The selected clip highlights in yellow.
2 From the Trax menu, select View > Graph Anim Curves.
The Graph Editor appears.
3 In the Graph Editor, shift-select the two keys on the animation curve as
shown below.
4 In the Graph Editor, select Tangents > Flat.
The shape of the animation curve updates to a gentle S-shape. Setting
the tangents for the animation curve in this manner modifies the clip’s
animation to cause the aircraft to accelerate when it first rises, and
decelerate when it nears the end of its vertical travel.
5 Repeat steps 1 through 4 to set the animation curve tangents in a similar
manner for the two remaining clips: Travel_Forward and Aircraft_Lower.
The shape of the animation curve for Aircraft_Lower will be reversed from
the other clip curves because the motion is occurring in the opposite
direction.
6 Close the Graph Editor window.
7 Set the Time Slider’s current time indicator to frame 1.
8 Click play on the Time Slider’s playback control to play back the
animation.
The motion accelerates and decelerates at the beginning and end of each
clip. As a result, the motion appears more natural. It’s important to note
that the modified tangents for each clip are independent from the other
animation clips and do not affect any other motion.
9 Click stop on the Time Slider’s playback control.
