Abnormal Facial Expression: Facial movements appear robotic or distorted because only certain parts of the face move (e.g., the mouth moves while the eyes and cheeks stay frozen), or muscles pull in unnatural directions during intense expressions.

Dynamic and Kinematic Inconsistency: Movement breaks basic physics regarding trajectory, speed, or environmental interaction(rather than object shape), such as parts of a single solid object moving at different speeds, incorrect relative motion between a moving subject and its background, or fluids like water and smoke failing to splash or flow according to inertia.

Action Without Consequence: An action is performed but produces no physical reaction or change in the target object, such as spilling water without wetting the ground or eating without the food amount decreasing.

Answer: D


Inconsistent Blur: Blur that is spatially incoherent and cannot be explained by depth-of-field or motion blur. Manifests as arbitrary local softening or loss of detail in regions that should be sharp given the scene's focus and motion context.

Color and Exposure Anomaly: Perceptual irregularities in color and luminance, characterized by: excessively vivid or artificially pure primary RGB hues; flat surfaces lacking gradient across lighting transitions; implausibly high/low exposure causing detail loss in highlights or shadows; or hard, opaque bright regions lacking the soft gradation of natural glare.

Flickering and Noise: Static surfaces exhibit shimmering, crawling patterns, or grid-like noise across frames.

Texture Inconsistency: A localized region on a continuous surface shows a perceptible break in texture density, scale, or orientation relative to its surroundings, excluding intentional design variations such as prints, patterns, or patchwork.

Unnatural Camera Motion: Jerky camera jitter, impossible physics-defying movement, or anomalies occurring during zooming or refocusings like desynchronized parallax and focus jumping.

Oversmoothing: Surfaces appear unnaturally smooth, waxy, or plastic-like, with expected micro-textures (pores, fibers, scratches) absent or visibly suppressed.

Answer: A,D


Answer: B,E


Abnormal Object Disappearance/Appearance: An object or person suddenly pops into or vanishes from the scene into thin air without being covered by anything or having a logical reason to enter or leave.

Answer: D


Answer: B,C


Unnatural Biological Motion: Living creatures move in ways that defy physics or biology, such as sliding across the ground without walking, joints bending in impossible directions, or jerky and stuttering movements.

Identical Multi-Subject Motion: Multiple characters in a scene perform perfectly synchronized actions or share the exact same facial expressions and demeanors, lacking the natural randomness and individual variance expected in a real crowd.

Answer: B,E


Feature Instability: Unjustified temporal mutation of attributes that should remain constant throughout a scene—including entity identity, body proportions, fine-grained appearance details (e.g., button count, eye color, texture patterns), and scene-bound clothing—where no narrative motivation (such as an explicit costume change or time skip) accounts for the observed shift. Extrinsic attributes that are narratively mutable (e.g., pose, expression, lighting response) are excluded from this definition.

Unnatural Morphing: Physically implausible deformations where rigid bodies exhibit non-rigid, fluid-like warping, stretching, or kinematic-violating scaling and twisting, or where any object's established basic shape undergoes unexpected distortion over time, such as an inelastic rope suddenly elongating.

Abnormal Multi-Object Merging/Splitting: Erroneous violation of object boundaries where independent entities unnaturally fuse together or a single cohesive object spontaneously fragments without external force.

Answer: C,D


Text and Symbol Unreadable: In-scene text or symbols are either severely distorted or garbled into illegible characters, or visually well-formed but semantically meaningless.

Reflection Inconsistency: Reflections on mirrors, water, or glass do not correspond to the actual scene, either misrepresenting subject position or appearance, or exhibiting unphysical distortion.

Answer: B,E


Abnormal Facial Expression: Facial movements appear robotic or distorted because only certain parts of the face move (e.g., the mouth moves while the eyes and cheeks stay frozen), or muscles pull in unnatural directions during intense expressions.

Answer: C,D


Answer: A,B


Irreversibility Violation: An irreversible physical process is unnaturally reversed or undone, such as shattered glass fragments fusing back together or a burnt object restoring itself to its original state.

Spatial Coherence: The relative positions, orientations, gaze directions, or interaction points between subjects are inconsistent—either across camera cuts (e.g., eyeline direction reverses after a cut) or within a continuous shot (e.g., two characters' relative positions drift without physical motivation). Typical failures include 180-degree rule violations, gaze mismatches where a character looks left when their interlocutor is on the right, and interaction contact points that shift between frames.

Action-Context Mismatch: Illogical behaviors or physical operations that blatantly contradict common sense, functional intent, or the established narrative context, despite adhering to basic physics. This encompasses biological absurdities (such as smelling the bottom of a bottle, fleeing towards danger, or misaligned gazes in a group photo), as well as impossible object phenomena (like a car spouting water, an intact bottle leaking, or a spaceship flying contrary to its propulsion direction).

Consequence Without Valid Action: A physical result occurs without a matching trigger or causal action, such as a skateboard rotating on its own or the volume of water increasing without any source.

Canonical Appearance Violation: The visual representation of a well-known entity violates its universally accepted appearance or canonical form or scale, such as depicting the Earth with incorrect colors or landmass distributions.

Answer: C,D,E
