Wan

Alibaba’s Wan 3.0: 480p, 720p and 1080p, 2 to 30 seconds in every common shape, sound included, and up to 10 reference images in one shot.

Prices

Sound comes at no extra cost; set generate_audio to false for a silent clip. A video is charged only when it’s delivered.

What it takes

• A prompt of up to 8,000 characters. Wan has no negative prompt.
• A first_frame (and optionally a last_frame), or up to 10 reference_images, not both.
• Lengths from 2 to 30 seconds, in whole seconds.
• 16:9, 9:16, 1:1, 4:3, 3:4 and 21:9. From a first frame, the video takes the image’s shape unless you set aspect_ratio.
• A seed, to make a result you liked again with small changes.

Reference images

Give up to 10 images of people, products, places or a look, and mention them in the prompt by their order: Image 1, Image 2 and so on. @Image1, as the Playground writes it, works the same. Wan puts them together in one shot, so a character can hold a product or stand in a place you chose.

Prompting

• Describe the motion and the camera, not just the scene: “slow push in”, “static wide shot”, “drone shot rising over the bay”.
• Name the light and mood: “overcast morning”, “neon at night”, “golden hour backlight”.
• For speech, put the line in quotes and say who says it.
• There’s no negative prompt, so describe the look you want, such as “clean frame, sharp focus”, rather than what to avoid.

Good to know

• Most clips are ready in about 2 minutes; long 1080p clips take longer.
• Draft at 480p, then render the final cut at 720p or 1080p once the prompt is right.
• Prompts or images that may break the content rules can be declined (content_policy); declined videos are free.
• Videos are kept for 30 days; download the ones you want to keep.
