如何写出更好的 Seedance 2.5 视频 Prompt

Seedance 2.5 是 HiArt 上字节跳动最长的多模态视频模型:最长 30 秒、原生同步音频,以及最多 50 个媒体文件 的全能参考。结果仍然高度依赖 Prompt——尤其是多个 @ 参考共享一次生成时,如何分配角色。
本指南覆盖适合更长、参考更丰富片段的语法与写法。若需产品概览,请先读 Seedance 2.5 是什么?模型页

可以上传什么

写 Prompt 前先规划素材——Seedance 2.5 可比 Seedance 2.0 接收更多文件,未在 Prompt 中引用的上传会浪费积分并干扰模型。

输出规格

  • 时长:4–30 秒(自选)
  • 原生同步对白、音效与背景音乐,支持口型同步
  • 分辨率:480p 或 720p

须知

  • 上传内容中的真实人脸会因合规被拦截——请使用风格化或非写实参考。
  • Prompt 中应提及每一个已上传文件;孤儿参考会破坏一致性。
  • 20–30 秒脚本务必写清节拍——不要丢一整段无时间标记的文字。
  • 若需要 15 秒内的 1080p?在 2.5 或 Fast 上锁定 Prompt 后,切到 Seedance 2.0

@ 参考系统

每个上传素材都有槽位——@Image1@Video2@Audio1 等。模型不会自行推断用途,必须在 Prompt 里明确说明。
@Image1    @Image2    @Image3  … 最高 @Image30
@Video1    @Video2   … 最高 @Video10
@Audio1    @Audio2   … 最高 @Audio10

常见参考角色

用途
示例
首帧
@Image1 as the first frame
尾帧
@Image2 as the last frame
角色外观
@Image1's character as the subject
多镜头身份锁定
keep the character consistent with @Image1 @Image2 @Image3
场景 / 背景
scene references @Image8
运镜
reference @Video1's camera movement
动作 / 编排
reference @Video1's action choreography
特效 / 转场
completely reference @Video1's effects and transitions
节奏
video rhythm references @Video1
背景音乐
BGM references @Audio1
声线 / 对白语气
voice tone references @Audio2
音效
sound effects reference @Video3's audio
镜头需要时可以叠多个角色——这对 2.5 更大的参考额度尤其有用:
@Image1's character as the subject, wardrobe from @Image2, scene references
@Image3 @Image4, camera and pacing from @Video1, BGM references @Audio1,
dialogue tone references @Audio2

如何组织 Prompt

强 Prompt 通常按这个顺序:
[Subject] + [Scene] + [Action/Motion] + [Camera] +
[Timing] + [Effects/Transitions] + [Audio] + [Style/Mood]
超过约 10 秒——尤其是 20–30 秒的 Seedance 2.5 渲染——请把动作拆成带时间的节拍:
0–5s: opening hook, establish subject and location
5–12s: develop action / product benefit
12–20s: climax, key reveal, or dialogue turn
20–30s: resolution, brand end card, music settle

镜头语言速查

Seedance 对标准电影术语响应良好。把运动与景别组合,可获得更细控制。

在 Seedance 2.5 上好用的例子

用多张参考锁定角色一致

使用多张外观图,再编排更长场景:
Keep the character consistent with @Image1 @Image2 @Image3. Wardrobe from
@Image4. Scene references @Image5.
0–6s: The character walks into a warm apartment hallway, medium shot,
natural dialogue under breath.
6–14s: Close-up — they pause at the door, exhale, soft smile.
14–22s: Door opens; child and pet rush in. Interior references @Image6.
22–30s: Wide shot of the living room, warm practical lights, music settles.
BGM references @Audio1. Voice tone references @Audio2.

多参考驱动的音乐卡点剪辑

@Image1 through @Image8 are keyframe looks for the same performer.
Match the cut rhythm of @Video1 and the beat of @Audio1.
0–8s: Close-ups and handheld energy, lip sync to @Audio1.
8–18s: Wider dance moves; completely reference @Video2's choreography.
18–30s: Orbit around the performer, neon city lights, final freeze on logo.
More dynamic motion; dreamlike grade; beat-synced transitions.

复刻运镜并拉长故事

Reference @Image1's character in @Image2's elevator.
Completely reference @Video1's camera movements and facial expressions
for the first half.
0–8s: Hitchcock zoom during the fear beat, then orbit the cabin.
8–16s: Doors open; follow shot into a lobby that references @Image3.
16–24s: Character walks to glass exit; rain streaks on windows.
24–30s: Exterior night street, pull back to wide, music drops to silence.
Ambient SFX; tense piano BGM.

带旁白的 30 秒产品故事

Hero product is @Image1. Lifestyle context from @Image2 @Image3.
Editing energy references @Video1. Voiceover cadence references @Audio1.
0–5s: Product rotates into frame, macro on texture and logo.
5–12s: Angle transitions — front, side, detail — with scanning highlight.
12–20s: Product in real usage; hands and environment stay clean.
20–26s: Benefit line as natural dialogue / VO synced to picture.
26–30s: Hero end frame, brand tagline, music resolves.
Sound: BGM references @Audio2; add subtle product interaction SFX.

风格与音频修饰词

在 Prompt 末尾追加短句,引导画面与声音:
  • 视觉: Cinematic quality, film grain, shallow depth of field · 2.35:1 widescreen, 24fps · Anime style / Photorealistic
  • 情绪: Tense and suspenseful · Warm and healing · Epic and grand
  • 音频: Background music: grand and majestic · Beat-synced transitions · Lip-synced dialogue · Voice tone reference @Audio1

更长片段的快速工作流

  1. 确定视频类型——广告、短剧、MV、产品故事、教学。
  2. 只收集会引用的参考,并为每个映射 @ 槽位。
  3. 为完整时长写节拍(尤其超过 15 秒时)。
  4. 给每个 @ 参考分配角色——外观、运镜、BGM、旁白等。
  5. 在 Seedance 2.5 上以 480p/720p 生成;下一轮收紧含糊句子。
  6. 若之后需要 15 秒内 1080p,把锁定的 Prompt 迁到 Seedance 2.0。

常见错误

  1. 模糊参考 — 只写 "reference @Video1",却不说明运镜、动作或节奏。
  2. 未使用的上传 — 挂了二十张图,Prompt 只提五张。
  3. 无时间的 30 秒脚本 — 一整段文字没有节拍标记,很少成功。
  4. 冲突的镜头说明 — 同一段既要静止又要环绕。
  5. 前几秒塞太满 — 开场 4 秒内三次场景切换。
  6. 没有音频方向 — 在 2.5 上,声音与口型是重要质量杠杆。
  7. 时长错配 — 30 节拍大纲却选了 10 秒输出。
