seedance-2.5/image-to-video

Key Features

• Native 30-second clips — up to 6x the duration ceiling of Seedance 2.0, with room for multi-beat scenes in a single generation.
• Up to 50 full-modal reference assets — the richest reference budget in the Seedance family for complex multi-character, multi-scene compositions.
• Image-faithful generation — preserves the reference image's subject identity, composition and lighting while animating it into natural motion.
• Native audio-visual synchronization — generates video with synchronized audio in a single pass (enabled by default).
• Sharper editing and generation control — ByteDance's next-generation Seed architecture improves precision over Seedance 2.0 in both prompt adherence and reference fidelity.
• Director-level control over camera movement, lighting, shadows and character performance through prompts.

Parameters

2. Write your prompt — describe the scene with cinematic detail: action, camera movement, lighting, mood.
3. Set duration — choose any duration from 4 to 30 seconds.
4. Run — submit and download your cinematic video with synchronized audio.
