What if you could learn not just which of your videos are hot on the site, but which specific parts of those videos are hotter than others? What if you could know exactly when viewers tend to leave your videos, or which scenes within a video they watch again and again? This information is now available to all YouTube video uploaders with an innovative new feature for Insight called "Hot Spots." The Hot Spots tab in Insight plays your video alongside a graph that shows the ups-and-downs of viewership at different moments within the video. We determine "hot" and "cold" spots by comparing your video's abandonment rate at that moment to other videos on YouTube of the same length, and incorporating data about rewinds and fast-forwards. So what does that mean? Well, when the graph goes up, your video is hot: few viewers are leaving, and many are even rewinding on the control bar to see that sequence again. When the graph goes down, your content's gone cold: many viewers are moving to another part of the video or leaving the video entirely.
