You can add animations to any element you add to your project, like images or blocks of text. Click on the element you want to animate, then click on the "Animate" option that appears in the menu along the top of the screen. Elements can be animated as they enter the screen, exit, or both.
You may want elements like specific images or text to appear and disappear from your screen at specific times.
To edit the timing of a specific element, click on it, then click on the three dots ("more") that appear in the pop-up menu bar. Select "Show element timing" from the menu that appears.
You will now be able to see each element and its timing as a purple bar. You can change the duration of an element by dragging on the beginning or end of this bar. You can make the timing element workspace bigger using the zoom feature in the lower right corner of your screen.
Animaker is an online app that allows you to create animations that can be downloaded shared through link. The free version allows you to create 2 customizable characters.
