Abstract
This study presented a fuzzy logic framework to optimize the camera angles and Field of View (FOV) in the documentation of Indonesian traditional dances, specifically the Remo dance. The system utilized BioVision Hierarchy (BVH) Motion Capture (MoCap) data to dynamically modify the camera settings according to movement characteristics, such as velocity and spatial complexity. The framework incorporated five camera perspectives (eye level, low angle, high angle, frog angle, bird's eye) and three classes of FOV (narrow, medium, wide). The results indicated that a low angle with a narrow FOV most effectively captured the dramatic hand motions, whereas an eye level perspective with a medium FOV was appropriate for the neutral transitions. Validation by five specialists in dance and five in cinematography resulted in a Mean Opinion Score (MOS) of 79%, affirming the system's conformity with the conventional dance philosophy. The current approach decreased the manufacturing time by 25% and enhanced the adjustment precision compared to traditional methods. Future work will broaden the validation to additional dancing styles and integrate machine learning for improved accuracy.
