本文介绍了视频质量评估的最佳实践，用于在自适应流应用中为多比特率视频编码选择最佳配置文件。配置文件是一组特定的比特率、帧速率和分辨率设置。本文提出的方法旨在在最终用户设备上实现最佳视频质量。该方法可应用于主观和客观数据集。本文件是与视频服务论坛（VSF）合作编写的。

This document presents best practices for video quality assessment to be used to select optimal profiles for multi bit rate video encoding in adaptive streaming applications. A profile is a specific set of bit rate, frame rate, and resolution settings. The methodology presented here is intended to achieve the best video quality on end-user devices. The methodology may be applied to both subjective and objective data sets. This document was produced in collaboration with the Video Services Forum (VSF).
