sampling area can vary depending on the goals and objectives

the sampling area can refer to the specific frames or time intervals within the animation that you want to focus on or analyze. It is important to choose a representative and sufficient sampling area to accurately capture the desired aspects of the animation. This can involve selecting key frames or moments that showcase important actions or changes, or it can involve sampling a continuous portion of the animation to examine movements over time. The sampling area can vary depending on the goals and objectives of the animation analysis or study.
