PodReels: Human-AI Co-Creation of Video Podcast Teasers

Abstract

Video podcast teasers are short videos that can be shared on social media platforms to capture interest in full episodes of a video podcast. These teasers enable long-form podcasters to reach new audiences and gain more followers. However, creating a compelling teaser from an hour-long episode can be challenging. Selecting interesting clips requires significant mental effort; editing the chosen clips into a cohesive, well-produced teaser is time-consuming. To support the creation of video podcast teasers, we first investigated what makes a good teaser. We combined insights from audience comments and creator interviews to identify key ingredients. We also identified a common workflow used by creators during this process. Based on these findings, we developed a human-AI co-creative tool called PodReels to assist video podcasters in crafting teasers. Our user study demonstrated that PodReels significantly reduces creators’ mental demand and improves their efficiency in producing video podcast teasers.
