Wan 3.0 vs Seedance 2.5: Tested for 30-Second Ads

Wan 3.0 is the cheaper way to get a 30-second AI video with sound in one generation: on BuzzVideo it costs 20 credits per second at 720p, against about 46 for Seedance 2.5 and about 31 for Kling 4.0. Seedance 2.5 is the stronger pick when you need many references in one clip (up to 30 images, 10 videos and 10 audio clips), while Wan 3.0 takes up to 10 images, 5 videos and 5 audio clips. For product demos and explainers with one product and one presenter, Wan 3.0 does the job for well under half the price.

Both models are in BuzzVideo AI's Marketing Agent; Wan 3.0 is available from the Starter plan up. Below: a spec and price table, the timed prompt we used, three Wan 3.0 videos (a 5-second test, a 15-second creator ad and a 30-second film) and what went wrong.

What is Wan 3.0?

Wan 3.0 is Alibaba's video generation model. Alibaba announced it in August 2026 as the successor to Wan2.7-Video, doubling the maximum clip length from 15 to 30 seconds. According to Alibaba's announcement and its Model Studio guide:

• One generation runs from 2 to 30 seconds, at 480p, 720p or 1080p and 30 fps.
• Dialogue, background music and sound effects are generated with the picture, and audio can be switched off.
• A generation can take up to 10 reference images, 5 reference videos and 5 reference audio clips (videos and audio up to 15 seconds in total each). Prompts address them by number, such as Image 1 or Video 1.
• Prompts can be written as a storyboard with timestamped shots; Alibaba's guide suggests 4–6 seconds per shot.
• Alibaba's API can also build a video from a document (PDF, PowerPoint, Word, Excel) or a public web page; on fal's Wan 3.0 reference-to-video endpoint that requires thinking mode.

BuzzVideo exposes the length, resolution, aspect ratio, sound and reference settings. Document and web-page inputs, and the faster Wan 3.0 Prime variant, are not part of BuzzVideo's Wan 3.0 settings today, so plan your ads around a written prompt plus reference images.

Wan 3.0 vs Seedance 2.5 vs Kling 4.0: specs and price

Specs and credits are from BuzzVideo's live model settings and pricing data on November 10, 2026. Seedance 2.5 prices are for generations without a reference video. Wan 3.0 and Seedance 2.5 both let you switch sound off.

The short version: Wan 3.0 is the budget option for long clips. A 30-second draft at 480p costs 300 credits, against 617 for Seedance 2.5 at 480p. Seedance 2.5 accepts three times as many reference images, which matters when one ad has to lock a product, a presenter, a location and a style frame at once. Kling 4.0 sits in between on price; see our Kling 4.0 guide.

How do you prompt Wan 3.0?

All three videos below used the same six-part structure. Alibaba's guide recommends timestamped shots, and the clearer the beats, the less the model improvises.

1. Format line. Length, orientation and style: "Create a 15-second vertical 9:16 UGC creator ad filmed on a phone."
2. Product lock. "Image 1 is the exact product", then the shape, colours, materials and label text, and "There is only one candle jar in the whole video."
3. Presenter and setting. One sentence each, and ask Wan to keep the face, hair and outfit the same throughout.
4. Timed beats. One block per time range with the shot, the action and the exact line in quotes. Write "hard cut" where you want a cut.
5. Sound. Name the voice, room tone and one or two product sounds, and say what to leave out.
6. Negative list. No captions, prices, watermarks, extra logos or morphing. Add text and offers later in the edit.

Copy-paste template

“Create a [LENGTH]-second [9:16 vertical / 16:9] [UGC creator ad / lifestyle product film] for [PRODUCT]. Image 1 is the exact product: [SHAPE, COLOURS, MATERIALS, LABEL TEXT]. Keep it identical to Image 1 in every shot. There is only one [PRODUCT] in the whole video. Do not invent other logos, text or packaging.

Setting: [ROOM, SEASON, LIGHT]. Presenter: [AGE, HAIR, OUTFIT, ACCENT]. Keep her face, hair and outfit the same in every shot.

