To write a better Seedance 2.5 prompt, assign each reference asset a clear job, state the scene in one sentence, lay out the action and camera as a continuous timeline, then add rules that apply throughout. That structure gives the model clearer direction about what to show, when to show it, and which parts of your references matter.
How should you structure a Seedance 2.5 prompt?
Use four parts: asset mapping, a one-sentence brief, a timed shot sequence, and global constraints. The Seedance Prompting Guide recommends this structure for prompts that combine references and scene instructions.
- Map the assets. Identify each uploaded image, video, or audio clip in upload order and say exactly what it controls: appearance, movement, setting, camera, style, voice, or sound.
- Write one brief sentence. Name the subject, location, event, genre or style, and general camera treatment.
- Describe a continuous timeline. Break the clip into consecutive time ranges. For each, specify the visible action and camera movement, and include dialogue or sound cues when relevant.
- Set global constraints. State requirements that hold for the whole clip, such as lighting, palette, framing, ambience, aspect ratio, subtitles, or music.
Keep the brief focused on what happens rather than stacking adjectives. For example, “a quiet, cinematic scene in a rainy bookshop, following the lead as they find a letter” gives the timeline a clear event to develop. A useful prompt is a small, filmable sequence: action, camera, and sound working together.

Use consecutive time ranges, such as “0–3 seconds,” “3–7 seconds,” and “7–15 seconds.” Avoid unexplained gaps, and make sure each beat contains an amount of action that fits its duration. Plain terms such as “slow push-in,” “pan,” “tracking shot,” and “close-up” are useful when they remove ambiguity.
#1 Best Overall
For a short clip, give the scene a manageable progression rather than asking for too many events at once. A panda cub could start rolling, be followed by the camera, stop, look toward the camera, and settle. Each beat should lead naturally to the next; if an action, camera change, or sound cue matters, place it at the time it should occur.
Reusable prompt example
The following is a template, not a tested prompt or a guarantee of a particular result:
Asset mapping: Image 1 controls the lead character’s appearance; Video 1 is a reference for camera movement only; Audio 1 supplies the lead’s voice. Do not copy other content from the references.
Brief: A quiet, cinematic scene in a rainy bookshop, following the lead as they find a letter.
0–3 seconds: Begin in a medium shot as the lead enters and notices the letter on the counter. The camera tracks slowly left.
3–7 seconds: Move to a close-up as the lead opens the letter and reacts with restrained surprise. Keep the face and clothing consistent with Image 1.
Throughout: Soft rain and room tone only; no music or subtitles; muted blue-gray lighting.How should you assign image, video, and audio references?
Say what each reference contributes instead of assuming the model will infer it from the asset or labels inside an image. One image might set a character’s appearance; a video might guide action order or camera rhythm; another image might contribute color or lighting. Give each asset one explicit role where possible, and say what not to copy when a reference should influence only one aspect.
The Seedance Prompting Guide describes support for subject and style references, motion and camera references, storyboards and keyframes, editing, extension, and asset assembly. Its input recommendations are up to 30 images, up to 10 video clips totaling 30 seconds, and up to 10 audio clips totaling 30 seconds. It also recommends uncluttered reference images, fewer than 15 simple storyboard panels, and simple geometry for blockouts. These are guide recommendations, not a promise that every maximum will work equally well for every task.
Choose references according to the job
- Identity or style: Use image references to guide a subject’s appearance, visual style, color, or lighting, and name the intended role.
- Movement or camera: Specify whether a video contributes action order, motion, or camera behavior. Avoid asking one reference to control several unrelated things unless that is intentional.
- Story structure: Use storyboards or keyframes to convey shot progression. The guide says separate keyframe images generally align more strictly than a storyboard grid.
- Voice or sound: Identify whether audio supplies a character voice, dialogue, melody, or rhythm. For generated audio, describe what should be heard and when.
When should you use a reference versus editing or extending a clip?
“Use this as a reference” and “continue this exact clip” describe different levels of control. The guide distinguishes unlocked reference tasks from locked tasks:
- Unlocked references—ordinary references, storyboards, and keyframes—guide visual or semantic choices while duration and aspect ratio remain independent.
- Locked tasks—editing, first/last-frame generation, and extension—use an input that occupies part of the output timeline or determines its aspect ratio. Some generation settings cannot be changed freely.
Use an unlocked reference when you want guidance on identity, style, or story but need flexibility in the overall output. Choose a locked task when the result must edit or continue existing media, or begin or end on a particular frame.
How do you prompt dialogue and sound?
When using supplied audio, state whether it is a voice, dialogue, melody, or rhythm reference. For sound the model should generate, specify both the sounds and their timing. Global instructions can set persistent rules such as “wind and footsteps only,” “no music,” or “no subtitles.” The prompting guide says dialogue is supported in more than ten languages, but that is a product-guide statement, not a claim about equal performance in every language.

A USB microphone is one possible way to record source audio for a voice reference; it is optional, not a Seedance requirement. The cited sources do not identify a particular microphone to use.

In its July 31, 2026 launch announcement, ByteDance said Seedance 2.5 can generate audio-video clips up to 30 seconds in one pass, accept up to 30 images, 10 video clips, and 10 audio clips as references, and support multiple rounds of extension. Its current model page describes 30-second storytelling and says a generated video can be extended twice. A 30-second generation and a workflow that extends a generated clip are distinct; do not treat an extended workflow as one 30-second generation.
ByteDance also describes connected shots within a generation, multimodal references, and timestamp-level edits. These are the developer’s capability statements, not independent performance tests or guarantees that a prompt will produce a publish-ready video on the first try.
ByteDance says complex motions can still lack physical plausibility and scenes with interactions among multiple subjects can be unstable. For choreography, object interactions, or scenes with several active characters, inspect the result carefully and refine the prompt or references where motion or continuity breaks down.

Where can you access Seedance 2.5?
ByteDance’s July 31, 2026 announcement said Seedance 2.5 was rolling out on Jimeng AI, Doubao Pro, and other platforms, with API access coming through BytePlus ModelArk. The current model page includes an API access action. Availability, pricing, and geographic access can change and are not established by those statements, so check the official access page for current details.
