# 叉乘与时序叉乘

## <mark style="color:blue;">叉乘</mark>

* 当有【资产组】被添加至轨道后，即会自动开启【叉乘】功能
* 预览界面下方会通过【单个比例的组合视频数】，显示当前尺寸下一共可以叉乘出多少个素材
* 将鼠标悬浮在【资产组组合数】，可查看叉乘的计算方式

## <mark style="color:blue;">时序叉乘</mark>

* 至少需要添加<mark style="color:red;">两个资产组</mark>到<mark style="color:red;">主轨道</mark>才可开启【时序叉乘】
* 开启后，添加的原转场效果可能会受影响

* 被设置时序叉乘的组，在最终的组合结果中，其时间轴位置可能会被互换：如勾选A、B、C三个组时序叉乘，最后的主轨道资产组排序可能为：ABC/ACB/BAC/BCA/CAB/CBA 六种结果
* 时序叉乘会增加最终组合的视频数，为原组合生成的视频数的 N！=1\*2\*…\*n倍

* 将鼠标悬浮于【资产组组合数】或【时序叉乘组合数】，可查看计算规则与组合数的由来

## <mark style="color:blue;">叉乘 & 时序叉乘的区别</mark>

* 叉乘：资产组在时间轴上的排列顺序是固定不变的，仅资产组内的素材参与排列组合
* 时序叉乘：开启后，不仅资产组内的素材进行组合，资产组在时间轴上的排列顺序也会被打乱重组，从而增加视频的组合数
