Before you start creating your animation, there are three quick decisions to set the foundation for your project: how long your scene runs, what size it fills, and what sits behind it all.
Set your scene duration
This defines the length of your animation and export output. The default length is 4 seconds and the max is 120 seconds. Choose a length that suits your project by dragging the the grey marker in the timeline left or right.
Choose your artboard dimensions
Define this early on to match your target format. That might be a social square, widescreen video, vertical story, or something else. Open the Format dropdown menu to choose predefined dimensions, or set your dimensions manually in the Size property.
Set your background
Choose a solid color or gradient, or drop in a media asset to set your canvas background. Uncheck the background Fill property if you need a transparent background on export (only available on the Max plan).
✏️ Note: your background fill travels with your artboard when you turn it into an animated component, so setting it right at the start saves you from chasing consistency later.
