Take X6 as an example, click the "Settings" menu and select the "Parameter Selection" command to pop up the dialog box, as shown in the figure.

Check "Automatically Add Transition Effect" in the "Transition Effect" column, and the transition effect will be set to the default "Random".

After confirmation, if you import pictures into the video track again, no matter how many you import, you will automatically add a transition effect in an instant, without adding them one by one, but there is a disadvantage that there is no personality. What kind of transition to add is entirely up to you.
