Seedance Prompt Generator
Create a focused ByteDance Seedance video prompt with the right shot, camera move, subject, action and lighting.
To use this Seedance prompt generator, fill in the form above, hit generate, and copy what comes back. That is the whole process.
Start with the four required fields: your concept (the subject and setting), what happens in the clip, the mood, and the camera move. Sound or dialogue is optional. So is the include or avoid box. Then pick plain text or JSON and generate.
What comes out is one prompt you can paste straight into Seedance. It carries the shot size, one camera move, subject, action, setting, lighting and a short constraint line. Nothing else. This tool writes the prompt only. You take it to Seedance yourself.
Why bother with a form instead of typing one loose sentence? Because Seedance 2.5 generates up to 30 seconds in a single generation. A clip that long gets decided by a single prompt, so a vague brief leaves much of it to chance. Give the model a clear subject, a clear action and a clear camera move, and it has far less to guess on its own.

How To Use the Seedance Prompt Generator
The form has six boxes and one dropdown. Each writes a different part of the prompt, so it pays to know what goes where before you type. Fill them with intent and the output does the rest.
What Each Input Does
Here is the job of each field.
- Concept. Your subject and setting in one line. Something like “matte black coffee grinder on a marble counter”. This is what the camera looks at and where it sits.
- What happens. The action, written in order. If two things happen one after another, list them that way: beans in, grind, steam rises.
- Mood. The look and feel. Warm morning light, cold blue shadows, flat studio white. This becomes the lighting and tone of the prompt.
- Camera. Movement and framing. Slow push-in, locked-off wide, handheld follow. One clear move works better than three.
- Sound (optional). Dialogue, effects or music. If a character speaks, the line goes here.
- Include or avoid (optional). Things to keep in frame or leave out. “Keep the logo visible”, “no text overlays”.
That order is not random. Dreamina’s prompt guide lays out its own sequence: format, subject, action, environment, camera, look, timing, audio and constraints. The form follows the same logic. Subject first, then action and setting, then camera and look, then audio and constraints. So the prompt comes out in the order a video model expects to read it. It is vendor guidance rather than hard spec, but it is a sane way to brief any shot.
Plain Text or JSON Output
The dropdown decides how the answer is packed. Plain text gives you one paragraph you can paste straight into the prompt box in Seedance. No cleanup, no editing.
JSON keeps each field as its own labelled value. Pick this when you plan to reuse one concept and swap only the camera or the mood later, or when you are building a set of clips and need the parts kept apart. It is also easier to store and read back. For other structured prompt work, there is a separate JSON prompt generator on Feedough.
Copy, Paste and Adjust
Take the output and paste it into Seedance. If the first clip is close but not right, change one input at a time and generate again. Swap the camera move and leave everything else alone. That way you can point at the field that caused the difference.
Take the coffee grinder idea. Start with concept “matte black coffee grinder on a marble counter” and camera “slow push-in”. On the next run, keep the concept and change the camera to “slow orbit”. Only that one line in the prompt shifts, so the change in the clip is easy to read. Change the mood as well and you are back to guessing.
Sound works the same way. For a character moment, type the spoken line into the sound box and keep the other fields fixed. Then adjust the line alone until it lands.
This one-field-at-a-time habit matters more here than in text tools, because a video run takes longer to judge than a paragraph. If you want help shaping prompts for other models first, the AI prompt generator is a decent starting point.

Writing Prompts That Suit Seedance 2.5
Changing one field at a time gets you close to the clip you want. Writing with the model’s own habits in mind gets you closer. ByteDance has been open about what Seedance 2.5 does well and where it still slips. That is useful. You can steer your prompt around the soft spots instead of finding them the hard way.
Use the Sound Field for Audio
Sound here is not a layer added after the fact. The ByteDance Seed launch post for Seedance 2.5 says audio and visuals are generated together in the same pass and kept in sync. So the sound box shapes the shot just as much as the camera box does.
Write it like a short shot list. Name the effect and roughly where it lands: “beans grinding, then the hiss of steam”. If characters talk, keep one clear speaker per line. Two voices packed into one sentence give the model two things to place at once, and then you cannot tell which line went wrong.
Plan Timing for Longer Clips
One generation covers up to 30 seconds. Split the clip into three or four beats and write them in order. Say, 0 to 6 seconds the grinder starts, 6 to 14 the steam rises, 14 to 24 the hand lifts the cup, 24 to 30 the cup sets down. That four-part split mirrors how Dreamina times its own 30-second example.
Drop those beats into the “what happens” box as a short sequence. The generator keeps the order, so the model reads your clip as a timeline instead of a pile of actions happening all at once.
Keep Scenes Simple Where the Model Is Weak
That same launch post names two soft spots: physical plausibility when motion gets complex, and stability when several subjects interact in one scene. Which tells you where not to be clever.
Keep the cast small and the action easy to believe. One subject doing one clear thing beats three people passing a prop around. If the clip needs two characters, give each a beat of their own rather than a shared action. And use the include or avoid box to pin down what tends to drift: “both hands stay on the grinder”, “only one person speaks at a time”.
Two things to check before you render. The launch post does not state output resolution, so look at your own Seedance platform for that. And the model is rolling out on Jimeng AI and Doubao Pro, with the API via BytePlus ModelArk listed as coming soon. If you are still deciding where to run your clips, our AI video generators roundup covers the wider field.
Final Thoughts
There is one next step here. Fill in the four required boxes: concept, what happens, mood and camera. Run the generator and paste the prompt into Seedance. Leave sound and the include or avoid box empty on the first pass, unless the clip genuinely needs them.
Then look at what came back and change one input. Maybe the camera move, maybe the mood. Generate again and read the two prompts side by side. That single swap tells you which field pulls your clip in which direction, and it builds the habit that keeps your runs honest.
The concept box is waiting right above this text. Start there.
