Teamtags are a feature in video analysis software that allows users to create and use tags with a fixed name and length across multiple games or sessions. These tags help streamline the tagging process, especially in team sports where certain actions or events are recurrent. By using Teamtags, coaches, analysts, and athletes can quickly assign relevant tags to specific moments or actions during games or training sessions by simply pressing a key. It saves time and ensures consistency in tagging across different events.
