Up to 30 Seconds of Continuous Storytelling

Expanded Multimodal References
Use text, images, video, and audio together to guide characters, style, action, camera movement, and sound pacing.
Controllable Video Editing
Change content and effects around an existing video while reducing the character and composition drift caused by regenerating from scratch.
Second-Level Scene Control
Describe shots, actions, and transitions by time range so every segment of a longer video has a clear job.
Audio-Visual Sync and Multilingual Expression
Place sound, dialogue, and visual rhythm in the same creative instruction for music videos, ads, and multilingual content.
Extension and Post-Production Effects
Extend clips, replace elements, and add visual effects so one asset can evolve through iteration instead of repeated restarts.

How to Write a Controllable 30-Second Prompt
Define one story line, assign a job to each time block, then add sound and continuity constraints.
Establish the Subject and Visual Rules
Introduce the character, product, or hero object, then use references to lock appearance, composition, and light.
Develop Action and Transitions
Describe how the camera moves, how scenes connect, and where music or dialogue changes.
Deliver the Climax and Close
Place the strongest visual action at the climax, then finish with a brand frame, emotional beat, or loop.
Four Prompt Structures for Seedance 2.5
Copy a template, replace the bracketed details, then add references and timing step by step.
Time-Blocked Brand Film
Create a 30-second [brand theme] film. 0–10s: [opening subject, environment, camera]; 10–20s: [action development, transition, audio cue]; 20–30s: [visual climax, brand close]. Keep the [character/product] appearance consistent, use one [color palette], and avoid background jumps or warped text.
Best for brand ads, product stories, and event teasers.
Multi-Asset Creation
Use [image reference] to lock the character and wardrobe, [video reference] for camera movement and action rhythm, and [audio reference] for edit beats. Generate a [duration] video in this order: [scene sequence]. Keep subject proportions, materials, and light direction consistent.
State what each material controls so references do not compete.
Localized Edit with Structure Preserved
Keep the source video's character, action, duration, camera movement, composition, and background unchanged. Replace only [target element] with [new element], and add [effect description]. Match the original lighting, perspective, occlusion, and motion blur.
Explicit preservation rules usually make edits more stable.
Timeline Action Design
0–3s: [establishing shot]; 3–8s: [action one]; 8–12s: [transition]; 12–18s: [action two]; 18–24s: [climax]; 24–30s: [ending]. For every block, specify shot size, camera direction, sound, and required continuity.
Blocks do not need equal length, but each needs a clear start and result.
