Tip:
  • The default behavior is continuous recording, but the recording will stop automatically if the playback option is set to Once rather than Loop.

Playback
Select whether to play the animation on a continuous Loop, Once, or Bounce (between forwards and backwards). Select the check box to Reverse Playback.
Display
Set the units for the slider to either Time or Frame.
Increment By
Increase the value in the counter to skip frames during playback. The reset button restores the default value of 1.
Speed
Drag the slider to change the speed of the animation.
Range
Select the Range checkbox to define and starting and ending frame for the animation. This allows you to limit the playback range to just a portion of the animation, making it easier to study behaviors in more detail. You can use the Ctrl key while clicking on the Start or End icons to jump to Range Start and Range End, respectively.
Note: For motion models, you can fit plots for the selected range by using the Ctrl key while double-clicking. Also, the paths of tracers will be trimmed to honor the specified range.
Scale Factor
Enter a custom value to change the scale of the animation. Generally the scale of a displacement is too small to see clearly, so auto scaling is enabled by default.
Recording Settings
The default Auto setting gives you an estimate of the duration of the recording at 30 frames per second. If your video plays back faster than you want, select Custom Duration to change the length of the video; this will adjust the frame rate to try to achieve the specified duration. The Custom Duration has a minimum value of 1 second, and maximum value of 30 seconds.