0–4 seconds — [SHOT]. [ACTION]. She says: "[LINE 1]"
4–8 seconds — hard cut to [SHOT]. [ACTION]. "[LINE 2]"
8–11 seconds — hard cut to [SHOT]. [ACTION]. "[LINE 3]"
11–15 seconds — hard cut to [CLOSING SHOT]. "[LINE 4]"

Keep all dialogue verbatim and in this exact order.
Sound: her clear voice, [ROOM TONE], [1–2 PRODUCT SOUNDS]. No music, no narrator.
No captions, subtitles, prices, watermarks or extra logos. Normal hands with five fingers. The product stays rigid and never morphs.”

- Wan 3.0 ad prompt template

Tested: three Wan 3.0 videos for one fictional product

We made a product photo of FIRLIGHT, a fictional balsam-and-cedar candle in an amber glass jar with an oak lid, using GPT Image 2.5 Sunburst (11 credits). That single image was the only reference in every Wan 3.0 generation below.

Step 1: a 5-second test at 480p (50 credits)

Before spending 300 or 600 credits, we checked three things at 480p: does Wan use the photo as a product reference rather than the opening frame, does the label survive, and does the presenter say the line as written. All three held: the line came out word for word and the jar keeps its oak lid and FIRLIGHT label in every frame.

Step 2: a 15-second UGC creator ad with dialogue (300 credits)

The prompt asked for four beats: a selfie hook (0–4 s), a close-up of her hands lifting the lid and lighting the wick (4–8 s), a sofa shot by the fireplace (8–11 s) and a selfie sign-off (11–15 s). Wan placed the cuts close to those times, kept the same presenter and sweater across all four shots, and delivered all four lines in order. The only drift is timing: "Honestly?" lands at the end of the second beat instead of the start of the third.

One flaw, which we edited out: in the close-up, Wan made a match appear in her fingers and ignite without a strike. We replaced those three seconds with a slow push-in on a still frame and kept the audio. If your demo depends on a precise hand action, check every frame before you publish, or write the action out of the prompt (for example, start the shot with the candle already lit).

Step 3: a 30-second film in one generation (600 credits)

This is the test that shows both Wan 3.0's strength and its limit. The strength: one 600-credit generation produced a 30-second story that moves from a snowy kitchen through a hallway into the living room, lights the candle and ends on a wide shot as she heads for the door. The jar, the label and the presenter stay consistent for all 30 seconds, and the three spoken lines come out word for word.

The limit: we asked for one continuous shot with "no cuts, no scene jumps", and Wan added three cuts anyway. It also added a soft music bed in the middle although the prompt said no music, and the match again lit itself without a strike, so we cut that section. For an ad, the cuts help the pacing. If your concept depends on a true one-take, budget for a second attempt, and if you need full control of the soundtrack, switch sound off and add your own in the edit.

How much does Wan 3.0 cost per video?

Credits per generation from BuzzVideo's live pricing data on November 10, 2026. Pricing is flat per second: 10 credits at 480p, 20 at 720p and 40 at 1080p. Everything in this post cost 961 credits: 11 for the product photo, 50 for the test, 300 for the 15-second ad and 600 for the 30-second film.

Starter ($14/month billed yearly, 1,900 credits) covers three 30-second 720p Wan clips a month. Seedance 2.5 needs Pro, where 4,900 credits also buy three 30-second 720p clips. See what an ad really costs on BuzzVideo and the pricing page for current plans.

When should you pick Seedance 2.5 or Kling 4.0 instead?

• Your ad needs many references. Seedance 2.5 takes up to 30 images, 10 videos and 10 audio clips per generation; Wan 3.0 takes 10, 5 and 5.
• You need a strict one-take. In our test, Wan 3.0 added cuts to a prompt that asked for none. Test any long-take concept at 480p first.
• You need exact on-screen text or offers. Add prices and captions in the edit, whichever model you use.
• You're making short hooks in volume. For 5–10 second variants, compare Wan 3.0 at 480p with MiniMax H3 and our variant sprint playbook.

If you run AI-generated people in ads, label them. TikTok's ad policy requires disclosure of AI-generated content, and Meta labels ads made or edited with its AI tools. Our guide to AI ad labels covers both.
