With the Random selection effect, you gather several contents, such as photos and videos or even Chapters and Flexi-Collages in one object. When playing, however, only one track, for example, only one photo or video, is randomly selected from the effect for playback.

You can find the effect in the Toolbox under the Objects tab in the Object effects section.

Drag the Random selection effect from the Toolbox to the Timeline. In the Timeline you will now see a colored box. Insert your images or videos here. Fetch the image or video e.g. via the Toolbox- tab Files into the Timeline or drag an image object or video object into the random selection effect to insert images or videos.

In the Random selection effect, the contents are automatically arranged one below the other.

During playback, only one track is randomly selected and its contents are played back. All other contents of the effect are not played.
At each playback, randomness decides again.

After you have inserted the images or videos, click on the colored frame of the Random selection in the Timeline.

In the Properties section you can now see the adjacent properties.

If the Random value field is set to Automatic, the system will decide which track to show each time it is played.
With the dice symbol you can also create a code that fixes the playback with the diced value. This selection is then retained for each playback.
