How to Create a Consistent AI Character Across Photos and Videos
A practical workflow for building one recognizable AI character, directing a coherent photo set, and turning selected stills into short videos.

There is no honest universal winner for photorealistic people. The best model depends on whether you value prompt adherence, natural skin, full-body anatomy, character reuse, editing control, speed, or cost.
Instead of publishing an unsupported ranking, this article documents a comparison method you can repeat inside Lucidpic as models change.

Use the same prompt for every model:
Editorial full-body photograph of an adult woman in her early thirties, short dark wavy hair, olive linen suit and white trainers, standing outside a quiet modern gallery after light rain, natural overcast daylight, realistic skin texture, relaxed posture, 50mm photography, vertical 4:5 composition.
Keep the aspect ratio at 4:5, use one output per run, leave seed handling at the model's supported default, disable prompt rewriting where the interface allows it, and record the model name and date. Do not cherry-pick ten generations from one model against one generation from another.

Evaluate each output at thumbnail size and full resolution:
| Area | Question |
|---|---|
| Person | Does the age, hair, wardrobe, and overall presentation match? |
| Face and skin | Do features, pores, hair edges, and expression feel coherent? |
| Full body | Are posture, hands, feet, and clothing construction plausible? |
| Scene | Did the model include the gallery, wet ground, and overcast light? |
| Photography | Does the image read as a 50mm editorial photograph rather than illustration? |
| Editability | Is there enough clean structure for refinement or image-to-video? |
For each model available in the Studio, record observations in plain language. One may produce the most natural skin but simplify the suit. Another may follow wardrobe and architecture closely but create a more polished commercial finish. A third may be especially useful when you need readable environmental detail.

Those are task-specific observations, not a permanent ranking. Providers update models, defaults change, and a portrait prompt can produce a different ordering from a full-body campaign image.
For a one-off portrait, prioritize face quality and photographic texture. For the AI person generator, consider whether the result is a strong foundation for a reusable character. For full-body images, inspect hands, footwear, clothing, and stance. For an AI photoshoot, test whether the model follows a repeatable art direction across several prompts.
If the still will become video, leave room for motion and avoid fragile small details. The strongest single image is not always the most stable source for image to video.
Run the same prompt, save the settings, inspect the same criteria, and choose the model whose weaknesses are easiest to manage for the current job. Re-run the test when a model version or important setting changes.

Why AI image tools reject some legitimate prompts, what "uncensored" usually promises, and how model choice and fallback can give creators more room without removing safety rules.
