Seedance 2.5 Prompting: A Practical Guide to Better AI Videos

Writing an effective Seedance 2.5 prompt focuses on providing the model with a clear sequence of instructions rather than merely using adjectives. Consider a woman drinking coffee in a Paris café, which sounds fine but leaves too much to the model's interpretation. For instance, should she pick up the cup, look at the camera, move the camera, speak, or how long should each action take?

Shorter clips may have less ambiguity, but longer videos with camera movements, dialogue, and reference assets can quickly become problematic.

Treat your Seedance 2.5 prompt more like a shot brief than an image description. The guide outlines a practical structure you can reuse, covering actions, timestamps, camera direction, and multimodal references. Begin by thinking in actions, not just images. Use a structure like Subject → Action → Environment → Camera → Visual Style.

For example, instead of stating "A woman drinking coffee in a Paris café, cinematic," provide a more structured prompt such as "A young woman sits beside a large window in a Paris café. She picks up a ceramic coffee cup with her right hand, takes a slow sip, places it back on the table, and looks out toward the street. Medium shot with a slow push-in.

Warm afternoon sunlight, natural skin tones, shallow depth of field, realistic cinematic photography."

Break down complex actions into smaller steps. Instead of saying "A basketball player performs a spin move and scores," describe the movement in sequence: "The basketball player dribbles toward the defender with his right hand. He plants his left foot, lowers his center of gravity, and rotates past the defender. He transfers the ball back to his right hand, takes two steps, jumps, and releases a right-handed layup. He lands and watches the ball enter the basket."

When the video contains multiple beats, use timestamps to organize the prompt. For longer videos, a template like "0–5s: 5–12s: 12–20s: 20–30s:" can be helpful. For example, in a product video, organize it as "0–5s: Wide shot of a matte black portable speaker on a wooden table in a modern living room during golden hour. 5–12s: The camera slowly pushes toward the speaker, revealing the grille texture and side controls.

12–20s: A hand enters the frame and presses the power button. Cut to a close-up of the indicator light turning on. 20–30s: Return to a polished three-quarter hero shot."

Be specific about camera direction using concrete camera instructions instead of vague terms like "cinematic." Examples include "wide shot," "medium shot," "close-up," "overhead shot," and "tracking shot." For example, "A chef places a finished dessert on a marble counter. Start with an overhead shot, then slowly push in toward the dessert as the chef adds the final garnish."

Lastly, assign a clear role to every reference input in Seedance 2.5. Use the principle "One Reference = One Job." For instance, @Image 1 defines the product's appearance, @Video 1 controls camera movement and pacing, and @Audio 1 specifies background music and overall rhythm.
