Animation basics
An overview of some key concepts involved with animation.Animating an object means changing one or more characteristics or attributes of the object over time. An object generally has many attributes, or animation parameters, that can be animated. In AliasStudio, you can animate objects as well as lights, cameras, and shaders to create animated sequences.
> Frames and Keyframes
The basic unit of measurement for all animations is the frame. For a typical animation, you set a specific number of frames per second, which determines the timing of the motion and the length of the animation in frames. Typically, video is set at 30 frames per second and films are set at 24 frames per second.
To animate any object, light, camera or shader, you must set keyframes. Keyframes are frames that specify the parameters of an item at specific points in time. After you have set two keyframes, AliasStudio interpolates the action for the frames between the keyframes. This is very similar to how a traditional cel animator works. A senior animator (you) creates and sets the key poses for your objects and characters, then passes them to a junior animator (AliasStudio) who draws the "in-between" frames.
> The Time Slider
In order to play the animation, you'll use the time slider. When enabled, the time slider appears in the interface just below the AliasStudio menu and layer bar. Enable the time slider by choosing the Animation > Show > Toggle time slider menu item.
At the right end of the time slider are icons similar to those on a VCR or DVD player that let you play, stop, rewind, or fast-forward an animation. Above the controls are fields that show the current frame and frames per second.
In the center of the time slider is the scrub bar containing a series of ruler-marks and numbers that indicate the individual frames of the animation. The current frame is indicated by the gray rectangle, or frame indicator, that moves along the scrub bar.
At the left end of the time slider are input fields that allow you to set the range of frames to be displayed in the scrub bar.
