    "image": "https://assets-public.namifusion.com/uploads/images/2026-03-04/8dc7b384cdb9.png",
    "prompt": "Transform a static image of a sunset over the ocean into a dynamic and vibrant AI-generated video.",

What parameters does it take?

image (Image): required

negative_prompt (Negative Prompt): optional

resolution (Resolution): optional, default "1080P"

duration (Duration): optional, default 5

prompt_extend (Enable Prompt Expansion): optional, default false

How do you write prompts for Alibaba WAN 2.2?

1. Subject first: lead with the actor and action, then add environment, lighting and style ("an astronaut sprinting through a neon street in the rain, cinematic, shallow depth of field").

2. Concrete nouns beat stacked adjectives: "85mm portrait lens, golden-hour backlight" works far better than "very beautiful, ultra high quality".

3. Change one variable per iteration: pin the seed to reproduce a result, tweak a single phrase at a time so you know what actually moved the output.

4. State negatives positively: instead of "no blur", ask for "sharp focus, crisp details".

How much does it cost?

Pay-per-use in credits. A typical run costs about $0.800 ($1 = 100 credits); the exact price varies with parameters like resolution or duration, and the playground shows the exact quote before you submit.
