Those rows are read from the same tables as the [Wan 3.0](https://dreambench.ai/models/wan-3.0) and [Seedance 2.5](https://dreambench.ai/models/seedance-2.5) pages. Both models render up to 30 seconds in one generation, but they don’t reach DreamBench the same way, and the makers document more than DreamBench uses. The table below sets the makers’ own pages, read on November 1, 2026, beside what DreamBench does with each.

## Where each runs: the Video page and Film Studio

DreamBench has two places to make a video. The Video page sends your prompt to one model exactly as you wrote it and returns one clip. Film Studio takes a description of the whole video, writes the scene plan, makes each scene on the model you chose and joins the clips, and any scene can be redone on its own.

Seedance 2.5 is in both. On the Video page it makes one clip of 4 to 30 seconds from words alone, so the full 30 seconds the model can render are yours in one take. In Film Studio it takes the sheets DreamBench builds from your reference images with every scene, and it may cut between shots inside a scene’s clip.

Wan 3.0 runs in Film Studio only, because on DreamBench it starts every clip from a picture. DreamBench makes that opening frame from your reference images, or from the characters, props and places it designs, and Wan 3.0 sets it in motion with sound. A new film is cut into clips of 3 to 12 seconds, so on DreamBench a Wan 3.0 clip is at most 12 seconds, though the model renders 30 elsewhere. A longer video is more clips, joined: up to 30 seconds on Starter, 2 minutes on Plus and 5 minutes on Ultra and Studio.

## Which to pick for your video

**Which matters most in this video?**

- **One long take from a prompt:** Seedance 2.5, on the Video page: one clip of up to 30 seconds, made from your prompt as written. Wan 3.0 isn’t on the Video page, and in a DreamBench film its clips run up to 12 seconds.
- **A short story with cuts:** Seedance 2.5. ByteDance built it to link several shots in one clip, from a set-up to its ending, and DreamBench lets it cut inside a clip. A Wan 3.0 clip on DreamBench keeps one setting: a new place starts the next clip.
- **Every scene from the same frame of your cast:** Wan 3.0. DreamBench draws each clip’s opening frame from your references, so every scene starts on a picture of your cast, and Wan 3.0 animates it. Seedance 2.5 takes the reference sheets with the scene as references instead.
- **A real person from a photo:** Not Seedance 2.5: it refuses a reference that shows a real person’s face, and DreamBench suggests switching model when it does. That refusal is Seedance’s alone; on Wan 3.0, DreamBench makes each opening frame from your reference images. Use only a face you have permission to use.
- **Picture only, or no music:** Seedance 2.5 lets you switch sound off, at the same price. Every Wan 3.0 clip on DreamBench comes with sound; to leave out music, say so in your brief.
- **A 21:9 or 480p version:** Seedance 2.5. It frames 21:9 as well as 1:1, 16:9, 9:16 and 4:3, and renders 480p to try an idea at a lower cost. Wan 3.0 runs at 720p or 1080p in 1:1, 16:9, 9:16 and 4:3.

## Sound, music and spoken languages

Both models generate sound in the same pass as the picture. [Alibaba’s Model Studio guide](https://www.alibabacloud.com/help/en/model-studio/wan3-video-generation-guide) says Wan 3.0 natively outputs dialogue, background music and sound effects, on by default with a switch to turn it off. DreamBench doesn’t send that switch, so every Wan 3.0 clip here has sound. Seedance 2.5’s sound is a setting in the composer, and a second costs the same with it on or off.

On languages, ByteDance is the more specific. [BytePlus lists 11](https://docs.byteplus.com/en/docs/ModelArk/2607688) for Seedance 2.5’s prompts and speech, including Indonesian, Portuguese, Japanese and Arabic. Alibaba publishes no list for Wan 3.0 and says its voices sound natural in more than one language. For a line in a language other than English, write it in that language, in quotation marks, and name the language.

Alibaba’s own platform can also sync a character’s lips to an audio clip you supply. DreamBench doesn’t take a voice recording on either model: the voice comes from the words in the prompt.

## Where Wan 3.0 and Seedance 2.5 part ways

#### What Wan 3.0 does on DreamBench that Seedance 2.5 doesn’t

- Starts every clip from an opening frame of your cast, made by DreamBench from your references.
- Builds scenes from a reference that shows a real person’s face: the real-face refusal DreamBench handles is Seedance’s alone.
- Generates dialogue, music and sound effects on every clip, without a setting to remember.

#### What Seedance 2.5 does on DreamBench that Wan 3.0 doesn’t

- Makes one clip of up to 30 seconds on the Video page, from words alone.
- Cuts between linked shots inside one clip.
- Renders 480p and frames 21:9.
- Lets you switch sound off.

Both makers’ tools go further than DreamBench does. Alibaba’s Wan 3.0 takes documents and web pages as references, edits a clip by instruction and extends it forward or backward; ByteDance’s Seedance 2.5 takes up to 50 references, edits a clip and extends it. On DreamBench, you guide each scene with your prompt and reference images, and change it by giving it new direction.

