The active time segment specifies a block of working time. You might think of it as a window in time that you use to focus
on a specific part of your animation.
Specifying an Active Time Segment
You specify the active time segment by setting the Start Time and End Time for the segment on the Time Configuration dialog.
You can change the active time segment whenever you want without affecting the keys you've already created. For example, if
you have keys scattered over a range of 1000 frames, you can narrow your active time segment to work only on frames 150-300.
Changing the active time segment has the following effect:
- Restricts the range of time you can access using the time slider.
- Restricts the range of time displayed when using the animation playback buttons.
The default setting for the active time segment runs from frames 0 to 100, but you can set it to any range.
You can also increase the active time segment using the track bar.
Rescaling the Active Time Segment
You use the Re-scale Time button on the Time Configuration dialog to change your entire animation based on the active time segment.
Use Re-scale Time as follows:
- Scale all animation in the active time segment to fit within a new time range.
- Move the entire animation to a new time.
Click Re-scale Time and then enter new Start Time and End Time values on the Re-scale Time dialog. When you click OK all the
animation in the active time segment is moved and scaled to fit the new Start Time and End Time settings. Any animation outside
the active time segment is moved to match the new active time segment boundaries.
For example, say you have an animation from frame 0 to frame 300 and an active time segment starting at frame 100 and ending
at frame 200. Use Re-scale Time to set the new Start Time to frame 200 and the new End Time to frame 250. Clicking OK gives
you the following result:
- Animation in the active time segment moves forward 100 frames and shrinks to a length of 50 frames. The new active time segment
is from frames 200 to 250.
- Animation in the frames preceding the original active time segment moves forward 100 frames to connect to the start of the
new active time segment.
- Animation in the 100 frames after the original active time segment moves forward 50 frames to connect to the end of the new
active time segment.
You can also rescale the active time segment using the track bar.
