Frame Rate Matching Principle Validation: Signal Extraction Efficiency in High Frame Rate Video Production (48-120fps)

Primary Research Question: Does the Frame Rate Matching Principle—established for standard production video (24-30fps native)—generalize to high frame rate content (48fps, 60fps, 120fps native)? Secondary Research Questions: 1. What percentage of visual signal information is lost when extracting at 24fps from 60fps native content? 2. Do different signal categories (scene, character, object, atmosphere, action, temporal) show different sensitivity to frame rate downsampling? 3. Does the relationship between extraction fps and signal capture differ for high-fps content vs. standard-fps content? Hypotheses Null Hypothesis (H0): For video content natively produced at >30fps, signal capture efficiency when extracting at 24fps equals signal capture efficiency when extracting at the native frame rate (SCR ≥ 97%), consistent with the Frame Rate Matching Principle observed in 24-30fps content. Alternative Hypothesis (H1): High frame rate content (>30fps native) contains visual information that is lost when downsampling to 24fps extraction (SCR < 97%), indicating that high-fps production captures temporal information not present in standard-fps production. Directional Prediction: We predict H1 will be supported, with measurable information loss (SCR = 85-95%) when extracting at 24fps from 60-120fps native content, particularly for motion-dependent signals (action, temporal categories).
