How to Create an AI Video on Seedance2Video: A Beginner's Step-by-Step Guide
Creating a useful AI video does not begin with a long prompt. It begins with one clear job for the clip, the right model for that job, and a small first test you can improve.
On Seedance2Video, the basic workflow is: describe the shot, select a model, choose the aspect ratio, resolution and duration, then generate. This guide walks through every choice—from a blank prompt box to a first video you can review and refine.
Quick answer: For a first attempt, start with one 8-second shot at 720p. Choose Lite for a simple, high-value test; Fast when you need to iterate quickly; Mini when you need many economical variations; and Pro when the brief needs higher visual quality or real human faces. Write one subject, one action, one setting and one camera instruction. Generate once, then change only the weakest variable on the next run.

What you need before you generate
You only need a small creative brief. Write down these four choices before opening the generator:
| Decision | Example | Why it matters |
|---|---|---|
| Goal | A short product reveal for a landing page | Keeps the clip focused instead of asking for a whole campaign in one generation |
| Main subject | A glass skincare bottle | Gives the video one visual anchor |
| One action | The bottle slowly rotates into the light | Gives the model a clear motion to create |
| Destination | A 9:16 social post or 16:9 website video | Determines the frame you should start with |
If your goal is to animate an existing product photo, character or scene, begin with image to video. If you want the model to invent the scene from a written description, begin with text to video.
The first version should be a single shot, not a full story. A clean 8-second test reveals whether the subject, motion and visual direction are working before you invest in more elaborate prompts.
Understand the Seedance2Video generator
The home-page generator has five choices in one row: prompt, model, aspect ratio, clarity and duration. You do not need to perfect all five at once.
What each control does:
| Control | What to decide | Good beginner default |
|---|---|---|
| Prompt | What is in the shot and what changes | One subject + one action + one visual direction |
| Model | Whether quality, speed or efficiency is your priority | Lite for a small first test |
| Aspect ratio | Where the clip will be watched | 16:9 for a site or YouTube; 9:16 for vertical social video |
| Clarity | How much output resolution you need for the test | 720p first; use 1080p after the idea works |
| Seconds | How much motion must happen in one clip | 8 seconds for one deliberate shot |
The interface may evolve, so use the live settings available in your account as the final source of truth. The workflow stays the same: keep the first render small and purposeful, then increase quality or duration only after the concept is right.
Choose the right Seedance model
Model selection is a production choice, not a quality ranking. The right option depends on whether you are testing an idea, producing many variants, or polishing an important shot.
Seedance model selection guide
| Model in the generator | Choose it when | Practical first use | What the interface emphasizes |
|---|---|---|---|
| Seedance 2.0 Lite | You need a straightforward first draft with supported 8-second output | Test a single text-to-video concept at 720p | High value; 8-second videos in 720p or 1080p |
| Seedance 2.0 Pro | The brief prioritizes visual quality or includes real human faces | A hero product moment, creator-style shot or client-facing concept | High quality; supports real human faces |
| Seedance 2.0 Fast | You expect to make several prompt revisions and speed matters | Try three camera or action variants before committing | Lower cost and faster generation |
| Seedance 2.0 Mini | You need cost-conscious exploration or a larger set of variations | Explore hook ideas, backgrounds or simple motion directions | Exceptional cost performance |
| Seedance 1.5 Pro | You need a dependable everyday starting point | Simple routine production where the brief is already clear | Daily workhorse; best value |
A simple decision rule:
- Choose Lite when you are learning the controls or validating one idea.
- Choose Fast when the next decision depends on trying variations quickly.
- Choose Mini when you need a wider pool of lower-cost options to review.
- Choose Pro when the selected shot matters enough to prioritize quality or human-face support.
- Choose 1.5 Pro when you already know the type of everyday output you need and want a practical workhorse.
These descriptions reflect the labels shown in the current model selector. Availability, output settings and credit cost can change, so check the live menu before a production run.
Set the aspect ratio, resolution and duration
The best settings are the smallest settings that can answer your creative question. Do not begin by asking the model to solve every production constraint at maximum resolution.
Pick an aspect ratio based on where the video will go
| Use case | Start with | Why |
|---|---|---|
| Website hero, product page, YouTube or presentation | 16:9 | Wide composition gives room for a subject, environment and camera movement |
| Reels, Shorts, TikTok or vertical paid social | 9:16 | Fills a phone screen and keeps the subject prominent |
| Square feed post or compact catalogue placement | 1:1 | Keeps a centered subject readable in a square layout |
Start at 720p and 8 seconds
For a first render, 720p and 8 seconds are a useful working default. At this stage, you are testing the direction: Does the subject look right? Does the motion feel intentional? Does the composition serve the channel?
Move to 1080p only when that test passes and you need a higher-resolution version. Keep the duration short when the action is simple. If you need a story with multiple beats, generate separate shots and edit them together rather than packing a full sequence into one overloaded request.
