About
A scene may draw its character, object and setting from different images. Seedance 2.5 reference to video supports a larger reference set than the other current video models: its model configuration allows up to 30 images. Give every reference a clear job, then describe a focused scene rather than asking the model to combine everything indiscriminately. Choose 4–30 seconds, output through 1080p and optional audio. Use a start-frame or two-frame workflow when the opening or ending needs a particular supplied composition.
Questions
How many references does Seedance 2.5 support?
The current model configuration supports up to 30 image references. Start with a smaller, clearly explained set when it covers the subject and scene; adding images without a role makes the intended direction harder to describe.
Should the references include my first frame?
A reference supplies visual guidance. If an image must be the opening composition, use Image to Video. Use First & Last Frame when both endpoints need supplied images.
How do I describe several references?
Identify which image shows the subject, which establishes the setting and which contributes a visual treatment. State the important features, then describe the action, camera and pace of the new shot.
Can I combine a longer duration with sound?
Seedance 2.5 supports 4–30 seconds and an audio switch. Describe relevant sounds when audio is enabled, then review both sound and visual continuity in the result.
Will a larger reference set guarantee consistency?
Check faces, costumes, proportions and identifying details across the clip. Reference capacity describes supported inputs, not perfect preservation or a measured advantage for a particular scene.
