A tagpanel in sports video analysis refers to a dedicated interface or tool that allows users to tag and annotate videos during live events or post-game analysis. It provides a user-friendly environment to efficiently add metadata and mark important moments in a game.

Tagpanels are designed to streamline the tagging process, enabling coaches, analysts, and other users to easily add tags, timestamps, player information, and other relevant data. They offer customizable templates for sport-specific events and actions, making it easier to generate detailed insights and reports.