Write a prompt that gives the model a clear shot
A beginner prompt does not need poetic language. It needs clear priorities. Use this structure:
Subject + setting + action + camera + lighting/style + ending frame
Example: product video prompt
A clear glass skincare bottle on a stone pedestal in a bright editorial studio.
The bottle slowly rotates clockwise as a narrow beam of warm light moves across the label.
Slow push-in camera, clean premium product-film style, soft shadows, neutral background.
End on a centered close-up with the label fully visible.
Why this works:
| Prompt element | What it controls |
|---|---|
| Clear glass skincare bottle | Keeps the main subject specific |
| Stone pedestal and studio | Establishes the setting without introducing a second storyline |
| Slowly rotates | Gives the clip one visible action |
| Slow push-in | Sets a deliberate camera direction |
| Warm light, soft shadows | Establishes a consistent visual mood |
| Centered close-up | Tells the model where the shot should land |
For more reusable prompt structures, read the AI video prompt formula for Seedance 2.5 and use the Seedance 2.5 prompt examples as starting points—not copy-and-paste rules.
Keep the first prompt narrow
Avoid combining too many competing instructions in a first render:
- Two locations
- Multiple unrelated characters
- A sequence of four camera moves
- Exact on-screen copy plus complex action
- A complete story arc in eight seconds
Start with one shot. If the subject works but the shot is too static, change only the action or camera instruction. If the motion works but the look is off, change only lighting, environment or style. This one-variable method makes results easier to diagnose.
Generate, review and improve the next version
When the prompt, model and settings are selected, choose Generate Video. Treat the first output as a test, not a finished asset.
Review the first clip with four questions
| Review question | If the answer is no | Change next |
|---|---|---|
| Is the main subject recognizable? | The subject drifted or is too vague | Make the subject and materials more specific; add a reference image if needed |
| Does one clear action happen? | Motion is weak, confusing or overbusy | State one action and simplify competing verbs |
| Does the camera serve the clip? | The framing feels accidental | Add one camera direction such as slow push-in, orbit or tracking shot |
| Does the result fit the destination? | The composition does not work for the channel | Change the aspect ratio or reserve more room around the subject |
Then create a second version by changing one variable. For example, keep the prompt and settings the same but change Lite to Fast for a set of quick variations; or keep the model the same but replace “dynamic camera movement” with “slow push-in camera.”
If you hit prompt drift, awkward motion or a character inconsistency problem, use the Seedance 2.5 prompt troubleshooting guide before making the prompt longer.
Use an image when you need more control
Text is excellent for exploring an idea. A reference image is better when you need to preserve a particular product, composition, character, packaging detail or art direction.
Use image to video when the still image already contains the visual identity you want. Your prompt should then focus on what changes over time:
Preserve the product shape, label and centered composition from the reference image.
Add a gentle left-to-right camera orbit and a soft highlight moving across the glass.
Keep the background minimal and the product in sharp focus.
This makes the reference responsible for identity and layout, while the prompt is responsible for motion, camera and atmosphere. See the Seedance 2.5 image-to-video workflow for a repeatable product-video process.
A first-video workflow you can repeat
- Decide whether you need a text-to-video idea or an image-to-video animation.
- Define one subject, one action and one destination channel.
- Select a model based on the work: Lite for a first test, Fast for iteration, Mini for economical variation, Pro for quality-sensitive or real-human-face work.
- Start with the right ratio, 720p and an 8-second single shot.
- Write the prompt as subject + setting + action + camera + lighting/style + ending frame.
- Generate the first version.
- Review the subject, action, camera and channel fit.
- Change one variable and generate the next version.

FAQ
Which Seedance model should a beginner choose?
Start with Seedance 2.0 Lite for a small, straightforward 8-second test. Move to Fast when iteration speed matters, Mini when you need economical exploration, and Pro when the shot prioritizes visual quality or real human faces.
Should I use text to video or image to video?
Use text to video when you are exploring a concept from words. Use image to video when you already have a product image, character, composition or visual style that must remain recognizable.
What settings should I use for my first AI video?
Start with the aspect ratio your channel needs, 720p and an 8-second single shot. This gives you a quick way to evaluate the concept before committing to a higher-resolution output or longer sequence.
Why did my first result not match the prompt exactly?
AI video improves when instructions have clear priorities. Reduce the number of actions, locations and style directions, then change one variable at a time. A reference image can help when the exact subject or composition matters.
Can I create a complete video in one generation?
For short clips, start with one shot. For a larger story, generate individual shots for each beat and edit the strongest versions together. This is usually easier to review and control than one overloaded prompt.
Create your first video, then improve the workflow
Open the Seedance AI video generator, create one focused first shot, and use its result to decide what to improve next. When you are ready for stronger prompt control, continue with the AI video prompt formula, camera movement prompts, and Seedance 2.5 workflow guide.
