A practical film bible for consistent AI characters
A concise character and continuity reference helps you review generated shots without repeating conflicting instructions.
Separate identity from the moment
A character reference should distinguish stable identity from scene-specific choices. Stable details include a character’s age range, face shape, hair and distinguishing features. Scene details include clothing, lighting, expression, pose and camera distance. Mixing every scene instruction into the identity description makes the reference harder to reuse. For a recurring character, write a short identity description and then attach a separate note for the current scene.
Record what the camera can verify
Replace abstract labels with visible information. “Confident” could mean an upright posture, a steady gaze or a deliberate pace; choose the behavior that belongs in the scene. Specify the coat, bag or other recurring prop clearly enough to recognize it again. Do not add so many small details that the important ones become impossible to judge. A good reference helps a reviewer say why one take matches and another does not.
Keep reference images organized
Choose reference images that clearly show the traits you want to preserve. Give each reference a purpose: identity, outfit, location or composition. A location image should not silently redefine the character’s clothes, and a lighting study should not become the only face reference. Use only material you have permission to use, and obtain appropriate consent for recognizable people. Keep a note explaining the origin and intended role of each reference.
Track continuity between shots
Make a simple table with shot number, outfit, props, position, screen direction and time of day. If a character holds a cup in the first shot, decide whether it is still present in the next one. If the camera crosses the action axis, decide whether that change is intentional. These ordinary filmmaking details often matter more than adding another stylistic phrase to a generation prompt. Review adjacent shots together, rather than judging each output in isolation.
Revise a reference deliberately
When an approved design changes, record the change and identify which shots need review. Do not keep several unnamed versions and hope the next request picks the right one. Save a useful failed example with a brief explanation, such as “face matches, jacket does not.” That makes revision evidence-based. A character sheet is a living production document, but it should not change by accident between every generation.
Understand what a film bible can and cannot do
A film bible organizes creative intent; it cannot guarantee that every model follows every reference. Model capabilities, settings and source material still affect the result. Fylmer presents the Film Bible as part of its connected filmmaking workspace, alongside script, shots and edit. Its public site states that the product remains in development and that supported model connections are needed to generate media. Treat continuity review as a required production step, even when the project’s organization is handled in one place.
