You can enter positive or negative values in any spinner, but you must use the same format used by the time display. You can change the active time segment without affecting the keys you've created. For example, if you have keys scattered over a range of 1000 frames, you can narrow your active time segment to work on only frames 150 to 300. You can only work on the 150 frames in the active segment, but the remainder of the animation stays intact. Returning the active segment from 0 to 1000 restores access and playback of all the keys. Changing the active time segment has the following effects: it restricts the range of time you can use with the time slider, and it 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. To stretch out your existing animation over a longer time: 1 In the Time Configuration dialog > Animation group, click Re-scale Time. 2 Change the value in Length to be the number of frames you want the action to fill. 3 Click OK. The animation is rescaled to the new number of frames. This also works to compress animations into a shorter space of time. To avoid losing frames during the rescaling, see "To use sub-frame animation" in this set of procedures. To add frames onto your existing animation: This procedure adds new frames to the end of your animation, without affecting your existing work. 1 In the Time Configuration dialog > Animation group > End Time field, enter the number of the last frame of the animation. For example, if your existing animation is 100 frames long and you want to add 50 frames, enter 150. 2 Click OK. The number you entered is now the new length of the animation, shown on the time slider. 7566 | Chapter 25 User Interface
