The series is not based on the repetition of a prompt, but on an immutable passport of the character.
If each frame is redescribed, the model decides anew the age, proportions and character of the face. The stable series separates the constant characters, scene variables, and technical parameters.
Collect your passport before the first generation
The passport is a short, unalterable block: age group, face shape, eye fit, nose, hairline, physique and one or two features. Don't include clothing, background and emotion if they have to change. The more random details are declared permanent, the harder it is to construct new scenes.
Oval, cheekbones, eyes, nose, mouth and recognizable asymmetry.
Length, growth line, color and basic texture.
Growth ratio and silhouette without accurate measurement.
A calm look, a manner of holding, but not one fixed posture.
One strong reference is more useful than five contradictory
The main frame should clearly show the face and hairstyle. The second one is only needed if it reveals missing information - profile, clothing or full height. If the references are taken at different ages, with heavy retouching and incompatible angles the model averages them.
Change the scene in a separate layer
For each frame, describe only the variables: location, action, clothing, light, plan and mood. Copy your character's passport verbatim so you can figure out exactly what caused the drift, and return the previous version without rewriting the entire instruction manual.
How to notice the drift to the tenth frame
After each result, compare not only with the previous one, but also with a benchmark. Otherwise, small changes accumulate: just a little chin, above the eyebrows, larger than the eyes - and the sixth frame already looks like the first only in hairstyle.
- Reduce all frames to one size.The silhouette and setting of the eyes will become more noticeable than the decor.
- Compare the three stable zones.Facial contour, nose and hairline.
- Don’t use the latter as a new benchmark.Go back to the original reference.
- Regenerate only the dropped frame.Do not change your passport because of a single error.
Reproduced six-step process
Select a standard, write your passport, create a neutral control portrait, get a good wording, add one scene each and do the same check after each frame. Change your clothes and posture only after you have your face stable in two or three simple scenes.
For a long series, keep the source, passport, permission list and frame sheet nearby. This is more boring than random generation, but allows you to continue the project in a week and get the same hero.
What to do if the series has already begun to break up
Don't fix your face with a do-it-yourself command. Find the first frame where there's a specific difference: chin, eye size or hairline changed. Return the reference, leave the scene of the problem frame and name one geometric correction. If you swam the face, body and style at the same time, it is cheaper to recreate the frame from the benchmark than continue editing the derivative.
Sometimes it's the scene: an extreme profile hides half of the features, a wide-angle camera changes proportions, and heavy makeup erases asymmetry. First bring the angle and light closer to those where the character is already stable, then gradually increase complexity.
Consistency is a manageable constraint, not a successful one.
Set the passport and the benchmark, separate the constant from the variable, check each frame against the first one, then the series grows without gradually replacing the character.
