Curve example
With the trajectory types and the associated adjustment options, the user can
change the course of movements between the keyframes of a timeline. This can
be clearly seen when the timeline changes the wipe position. The trajectory set-
tings are stored automatically when
– a keyframe is entered in Learn
– an actual keyframe is inserted or changed in Edit.
Each keyframe may have a different trajectory setting which describes the transi-
tion to the next keyframe.
The trajectory controls TENS, BIAS, CONTI, WEIGHT are adjusted with the digi-
pots. The function keys below the respective bars can be used to set the value to
”50%” which is indicated with an arrow. The different trajectory types are selected
with the function key or with the mouse (DD10) below the indication. The following
trajectory types are available:
LINEAR Produces a linear movement at constant speed between the key-
frames and sudden changes in the direction of movement and in
the speed of keyframe.
S-CURV Produces a straight–line course of movements. The speed starts
at 0, rises to maximum and falls again to 0. The direction changes
with the keyframes.
SMOOTH Produces a smooth even movement avoiding sudden changes in
direction and speed. This makes the movement appear ”natural”.
The controls TENS, BIAS, CONTI, WEIGHT are only effective for
Smooth Trajectory.
