# Vidu Image-to-Video

## Overview

Use the image to video endpoint with a supported model. Use the returned Task ID to retrieve its state, or provide callback_url for the deliveries documented below.

### Quick start

1. Create an API key and set it as RUNAPI_API_KEY.
2. Choose a supported model and send a POST request whose body matches that model's schema.
3. Store the returned task ID, then poll until a terminal state or handle the callbacks documented below.

## Endpoint

POST /api/v1/vidu/image_to_video

Base URL: https://runapi.ai

API version: v1

Authentication: Authorization: Bearer YOUR_API_TOKEN

## Supported models

Open a model page for current pricing, rate limits, and commercial-usage details.

- [vidu-q4-image-to-video](https://runapi.ai/models/vidu/q4-image-to-video)

## Request schema

Fields and allowed values depend on the selected model. When supplied, callback_url receives the Task deliveries documented below.
