Sphere01\Angle is an Angle parameter applied to one of the modifiers assigned
to a sphere. You can rename the tracks in the Properties dialog, which you
can access in Track View, or by double-clicking the track name in the Motion
Capture utility. The upper rollout of each Properties dialog includes a Track
Name field. Any name entered in the Track Name field appears in the Track
list in the command panel, in the title bar of the Properties dialog, and beside
the Data track in the Hierarchy list in Track View.
Record Range group
Specifies the frame range affected by the recording. You can also set a preroll
range of frames (see below).
Preroll Specifies the frame number where the animation begins playing when
you press the Start button. If this number is the same or greater than the In
number, the Preroll number is ignored. For example, if In: 0 and Out: 200,
then a Preroll of -100 would give you 100 frames before the recording started,
while a Preroll of 50 would be meaningless. If the range defined by Preroll
and Out is larger than the current segment, the segment is temporarily enlarged
during the recording.
In Specifies the frame number where the recording begins after you click Start.
Out Specifies the frame number where the recording ends after you click Start.
You can stop the recording before this by clicking Stop.
Live During Preroll When this is active, the motion capture is live through
the preroll frames. The motion occurs, but isn't recorded. This can cause sudden
motion shifts at the In frame because your live motion might not match the
animation when you reach the In frame. When this option is inactive, the
motion is disabled or frozen until you reach the In frame.
