PART TWO
2. The range of application
from VirtualCompose is divided into 3 different categories:
A. A Composing independently of objects of the background
video
B. A Composing dependent on objects on the background video
C A Composing of objects with partial dependency on the
background video
Under all 3 categories unikale scene cross fades or
2/3-dimensionale moving in RTS von Objekten can be created.
Particularly for three-dimensional Inserts functions of other
operators or Raytracer are included and combined with VirtualCompose.
We take a length for the background scene of 5 seconds for
all examples as basis. 5 seconds = 250 Fields (half-images) = 125
Frames (frames). " points " the positions of the object on the
background video are called. The points always correspond to the
focal point of the object. The whole of all points results in the
movement path.
During editing the path you should use the following cut
list:
1. Background scene
2. Background scene
3. VirtualCompose
Afterwards you replace the 1. Background scene with the
object scene. The simplest cut list can look then in such a way:
1. Object scene
2. Fast scaling (e.g..)
3. Background scene
4. VirtualCompose
A. Composing von Objekten independently of the background
video
For the Composing independently of objects of the background
video VirtualCompose makes directly several path Edit possibilities
available.
1.
In the window " Draw Settings " adjust you under " Edit mode
" the option " Path ". The entire path is then displayed during
editing. Select under " Draw Mode" >"Vector ". Activate " Korrel "
(" on ") and place " power " on e.g.. " 3 ". " Korrel " certainly to
what extent again set points dependent on the preceding are. Set the
1. Point. With that 2. You determine point the distance (in the
video is then the rate of the object) between the points 1, 2 and all
following. Under " Acceleration " you can change the distance (rate)
later. All following points can be set now by determination of a
direction (Vector), it is no matter how far the new point of the
preceding is placed - the direction is important. Ever after like is
largely the correlation value under " power " set, the new point will
correspond to the focused direction. This method is particularly
recommended for the fast creation of flowing movements, since the
points harmonieren among themselves always. A rework of the path is
omitted.
2.
Operate in the " operator " window " DELETE ALL ". Issue
under " D r a w M o d e"->"H a n d ". All points absolutely
independently are set (not correlated) from each other. Ansich is so
only conditionally usable this method, since movements take place
jerkily. This type of editing gets a deeper sense only with the
virtual INSERT. Usable is this method however nevertheless:
3.
Operate in the " operator " window " DELETE ALL ". Set now
e.g. only 5 points - into all of the 4 Frameecken and one into the
center. Press now in " operator " window the key " Stretch len ". VC
interpolates the distances between the points with intermediate
points, whereby the first by hand set point corresponds first of the
path and the 5th set point the latter, in our example 250..
4.
Now if the corners of the path are to be smoothed, then "
Korrel " should be on " on ". Access with the mouse a corner point
and pull these in the direction opposite to the corner. As a function
of set " power " the value precipitates the attainable curvature. It
pay attention that sometimes all points are along-drawn (we to want
also further no Ruckler in the course of motion of the object to
have), which can lead to a Depositionierung of all points. Can to
that be worked against, by executing several times a setting and short
shifts.
With the " Stretch equ " key e.g. 5 the set points are
converted in such a way into a path that the distances are divided
into sections equal in size. The rate of the object is then alike on
all paragraph. After pressing this key however 1 to X points must be
set by hand to the end of the path, there it mathematically not
possibly are any distances into paragraph equal in size to be divided
and at the same time a pre-defined number of partitionings to be
obtained.
