Firstly, videos have the ability to tell a story or convey a message in a dynamic and immersive way, capturing the audience's attention more effectively. 

Additionally, videos often include movement, sound, and visual effects, which can stimulate multiple senses and create a more memorable experience for viewers. Moreover, videos allow for greater flexibility in content delivery, enabling creators to incorporate humour, emotion, or educational elements that resonate with audiences on a deeper level. 

Lastly, with the increasing prevalence of autoplay features on social media platforms, videos have a higher likelihood of grabbing users' attention as they scroll through their feeds compared to static images. Overall, the combination of storytelling capabilities, sensory stimulation, and enhanced engagement opportunities makes video content a powerful tool for capturing and retaining audience interest on social media platforms.
