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.

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.
