Wan 3.0 Review: AI Video With Sound, Up to 30 Seconds

Wan 3.0 is the new generation of Alibaba's Wan video models. It produces clips with sound built in, has a "thinking" mode for prompts, animates photos and lets you set any duration from 3 to 30 seconds in one-second steps. In this Wan 3.0 review we cover how to use the model online in WebTerra AI, what a generation costs, how to write prompts that include sound and how the new version stacks up against its neighbours in the catalogue.

The Wan family is known for being open and affordable; earlier versions won fans with a strong balance of quality and price. Wan 3.0 takes a clear step forward: it is no longer just a silent picture generator but a model that delivers a finished clip with an audio track. For social media and fast-turnaround content, that means fewer steps, with no separate hunt for sound effects or ambience.

Another key difference is flexible duration. Most video models offer two or three fixed lengths; here you can pick any length from 3 to 30 seconds. Wan 3.0 is available in the video generation section of WebTerra AI.

What Wan 3.0 can do

• Sound built in. By default the model generates the clip together with an audio track.
• Thinking mode. The model works through the prompt before generating, which helps with complex scene descriptions.
• Text-to-video. A clip from scratch based on your description.
• Photo animation. An uploaded image becomes the basis of the video.
• First and last frame. Set how the scene starts and ends.
• 3–30 seconds. Any whole number of seconds in that range.
• Three resolutions. 480p, 720p and 1080p.
• Five aspect ratios. 16:9, 9:16, 1:1, 4:3 and 3:4.

The dashboard presets cover typical jobs: a cinematic shot, a product video for a marketplace or social media, nature and time-lapse, photo animation, a character line with sound, a scene with ambient sound, a vertical social video for Reels, a first-person vlog, a food close-up and a fantasy scene. Two of those presets are built specifically around audio, which is a hint that with Wan 3.0 you should describe not only what viewers see but also what they hear.

The model's demo clip shows a paper boat floating down a rainy street gutter with streetlights reflected in the water. It is a small scene, but it shows nicely how the model handles fine water physics, light and atmosphere.

Wan 3.0 pricing

The catalogue's reference price is for a 3-second clip at 720p. Here is what that costs on each plan:

Cost depends on duration and resolution. The base rates are roughly 8.3 credits per second at 480p, 17 at 720p and 34 at 1080p. Pro and Ultra plans apply a discount, so the actual charge is a little lower.

Good news: the 60 free credits cover a 3-second clip at 720p or a 5-second clip at 480p. That is enough to judge the sound and motion quality before buying a plan. Details are on the WebTerra AI pricing page.

Prompt examples

Because Wan 3.0 generates audio, describe what can be heard as well as what can be seen. Ending with "no text, no captions, no watermark" keeps stray lettering out of the frame.

1. The model's demo prompt. A paper boat in the rain.

A paper boat floating down a rainy street gutter, raindrops hitting the water, reflections of streetlights, shallow depth of field, no text, no captions, no watermark

2. Scene with ambient sound. Sound described together with the visuals.

A cozy mountain cabin at night during a snowstorm, fire crackling in the fireplace, wind howling outside, warm orange light, slow push-in, no text, no watermark

3. Character line. A character says a short phrase.

Close-up of a young barista behind a cafe counter, smiling at the camera and saying "Your coffee is ready", espresso machine hissing in the background, natural light, no captions, no watermark

4. Vertical video for Reels. A punchy 9:16 clip.

Vertical video, a skateboarder doing a kickflip in an urban skatepark at sunset, wheels rolling on concrete, crowd cheering, energetic handheld camera, no text, no watermark

5. Product video. An ad for a marketplace.

Wireless headphones slowly rotating on a white pedestal, soft studio light, subtle electronic hum, clean premium look, no text, no watermark

6. First-person vlog. A POV shot that looks filmed on a phone.

POV smartphone footage walking through a busy night market, sizzling street food, vendors calling out, colorful lanterns overhead, slight camera shake, no text, no watermark

Tips for prompting Wan 3.0

Describe the sound in its own sentence

Audio is generated alongside the video, so give the model a cue: what is heard up front and what sits in the background. "Fire crackling, wind howling outside" works better than hoping the model will guess.

Put dialogue in quotes

If a character needs to say something, quote the line word for word and keep it short. Long monologues are hard to fit into a short clip.

Make the most of flexible duration

You do not have to squeeze your idea into 5 or 10 seconds. A story loop needs 3–4 seconds, an atmospheric intro 8–12, a fuller scene up to 30. Matching duration to the job means you do not pay for seconds you will cut anyway.

Let thinking mode handle complexity

The thinking mode helps when a description includes several events, characters or conditions. Clear structure still helps: setting first, then action, then camera and sound.

Draft at 480p

Work out composition and motion at the lowest resolution and switch to 1080p for the final version. On long clips, the cost difference is substantial.

Use cases

• Social media managers and creators. Finished vertical clips with sound for Reels and Shorts.
• Marketplaces and e-commerce. Product videos without a separate sound pass.
• Advertising. Short spots with character lines.
• Travel and food content. POV shots with the atmosphere of streets and kitchens.
• Storytelling. Fuller scenes up to 30 seconds without stitching several generations.
• Budget-conscious creators. Testing ideas at 480p for minimal cost.

Workflow: a Reel with sound in one pass

Choose 9:16 and 6–8 seconds, which is enough for one strong moment that holds attention. Describe the action, the camera move and the sound: city noise, music from a street cafe, footsteps. Generate a 480p draft first to check that motion and audio work, then run the final at 720p or 1080p. The finished clip can go straight out without a separate sound pass.

Workflow: an animated product photo

Upload a studio product photo as the first frame and ask for a slow rotation or push-in with light background sound. If the clip should end on a specific composition, such as the product in front of its packaging, set that as the last frame. You get a short ad for a product listing or Stories without a shoot.

Wan 3.0 compared with other video models

If budget comes first and you do not need sound, the previous version, Wan 2.7, remains an affordable option. For 4K with sound, look at Veo 3.1. Kling 2.6 Pro is an alternative for clips with audio, and when you need several scenes in one video, try Seedance 2.0. Wan 3.0 stands out with flexible duration up to 30 seconds and the combination of sound with a thinking mode.

The catalogue has other video models too. Kling 3.0 is known for motion quality and suits complex human movement, while Hailuo 02 is a fast option for animating photos. If you need a clip longer than 10 seconds in a single generation, with sound, Wan 3.0 is a convenient, practical choice.

Limitations and what to keep in mind

• 1080p maximum. For 4K you need a different model or an upscale.
• Long clips cost more. 30 seconds at 1080p costs ten times as much as 3 seconds at the same quality.
• No 21:9. Available ratios are 16:9, 9:16, 1:1, 4:3 and 3:4.
• Sound is automatic. Precise sound design or music may still need work in the edit.
• Keep lines short. Split longer dialogue across several clips.
