短视频常用功能的Timeline示例_智能媒体服务-阿里云帮助中心

通过配置Timeline提交剪辑合成作业时，您需要根据实际业务需求配置此参数。通过阅读本文，您可以了解短视频常用功能的Timeline示例。

属性说明

以下示例中的属性详情，请参见Timeline配置说明。

Timeline示例

视频横转竖——补充上下黑边

如果Timeline中的素材为横屏视频，在调用接口SubmitMediaProducingJob提交合成任务时，通过设置参数OutputMediaConfig中的Width和Height字段将成片视频设置为竖屏样式，系统会根据素材和成片的宽高设置将素材居中展示。

{
  "VideoTracks": [{
    "VideoTrackClips": [{
      "MediaURL": "https://your-bucket.oss-cn-shanghai.aliyuncs.com/your_video1.mp4"
    },{
      "MediaURL": "https://your-bucket.oss-cn-shanghai.aliyuncs.com/your_video2.mp4"
    },{
      "MediaURL": "https://your-bucket.oss-cn-shanghai.aliyuncs.com/your_video3.mp4"
    }]
  }]
}

说明如果您想自定义“黑边”颜色，需要在Effects字段中设置"SubType": "Color"。关于Effects具体参数说明，请参见Effect Type:Background 背景设置。

视频横转竖——补充上下模糊区域

如果Timeline中的素材为横屏视频，在调用接口SubmitMediaProducingJob提交合成任务时，通过设置参数OutputMediaConfig中的Width和Height字段将成片视频设置为竖屏样式，系统会根据素材和成片的宽高设置将素材居中展示，填充部分进行模糊处理。

    }
  ]
}

设置字幕局部效果

通过在Content字段中添加覆写代码，设置字幕局部效果。覆写代码说明如下所示：

所有覆写代码均以两个反斜杠（\\）开头。
所有局部参数覆写代码必须在{}中，且一个{}可以包含多个覆写代码。
覆写代码会作用于其后的字幕上，如果想要结束该覆写代码，需要加一个与之对应的结束覆写代码来取消该效果。

    }]
  }]
}

全局特效、滤镜

如果需要为整个视频添加特效、滤镜，需要在EffectTrack属性中添加特效，无需设置TimelineIn和TimelineOut，特效会从第0秒渲染至视频结束，常用于配置全局特效。

{
 "VideoTracks": [{
  "VideoTrackClips": [{
   "MediaURL": "https://your-bucket.oss-cn-shanghai.aliyuncs.com/your_video1.mp4"
  }, {
   "MediaURL": "https://your-bucket.oss-cn-shanghai.aliyuncs.com/your_video2.mp4"
  }, {
   "MediaURL": "https://your-bucket.oss-cn-shanghai.aliyuncs.com/your_video3.mp4"
  }]
 }],
 "EffectTracks": [{
  "EffectTrackItems": [{
   "Type": "Filter",
   "SubType": "PL2"
  }]
 }]
}

设置全局背景和全局Logo

通过配置"Type": "GlobalImage"（无需配置Duration），默认将图片从视频第0秒显示到视频结束。

{
 "VideoTracks": [{
  "VideoTrackClips": [{
   "MediaURL": "https://your-bucket.oss-cn-shanghai.aliyuncs.com/your-video/720P_background.jpg",
   "Type": "GlobalImage"
  }]
 }, {
  "VideoTrackClips": [{
   "MediaURL": "https://your-bucket.oss-cn-shanghai.aliyuncs.com/your-video/1.mp4",
   "Effects": [{
    "Type": "Volume",
    "Gain": 0
   }]
  }, {
   "MediaURL": "https://your-bucket.oss-cn-shanghai.aliyuncs.com/your-video/2.mp4",
   "Effects": [{
    "Type": "Volume",
    "Gain": 0
   }]
  }, {
   "MediaURL": "https://your-bucket.oss-cn-shanghai.aliyuncs.com/your-video/3.mp4",
   "Effects": [{
    "Type": "Volume",
    "Gain": 0
   }]
  }, {
   "MediaURL": "https://your-bucket.oss-cn-shanghai.aliyuncs.com/your-video/4.mp4",
   "Effects": [{
    "Type": "Volume",
    "Gain": 0
   }]
  }, {
   "MediaURL": "https://your-bucket.oss-cn-shanghai.aliyuncs.com/your-video/5.mp4"
  }]
 }, {
  "VideoTrackClips": [{
   "MediaURL": "https://your-bucket.oss-cn-shanghai.aliyuncs.com/your-video/aliyun_logo_white.png",
   "Type": "GlobalImage",
   "X": 0.1,
   "Y": 0.1,
   "Width": 247,
   "Height": 74
  }]
 }]
}

语音转文字并将字幕合并到视频中

设置"Type": "AI_ASR"可以将音视频中的语音转换成文字，同时可以设置字幕样式，例如：字体、颜色等。

说明语音转文字服务只支持华东2（上海）、华北2（北京）和华东1（杭州）地域。

{
  "VideoTracks": [{
    "VideoTrackClips": [{
      "MediaURL": "https://your-bucket.oss-cn-shanghai.aliyuncs.com/your_video7.mp4",
      "Effects": [{
        "Type": "AI_ASR",
        "Font": "AlibabaPuHuiTi",
        "Alignment": "TopCenter",
        "Y": 910,
        "Outline": 10,
        "OutlineColour": "#ffffff",
        "FontSize": 60,
        "FontColor": "#000079",
        "FontFace": {
          "Bold": true,
          "Italic": false,
          "Underline": false
        }
      }]
    }]
  }]
}

文字转语音并将语音合并到视频中

设置"Type": "AI_TTS"可以将文字转换成语音，可以与"Type": "AI_ASR"共用。其中，Content为要转换的文字，同时可以设置语音属性，例如：Voice、SpeechRate、PitchRate、Format等。

说明文字转语音和语音转文字服务都只支持华东2（上海）、华北2（北京）和华东1（杭州）地域。
