Scale keys

You can scale keys to change the duration of a range of keys and animation curve segments.

To scale keys

1. Set the Scale Keys options. See Set Scale Keys options.
   Tip

   • You can cut the duration of a range of animation in half using the Time Scale/Pivot option.
   • To scale the animation without affecting the curves of the animation before and after this range, select the Scale/Pivot Method.

   Keys and animation curve segments adjacent to the scaled region will be shifted in time by the amount the scaled range has been compressed or expanded, but their shapes are be preserved.
2. Do one of the following:
   • To select a single key, click the key in the Time Slider.

   The Current Time Indicator moves to the clicked position and the key is now selected.

   • To select multiple keys, -drag over the range of keys in the Time Slider.

   The range of keys is now selected and highlighted in red.

3. Select Edit > Keys > Scale Keys.

   If Time Range-All is on in the Scale Keys Options, all keys for the current object are scaled.

   If Time Range-Start/End is on in the Scale Keys Options, only keys between the specified Start and End times are scaled.

   If Time Range-Time Slider is on in the Scale Keys Options, only the keys between the Range Slider’s Start and End times are scaled.
