Signaux d’Alerte Critiques
1Rigid Shoulder and Torso Posture
The head moves and smiles naturally, but the collarbones, shoulders, and chest remain frozen like a cardboard cutout.
2Pupil Glaze and Synthetic Eye Gaze
Eyes wander without realistic micro-saccades, and pupil reflections remain fixed despite changing scene angles.
LivePortrait Implicit Keypoint Mechanics
- Implicit Keypoint Driving: Uses transformer-based keypoint optimization to warp 2D source pixels, which creates stretching artifacts along the neck boundary.
