An additional path point is positioned when you
click on Insert. The newly inserted path point
is the active path point, displayed in green.
Inactive points are yellow. The new point is
always inserted in back of the currently active
path point. If the active path point is not the
last one, then it is inserted exactly between the
current and the next path point on the curve (of
course, two path points define a line segment,
not a curve).
Note: A path-point segment consists of two to
ten path points together, whereby the path point
for the full display time is always displayed as
a large octagon. The drawing moves at steady
velocity from the first to the last path point of
the curve. If two path points are near to each
other, then the drawing is on the corresponding
curve segment for a shorter time then when the
two points are further apart from each other.
(You should remember this note when you want
to change certain values of the drawing between
path points.)
If two path points exist and one path point lies
exactly on top of the other, then the drawing
does not move. But parameters of the drawing
can still be modified and take effect for the entire
fade time. For example, a fade can be created
at that point. If there are more that two path
points, and one point lies exactly on top of its
neighboring path point, then the first point has
no duration and is skipped.
Clicking on the Delete button removes the
currently active path point so that the previous
path point becomes the currently active path
point.
Clicking on the Position button causes the active
path point to turn blue. It can now be moved
with the trackball. During this process you can
view the position coordinates at the screen
edges. You confirm the new position with the
left trackball button, or cancel with the right
button.
The Position button does not necessarily have to
be used. You can click directly on an active path
point once or on a non-active path point twice
(to make it active) and then drag the path point.
If you would like to put the point outside of the
video frame, then simply by dragging the point
out of the frame causes a representation of the
relevant region beyond the visible surface to
become visible.
The meaning of the path-point colors is
summarized below:
Note: “Interpolation” means the automatic
calculation of values between given control
points.
yellow: a non-active control point without
particular characteristics. Clicking on the point
causes it to turn green (active).
red: a non-active control point for which settings
have been made manually under Edit. This
means that at least one checkmark was set
manually (no interpolation). Clicking on the
point causes it to turn green.
green: the currently active point. The operations
Position, Edit and Delete refer to this point.
Clicking on the point causes it to turn blue.
blue: This point can be dragged to a new
position. After being clicked again the point
turns green.
When you click on Edit, a window appears in
which you can specify the size and the alpha
value of the active path point.
If you click on Size, the window disappears
and the path point becomes active so that its
size can be changed. The size is displayed at
the screen edge. A click on Alpha activates the
slider bar to the side, with which you can set the
transparency value of the drawing between 0
and 100%.
You can disable the buttons Size and Alpha by
clicking on the corresponding check boxes so
