Tweening Motion or Maintaining Values
Boom Studio can automatically generate inbetween drawings when
you move, scale, rotate or skew elements with pegs. This process
of generating inbetween transition drawings is known as
interpolation or motion tweening.
default, when you add keyframes to pegs, Toon Boom Studio tweens
the drawings animated by the peg. You can use a preference
setting to change the default keyframe/tweening
behavior of pegs. This setting is located on the scene planning
tab of preferences. You can set the default value to constant or
may not want to use interpolation to control the animation. To
do this, you must change a segment between two keyframes from a
tweened segment to a constant segment. When you create constant
segments, images switch from one to the other without any
tween the images between two keyframes you must change the
segment from a constant segment to a non-constant (tweened)
segment. When you tween images on a motion path, tick marks
appear on the motion path to indicate each position of the image
as it is interpolated.
can switch segments between constant and non-constant using menu
commands or the Function Editor.
Keyframes, on a peg, lock to a specific frame a change in
position, angle or scale .
To add a motion, rotation and scaling keyframe:
a Peg element in the Timeline window.
the frame you want to add the keyframe
Element > Peg > Add Keyframe.
Depending on the tool you have selected (Select, Motion, Rotate
or Scale), keyframes appear on the selected frame.
The tool you have selected
determines what kind of keyframe you create.
creates a keyframe for motion, scale, rotation and skew
Motion: creates a
keyframe for the position values.
a keyframe for the angle values.
Skew: creates a
keyframe for the skew values.
Scale: creates a
keyframe for the horizontal and
vertical scale values.
Marks in the Timeline identify keyframes for
motion, rotation, skewing or scaling.
Copying and Pasting Keyframes
You can copy and paste the
values of a keyframe to another keyframe. The values you copy
and paste depend on the tool you have selected.
copies/pastes the motion, scale, rotation and skew values.
copies/pastes only the position values.
copies/pastes only the horizontal and vertical scale
copies/pastes only the angle values.
copies/pastes only the skew values.
To copy and paste keyframe
1. In the Timeline
window, select the peg element.
2. Then, use the red frame
slider to select the frame whose values you want to copy.
3. From the Tools
menu, select the tool whose values you want to copy.
4. Select Edit > Copy
Cell to copy the values of the frame.
5. In the Timeline
window, use the red frame slider to select the frame where you
want to paste the copied values.
6. Select Edit > Paste
Cell to paste the values to the frame. The Toon Boom Studio
creates a keyframe if one does not already exist.
You can also use the Paste
Special command to copy selected values from the original
keyframe (including tension, continuity, bias, rotation, scale
and pivot) to another keyframe. You can even copy values from a
control point, which is a motion point that is not locked to a
specific frame, to another control point or keyframe.
To remove keyframe values:
Use the Remove Keyframe
command to delete the selected keyframe from the peg. Use the
Function Editor if you want to remove the velocity and pivot
data from the frame.
