3 Select the second channel to swap.
4 From the Curve Functions box in the Keyframe tab, select Swap.
The selected channel is swapped with the channel in the clipboard.
5 Select the first channel and click Paste.
The two channels are swapped.
Flipping Channels and Keyframes
Select Negate in the Curve Functions box to flip a channel or a group of keyframes vertically. Select Reverse
to flip a channel or a group of keyframes horizontally. Typically, you reverse or flip keyframes so that you
can create symmetry with an animation. For example, use Reverse on an image that is warping from a sphere
to a flat plane so that it then goes from a flat plane back to a sphere again. Perform these functions in the
Animation Curve window.
To negate or reverse a channel or group of keyframes:
1 In the Animation Channel Editor, select a channel or group of keyframes.
2 From the Curve Functions box in the Keyframe tab, select Negate or Reverse.
The selection is flipped horizontally (negate) or vertically (reverse).
Removing Jitter from an Animation Curve
Select Jitter in the Curve Functions box to remove jitter from an animation curve or within a group of
keyframes. Use the Curve Value field to specify the Over value. As a general rule, start with a large Over
value over n frames to remove slow jitter, and a small Over value to remove fast jitter. The Jitter option is
typically used on shift data in the Stabilizer to remove jitter while keeping camera movement. See
Removing
Jitter While Keeping Overall Motion
(page 728).
To remove jitter:
1 Select a channel or group of keyframes.
2 In the Curve Functions box in the Keyframe tab, select Jitter.
3 In the Curve Value field, specify the Over value.
Applying an Average
Select Average in the Curve Functions box to remove jitter from a jittery animation track. While the Jitter
option is used for removing jitter caused by trackers in the Stabilizer, the Average option is used to remove
jitter from an animation track. Enter the number of keyframes used to calculate the average in the Curve
Value field.
You can change the timing of a motion path animation without changing the motion path spline by adding
a keyframe to the speed curve.
To average a channel:
1 Select a channel or group of keyframes.
2 In the Curve Functions box in the Keyframe tab, select Average.
