Character Consistency Across Takes
A robust template for maintaining character identity, clothing details, and anatomical proportions across multiple camera angles, temporal discontinuities, and action sequences. This four-stage scaffold systematically tests the model's capacity for identity preservation under challenging conditions: motion-induced deformation, camera angle transitions, and brief temporal gaps. Essential for validating character-grounded narrative video generation.
Stages
A character in a specific outfit standing in a defined environment. Establishing shot, neutral lighting. The character wears a navy blue wool coat with brass buttons, charcoal trousers, and brown leather boots. Hair is dark brown, shoulder-length, with a slight wave. Facial features: high cheekbones, defined jawline, warm brown eyes. Environment: urban park at dusk, soft ambient lighting from street lamps, autumn foliage in background.Establish the complete character identity vector — clothing, hair, facial structure, and environmental context as a unified reference state.
The character moves through the space at a natural walking pace. Clothing folds respond realistically to motion — coat hem sways, trouser fabric stretches at the knee. Hair moves with subtle wind interaction. Body proportions remain anatomically consistent: arm swing, stride length, and posture all conform to human biomechanics. No elongation, compression, or proportion drift.Test physics-informed motion: the model must apply correct cloth simulation and anatomical constraints during locomotion.
Camera cuts to a different angle (from front three-quarter to side profile). Character identity and outfit details must remain unchanged. The brass buttons on the coat maintain their exact arrangement and reflective properties. Hair silhouette from the new angle matches the established style. Facial features (nose profile, ear shape) are consistent with the original identity. No identity drift or feature morphing.Critical test for multi-view identity coherence: the model must maintain a consistent 3D character model across viewpoint transitions.
A brief time jump (approximately 4 seconds). The character returns to frame in the same state — same outfit, same hair configuration, same facial expression baseline. No accumulated wear on clothing, no hair displacement, no aging or fatigue indicators. The temporal discontinuity is seamless; the character appears to have paused in their exact state during the gap.Validates temporal state preservation: the model must understand that brief time jumps should not introduce cumulative visual changes.
