基于模板的TimeLine配置示例

通常在没有模板情况下，对时间线素材 整体静音添加黑色字体字幕特效，需要写如下配置：

{
    "VideoTracks": [
        {
            "VideoTrackClips": [
                {
                    "MediaId" : "****7e05512043f49f697f7425b9****",
                    "Effects": [
                        {
                            "Type": "Volume",
                            "Gain": "0",
                        },
                        {
                            "Type": "Text",
                            "X": "10",
                            "Y": "10",
                            "TimelineIn": "0",
                            "Font": "WenQuanYi Zen Hei Mono",
                            "Content": "测试标题1",
                            "FontSize": 26,
                            "FontColorOpacity": 0.2,
                            "FontColor": "#000000",
                        }
                    ]
                },
                {
                    "MediaId" : "****d22788e810116a45109f2ea8****",
                    "Effects": [
                        {
                            "Type": "Volume",
                            "Gain": "0",
                        },
                        {
                            "Type": "Text",
                            "X": "10",
                            "Y": "10",
                            "TimelineIn": "0",
                            "Font": "WenQuanYi Zen Hei Mono",
                            "Content": "测试标题2",
                            "FontSize": 26,
                            "FontColorOpacity": 0.2,
                            "FontColor": "#000000",
                        }
                    ]
                },
                {
                    "MediaId" : "****f167f44f4964e6c998dee827****",
                    "Effects": [
                        {
                            "Type": "Volume",
                            "Gain": "0",
                        },
                        {
                            "Type": "Text",
                            "X": "10",
                            "Y": "10",
                            "TimelineIn": "0",
                            "Font": "WenQuanYi Zen Hei Mono",
                            "Content": "测试标题3",
                            "FontSize": 26,
                            "FontColorOpacity": 0.2,
                            "FontColor": "#000000",
                        }
                    ]
                }
            ]
        }
    ]
}

当使用了模板后，配置简化如下：

{
    "VideoTracks": [
        {
            "VideoTrackClips": [
                {
                    "Sys_Type" : "Array",
                    "Sys_ArrayObject" : "$VideoArray",
                    "Sys_Template" : {
                        "MediaId" : "$MediaId",
                        "Effects": [
                            {
                                "Type": "Volume",
                                "Gain": "0"
                            },
                            {
                                Sys_Type : "Template",
                                Sys_TemplateID : "IceSysDemo_BlackColorTitle",
                                Sys_Params: {
                                    Title : "$Title",
                                }
                            }
                        ]
                    }
                }
            ]
        }
    ]
}

其中此部分是引用了 黑色字体字幕特效 模板：

{
    Sys_Type : "Template",
    Sys_TemplateID : "IceSysDemo_BlackColorTitle",
    Sys_Params : {
        Title : "$Title",
    }
}
