Create Complete Stories, Not Just Short Clips
Seedance 2.5 is a next-generation joint audio-video model designed to turn creative briefs into more complete video sequences.
Instead of extending one simple moment, the model can organize connected shots into a structured narrative with an introduction, development, transition, and conclusion. A single generation can last up to 30 seconds, while video extension helps creators continue the story across longer sequences.
Use Seedance 2.5 when your idea requires more than an isolated camera movement. Build campaign films, product stories, fashion sequences, performance videos, short narratives, and cinematic concepts with greater continuity from shot to shot.

Key Features of the Seedance 2.5 AI Video Generator
30-Second Generation with Multi-Round Extension
Generate synchronized audio-video sequences up to 30 seconds in a single pass, connecting multiple shots into a complete narrative with a clear opening, progression, transition, and ending. Then continue the story through multiple extension rounds that maintain the main characters, environment, visual language, sound, and narrative pacing.
Multimodal Reference & Motion Control
Combine up to 30 images, 10 videos, and 10 audio clips in one creative brief. Use references to guide characters, products, environments, styling, lighting, music, and sound effects — and transfer the movement, framing, pacing, performance, and camera language of reference footage to new subjects, scenes, or visual styles.
Consistent Characters and Scenes
Keep recognizable characters, props, environments, and visual styles across changing actions and camera angles. Seedance 2.5 improves stability in multi-character scenes and complex sequences with multiple shot transitions.
Timeline-Based Prompting
Define what happens during specific moments of the video. Timeline instructions give you greater control over shot order, character actions, camera movement, pacing, transitions, and narrative development.
Precise Video Editing
Make targeted changes to characters, actions, plot elements, audio, or camera perspectives using timestamp-level instructions. Seedance 2.5 also supports reference-based editing, green-screen editing, and camera perspective adjustments.
Joint Audio-Video Generation
Generate visuals and synchronized audio as one coordinated result. Seedance 2.5 can align vocals, music, environmental ambience, and sound effects with the actions, timing, and atmosphere of each scene.

Alih-alih menulis
Create a cinematic product video.
Tulis
Create a 30-second cinematic product film for the electric shaver shown in Image 1. Begin with a macro close-up of the matte-black surface under a narrow overhead light. Slowly rotate around the product as water droplets move across the metal. At 10 seconds, transition into a modern bathroom and show the product being used. Follow the controlled camera movement in Video 1. Use restrained electronic sound design with the rhythm of Audio 1. End with the shaver standing upright on a dark reflective surface in a clean hero composition.
Seedance 2.5 Prompt Examples
Cinematic Product Commercial
Create a 30-second cinematic commercial for the running shoe shown in Image 1. 0–6 seconds: Begin with an extreme close-up of the sole touching wet asphalt at night. Show realistic water displacement and material detail. 7–15 seconds: Track the athlete from the side as they run through a neon-lit city street. Follow the camera rhythm and body movement from Video 1. 16–24 seconds: Transition into a wide shot as the athlete crosses an empty bridge before sunrise. 25–30 seconds: End with the shoe on a concrete platform, using the lighting and composition from Image 2. Add restrained impact sounds, footsteps, city ambience, and a final low-frequency brand hit.
Fashion Editorial Film
Generate a 30-second editorial fashion sequence featuring the model from Image 1 wearing the outfit from Image 2. Use the architectural environment from Image 3 and the slow, controlled camera movement from Video 1. Begin with a close-up of the fabric moving in the wind. Pull back as the model walks through the space. Transition between front, profile, and wide architectural shots while preserving the model’s appearance and clothing details. Use minimal ambient music based on Audio 1. End with the model stopping beneath a sharp beam of natural light.
Branded Short Story
Create a 30-second narrative film about a young designer preparing for an important presentation. 0–8 seconds: Show the designer working alone in a dim studio at night, surrounded by sketches and prototypes. 9–18 seconds: Follow the designer through a quiet city as morning begins. Maintain the character from Image 1 and use Image 2 for the city’s visual style. 19–26 seconds: The designer enters a bright presentation room and places the final prototype on the table. 27–30 seconds: End with a close-up of the designer’s relieved expression as the room becomes silent. Use subtle room ambience, footsteps, paper sounds, and restrained emotional music.

Tips for Better Seedance 2.5 Results
Give Every Reference a Purpose
Do not upload a large group of unexplained assets. State exactly what the model should take from each image, video, or audio file.
Write Actions in Sequence
Describe actions in the order they should occur. For complex videos, divide the prompt into time ranges.
Separate Identity from Style
Use one reference for the subject and another for the visual style when possible. This helps the model understand what must remain consistent and what should influence the presentation.
Describe Camera Movement Precisely
Replace vague instructions like “cinematic camera” with specific movements such as a slow dolly in, handheld tracking shot, low-angle orbit, macro push-in, crane shot, or locked-off wide shot.
