绝大多数场景下，使用这种方式即可合成视频。接口参数和返回字段请参见ProduceEditingProjectVideo。调用示例如下：

说明

通过时间线实现剪辑合成的更多Timeline示例请参见视频剪辑-使用示例。

// 调用样例
var client = initVodClient('<Your AccessKeyId>','<Your AccessKeySecret>');

// Build Editing Project Timeline
var timeline = {
    // Video Track
    VideoTracks: [{
        // Video Track Clips
        VideoTrackClips: [{
            MediaId: 'MediaId1'
        },{
            MediaId: 'MediaId2'
        }]
    }]
};
// Set Produce Media Metadata
var mediaMetadata = {
    Title: 'Title',  // Produce Media Title
    Description: 'Description',  // Produce Media Description
    CoverURL: 'http://test.testvod123.com/media/cover/mediaid.jpg',  // Produce Media UserDefined Cover URL
    CateId: null,   // Produce Media Category ID
    Tags: 'Tag1,Tag2'   // Produce Media Category Name
};
// Set Produce Configuration
var produceConfig = {
    /*
     生成过程可以生成媒体夹层文件。您可以使用夹层文件来转码其他媒体文件，就像文件上传完成后的转码过程一样。此字段描述生产夹层完成后的Transocde TemplateGroup ID。
     1. Not required
     2. Use default transcode template group id when empty
     */
