About Time Domains
There are three variables to set when creating an animation:
Frame count––the number of frames in the animation
Frame rate—the interval after which the frame changes to the next one
Animation length/end time—the total duration (in seconds) of the animation
When you select a time domain and enter values for two of the variables in the Animation Time Domain dialog box, the value of the third variable is automatically calculated.
For a Length and rate time domain, enter the animation length (in seconds) and the frame rate or interval (the number of frames per second). The total number of frames is automatically calculated.
For a Length and frame count time domain, enter the animation length (in seconds) and the total number of frames. The frame rate is automatically calculated.
For a Rate and frame count time domain, enter the total frame count and the animation frame rate or interval. The animation length is automatically calculated.
