Once you have added multiple scenes to a video template you can add and customise the transitions between each scene. By default there will be no transitional effects, scenes will simply play seamlessly one after the other.
In this example containing three scenes, there will be two transitional points. Transition points are represented by the small circle within a scene preview or between two scene previews in the timeline, one of which is pointed out by the green arrow above.
To add/change transitions you will need to open the transitions panel on the right hand side of the workspace:
To add or change a transition you can either:
Click on the transition point in the timeline that you want to work on. Once selected you can then select one of the pre-built transitions and it will be applied.
Drag your preferred transition from the Transitions panel and hold it over the transition point where you want to apply it and then release the mouse.
Once a transition is in place and selected you will see a black box as shown below. You can drag either edge of the box to modify the length of the transition, i.e. when it begins and then completes its effect. You can zoom in on the timeline if you want to control this with more granularity.
