Seedance 2.5 Prompt Guide for Best AI Video Results

Seedance 2.5 is one of the most capable AI models coming to OpenArt’s AI video generator, and a lot of what makes it powerful comes down to how you prompt it. The 50-reference system, the 30-second native output, region editing, and knowing how to use these well makes a real difference in what you get out of each generation.

This guide covers what actually works best.

Describe the scene, not just the subject

“A woman walking down a city street.” That is a fine starting point, but it leaves a lot up to the model.

Seedance 2.5 responds much better when you describe the full scene: what the subject is doing, what the environment looks like, and how the camera is moving. “A woman in a red coat walking down a rainy city street at night, slow tracking shot from the side, shallow depth of field, streetlights reflected in the puddles.” Same subject, completely different result. The more context you give, the less the model has to guess.

Use references instead of describing appearances

This is the biggest shift Seedance 2.5 makes possible. When you have 50 reference slots, you do not need to spend half your prompt describing what someone looks like.

Upload a reference image of the character and let the model anchor to it. Same with products, environments, and visual styles. If you have a video that captures the mood or colour palette you want, add that as a style reference. The model uses these inputs to hold visual consistency across the full 30-second clip in a way that text alone cannot guarantee.

A good rule: if you can show it, do not just describe it. Reserve your prompt text for what the reference cannot tell the model, like the action, the camera move, and the pacing.

Mix your reference types

The 50-input system accepts images, video clips, audio files, and 3D meshes. The most effective generations usually combine more than one type.

For a brand film, that might mean a product image for the subject, a short video clip for the visual style, and an audio file for the sound direction. Each reference type controls a different dimension of the output. Character images hold faces. Style clips govern the overall look and feel. Audio references shape the soundscape. When you combine them, you are giving Seedance 2.5 directorial-level inputs rather than a single text description.

Structure your 30 seconds as a real scene

Seedance 2.5 holds a full scene arc across 30 seconds in one generation. That means your prompt can, and should, describe what happens across that time rather than a single frozen moment.

Think in three beats. What is happening at the start? What develops in the middle? What is the final frame? Something like: “Opens on a product on a white surface, slow push-in, light shifts from cool to warm as the camera closes in, final frame on the label in sharp focus.” That gives the model a beginning, a movement, and an end, and it will follow that structure more reliably than a static description.

Direct the camera explicitly

Seedance 2.5 reads camera direction from your prompt. If you want a specific shot, name it.

Words like “tracking shot,” “slow push-in,” “wide establishing shot,” “handheld,” “aerial,” “dolly forward,” and “rack focus” all work. Do not assume the model will choose the right camera move if you do not specify one. Camera direction is one of the easiest things to control in your prompt, so it is worth being explicit every time.

Use region editing when something small is wrong

Region editing is there for the situation where 90% of your clip is right and one element is not. Before you regenerate the full clip, check whether the issue is isolated to a specific area.

A product label that came out slightly wrong, a face angle that did not land, a background detail that does not fit. Region editing lets you target only that part and re-render it without touching the rest. This saves generations and preserves everything in the clip that was already working.

Include audio direction and dialogue in your prompt

Because Seedance 2.5 generates audio in the same pass as the video, you can shape the sound directly through your prompt. Describe the acoustic environment: “quiet indoor space,” “busy street with traffic noise,” “dramatic score building to the final frame.”

If you have an audio reference file, add it to your reference pool for more precise control. But even without one, mentioning the sound environment in your prompt will produce better audio than leaving it unspecified.

3 Sample Prompts

Here is how all of these guidelines come together in practice.

Sample 1: Product Brand Film

Mode: Text to Video References: product image + brand style video clip

A skincare serum bottle sits on a white marble surface with soft natural light coming in from the left. Opens on a wide shot. Slow push-in over the first ten seconds as the light gradually warms. A hand enters frame from the right at the midpoint and picks up the bottle, turning it slowly. Final frame is a tight close-up on the label with the background soft and blurred. Quiet indoor atmosphere, subtle ambient tone.

What this demonstrates: a clear three-beat scene arc (establishing, reveal, close), explicit camera direction, audio direction, and references that handle the visual look without needing text description.

Sample 2: Multi-Character Scene

Mode: Reference Generation References: character A image + character B image + cafe environment image + style video clip

Two people sit across from each other at a small cafe table in late afternoon light. Opens on a wide shot of the cafe interior with warm window light filling the space. Cuts to a medium two-shot of both characters at the table. The person on the left picks up a coffee cup and speaks. The person on the right leans forward in response. Handheld camera with slight natural movement throughout. Warm ambient cafe noise, soft background chatter.

What this demonstrates: character reference images doing the heavy lifting on appearances, leaving the prompt to handle action, camera style, and audio. An environment reference anchors the location without a long text description.

Sample 3: Cinematic Landscape

Mode: Image to Video References: landscape image + cinematic style video clip

A lone figure stands at the edge of a cliff at golden hour, ocean stretching ahead. Begins as a wide aerial shot from high above and behind the figure. Camera descends slowly over the first fifteen seconds, moving toward eye level. Holds at a medium distance behind the figure at the midpoint. Final frame is a wide shot with the full ocean horizon visible. Wind sound, distant waves, orchestral score building gradually toward the end.

What this demonstrates: a full 30-second camera arc described as a single movement, audio woven into the prompt naturally, and an image reference that sets the starting frame so the prompt can focus on what changes.

Start with a clear scene description, layer in references for anything visual you can show rather than describe, and structure your prompt across the full 30 seconds. Seedance 2.5 rewards specificity, and the more direction you give it, the more precisely it delivers what you had in mind.
