30-Second Stories • Native Audio • Multimodal References • Precise Control
Seedance 2.5 AI Video Generator
Seedance 2.5 is ByteDance Seed's next-generation audio-video model for creating synchronized clips up to 30 seconds. Turn text, images, video, and audio references into coherent stories with controlled camera work, timing, motion, and sound.
Seedance 2.5 Features
Seedance 2.5 moves beyond isolated clips toward complete audio-video storytelling, combining longer generation, flexible references, precise direction, and reliable visual continuity.
30-Second Audio-Video Generation
Create synchronized audio-video clips up to 30 seconds in a single Seedance 2.5 generation. Develop a fuller scene, performance, or story beat without stitching together a series of short fragments.
One-Take Storytelling
Direct continuous shots and longer narrative sequences with planned actions, camera movement, and pacing. Seedance 2.5 keeps subjects and scenes more stable as the story unfolds.
Flexible Multimodal References
Combine text, images, video clips, and audio files to define characters, props, composition, motion, visual style, and sound. The workspace supports reference-guided creation alongside text-to-video and frame-based workflows.
Smarter Reference Understanding
Seedance 2.5 interprets the intent, framing, camera language, and motion in reference footage instead of simply copying movement, giving you more useful creative control over the result.
Timestamp-Level Direction
Write time-based instructions such as 0–5s or 5–10s to control when actions, camera changes, dialogue, and scene transitions happen. This makes complex prompts easier to plan and refine.
Smoother Motion and Transitions
Generate more natural movement, steadier subjects, and smoother transitions between camera moves and scene changes. Seedance 2.5 is designed to preserve continuity across a longer sequence.
Synchronized Native Audio
Generate sound together with the visuals so dialogue, ambience, effects, and movement feel connected. You can also add audio references when a specific rhythm or sound direction matters.
Production-Focused Creative Control
Plan camera perspective, performance blocking, lighting, composition, and green-screen-style scenes through detailed prompts and references for ads, films, education, product demos, and previsualization.
How to Use Seedance 2.5
Create a synchronized, reference-guided Seedance 2.5 video in three steps.
Choose a Creation Mode
Start with text, a first frame, first and last frames, or multimodal references. Select Seedance 2.5, then choose the aspect ratio, 480p or 720p resolution, and a duration up to 30 seconds.
Direct the Story and Add References
Describe the subject, action, camera, lighting, sound, and mood. Add images, video, or audio references, and use timestamp ranges when you need precise control over the sequence.
Generate, Review, and Refine
Generate the synchronized video, review its timing and continuity, then adjust the prompt, references, duration, or framing before downloading the final MP4.
