Direct answer
Plan Seedance 2.5 as a sequence of timed beats: establish the scene, develop an action, introduce a turn and resolve it. Map every reference to a specific job.
For a 30-second concept, write four to six beats with approximate timestamps. Name the subject, camera position, action, transition and audio cue for each beat, then use references only where they reduce ambiguity.
This page answers the search question “how to use seedance 2.5” with current, source-linked information and a practical check you can repeat.
What the official pages establish
- seed.bytedance.com: ByteDance's Seedance 2.5 announcement documents up to 30 seconds per generation, larger multimodal reference sets, multi-round extension and timestamp-level editing. It also notes that availability rolls out by platform.
- yeha.ai: yeha.ai currently lists Seedance 2.5, Seedance 2.0 and Seedance 2.0 Fast in its video workspace. The selected model and settings determine the credit quote shown before generation.
How to make the decision
Use the longer window for a complete arc, not simply a longer static shot. Review transitions, character continuity, object placement and audio timing separately.
A useful rule: Treat a model announcement, a platform listing and access in your own account as three separate checks. The account screen and pre-generation quote are the final operational evidence.
Practical next steps
- Confirm the exact model version in the selector.
- Review duration, resolution, references and audio options before generating.
- Read the displayed credit quote before submitting the job.
- Keep the prompt, inputs and settings so a result can be reproduced or diagnosed.
Open the yeha.ai creative workspace and check the current video model selector. If pricing determines the decision, read the current pricing page before submitting a generation.
What to avoid
Do not assume that adding more references automatically improves consistency; contradictory references can weaken direction.
