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ProduceEditingProjectVideo - 视频合成提交合成任务时，通过设置参数ProduceConfig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": [{
      "MediaId":"756620ed48c9af022c66ee1cbe2e****"
    },{
      "MediaId":"8f5cdf044b059b3adc7967ba1cbe****"
    },{
      "MediaId":"70dc95c0e31b71edbfe76fa3691c****"
    }]
  }]
}
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ProduceEditingProjectVideo - 视频合成提交合成任务时，通过设置参数ProduceConfig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": [{
   "MediaId":"756620ed48c9af022c66ee1cbe2e****"
  }, {
   "MediaId":"8f5cdf044b059b3adc7967ba1cbe****"
  }, {
   "MediaId":"70dc95c0e31b71edbfe76fa3691c****"
  }]
 }],
 "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": [{
   "MediaId":"222d9296e8864746a0b6f32dad6e****",
   "Type": "GlobalImage"
  }]
 }, {

   "Effects": [{
    "Type": "Volume",

   }]
  }, {
   "MediaId":"333d9296e8864746a0b6f32dad5e****",
