您的一家美发沙龙客户投放了一个新的视频广告系列，其中大部分信息都是从 25 秒这一时刻开始播出的。您想要了解这部分信息获得的观看次数。为此，您应当查看 Campaign Manager 360 报告功能中的下面哪个视频基准？

The correct answer is "Active View: Custom metric visible impressions" because this metric allows you to define a specific point in the video (like 25 seconds) and track impressions that were visible at that moment. This directly addresses the client's need to understand views for the crucial part of their video starting at 25 seconds. "Active View: Video completions" would only tell you how many times the entire video played, not specifically when the 25-second mark was reached. "Active View: Companion conversions" and "Active View: Companion views" relate to companion banners or ads, not the main video content itself.
