Engaged Duration

comScore Video Metrix provides the most comprehensive and useful duration measurement, providing visibility into only the engaged time spent viewing online video. 

Engaged duration records time spent viewing online video based on:

•  Tag records
•  Which windows are active and visible on the screen
•  Streaming URL records
•  Video Metadata
•  and refined outlier trimming

Engaged duration reduces noise, such as users who leave videos playing for hours on an idle computer, and ensures visibility into duration of encrypted content.
