Transitions control how your media moves in and out of view whether it's from one block to the next or between images and videos within a block. 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 can also change the transition of your Media Frames, which will dictate how each image transitions into the block.
Transitions between blocks
Block transitions control how one block moves into the next and are set by your Video Style. Your Video Style also contains the pre-set Media Frames that will appear in the Layouts menu when you add a block. You'll find all of our Video Styles in the Video Settings menu under the Design tab at the top of your Workspace.
Media Frame Transitions
Media frame transitions let you control how each image or video moves within a block. To change one just click the image icon on the left side of the block to open the media panel. In the top right corner of each image or video you’ll see the name of the current transition. Click it and you’ll get a dropdown with other styles you can switch to.
