You will see the editor timeline; click on the Tag you want to add Ken Burns to and head to “Edit Tag Properties”. Click on Ken Burns and turn on Switch to activate it. You can change the Directions and zoom effect according to your preference.
If you want to add Ken Burns to all the tags present in your video, make sure to click on “Apply the same transition and Ken Burns to all the tags in this track.”
Click on Save, and That’s it. You have your Ken Burns applied all over your video.
