    Intelligent Media Services:Produce a video after intelligent data processing

    Last Updated:Dec 10, 2024

    This topic describes how to configure the Timeline parameters in the SubmitMediaProducingJob operation to produce a video after intelligent data processing.

    Usage notes

    • Intelligent production supports editing and compositing, effect rendering, and templates for live streams, VOD files, and material files from Object Storage Service (OSS). For more information, see Intelligent production overview.

    • You can produce a video from one or more videos, audio files, images, and subtitle materials by configuring Timeline parameters and calling the SubmitMediaProducingJob operation.

    • A timeline is created when you add materials and configure effects to create a video. A timeline consists of tracks, materials, and effects. For more information, see Timeline configurations.

    • For more information about how to use the IMS SDK to edit audio and video files, see Preparations.

    Use AI_ASR to convert speech to text and add the text to a video

    You can add the "Type": "AI_ASR" setting to convert speech to text. You can also set the subtitle style, such as the font and color.

    Note

    The feature of converting speech to text is available in the China (Shanghai), China (Beijing), China (Hangzhou), and China (Shenzhen) regions.

          "Italic": false,
          "Underline": false
        }
      }]
    }]
  }]
}

    Use AI_TTS to convert text to speech and add the speech to a video

    You can add the "Type": "AI_TTS" setting to convert text to speech. This setting can be used together with "Type": "AI_ASR". Content indicates the text that you want to convert. You can also set speech properties, such as Voice, SpeechRate, PitchRate, and Format.

    Note

    • The feature of converting text to speech is available in the China (Shanghai), China (Beijing), and China (Hangzhou) regions.

    • By default, AI_TTS splits sentences based on punctuation marks such as commas (,) and periods (.). You can define the subtitle style and line break mode for each split sentence.

    Use AI_TTS to convert text to speech and use SSML to control the rhythm or pronunciation

    The Content field in AI_TTS supports the Speech Synthesis Markup Language (SSML) markup language. It can be used to correct the pronunciation of specialized words, add pauses, and add different emotions and styles to the speech.
