The only limitation with this app is that there is only one animation style. So if you need to rearrange the lines, you can just drag the dialogue cards and reorder them.
What makes this Plotagon app convenient is that each line is represented by a separate card. In inserting dialogues, you can either type their lines and have it spoken by the preset voice that comes with the character or you can lend your own voice through a recorded dialogue. There are main characters, whose dialogues you can edit, and extras. After the background, you can start inserting characters from the app’s wide range of preset character designs into your scene. Then, you will be given the option to choose from over 200 backgrounds.
When you start Plotagon Story, you will be asked to start a new project by adding a scene through the movie clapper icon.
