This document summarizes a webinar on the cost of errors for video streaming platforms. It discusses how most error codes are ambiguous and do not clearly indicate the root cause of issues. It then estimates the potential costs of errors for subscription video on demand (SVOD) platforms and ad-supported video on demand (AVOD) platforms based on subscriber churn rates and lost ad revenue from viewers abandoning videos. Finally, it discusses how collecting additional error data could help reduce error rates and the associated costs.
