Character Drift
Character drift refers to the phenomenon in AI image generation or comic creation where the visual appearance of the same character deviates across different scenes or storyboard panels. It is one of the core technical challenges in the AI comic generation field.

Heavy style words (such as "oil painting", "anime" or "cinematic") may override facial features and cause drift, so the style should be written into the character card as fixed and not changed again.
Character drift refers to the phenomenon in which the same character generated by AI in images or videos has inconsistent appearance features across different scenes.
Changing multiple variables at once—such as location, pose, lighting and camera—almost inevitably causes character drift.
Extreme close-ups and wide-angle long shots easily cause character drift; medium shots are the safest.
Role drift refers to the phenomenon in which, during a long conversation, the model gradually deviates from its initial role setting, usually caused by the continuous accumulation of the context window diluting the weight of early constraints.
Mainstream approaches to solving character drift include using character reference images as conditional inputs (IP-Adapter-type methods), introducing consistency constraints in the latent space, and maintaining cross-segment coherence through multi-frame joint generation.
Engineering approaches to solving character drift include periodically re-injecting character profile summaries, performing character consistency checks on outputs, and internalizing specific characters in the model through fine-tuning.
The root cause of character consistency issues lies in the fact that current video generation models are essentially generated independently segment by segment, making it difficult for the model to remember the precise appearance of the same character across different shots.
