Online learning via videos is increasingly emerging as a popular educational medium due to its flexibility in time and accessibility. This review analyzed the main elements that influence the effectiveness of educational videos, with a specific focus on evaluating the relationship between video characteristics and their attractiveness. Specifically, it discussed the effect of the presenter's appearance, personality, and non-verbal behaviors on student engagement and learning outcomes. In addition, it reviewed the influence of various video traits, such as segmentation and communication, on viewers engagement and satisfaction. This paper also evaluated the benefits of interactive videos compared to linear versions. The results emphasize the crucial function of the presenter and the quality of visuals in improving video consumption and learning outcomes. Moreover, interactive aspects can contribute to a moderate improvement in learner satisfaction. However, the previous study is constrained by limited participants and targeted online learning platforms. Future studies should investigate the effectiveness of online learning in participants with a wide range of socioeconomic backgrounds using personalized video designs.
