Refer to every input in the prompt with an @ tag: @image1, @video1, @audio1, and so on. The tags must be written exactly like that, including the @ symbol and without spaces — plain text such as image1 is treated as ordinary words, not a reference.

How to Use Seedance 2.5

Seedance 2.5 turns a structured brief and optional text, image, video, and audio references into a longer, more controllable audiovisual scene.

1

Define the Story Goal

Choose a focused use case such as a product reveal, narrative scene, social ad, storyboard, or character performance before adding Seedance 2.5 references.

2

Upload and Label References

Add relevant images, video clips, audio, or other supported assets, then state which reference controls each character, product, location, motion, style, or sound.

3

Write a Timed Video Brief

Describe the shot order, subject actions, camera movement, lighting, dialogue, sound cues, and final frame so Seedance 2.5 can follow the intended sequence.

4

Generate, Inspect, and Edit

Create the video, check identity, motion, framing, text, and audio across the full timeline, then make a targeted edit or simplify conflicting instructions.

Common Problems With Longer AI Video

Longer AI video scenes can drift when character identity, product details, camera logic, audio, and dozens of creative references are not coordinated in one brief.

Short Clips Require Stitching
Building a complete ad or story beat from several small generations can introduce visible jumps in identity, lighting, motion, and sound.
Large Reference Sets Conflict
Characters, products, locations, storyboards, motion examples, and audio cues can compete when their roles are not explicitly assigned.
One Error Forces a Rerender
A wrong prop, costume, hand pose, or background detail should not require discarding an otherwise useful sequence.

Seedance 2.5 Workflow for Controlled Video

Seedance 2.5 combines longer native generation, expanded multimodal reference capacity, and controllable editing to reduce stitching and repeated full-scene renders.

Outline the opening, development, payoff, and final frame before generating so a longer clip has a readable narrative arc.

Group assets by identity, product, environment, storyboard, movement, camera, style, dialogue, and sound, then cite each role in the prompt.

Specify shot timing, physical interaction, camera paths, dialogue, effects, and music cues as one audiovisual sequence.

Use supported secondary editing controls to correct a selected subject, prop, outfit, or background while preserving the useful composition and timeline.
