Open [Video](https://sloosh.ai/studio/video?video-model=seedance-2.0) and pick Seedance 2.0 in the model chip. 2. Add reference images, videos or audio, or a start and end frame instead (Studio closes the other option once you add one). 3. Write the prompt as a short storyboard: `Shot 1:`, `Shot 2:`, `Shot 3:`. 4. Pick the length (4, 6, 8, 10, 12 or 15 seconds), resolution (up to 4K) and aspect ratio, and leave sound on or switch it off. 5. Check the price on the Generate button, then generate. ## Seedance 2.0 prompting tips - Open with the references: "Use the sneaker in Image 1 as the product." ([Sloosh docs](https://sloosh.ai/docs/seedance-2-0.md)). - Write numbered shots, one camera move per shot. Seedance 2.0 follows numbered shots, not timestamps ([Sloosh docs](https://sloosh.ai/docs/seedance-2-0.md)). - Music goes in brackets `(minimal electronic music)`, sound effects in angle brackets ``, dialogue in curly brackets `{Hello}` ([Sloosh docs](https://sloosh.ai/docs/seedance-2-0.md)). - There's no negative field: add lines like "Keep it subtitle-free; do not generate a logo or watermark." ([Sloosh docs](https://sloosh.ai/docs/seedance-2-0.md)). - 4 or 5 references work best; put the most important first ([Sloosh docs](https://sloosh.ai/docs/seedance-2-0.md)). - Prefer slow, continuous motion; big fast actions are less stable ([Sloosh docs](https://sloosh.ai/docs/seedance-2-0.md)). ## Seedance 2.0 example prompts **Prompt 1** ```text Use the watch in Image 1 as the product; keep its silver case and green dial exactly. Shot 1: Macro close-up of the dial as the second hand ticks, soft side light. Shot 2: The camera slowly orbits to show the crown. Shot 3: Pull back to the watch on a slate stone. (calm piano music) Keep it subtitle-free; do not generate a logo or watermark. ``` **Prompt 2** ```text Refer to the woman in Image 1 and the cafe in Image 2.

Shot 2: Close-up as she looks up and says {Morning already?} Shot 3: Wide shot of the street outside in soft rain. ``` **Prompt 3** ```text Use the camera move in Video 1. Image 1 is the backpack. Shot 1: Follow the move from Video 1 past the backpack on a forest log. Shot 2: Close-up of the zip as a hand opens it. (light acoustic guitar) No subtitles. ``` ## How it compares in Sloosh | | Seedance 2.0 | Seedance 2.0 Fast | Seedance 2.5 | | --- | --- | --- | --- | | Length | 4, 6, 8, 10, 12, 15 s | 4 to 15 s (any whole second) | 4 to 30 s | | Max resolution | 4K | 720p | 1080p | | References (images / videos / audio) | 9 / 3 / 3 | 9 / 3 / 3 | 30 / 10 / 10 | | Prompt style | numbered shots | numbered shots | timed beats | ## Where else it runs ByteDance's launch post links its own Dola app and its cloud playground ([ByteDance Seed launch post](https://seed.bytedance.com/en/blog/official-launch-of-seedance-2-0)). ## Frequently asked questions ### When did Seedance 2.0 come out?
