VirtualCompose, the attendant in the video space
- a Workshop for the Draconer of Felicitas book wood -
I. Basic to the work with VirtualCompose
By ' Composing ' the definition of the way of any objects in
the space represented by a video scene is understood here.
1. Functions of version 1.7
The version 1.7 of VirtualCompose really
surprised, better said me: run over! I waited even for the version
1.6, when the version 1.7 arrived. Mad concept of MLCO to send to
faithful Usern the updates free of charge and in addition still with
functions, about which we dared to only dream.
One of it calls itself SmartMove - too
German ' intelligent course ' - and easily by depressing the key is
activated. It puts titles, results of other operators (funnel, balls
etc.), one to any objects, like scenes, around the factor 255
increased motion travel at the disposal. If you adjusted PAL CCIR in
your project, then e.g. the horizontal dissolution amounts to exactly
688 points. If you now a scaled scene over the display induce in such
a way had this scene so far exactly these 688 points for the movement
to the order. SmartMove multiplies these 688 by 255 = 175440 points. One with VirtualCompose moved scene keeps thus made
available for your movement in horizontal direction 175440 points and
in vertical direction 142800 points. The movement is absolutely liquid, even if the scene crosses only very short
distances.
Thus it is now possible to move scenes (all
objects) in the video gently which particularly sets new yardsticks in
my Betacam and data processing contributions for advertising
productions!
Likewise meu the Glamour key was added. Glamour, charm, activates 2 functions: Aura and Fade. Introduce
yourselves, you must in your production a reduced scene over another
background scene run to let. Both scenes are quite similar in colour
and brightness. ' aura ' sets now a Glorienschein
around the reduced scene and lets these better become effective. In
addition, titles and all other objects can receive this aura. Colour
and size of the aura can adapt you to your needs. So that the Glamour
function knows, where the aura is to be set, the following is to be
considered: Glamour does not detect transitions of ' transparent '
too ' transparent '. If you create a trapezoid as example from a
scene, then is everywhere, where the changed scene is (thus in the
trapezoid), transparency equal zero. The remainder is transparent.
Thus Glamour knows that the aura is to be put there.
Simplest the always cut list can look now in such a way:
Scene (object)
Fast scaling
Background scene
VirtualCompose
(you do not forget to determine before the calculation a
path)
' Fade ' works exactly in reverse, i.e. it
emphasizes edges not, separates fades out these gently. Particularly
with virtual Inserts is good this function to use, since the pages of
the objects are not defined sharply any longer.
It requires special effort to send a title on a course. The
problem is situated in the fact that calling operators unfortunately
do not pass ' transparentnesses on '. If you want to set a title on a
scene, then you put simply e.g. to MonumentDesigner under the scene.
After the calculation the title is to be seen beautiful on the scene.
We want to send however the title on a course, which meant that only
the title obscurely, everything else be however transparent must, in
order to see the background scene, on the title moves. Here we must
draw the MASK operator.
Background (Alpha=255!!!, r, g, b=0)
MonumentDesigner or Titel2
MASK (r, g, b=0, Toleranz=0, Match=0, NoMatch=255)
Background scene
VirtualCompose
It becomes particularly interesting, if we want to add now
still another aura. The background (see above example) should
indicate the same farbeinstellungen after possibility (however not
Vorraussetzung), as the aura under VirtualCompose. Accordingly also
the MASK operator must have these farbeinstellungen, in order to
away-punch the background.
The function ' MotionBlur ' puts ' still
the crown to the moving objects ', by adding a movement tail. This
can be determined in the length and works in the background (or in the
foreground, if ' front ' is switched on) and smears the object. The
represented picture shows one with MonumentDesigner created writing on
a background (background operator with colour tone). VirtualCompose
with more switched on ' aura ' and ' MotionBlur ' with MotionStep=3
used unfortunately can a Browser picture the gentle-soft movement of
the writing in the video not show, which produces SmartMove.
By the way: By the possibility practically arbitrarily often
of using VirtualCompose in a project new fascinating possibilities of
moving in RTS are opened!.
