Latest ModelSeedance 2.5 Long Video Product Demonstration
Learn seedance 2.5 long video product demonstration with a source-grounded Seedance 2.5 workflow.
seedance 2.5 long video product demonstration starts with a product demonstration with a setting, use moment, and closing detail. Start with a written story outline, then give the sequence a visible order that a viewer can follow. Long Video mode supports a single video from 30 to 180 seconds.
Project focus
Treat a product demonstration with a setting, use moment, and closing detail as the decision that shapes this piece. Establish the main subject and setting before the first change, then describe the next visible action in plain language. Place camera direction beside the action it supports, so a close detail, wider reveal, or change of viewpoint arrives when the story needs it.
A maker can begin with the object on a workbench, show it in use, and end on a clean hero view. A skincare team can build around texture and daily ritual. A furniture studio can let a room change as the piece enters it.
A useful creation path
- Choose a duration that fits the story beat.
- Describe the setting, subject, action, and camera direction in story order.
- Review the finished sequence as one continuous piece.
Review the finished sequence
Read the project from the first image through the closing beat. The viewer should be able to identify the subject, setting, and purpose of every action. Keep the details that make a product demonstration with a setting, use moment, and closing detail useful, and let later shots develop from the decisions set in the opening section.
