# Swap & Time Sequence Swap

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

* When an \[Asset Group] is added to the track, the \[Swap(Batch Production)] function will be automatically enabled.
* At the bottom of the preview interface, \[Video Variations for a Single Ratio] will be used to display how many materials can be multiplied at the current size.
* Hover the mouse over \[Group Variations] to view the calculation method of the cross product.

## <mark style="color:blue;">Time Sequence Swap</mark>

* At least <mark style="color:red;">two asset groups</mark> need to be added to the <mark style="color:red;">main track</mark> to enable \[Time Sequence Swap.]
* The original transition effects may be affected.

* During export, clips participated in swaps will be randomly recombined to increase the number of video variations.&#x20;
* The groups with Time Sequence Swap set may have their timeline positions swapped in the final combination result. For example, if A, B, and C are selected , there may be six possible results in terms of the order of resource groups on the main track: ABC/ACB/BAC/BCA/CAB/CBA.
* Time Sequence Swap can increase the number of videos in the final combination.

## <mark style="color:blue;">The difference between Swap & Time Sequence Swap</mark>

* Swap：The order of the asset group on the timeline is fixed, and only the materials within the asset group participate in the arrangement and combination.
* Time Sequence Swap：When turned on, not only the materials within the asset group will be combined, but the order of the asset group on the timeline will also be disrupted and reorganized, thus increasing the number of video combinations.
