Seedance Prompt Translation: Write in Your Own Language

Seedance prompt translation lets you write generation instructions in your own language. The studio translates detected non-English instructions into English before generation, leaves English prompts unchanged, and protects short quoted text. If translation fails, it keeps your original prompt. This helps you describe a scene without translating every instruction yourself; it does not guarantee that generated dialogue, captions, or lettering will appear correctly in your chosen language.

Updated October 9, 2026 · Instructions for the current studio

Open the Seedance studio and use the normal prompt field. There is no separate translation step to complete. Choose the generation mode and model appropriate to your task, write a clear request, and inspect the result against that request. The cover illustration is a visual metaphor for translating creative instructions, not a screenshot or a demonstrated generation result.

Separate three different language choices

A language setting can refer to the interface, the instructions you submit, or language inside the generated media. Those are different decisions.

For example, a Spanish instruction asking for a slow camera move can be translated into English while a short quoted Spanish sign remains in Spanish. Whether the sign is legible in the resulting frame is another question. A correct instruction is useful, but the finished image or video still needs review.

If your immediate problem is reading controls, start with the image-to-video language and controls guide. The W3C explains how web pages declare their language; that concerns the page itself, rather than a generation model's interpretation of your scene.

Write the scene clearly in the language you know best

Use ordinary sentences and concrete nouns. Translation cannot resolve a brief that is ambiguous in its original language. “Make this more exciting” gives less direction than “keep the boat centered and move the camera slowly closer while the water ripples.”

A useful request describes four things: the subject, its action, the camera or composition, and any details that must remain stable. You do not need a special syntax. Put the most consequential instruction early, and avoid combining unrelated scenes in one sentence.

Here is a Spanish example for a simple visual test:

Un velero rojo flota en un lago tranquilo. La cámara avanza lentamente hacia el barco. Mantén el casco rojo y el horizonte recto. No añadas personas ni texto.

The intended meaning is a red sailboat floating on a calm lake, a slow camera move toward it, a stable red hull and straight horizon, and no added people or text. This is an example request, not a report of a successful render. The result should be judged on those visible conditions.

A comparable Chinese instruction is:

一艘红色帆船漂浮在平静的湖面上。镜头缓慢向帆船推进。保持红色船身和水平的地平线。不要添加人物或文字。

Use whichever version you can edit accurately. A prompt written in unfamiliar English can lose an essential detail before generation even begins. If a collaborator provides a translation, compare the subject, direction, negation, and numbers with your own brief rather than judging it only by how polished it sounds.

Use short quotations for literal words

Short quoted phrases receive special treatment so words intended to appear or be spoken can remain as written while surrounding instructions are translated. Standard double quotation marks or paired typographic quotation marks are a practical choice.

For an image request, you might write:

Crea una ilustración de una pequeña cafetería junto al mar. En el cartel sobre la puerta aparece "Buenos días". Mantén el fondo sencillo y no añadas otras palabras.

The quoted phrase is the intended sign text. The surrounding Spanish describes the cafe and the composition. Short quotations help separate literal words from instructions, but they do not force correct rendering. Check the accent, spacing, letters, and placement if text appears.

Keep the literal phrase short and leave the surrounding instructions outside the quotes. Wrapping the entire prompt in quotation marks is different: long quotations, or quotations that contain most of the request, may be treated as instructions to translate. For lengthy captions, subtitles, or exact commercial copy, add the approved text in an editor after generation.

The same distinction applies to a requested spoken line. Preserving the words in the submitted instruction does not prove that the selected video workflow supports the audio behavior you need. Check the active model and controls, then listen to the complete output. Do not infer voice, accent, or timing guarantees from quotation marks.

Check the mode before checking the language

A well-written translated instruction cannot correct a mismatched mode. Use text-to-video for a text-led scene, image-to-video when you want to animate a permitted still, or an available image mode for a still-image task. The model selected in the studio determines which modes and settings are offered.

For image-to-video, describe the change over time rather than repeating every visible detail in the source. If the image already shows the boat, “slow forward camera movement, small water ripples, keep the hull stable” gives the motion request a clearer job than an elaborate replacement scene.

For image-to-image, name what to preserve and what to change. The Seedream first-edit guide provides a bounded example. Prompt translation applies to detected non-English instructions in the available image workflow too, but it does not create extra editing controls.

Before submitting, confirm the visible model, mode, aspect ratio, relevant quality settings, and credit cost. Keep those settings fixed if you later compare two language versions. Otherwise a difference in the output could come from a changed model or setting rather than the wording.

Review meaning before judging visual polish

Watch the entire clip or examine the complete still. A pleasing result can still reverse a direction, omit a protected object, or misunderstand a negation. Compare it with a short plain-language description of your intention.

Save your original prompt with the output so a reviewer can understand the intended scene. If you compare a native-language request with an English version, use the same source and settings and treat the comparison as a practical test. Generated results vary; one pair cannot establish that a language always works better.

For motion-specific evaluation, the camera-move review guide explains how to inspect the opening, hardest movement, and final frame. Translation is only one part of getting a usable clip.

When a prompt seems to go through unchanged

Automatic detection has limits. Brief fragments such as a single word, mixed-language shorthand, or a brand name may not provide enough language information. A prompt containing mostly English with a few foreign words can also remain unchanged.

Try a complete sentence in your preferred language. Replace idioms with a concrete description if their visual meaning matters. Keep names and literal text separate from scene instructions. You can also submit your own reviewed English translation when an important detail repeatedly fails, without changing the model and source at the same time.

If the translation service cannot return a usable translation, the studio retains the original instruction. That fallback prevents a translation failure from discarding your request. It is not a signal that the model understood every word, and it does not bypass normal safety checks or account requirements.

A failed generation is a different problem. Follow the generation-failed guide for that case. Do not assume that a timeout or a rejected upload proves that prompt translation caused it.

Scope, authorship, and limits

This guide is maintained by the Seedance 2.5 Editorial Team and describes the studio's prompt workflow as of October 9, 2026. Seedance2-5.video is an independent platform and is not affiliated with ByteDance. The translation behavior described here belongs to this studio; other services offering similarly named models can handle prompts differently.

The examples are suggested inputs, not performance tests or guarantees. Keep source-image permission, output review, and exact-text approval separate from the convenience of writing instructions in your own language. Start with a small request whose success you can recognize, then expand only after the result meets that need.

Frequently asked questions

Can I write a Seedance prompt in another language?

Yes. The studio automatically translates detected non-English generation instructions into English before sending them to the generation model. Detection is imperfect, so very short or mixed-language prompts may pass through unchanged.

Does prompt translation guarantee dialogue or captions in my language?

No. Translating instructions is separate from producing accurate speech, captions, or lettering. Put short literal text in quotation marks and review any generated words or audio independently.

What happens if automatic prompt translation fails?

The studio keeps the original prompt and continues the normal generation workflow. This fallback preserves your request, but it does not guarantee how the generation model will interpret it.

Should I translate an English prompt before submitting it?

No. English instructions remain unchanged by the translation layer. Use clear descriptions of the subject, action, framing, and details that should stay stable.
