Capability examples

Describe the subject, action, setting, visual style, and camera motion in prompt. Use wan2.2-t2v-a14b; do not send an image.A useful prompt states the primary motion before secondary visual details:

A paper lantern floats above a quiet riverside town at dusk. The camera follows from below as warm reflections ripple across the water.

Use wan2.2-i2v-a14b and provide one public image URL in image. The image defines the first frame; prompt describes how the scene should move.

The image above is an Alibaba Cloud upstream input example. It was not reproduced through AnyFast.
