The program’s project window displays all of the layers in the project. In general, layers are grouped into two categories: clip layers (which contain a selection of frames of a clip) and composition layers (which are applied to the entire composition, making them appear in every frame). Adobe After effects CS6 also includes two types of keyframes that are used to maintain layers while changing a clip’s speed, rotation, position or other attributes: Selective keyframes, which are applied only to the selected frame; and Global keyframes, which are applied globally to all of the frames in the project. Layers and keyframes are also organized into groups, such as layers that are grouped by subject, and keyframes that can be applied to groups of layers.
The Keyframe Attributes window allows you to control the effects of keyframes, including how the effects of the keyframe are controlled by the clip’s speed, rotation, or position. You can also set global keyframes on layers.
In the Color Effect section, you can control the colors in the project, including individual color channels. In addition to controlling the colors in the project, you can also convert gradients, drop shadows, and other similar effects to be controlled by the project’s color settings. 827ec27edc
