Metric and Dimensions Dictionary

MediaMelon utilizes its proprietary SDK to meticulously collect comprehensive data, facilitating the creation of a robust set of metrics for video analytics.

Within our framework, a set of universally recognized metrics is consistently accessible across all dimensions, while certain metrics are exclusively relevant to specific dimensions. The tabular presentation encompasses both the metric values employed in the API and the user-friendly labels integrated into the SmartSight Graphical User Interface (GUI).

It is worth noting that the majority of these metrics remain accessible for all video sessions.
