噪声抑制Noise suppression

视频所有者启用降噪功能后,观看者可在播放期间通过它将讲话声与其他声音和音乐隔开。Noise suppression, when turned on by video owners, allows viewers to isolate speech from other sounds and music during playback. 可对每个新上传的视频启用或禁用降噪功能。Noise suppression can be switched on or off for each newly-uploaded video.

    选项视频详细信息

  • 在 "视频" 页上,选择 "更新视频详细信息"On the Videos page, select Update video details

    更新视频详细信息

当 "噪音抑制" 打开时,视频查看器将可以选择为观看的每个视频保留它或将其关闭。When noise suppression is turned on, video viewers then have the option to keep it on or turn it off for each video they watch.

如果查看器希望为单个视频打开或关闭噪音抑制,请在播放或暂停期间选择 " 噪音抑制 " 按钮。If a viewer wishes to turn noise suppression on or off for a single video, they select the noise suppression button either during playback or pause.

支持迁移到流的 Office 365 视频Support for Office 365 videos migrated to Stream

8 月2020日之后:迁移到流的任何 Office 365 视频的所有者都可以从视频的编辑页面中打开噪音抑制。After August 2020: Owners of any Office 365 videos that were migrated to Stream can turn on noise suppression from within a video's Edit page. 从视频的 "编辑" 页面上的 "选项" 面板中,打开 " 噪音抑制"。From the Options panel on the edit page of the video, turn on Noise suppression.

在8月2020之前,迁移的任何 Office 365 视频的所有者都将无法打开 "噪音抑制" 选项。Before August 2020: Owners of any Office 365 videos migrated will not have the option to turn on noise suppression.

但是,以下两个简单解决方案可用于打开8月前的 Office 365 迁移视频的噪音抑制:However, here are two simple solutions for turning on noise suppression for pre-August Office 365 migrated videos:

  • 裁切旧的已迁移视频 (甚至一秒钟将执行) Trim an old migrated video (even by one second will do)
  • 将以前录制的视频替换为相同的视频Replace the previously recorded video with the same one

在上述任一解决方案完成后,所有者将能够针对这些视频打开噪音抑制。After either of these solutions is complete, an owner will be able to turn on noise suppression for these videos.
