Wan 3.0 vs Seedance 2.5

Those rows are read from the same tables as the Wan 3.0 and 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.

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.

Both models generate sound in the same pass as the picture. Alibaba’s Model Studio 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 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.

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.

For Seedance 2.5, write a timeline. BytePlus’s prompt guide 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 has examples to copy.

• Wan 3.0: Alibaba says audio texture and the accuracy of text shown on screen are improving but not yet where it wants them.
• Seedance 2.5: ByteDance says 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.
