# Seedance 2.5 prompt generator

URL: https://dreambench.ai/tools/seedance-prompt-generator

A preset of the [AI video prompt generator](https://dreambench.ai/tools/ai-video-prompt-generator): the same engine, set up for this one job.

Seedance 2.5 can hold one take for up to 30 seconds, or cut between linked shots inside a single clip, and it makes the soundtrack with the picture. This guide shows how to prompt it, and its generator writes for both: one continuous take, or two or three numbered shots with the seconds each one runs, the same subject carried across the cuts.

## What is a Seedance 2.5 prompt generator?

It writes a prompt for ByteDance's Seedance 2.5 from your choices: one take of up to 30 seconds, or two or three numbered, timed shots in one clip, with light, camera and sound, asking only for what Seedance can make. It is part of every DreamBench plan, from $9.99 a month.

## How to write a Seedance 2.5 prompt

1. Describe the moment: Who or what is in frame, what they do and where. A Seedance 2.5 clip has room for a moment to open, develop and land, so describe the whole beat, not a single pose.
2. Choose a take or shots: One continuous take, or two or three linked shots from a wide opening to a close-up. Then the length, from 5 to 30 seconds, the frame, the light, the lens, the move and the sound.
3. Copy or run it: Linked shots come out numbered, with the seconds each one runs. The first time, create a free account and choose a plan, then copy the prompt into any tool that runs Seedance 2.5, or run it on DreamBench.

## How a Seedance 2.5 prompt is built

1. The frame and how the clip runs: Widescreen, vertical, square, 4:3 or cinematic 21:9, then one continuous take with no cuts, or the number of linked shots, said first.
2. The whole moment: Who is in it, what they do and where. A clip can run 30 seconds, so describe the beat from start to finish: what happens first, what turns, how it lands.
3. The light: The source and its side, and what falls to shadow, the same in every shot of the clip.
4. The shots, numbered and timed: Linked shots come as Shot 1, Shot 2 and Shot 3, each with its seconds in whole numbers and its size, from a wide opening to a close-up as the moment lands.
5. The same subject in every shot: A line that keeps the subject, the place and the light across the cuts. ByteDance reports smoother transitions in 2.5, with the main subject keeping its look.
6. The sound last: Ambience, a spoken line, a music bed, or silence: Seedance 2.5 makes sound together with the picture, or leaves it out.

## Example prompts

**Thirty seconds in one take (Seedance 2.5).** One continuous take of 30 seconds, long enough for the moment to open, build and land, with the ambience under it.

```text
Widescreen 16:9, one continuous 30-second take with no cuts. Two friends in raincoats share one umbrella at a night bus stop, laughing as the bus finally pulls in, on a rainy city street, neon reflected in the puddles. Light: night, lit only by the practical lights in the scene from behind the subject, the camera shooting into the light from the shadow side, a rim of light on the edges; the exposure holds the subject; no fill from the camera side. Medium shot on a 35mm lens at a few metres: the subject and the room both readable, little distortion. The camera is locked off; nothing moves but the scene. Photoreal, shot on film: natural colour, gentle grain, true skin. Sound: the scene's own ambience, no music. No text, no captions, no watermark.
```

**Three linked shots (Seedance 2.5).** Fifteen seconds in three shots: a wide opening, a medium shot with the move, and a close-up as the moment lands, each timed in whole seconds.

```text
Vertical 9:16, one 15-second clip in three linked shots. A baker in a flour-dusted apron pulls a tray of loaves from the oven, breaks one open and smiles at the steam, in a small bakery before dawn. Light: night, lit only by the practical lights in the scene from camera-left, so the subject's camera-right side falls to shadow; the exposure holds the subject; no fill from the camera side. Shot 1 (0–5 s): wide shot, the place and the subject in it. Shot 2 (5–10 s): medium shot on a 50mm lens at a couple of metres: natural proportions, the background softening behind the subject. One move only: a slow push-in that ends close on the subject. Shot 3 (10–15 s): close-up on the subject as the moment lands. The same subject, place and light in every shot. Photoreal, shot on film: natural colour, gentle grain, true skin. Sound: the scene's own ambience, no music. No text, no captions, no watermark.
```

