   * **Diarization:** Distinguishes between speakers in a conversation in the output, attributing parts of the transcript to specific speakers.
   * **Multilingual transcription:** Generates multilingual transcripts. Language/locale is applied per phrase in the transcript. Phrases output when `returnDetails=true` is set. Deviating from language detection this feature is enabled when no language/locale is specified or language is set to `auto`.
 
     > [!NOTE]
     > When multilingual transcription is used, a file with an unsupported locale still produces a result. This result is based on the closest locale but most likely not correct.
     > This transcription behavior is known. Make sure to configure locales when not using multilingual transcription!

 * **Shot detection:** Identifies segments of the video aligned with shot boundaries where possible, allowing for precise editing and repackaging of content with breaks exactly on shot boundaries.
 * **Key frame extraction:** Extracts key frames from videos to represent each shot completely, ensuring each shot has enough key frames to enable field extraction to work effectively.

 * **Grouping:** Grouped faces appearing in a video to extract one representative face image for each person and provides segments where each one is present. The grouped face data is available as metadata and can be used to generate customized metadata fields when `returnDetails: true` for the analyzer.
 * **Identification:** Labels individuals in the video with names based on a Face API person directory. Customers can enable this feature by supplying a name for a Face API directory in the current resource in the `personDirectoryId` property of the analyzer.
