Transitions are how each block moves into the next one. Your Video Style will apply transitions to the entire project rather than individual blocks, which means each type of block transition is consistent throughout the video. You’ll find those under the Video Settings tab in the Design Settings menu. After you select a Video Style you’ll see it applied to your video.
There are different types of transitions between different block types. For example, the transition between a photo block and a text block is different from the transition between a photo block and a photo block. Although you can’t select specific transitions for each block, using different block types will help you achieve a unique look and feel throughout your video!
