The Frame Rate Matching Principle: Video Signal Extraction Reliability Across Frame Rates

Research data and reproducibility package for "The Frame Rate Matching Principle" study. Key Finding: Signal Capture Rate (SCR) = min(f_extraction / f_source, 1.0) When extracting narrative signals from video using Vision-Language Models, extraction rates beyond the source video's frame rate provide no additional signal capture benefit. This package includes: - Study 0: 4,042 signal extractions from 24fps content (15 frame rates tested) - Study 1: 387 signals from native HFR content (48-120fps validation) - Full analysis code, figures, and statistical results - Pre-registered on OSF: https://osf.io/8jz3b Effect size: η² = 0.847 (large), Cohen's d = 1.99 (very large)
