This is a fine-tuned model by MuleRouter based on the Wan2.6 Image-to-Video architecture. It offers improved quality and performance for specific use cases.

Overview

Generate videos from images using the wan2.6-i2v-spark model with support for longer durations, multi-shot generation, and optional last frame specification.

Key Features

Image-to-video generation with audio support
1080P resolution
5s, 10s, or 15s duration
Single or multi-shot generation
Optional first and last frame specification
Fine-tuned for enhanced visual quality

Image Requirements

Property	Requirement
Formats	JPEG, JPG, PNG (no transparency), BMP, WEBP
Dimensions	[360, 2000] pixels for both width and height
File Size	Max 10MB
Input	Public URL or Base64 encoded data

Example Requests

Basic Image-to-Video

{
  "prompt": "A black cat looks curiously at the sky, camera gradually rises from eye-level to overhead",
  "image": "https://example.com/first_frame.jpg",
  "resolution": "1080P",
  "duration": 5
}

With Last Frame (Interpolation)

{
  "prompt": "Character starts walking, expression changes naturally",
  "image": "https://example.com/person.jpg",
  "last_frame": "https://example.com/person_end.jpg",
  "resolution": "1080P",
  "duration": 10,
  "audio": true
}

Multi-shot Video

{
  "prompt": "Scene transition with smooth camera movement",
  "image": "https://example.com/scene.jpg",
  "resolution": "1080P",
  "duration": 15,
  "prompt_extend": true,
  "multi_shots": "multi"
}

Parameters

last_frame

Optional: Yes
Description: End frame image for video interpolation between first and last frame
Use case: Create smooth transitions between two specific frames

multi_shots

Default: single
Effect: When prompt rewriting is enabled, controls whether the output is single-shot or multi-shot
Only effective when: prompt_extend is enabled

Authorizations

Authorization

string

header

required

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.

Body

application/json

prompt

string

required

Motion/story description for the video (max 2000 characters).

Maximum string length: 2000

image

string

required

First-frame image (URL or Base64). Supported formats: JPEG/JPG/PNG/BMP/WEBP, 360-2000px, ≤10MB.

negative_prompt

string

Negative prompt describing unwanted content (max 500 characters).

Maximum string length: 500

resolution

enum<string>

default:1080P

Output resolution tier:

Available options:

1080P

duration

enum<integer>

Video duration in seconds. Supported values 5, 10, or 15.

Available options:

5,

10,

15

prompt_extend

boolean

default:true

Enable intelligent prompt rewriting (slightly longer latency, better detail).

shot_type

enum<string> | null

default:single

Specifies the shot type for video generation.

Only takes effect when prompt_extend is enabled.

multi: Outputs multi-shot video

Available options:

single,

multi

audio

boolean | null

default:true

Enable automatic audio generation. Set to false to force a silent output.

audio_url

string<uri> | null

Custom audio file URL (wav/mp3, 3-30s, ≤15MB). Overrides the audio flag.

seed

integer

Random seed [0, 2147483647].

Required range: 0 <= x <= 2147483647

safety_filter

boolean | null

default:true

Enable content safety filter. Defaults to true. Set to false to disable content safety inspection.
