Can I control what happens at a specific second?

Yes. Write the prompt in time ranges, for example 0–4s and 4–10s, and describe the action, camera and sound for each range.

How many references can one generation use?

Up to 30 images, 10 video clips and 10 audio clips.

Should I use Seedance 2.5 or 2.0?

Choose 2.5 for scenes longer than 15 seconds or with many references. Choose 2.0 when a shorter clip needs to be delivered in 4K.

What you can make with the Seedance 2.5 tool

These are the jobs people actually bring to Seedance 2.5, and the settings each one needs.

Complete short stories

Thirty seconds is enough for a setup, a turn and a payoff, generated as one continuous piece instead of stitched clips.

Previs from blockouts

Block a scene with simple 3D shapes, then use the render as the camera and staging reference and an image for the final look.

Reshooting green-screen plates

Keep the performance from a green-screen take and generate new backgrounds, props and supporting characters around it.

What Seedance 2.5 adds

These are ByteDance Seed's own Seedance 2.5 examples, cut to ten seconds each. Every one shows something Seedance 2.0 could not do in a single generation.

Official example · ByteDance Seed

One continuous 30-second take

A single tracking shot can run through a whole scene, with subjects, light and sound staying consistent from start to end.

Official example · ByteDance Seed

Dozens of references in one brief

Venue, performers, costumes and instruments can each come from their own image, and a crowded scene still keeps every one of them.

Official example · ByteDance Seed

Camera and blocking from a clay render

A rough grey-model animation fixes camera path, pacing and positions, while a separate image sets materials, color and mood.

Official example · ByteDance Seed

Edits you can aim

Green-screen replacement, camera-move changes and edits tied to timestamps let you change one part of a clip and keep the rest.
