## Create Task
Use this endpoint to create a new reference-to-video generation task.
**Get Task Details**
After submission, use the unified query endpoint to check task progress and retrieve results
::: tip[]
For production use, we recommend providing the `callBackUrl` parameter
so your service can receive completion notifications instead of polling
for task status.

properties:
model:
type: string
enum:
- wan/2-7-r2v
default: wan/2-7-r2v
description: >-
The model name used for generation. This field is required.
This endpoint must use the `wan/2-7-r2v` model.
examples:
- wan/2-7-r2v
callBackUrl:
type: string
format: uri
description: >-
Callback URL for task completion notifications. Optional
parameter. If provided, the system will send a POST request
to this URL when the task completes, whether it succeeds or
fails. If omitted, no callback notification will be sent.
examples:
- https://your-domain.com/api/callback
input:
type: object
description: Input parameters for the reference-to-video task.
required:
- prompt
properties:
prompt:
type: string
maxLength: 5000
description: >-
Text prompt. Required. Describes the desired elements
and visual features in the generated video. Supports
Chinese and English. Maximum length: 5000 characters.
examples:
- >-
Image 1 is eating, while video 1 and image 2 are
singing beside it.
negative_prompt:
type: string
maxLength: 500
description: >-
Optional negative prompt describing what should not
appear in the video. Supports Chinese and English.
Maximum length: 500 characters.
examples:
- >-
low resolution, errors, worst quality, low quality,
malformed, extra fingers, bad proportions
reference_image:
type: array
maxItems: 5
items:
type: string
format: uri
description: >-
Array of reference image URLs. At least one of
`reference_image` or `reference_video` must be provided.
The total number of images and videos cannot exceed 5.
examples:
- - https://example.com/demo/ref-image-1.png
- https://example.com/demo/ref-image-2.png
reference_video:
type: array
maxItems: 5
items:
type: string
format: uri
description: >-
Array of reference video URLs. At least one of
`reference_image` or `reference_video` must be provided.
The total number of images and videos cannot exceed 5.
examples:
- - https://example.com/demo/ref-video-1.mp4
first_frame:
type: string
format: uri
description: >-
First frame image URL. At most one image can be
provided. If supplied, `aspect_ratio` is ignored and the
output uses a ratio close to the first frame image.
examples:
- https://example.com/demo/first-frame.png
reference_voice:
type: string
format: uri
description: >-
Audio URL used to specify the voice timbre of the
subject in the reference material.
Rules:
- If `reference_video` contains audio and
`reference_voice` is not provided, the original video
audio is used by default
- If both `reference_video` and `reference_voice` are
provided, `reference_voice` takes priority
Audio limits:
- Formats: `wav`, `mp3`
- Duration: `1` to `10` seconds
- File size: up to `15MB`
examples:
- https://example.com/demo/reference-voice.mp3
resolution:
type: string
enum:
- 720p
- 1080p
default: 1080p
description: >-
Output video resolution tier. Available values: `720p`,
`1080p`. Default value: `1080p`.
examples:
- 1080p
aspect_ratio:
type: string
enum:
- '16:9'
- '9:16'
- '1:1'
- '4:3'
- '3:4'
default: '16:9'
description: >-
Output video aspect ratio.
Effective logic:
- If `first_frame` is not provided: the video is
generated using the specified `aspect_ratio`
- If `first_frame` is provided: `aspect_ratio` is
ignored and the output uses a ratio close to the first
frame image
examples:
- '16:9'
duration:
type: integer
minimum: 2
maximum: 10
default: 5
description: >-
Output video duration in seconds. Valid range is an
integer from `2` to `10`. Default value: `5`.
examples:
- 5
prompt_extend:
type: boolean
default: true
description: >-
Whether to enable prompt rewriting. When enabled, the
model expands the input prompt. This usually works
better for short prompts but increases processing time.
examples:
- true
watermark:
type: boolean
default: false
description: >-
Whether to add a watermark. The watermark is placed in
the lower-right corner of the video with the fixed text
"AI generated".
examples:
- false
seed:
type: integer
minimum: 0
maximum: 2147483647
description: >-
Random seed. Range: `0-2147483647`. If omitted, the
system generates one automatically.
examples:
- 0
nsfw_checker:
type: boolean
description: >-
Defaults to false. You can set it to false based on your
needs. If set to false, our content filtering will be
disabled, and all results will be returned directly by
the model itself.
