These controls determine default values for newly created projects. To change these
settings for a specific project, modify similar settings in the Project Properties dialog
(choose Edit > Project Properties or press Command-J).
Note: These settings only take effect in projects created after the preferences are set.
Any currently-opened projects are not affected.

into the value field and choose Frames or Seconds from the pop-up menu.

Note: To render a new background color into your final output, you must choose Solid
from the Background pop-up menu in the General tab of the Project Properties dialog
(press Command-J).
To change the background color:
m Click or Control-click the color well, then use the Colors window or pop-up color
palette to select a new color.
The selected color becomes the background color for subsequent projects.
