The Project panel allows you to specify project level properties such as stage dimensions and frame rate.
It also allows you to tag meta information to the project, such as author and company.
Stage Size defines the dimension that will be used to fit the content to the target viewport. The values (width and height) will affect how the content is rendered depending on the stage scale-mode in use:
No Scale
This scale-mode renders the content without any scaling. The content will clip if the target viewport is smaller, and the content will not span the viewport if the target viewport is bigger.
Exact Fit
This scale-mode renders the content by stretching the content to fit the target viewport. This will cause the content to distort if the target viewport dimensions do not match the stage dimensions.
Show All (default) and No Border
These scale-modes will render the content by scaling the content while maintaining the content's aspect ratio.
Example: The target viewport is 1600x1200 (4:3 aspect ratio), and the stage dimensions are set to 1280x720 (16:9 aspect ratio).
Show All - The content will be scaled to fit inside the target viewport. The content will be scaled by using the 1280 dimension, and the result is empty space on the top and bottom.
No Border - The content will be scaled to cover the target viewport. The content will be scaled by using the 720 dimension, and the result is letterboxing; the sides of the content will be cutoff.
The Frames per Second (FPS) value defines the frame rate at which the content is advanced. Timelines will advance their playheads at this rate.
The Boot Scene allows you to set a scene that is initially loaded when opening the project.
The Boot Script field allows you to load a script for the project which is run before any scenes are loaded. This allows you to initialize values before scenes load.
The Preview field allows you to load a preview image for the project.
