deprecated: false
description: >-
Transform existing videos with new prompts using Wan's advanced AI model
## Overview
Transform existing videos by applying new text prompts using the Wan 2.6
Video to Video model. This allows you to modify or enhance videos with
different styles, actions, or themes while preserving the original video
structure.
## File Upload Requirements
Before using this API, you need to upload your video files:
### Step 1: Upload Video
Use the File Upload API to upload your source video.
- [File Upload API](/file-upload-api/quickstart) - Learn how to upload
videos and get file URLs
### Step 2: Get File URL
After upload, you'll receive a file URL that you can use in the
`video_urls` parameter.
:::warning[]
- Supported formats: MP4, QuickTime, Matroska
- Maximum file size: 10MB
- Maximum 3 video URLs per request
- Video content should be appropriate and follow usage guidelines
:::
## Usage Examples
:::tip[]
- Use descriptive prompts to specify how you want the video to change
- The model preserves the original video timing and structure
- Experiment with different prompt styles to achieve desired results
:::
## Query Task Status
After submitting a task, use the unified query endpoint to check
progress and retrieve results:
Learn how to query task status and retrieve generation results
::: tip[]
For production use, we recommend using the `callBackUrl` parameter to
receive automatic notifications when generation completes, rather than
polling the status endpoint.
