In this study, the video compression performance and visual quality impacts of H.264 (AVC) and H.265 (HEVC) video codecs were comparatively evaluated. The methodology employed in the research was based on quantitative and objective metrics, experimentally validated, and supported with graphical analyses. The analysis was conducted using the Hand Wash Dataset, which contains videos demonstrating the seven-step handwashing procedure recommended by the World Health Organization (WHO) and is publicly available on the Kaggle platform. The videos included in this dataset were selected because they represent realistic human action scenarios, making them suitable for evaluating visual quality and compression performance in practical applications.
