Short answer

Video quartile reporting shows how many video ad views reached 25%, 50%, 75%, and 100% of the ad's length. By revealing where viewers drop off, it helps advertisers judge creative effectiveness and attention, compare placements, and calculate completion rates. The quartile events are typically tracked through VAST tracking URLs.