*Video (seedance-2.5, 21:9, 720p, 15 s, with sound): One 15-second take on [Seedance 2.5](https://dreambench.ai/models/seedance-2.5) in 21:9, the setting changing twice behind the dancer without a cut. A Wan 3.0 clip on DreamBench keeps one setting and frames no 21:9.* [Watch](https://media.dreambench.ai/templates/tpl-g-qm87wcoxpj.mp4)

> Brief: A dancer in flowing ivory silk performs on a dark empty theater stage under one warm spotlight, dust motes drifting in the beam. As she turns, her skirt sweeps across the frame and the theater dissolves behind it into a moonlit forest glade — the dust motes are now fireflies, the stage floor now moss and roots. She continues without pause; another turn, another sweep of silk, and the forest becomes a shallow reflecting pool at dusk, her feet throwing rings of water, droplets hanging in the air. Camera orbits her slowly throughout, never cutting. Soft rim light, drifting particles, dreamlike photoreal.

## Writing a prompt for each

For Seedance 2.5, write a timeline. [BytePlus’s prompt guide](https://docs.byteplus.com/en/docs/ModelArk/2607689) starts with a one-sentence summary, then divides the clip by timestamps or “Shot 1”, “Shot 2”, each with what is seen, the camera, the action, the dialogue and the sound, and ends with what stays the same. Ask for “no subtitles” or “no BGM” when you want none.

For Wan 3.0 on DreamBench, write a single take. Its clip starts on a frame DreamBench has already drawn, so describe what moves from there: where the camera starts and travels, who is in frame and what they do, the setting and the light, then the sound, with spoken lines in quotation marks and any music or effects by name. Alibaba’s own storyboard format, shots of 4 to 6 seconds with timestamps, is for its platform: a DreamBench Wan 3.0 clip doesn’t cut partway through.

In Film Studio you write the brief and DreamBench writes each scene’s prompt for the model, so these habits matter most on Seedance 2.5’s Video page clips. The [Seedance 2.5 prompt guide](https://dreambench.ai/guides/seedance-2-5-prompt-guide) has examples to copy.

## The limits Alibaba and ByteDance name

- Wan 3.0: [Alibaba says](https://www.alibabacloud.com/blog/wan3-0-30-second-ai-video-generation-from-any-input_603452) audio texture and the accuracy of text shown on screen are improving but not yet where it wants them.
- Seedance 2.5: [ByteDance says](https://seed.bytedance.com/en/blog/one-take-creation-flexible-referencing-introducing-seedance-2-5) complex motion can look physically off, and scenes where several subjects interact are not yet fully stable.
- Seedance 2.5 refuses references that show a real person’s face; ByteDance accepts faces from its own models, preset digital characters and verified, authorized people, and DreamBench registers characters it designed from your words when Seedance flags one.

> Where to find them beyond DreamBench: Alibaba offers Wan 3.0 on Alibaba Cloud Model Studio; ByteDance rolls Seedance 2.5 out on Jimeng AI and Doubao, and offers it through BytePlus ModelArk.

## Questions

- **What is the difference between Wan 3.0 and Seedance 2.5?** Both render up to 30 seconds in one generation, with sound. On DreamBench, Seedance 2.5 runs on the Video page and in Film Studio, can cut between linked shots inside one clip, renders 480p to 1080p and lets you switch sound off. Wan 3.0 runs in Film Studio, animates an opening frame made from your references, always has sound and renders 720p or 1080p.
- **Can Wan 3.0 make a 30-second clip on DreamBench?** No. Alibaba’s Wan 3.0 renders up to 30 seconds, but on DreamBench it runs in Film Studio, where a new film is cut into clips of 3 to 12 seconds and joined. For one 30-second clip, use Seedance 2.5 on the Video page.
- **Which is better for dialogue, Wan 3.0 or Seedance 2.5?** It depends on the language. BytePlus lists 11 languages for Seedance 2.5’s speech, from English and Chinese to Indonesian and Arabic. Alibaba publishes no list for Wan 3.0 and says its voices sound natural in more than one language. Both generate dialogue with the picture; Wan 3.0 always does on DreamBench, Seedance 2.5 when sound is on.
- **Can I turn off sound on Wan 3.0?** Not on DreamBench: every Wan 3.0 clip comes with dialogue, music or sound effects. Alibaba’s own API has a switch to turn Wan 3.0’s audio off. Seedance 2.5 on DreamBench lets you switch sound off at the same price per second.
- **Does Wan 3.0 or Seedance 2.5 cut between shots in one clip?** Both makers say their model can. On DreamBench, Seedance 2.5 may cut between linked shots inside a clip; a Wan 3.0 clip keeps one setting, and a new place starts the next clip. Film Studio joins the clips into one video either way.
- **Can I use a photo of a real person with Wan 3.0 or Seedance 2.5?** On Wan 3.0, DreamBench makes each clip’s opening frame from your reference images, and the real-face refusal it warns about is Seedance’s alone. Seedance 2.5 refuses a reference that shows a real person’s face, and DreamBench suggests switching model when it does. Use only your own face or one you have permission to use.
- **Is Wan 3.0 open source?** No. Alibaba offers Wan 3.0 through Alibaba Cloud Model Studio and has not published its weights; the newest Wan video models with published weights are the Wan 2.2 family. On DreamBench, Wan 3.0 and Seedance 2.5 both run in the browser, with no Alibaba Cloud or BytePlus account.
- **Which costs fewer credits, Wan 3.0 or Seedance 2.5?** It depends on the resolution and the length. The table on this page lists each model’s credits per second at each resolution, from the same rates the composer quotes. Seedance 2.5 also renders 480p, its lowest rate, and costs the same with sound on or off. The composer shows a video’s exact cost before you generate.
