How to Use Seedance 2.5 on Xelta.ai: A Step-by-Step Guide
Seedance 2.5 is now available on Xelta.ai as part of the platform's wider creative intelligence ecosystem, joining a growing set of image, video, and audio models that live inside a single workspace. For anyone who has not used a prompt-to-video model before, the idea of turning a short text description into a moving clip can feel abstract until you have actually done it once.
This guide walks through the process from start to finish: what to prepare before you open the tool, how to write a prompt that actually holds together as a video, a step-by-step first-generation workflow, how to review what comes back, and how to turn one approved clip into a small set of variations for a real campaign.
The best mindset going in is to treat your first generation as a draft, not a final asset. AI video models respond well to iteration, and most usable clips come from adjusting a prompt two or three times rather than getting everything right on the first attempt.
What to Prepare Before You Open Seedance 2.5
A little preparation before you start generating saves a lot of back and forth later. Three things are worth having ready.
First, gather any reference images you plan to use. If you want the output to match a specific character, product, or visual style, having clean reference images on hand means you can attach them from the first attempt instead of trying to describe the look purely in words.
Second, write a short brief for yourself, even if it is only a few lines. What is this clip for, what should happen in it, and what feeling should it leave the viewer with. A brief like this keeps you from writing a vague prompt and then trying to fix a vague result.
Third, decide on your target platform and format before you generate anything. A vertical clip for social stories needs a different aspect ratio, pacing, and duration than a horizontal clip for a landing page or a wide-format ad. Knowing the destination in advance means you are not reformatting or regenerating later.
How to Structure a Strong Prompt for Video
A strong video prompt is built the same way a shot description would be written for a film crew. Instead of one long descriptive sentence, break it into parts and cover each one:
- Subject: who or what is the focus of the shot. Be specific about appearance if it matters to the result.
- Action: what is the subject doing, and how does that action unfold over the length of the clip.
- Camera movement: is the camera static, panning, tracking the subject, or slowly pushing in. Naming this explicitly gives the model direction instead of leaving it to guess.
- Setting: where the scene takes place, including relevant background detail.
- Mood and lighting: the tone you want, such as calm and soft-lit, energetic and high-contrast, or clean and commercial.
- Duration and pacing: how long the clip should run and whether the action should feel quick or slow.
Writing each of these as a short, clear phrase rather than one dense sentence makes it easier to spot which part of the prompt to adjust if the output does not match what you intended.
Step-by-Step: Your First Generation on Seedance 2.5
Once your brief and any reference images are ready, the actual generation workflow follows a predictable sequence.
- Open Xelta.ai and select Seedance 2.5 from the available video models.
- If you are working from reference images, attach them to ground the subject or style before you write your prompt.
- Write your structured prompt covering subject, action, camera movement, setting, mood, and duration, as outlined above.
- Set your output format to match your target platform, such as vertical for social or horizontal for a broader placement.
- Confirm current plan limits and credits before starting a generation, especially if you plan to run several attempts or a larger batch later.
- Generate the clip and wait for it to render.
- Review the output against your original brief rather than judging it in isolation.
Treat this first result as a working draft. It is normal for the first pass to get the overall scene right while missing a detail in motion, timing, or framing, and that is exactly what the review step is for.
How to Review and Iterate on Your Output
Before approving a clip or moving on to variations, watch it through more than once with a specific checklist in mind rather than a general impression.
Check motion consistency first. Does the movement described in your prompt happen smoothly across the clip, or does it stall, jump, or reset partway through. Next, look for subject drift, meaning changes to a character's face, proportions, or key details as the clip progresses. This matters most when you are using reference images and need the subject to stay recognizable throughout. Finally, scan for unwanted artifacts such as warped hands, blended background elements, or objects that flicker in and out.
If something is off, go back to the specific part of your prompt tied to that issue rather than rewriting the whole thing. If the camera movement was wrong, adjust only that phrase. If the mood did not land, adjust the lighting and tone description. Small, targeted edits get you to an approved clip faster than starting over each time, and they make it easier to understand what actually changed the result.
Turning One Approved Clip Into a Campaign-Ready Set
Once you have a clip that matches your brief, the next step for most marketers and agencies is turning it into a small set of variations rather than treating it as a single, one-off asset.
Start from the approved prompt and change one variable at a time. That might mean generating the same scene in a different aspect ratio for a second platform, trying an alternate camera movement to see which performs better, or swapping the mood and lighting to test a different emotional tone against the same core action. Keeping the subject and setting consistent while varying one element at a time makes it easy to compare results side by side and understand which change actually improved the clip.
Before generating a full batch of variations, confirm current plan limits and credits so you can plan how many versions to run without interruption. Once you have your set, review each variation against the same checklist used for the original clip, motion consistency, subject drift, and artifacts, before exporting anything for use in a live campaign.
