유튜브 썸네일의 시각 속성의 정량화와 구독자 수 대비 초기 조회수 비율에 관한 실증적 연구

초록

This study examined the association between YouTube thumbnail visual attributes and the Initial Views-to-Subscribers Ratio (SVR), an early-stage performance metric, using 471 samples quantified via OpenCV, Tesseract OCR, and MediaPipe Face Detection. Multiple regression analysis showed that color contrast and dominant color saturation were significantly associated with higher SVR, consistent with enhanced visual salience, whereas text density was negatively associated with SVR, consistent with increased cognitive load. Independent-samples t-test results further indicated that thumbnails containing a human face showed a significantly higher mean SVR than those without, and one-way ANOVA confirmed significant differences in mean SVR across content genres, in line with genre-based audience gratification. Based on these associations, this study proposes exploratory reference ranges for thumbnail design (contrast ratio above 8.0; text occupancy of 10–15%), offering academic and practical value for data-driven thumbnail design research.
