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.

UnverifiedCharacter consistency (maintaining uniform appearance of the same character across different frames) is currently the key technical difficulty affecting the quality of the finished video.76% similarUnverifiedWhen the reference image character and the driving video subject differ significantly in body proportions, clothing style, or range of motion, there is an inherent tension between the stable injection of identity features and the precise alignment of motion structure.74% similarUnverifiedCreator proposes a 'lineup image' mechanism specifically optimized for the problem of inconsistent character proportions in multi-character combinations, where the Reference Image and Prompt enter the storyboarding and video generation pipeline together.73% similarUnverifiedInconsistencies in character features and lighting style across reference images can cause flickering, distortion, and identity drift in video generation.71% similarVerifiedIdentity drift is a systemic flaw in diffusion-model-based video generation systems: because the model does not maintain explicit character state between frames and instead relies on attention mechanisms and soft constraints from reference images, the character's face, hairstyle, and clothing gradually shift over time steps.71% similar
