Paper Abstract

The effect of low sample frame rate on interpretability is often confused with the impact it has on encoding processes. In this study, the confusion was avoided by ensuring that none of the low-frame rate clips had coding artifacts. Under these conditions, the lowered frame rate was not associated with a statistically significant change in interpretability. Airborne, high definition 720P, 60 FPS video clips were used as source material to produce test clips with varying sample frame rates, playback rates, and degrees of target motion. Frame rates ranged from 7.5 FPS to 60 FPS. Playback rates ranged up to 8X normal speed. Target motion ranged from near zero MPH up to 300 MPH.
