Character consistency is a production discipline, not a magic phrase. A recurring subject is more likely to remain recognizable when the project starts with clear references, records the identity-defining traits, changes shots in controlled steps, and reviews every result beside its neighbors.
Record what makes the character recognizable
Choose a small set of clear reference images: a neutral front or three-quarter view, a useful full-body frame, and any approved wardrobe or prop detail that matters to the story. More references are not automatically better; contradictory references create ambiguity.
Write identity notes in visible terms:
- face shape and distinctive features;
- hair color, length, texture, and part;
- approximate age range and body proportions;
- stable wardrobe pieces and accessories;
- recurring props, marks, or silhouette cues;
- details that may change from scene to scene.
Do not fill the packet with biography the camera cannot see. Translate story into observable choices: posture, wardrobe wear, habitual gesture, or expression.
Recurring character: woman in her early thirties with a narrow oval face, warm brown skin, short dark curls parted left, and a small silver hoop in the right ear. Stable outfit: moss overshirt over a cream T-shirt. Keep the curl shape, face proportions, earring, and overshirt consistent. Expression and pose may change by scene.
Change one major visual variable at a time
A sequence that moves from a medium kitchen portrait to a slightly wider shot in the same light asks less of the model than a jump to an aerial night scene with a different outfit and extreme action. Create a shot ladder that expands gradually where the story allows.
Record continuity between shots: which hand holds an object, which side of frame the character occupies, where they look, what they wear, and what time of day the scene implies. Consistent identity cannot rescue contradictory spatial direction.
Use image-to-video when a reference frame should establish the opening appearance. Use text-to-video more selectively for shots where open exploration is acceptable.
Keep reference and motion instructions in separate jobs
Let the reference establish appearance. Use the prompt to explain the action, camera, environment, and timing. Repeating the full identity description in different language on every shot can introduce accidental variation.
When a result gets the face right but the action wrong, revise the action. When the action works but identity drifts, return to a clearer source frame or a more compatible composition. Change one variable at a time so the team knows which adjustment affected the result.
Run a continuity pass across the full sequence
Create a contact sheet or place neighboring clips side by side. Check:
- Face proportions, eye spacing, nose, jaw, and hairline.
- Hair texture, length, part, and motion.
- Body proportions, hands, and movement.
- Wardrobe color, cut, closures, and accessories.
- Props, environment, light direction, and time of day.
- Screen direction and the logic of the cut.
Replace the weakest continuity break, not necessarily the least beautiful shot. A coherent sequence usually feels more professional than a collection of individually striking but incompatible clips.
Frequently asked questions
Can AI keep a character perfectly identical?
No reliable workflow should promise perfect identity in every generated frame. References, compatible shots, stable direction, and structured review reduce drift but do not eliminate it.
How many reference images should I use?
Use the smallest set that clearly establishes the identity and required views. Remove blurry, conflicting, outdated, or visually inconsistent references.
Should wardrobe be part of the identity?
Only when it needs to stay stable. Separate identity features from scene continuity so a planned wardrobe change does not become an accidental face change.
Which Brevity model should I choose?
The right choice depends on the input, shot length, aspect ratio, and controls you need. Compare the exact current variants on the Brevity model pages and test a representative shot before committing a whole sequence.