**A line in Spanish (Seedance 2.5).** A 10-second cinematic take with a line typed in the language it should be spoken in, here Spanish.

```text
Cinematic 21:9, one continuous 10-second take with no cuts. An old fisherman in a yellow oilskin mends a net on the harbour wall and calls to his grandson, in a small fishing port at dawn. Light: low golden-hour sun from behind the subject, the camera shooting into the light from the shadow side, a rim of light on the edges; the exposure holds the subject; no fill from the camera side. Close-up on an 85mm lens from six metres: the background compressed and soft, only the subject sharp. One move only: a slow push-in that ends close on the subject. Photoreal, shot on film: natural colour, gentle grain, true skin. Sound: ambience and one spoken line, "La marea está cambiando, ven." No text, no captions, no watermark.
```

## Common mistakes

- A pose instead of a moment: Thirty seconds of one held action look frozen. Give the clip a beginning, a turn and an end.
- Shots too short to read: Three shots in five seconds leave each under two. The generator offers linked shots from 10 seconds up, so no shot runs much under three seconds.
- A crowd that interacts: ByteDance says scenes where several subjects interact are not yet fully stable. Keep one clear subject and one main action.
- Complex physical motion: ByteDance says complex motion can look physically off: acrobatics and juggling are where it shows. Slower, simpler action holds together.
- A new subject in the last shot: A character or a place that appears only in Shot 3 breaks the link between the shots. Keep the subject, the place and the light, and let the shot size change.
- A real face as a reference image: Seedance won't accept a reference image that shows a real person's face. Describe the person in words, or choose another model for that video.

## Works with

- What it takes: Your own words: who is in the shot, what they do and where. No photo is needed.
- What you get: A prompt as plain text.
- DreamBench's composer: Paste it into Video on Seedance 2.5, which sends your words to the model as written, at 480p, 720p or 1080p.
- Dreamina: ByteDance's own creative app runs Seedance from the same plain-text prompt.
- The BytePlus API: Send the prompt as text; its numbered shots are plain text too.

## Which model it writes for, and its limits

The Seedance 2.5 prompt generator writes for [Seedance 2.5](https://dreambench.ai/models/seedance-2.5), within what it can make on DreamBench.

| | Seedance 2.5 |
|---|---|
| Lengths | 5, 10, 15, 20 or 30 seconds |
| Frames | 16:9, 9:16, 1:1, 4:3 or 21:9 |
| Sound | On or off: ambience, a spoken line or a music bed |
| Shots | One take, or two or three linked shots from 10 seconds |
| Dialogue | One line, said in the scene |
| Prompt format | Plain text |

- Up to 30 seconds in one clip: The length runs from 5 to 30 seconds, long enough for a full exchange or a scene that builds to its moment, and the prompt names it, so the action is paced to the clip.
- Linked shots, numbered and timed: Pick two or three shots and the prompt lays them out as Shot 1, Shot 2 and Shot 3, each with its seconds and its size, from a wide opening to a close-up as the moment lands.
- The same subject across the cuts: ByteDance reports smoother transitions between shots in 2.5, with the main subject keeping its look. The prompt asks for the same subject, place and light in every shot.
- Sound that follows the picture: Seedance 2.5 makes dialogue, ambience and effects together with the picture. Choose ambience, a spoken line or a music bed, or silent if you only want the picture.

**Where it fails.**
- ByteDance says complex motion can look physically off.
- Scenes where several subjects interact are not yet fully stable, ByteDance says.
- Seedance won't accept a reference image that shows a real person's face.

