

Veo3.1 Reference To Video is a Google model for reference-guided video generation, exposed as a REST API on WaveSpeedAI. Google Veo3.1 Reference-to-Video performs image-to-video generation that preserves a specific subject's appearance and identity from provided reference images, enabling consistent character or product motion across frames. 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 Veo3.1 Reference 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 Python, JavaScript, and cURL examples for submitting requests and polling results. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/google/google-veo3.1-reference-to-video.

How much does Veo3.1 Reference To Video cost per run?

Veo3.1 Reference To Video starts at $3.2 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 Veo3.1 Reference To Video accept?

Key inputs: `prompt`, `images`, `resolution`, `seed`, `negative_prompt`, `generate_audio`. 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/google/google-veo3.1-reference-to-video.

How long does Veo3.1 Reference To Video take to generate?

Reported generation time on WaveSpeedAI is around 60 seconds per request. This is an estimate, not a latency guarantee; queue time and input settings can change the total wait. live status is visible in the prediction record.

Can I use Veo3.1 Reference To Video outputs commercially?

Commercial usage rights depend on the model's license, set by its provider (Google). Check the provider's applicable terms and WaveSpeedAI's Terms of Service before commercial use.
