Seedance 2.0 is ByteDance's highest-quality model in the 2.0 series. It makes video and sound together and holds a product's or character's look from reference images, videos and audio.
## When to use it
- Product turntables and short ads that need the product to stay accurate.
- Reusing a camera move from a reference video, or a voice from an audio clip.
- It follows numbered shots, not timestamps. For timed beats, use [Seedance 2.5](https://sloosh.ai/docs/seedance-2-5.md).
## How to prompt it
- Open with the references: "Use the sneaker in Image 1 as the product."
- Write a storyboard: `Shot 1:`, `Shot 2:`, `Shot 3:`. One camera move per shot, with the action and the sound.
- Music goes in brackets `(minimal electronic music)`, sound effects in angle brackets ``, dialogue in curly brackets `{Hello}`.
- There's no negative field. Add lines like "Keep it subtitle-free; do not generate a logo or watermark."
- 4 or 5 references work best: put the most important first, and don't fill every slot.
- Prefer slow, continuous motion; big fast actions are less stable.
## Example
One product reference and a three-shot storyboard.

Use the sneaker in Image 1 as the product; keep its white mesh, sage-green panels and white foam sole consistent.

Shot 2: A hand enters frame, lifts the sneaker and turns it to show the sole.
Shot 3: The camera slowly pulls back to a wide shot of the pedestal in clean studio light. (minimal electronic music)

## Frequently asked questions
### Can Seedance 2.0 make 4K video in Sloosh?
Yes. Seedance 2.0 offers 4K in Sloosh, as well as 480p, 720p and 1080p, and it is the only Seedance model there that does. 4K outputs need a Pro or Max plan; [Plans and credits](https://sloosh.ai/docs/plans-and-credits.md) explains plans.
### How many references should I give Seedance 2.0?
BytePlus recommends 4 or 5 references for Seedance 2.0, such as one or two character images, one scene, one camera-move video and one audio clip, even though Sloosh accepts up to 9 images and 3 videos. Put the most important reference first and don't fill every slot.
### How do I add music, sound effects and dialogue in Seedance 2.0?
Seedance 2.0 reads three markers: music in brackets, `(minimal electronic music)`; sound effects in angle brackets, ``; and dialogue in curly brackets, `{Hello}`. BytePlus advises against mixing Chinese and English in one line of dialogue.
### Does Seedance 2.0 copy the sound of my reference video in Sloosh?
No, not in Spacelab runs. Sloosh removes the soundtrack from Seedance reference videos before using them, because Seedance copies a reference's audio and the result can then be blocked as copyrighted music. Describe the sound you want in the prompt instead.
### Why does my Seedance 2.0 video have subtitles or a watermark?
Seedance 2.0 sometimes adds stray subtitles, logos or watermarks, and it has no negative prompt field. Add constraint lines to the prompt, such as "Keep it subtitle-free; do not generate a logo or watermark.", which is the wording BytePlus recommends.