## Seedance 2.5 prompt generator FAQ

- **How do I write a prompt for Seedance 2.5?** To write a prompt for Seedance 2.5, open with the frame and how the clip runs, one continuous take or two or three numbered shots, then who is in it, what they do and where, the light, the camera and the sound. A clip can run 30 seconds, so describe the whole moment: what happens first, what turns, how it lands. The generator writes it in that order.
- **Can Seedance 2.5 put several shots in one clip?** Yes. One clip can cut between linked shots, and ByteDance reports smoother transitions with the main subject keeping its look across the cuts. Choose two or three shots and the prompt numbers them, gives each its seconds and moves from a wide opening to a close-up, the same subject and light in each.
- **How long can a Seedance 2.5 clip be?** Up to 30 seconds in one generation, ByteDance says. The generator offers 5, 10, 15, 20 or 30, and linked shots from 10 seconds up, so no shot runs much under three seconds. Of the three models here, Seedance is the one that runs 30 seconds and cuts between shots in one clip; a DreamBench video can be longer still, because the composer joins clips.
- **How do I write a multi-shot prompt for Seedance?** A Seedance multi-shot prompt numbers the shots and gives each its span in seconds: Shot 1 (0–5 s) wide, Shot 2 (5–10 s) medium with the one camera move, Shot 3 (10–15 s) close-up as the moment lands. Keep one subject, one place and one light across the cuts. ByteDance's own examples time their segments as 0–5s and 6–10s; this generator writes whole seconds so no shot runs under three.
- **How do I make a character speak in Seedance?** Choose a spoken line and type it: the generator puts it in quotes after the person who says it, so the voice belongs to someone on screen, and Seedance 2.5 makes the voice with the picture. Keep it short enough to say in the clip, and type it in the language it should be spoken in.
- **Can I use reference images with a Seedance prompt?** This generator writes text only. Seedance 2.5 takes reference images in ByteDance's own apps and in the DreamBench composer, where a scene's references, a product, a place, a character sheet, go to the model with the prompt; it refuses any image that shows a real person's face, so describe a person in words instead. The prompt then says only what moves.
- **Does Seedance take a negative prompt?** This generator writes none: it closes with one line, no text, no captions, no watermark, and puts everything else as a positive direction, which video models follow more reliably than a list of exclusions. If the tool you paste into offers a separate negative field, keep it to a few short nouns and say the rest positively.
- **How long can a Seedance prompt be?** 60 to 150 words for one take covers the frame, the moment, the light, the camera and the sound without repeating itself; a three-shot prompt runs longer, because each shot carries its seconds and its size. That is what this generator writes, and it pastes as plain text into Dreamina, the BytePlus API and the DreamBench composer.
- **How do I write a Seedance image to video prompt?** Describe only what moves and what the camera does; the picture already sets the subject, the light and the look, so a sentence about the motion and one about the sound is enough. This generator writes text-to-video prompts; on DreamBench the product video maker runs Seedance 2.0 from one product photo, with the labels asked to stay as photographed.
- **Does a Seedance 2.0 prompt work on Seedance 2.5?** Yes: the structure carries over. Seedance 2.5 runs longer, up to 30 seconds against 15 on 2.0, so a 2.0 prompt often describes less than a 2.5 clip has room for. Add the turn and the landing, or split it into linked shots. DreamBench runs both models; this generator writes for 2.5.
- **Can the dialogue be in another language?** Type the line in the language it should be spoken in; the generator writes its own sentences in English and passes your line on as typed. ByteDance's Seedance 2.5 pages don't list the spoken languages, so try a short line first and listen before you build a longer clip on it.
- **What does Seedance 2.5 find hard, and does this generator need a plan?** ByteDance is candid about it: complex motion can look physically off, and scenes where several subjects interact are not yet fully stable, so the generator keeps to one clear subject and one main action. The generator itself needs a DreamBench plan: you create an account on the way, and the button shows the price in credits before you press it.
- **How much does the Seedance 2.5 prompt generator cost?** Each prompt uses 11 credits from your DreamBench plan, and the same prompt again uses none. Starter, $9.99 a month, includes 1,100 credits a month, about 100 prompts, plus AI video and the image tools.
- **Do I need an account to use the Seedance 2.5 prompt generator?** Yes: a free account and a DreamBench plan. The tools are part of every plan, from Starter at $9.99 a month.
