AI video generation is getting better incredibly fast. Just a year or two ago, creating a realistic video with the same character from one scene to another was a real headache. The face would change, the hairstyle would shift, the body type could suddenly look different, and the final result often felt unstable.
Today, tools like Seedance 2 make it much easier to generate cinematic AI videos with realistic people, smooth motion, and consistent character appearance. But there is still one common problem many users run into: generating videos with a real-looking face and keeping that face stable throughout the whole clip.
If you’ve tried to create AI videos using your own appearance, a model, an actor, a brand character, or another real person’s look, you probably know what I’m talking about. Some AI video generators limit the use of realistic faces, while others struggle to preserve identity from frame to frame.
In this article, I’ll show you a practical workflow for creating AI videos in Seedance 2 using a clear visual reference, while keeping the character’s appearance consistent across the video.
Why AI Video Generators Struggle with Real Faces
Before we get into the workflow, it’s useful to understand why this happens.
AI video models don’t “remember” a person the way humans do. When you upload one photo, the model tries to understand the face, hairstyle, proportions, skin tone, facial expression, and overall style from that single image. But one photo is often not enough.
For example, a front-facing portrait doesn’t show the side profile. A close-up doesn’t explain body proportions. A photo with sunglasses may hide important facial details. And if the lighting is too dramatic, the AI may misunderstand the actual face shape.
That’s why the result can become inconsistent. In one frame, the character may look accurate. In the next one, the nose, eyes, jawline, or hairstyle may slightly change. In longer AI videos, these small changes become even more noticeable.
The best way to improve face consistency is to give the AI a stronger visual reference.
Step 1: Create a Face Reference Collage
The first thing you need is a high-quality reference collage. This collage should include several images of the person or character from different angles and distances.
You can create this collage in Nano Banana Pro or GPT Image 2. The idea is simple: instead of giving Seedance 2 just one photo, you give it one image that contains multiple views of the same person.
I recommend using 3–5 photos as source references. Try to choose images that show the person clearly:
front view;
side profile;
three-quarter angle;
close-up portrait;
medium or full-body shot if needed.
The more useful visual information you provide, the easier it is for the AI to understand and preserve the person’s appearance.
*Here is the prompt you can use to generate the collage:
*
Create a collage with photos of this person from different angles, distances, and perspectives, showing them from every possible side. Keep all appearance details in the same style without any changes. All frames should preserve the same consistent look of the person.
Once the collage is ready, save the image. This will become your main reference file for AI video generation.
Why a Collage Works Better Than a Single Photo
A collage gives the AI model more context. Instead of guessing how the person looks from different angles, the model can “see” several versions of the same face in one reference image.
*This helps with:
*
- keeping the same facial features;
- preserving hairstyle and face shape;
- improving character consistency;
- reducing random changes between frames;
- generating more realistic close-ups;
- making the video look more natural.
If you want to create AI videos with a stable character identity, this step is extremely important. A good reference collage can make the difference between a random-looking AI clip and a polished cinematic video.
Step 2: Open Seedance 2 Through Syntx AI
For generating videos, I use the Syntx AI aggregator. It’s convenient because it includes more than 90 AI models for different creative tasks: image generation, text generation, video generation, audio tools, and more.
The main advantage is that you don’t need to buy separate subscriptions for every AI model. Everything is available in one place under one subscription. This is especially useful if you work with different formats and don’t want to jump between many platforms.
Inside Syntx AI, you can access Seedance 2.0, which is one of the tools used for generating realistic AI videos.
Seedance 2 is especially useful if your goal is to create videos with:
realistic people;
cinematic scenes;
consistent characters;
smooth movement;
dynamic camera angles;
detailed environments;
natural facial expressions.
Step 3: Upload Your Collage as a Reference
After you open Seedance 2 in Syntx AI, upload the collage you created earlier. This collage will work as the visual identity reference for the character.
When writing your prompt, mention the reference using @. This tells the model that the character in the video should follow the appearance from the uploaded image.
For example, your prompt may start like this:
Create a cinematic video of @reference walking through a modern city street at night...
Then continue describing the scene, action, lighting, camera movement, mood, and style.
Step 4: Write a Strong Prompt for Better Results
A good prompt is just as important as a good reference image. If your prompt is too short, the result may be random. If your prompt is detailed and clear, Seedance 2 has a much better chance of giving you the video you want.
Try to include:
who the character is;
what the character is doing;
where the scene takes place;
what the lighting looks like;
what camera movement you want;
what mood or style the video should have;
what details must stay consistent.
Here is an example prompt:
Create a realistic cinematic video of @reference walking confidently through a neon-lit city street at night. Keep the same face, hairstyle, facial proportions, skin tone, and overall appearance as in the reference collage. The character is wearing a stylish black jacket, looking calm and focused. Smooth camera movement, shallow depth of field, realistic street lights, detailed background, natural facial expression, high-quality movie-style color grading.
This kind of prompt gives the AI much more direction than simply writing “make a video of this person walking.”
Step 5: Keep the Appearance Consistent from Frame to Frame
One of the biggest goals in AI video generation is face consistency. You don’t want the character to look like one person at the beginning of the clip and someone else at the end.
To improve consistency, use phrases like:
- keep the same face throughout the video;
- preserve the facial features from the reference;
- maintain the same hairstyle and proportions;
- consistent identity in every frame;
- no face changes between shots;
- same character appearance from start to finish.
These details help the model understand that identity preservation is a priority.
Example Seedance 2 Prompt for Realistic AI Video
Here’s another ready-to-use prompt:
Generate a cinematic AI video featuring @reference sitting in a cozy coffee shop near a large window during golden hour. The person keeps the same facial features, hairstyle, face shape, skin tone, and overall appearance as shown in the reference collage. Soft warm sunlight enters through the window, creating a natural glow on the face. The camera slowly moves closer, capturing a calm and thoughtful expression. Realistic background, smooth motion, natural lighting, shallow depth of field, high-detail skin texture, cinematic atmosphere.
You can adapt this prompt to almost any scene: city streets, luxury interiors, office spaces, fantasy environments, music videos, product ads, social media clips, and more.
Where This Workflow Can Be Useful
This method is useful for many types of AI video projects, including:
personal AI avatars;
influencer-style content;
brand ambassadors;
fictional characters;
short cinematic clips;
music videos;
advertising creatives;
social media videos;
storytelling projects;
character-based content series.
If you are building a recurring AI character, having a stable reference collage is especially helpful. You can use the same collage across multiple prompts and generate different videos while keeping the character recognizable.
