Abstract

Cultural adaptation in trailers often stops at transferring symbols to the screen, while the relationship between symbols, character movement, and visual-effects decisions is rarely documented as reproducible knowledge. This study formulates and applies a rotoscoping-motion-tracking-compositing workflow in the Darah Dang Tuanku trailer so that the karih functions as a trigger of character transformation rather than as a decorative prop. The study adopts a practice-based design approach using the script, storyboard, live-action footage, Adobe After Effects and Adobe Premiere Pro interface records, and output frames. The workflow comprises narrative-beat mapping, footage acquisition, subject isolation, effect anchoring at the shoulder, hand, and chest, lightning compositing, color grading, and shot-level visual auditing. The audit examines edge continuity, spatial attachment, layer integration, character legibility, cultural-symbol function, and workflow traceability. Results show that prioritizing mask continuity and motion anchors keeps the lightning attached to character action, while the cool-to-red palette shift directs the transition from vulnerability to awakening. The karih becomes a causal node connecting Dang Tuanku's legacy, conflict, and Malik's transformation. Five audit criteria were met in the selected documentation, whereas fine-edge continuity still required manual correction during rapid motion. The findings indicate that successful rotoscoping in small-scale production depends on an explicit relationship between narrative function and technical decisions. Audience reception and external cultural validation were not tested and remain priorities for further research.
