STORY DEVELOPMENT & EXTENSION
Sunflower Skateboard Story
Extend video with warm afternoon slice-of-life narrative.
PROMPT
Extend forward by 10s. In warm afternoon light, camera starts from the row of awnings fluttering in the breeze at the street corner, slowly moves down to a few small daisies poking out at the base of the wall. Then the protagonist's red skateboard shoes appear in the frame. He is crouching in front of a street flower stand, smiling and gathering a large bunch of sunflowers into his arms, petals brushing against his white T-shirt. As he turns to step on the skateboard, the flower stand owner laughingly shouts 'Watch out for flying petals!' He waves at the owner, then starts skating. A few golden petals have already broken free from the bouquet first, falling onto the skateboard deck.

FAQ
What's new in Seedance 2.0 compared to previous versions?
Seedance 2.0 is a major upgrade from ByteDance's Jimeng AI. It supports true multimodal input — combining images (up to 9), videos (up to 3, total 2-15s), audio (up to 3, total up to 15s), and text in a single generation. Key improvements include more realistic physics, smoother motion, more precise instruction following, and more stable style consistency. It also features built-in sound effects and background music generation.
How does the @reference system work?
After uploading your materials, reference them in your prompt using @materialName to specify each asset's role. For example: '@image1 as first frame, @video1 reference camera movement and action, @audio1 for background music rhythm'. You can reference anything — actions, effects, styles, camera angles, characters, scenes, and sounds. The total number of uploaded files is limited to 12 across all modalities.
What are the key capabilities of Seedance 2.0?
Seedance 2.0 excels in: (1) Character and scene consistency — faces, clothing, and details remain stable across frames; (2) Precise camera movement replication from reference videos; (3) Creative template and VFX reproduction — transitions, ad formats, film segments; (4) Video extension — seamlessly extend existing videos up to 15s; (5) Video editing — replace characters, modify scenes, adjust actions in existing videos; (6) Audio-synced generation — beat-matching, voice acting, and music-driven visuals; (7) One-take long shots with coherent continuity.
What file formats and sizes are supported?
Images: jpeg, png, webp, bmp, tiff, gif (up to 9 files, each under 30MB). Videos: mp4, mov (up to 3 files, total duration 2-15s, each under 50MB, resolution between 480p and 720p). Audio: mp3, wav (up to 3 files, total duration up to 15s, each under 15MB). Generated video duration is customizable from 4 to 15 seconds.
What's the difference between All Reference and First & Last Frame modes?
All Reference mode supports full multimodal input (images, videos, audio, text) with the @reference system for maximum creative control. First & Last Frame mode is optimized for image-to-video generation where you only need to upload starting and ending frames. If you only upload a first frame image + prompt, you can use either mode; for multi-modal combinations, use All Reference mode.
Are there any content restrictions?
Due to platform compliance requirements, uploading materials containing realistic human faces (both photos and videos) is currently not supported. The system will automatically block such materials. This applies to both reference images and reference videos. Animated, illustrated, or stylized characters are not affected by this restriction.
