Like the other effects in the pixel effects category the 'LUMA KEY' has several check boxes
that allow you to extract specific pixels from your image in order make them transparent.
By default the 'LUMA KEY' is set to the 'LUMA K.' check box. This removes all of the black
pixels from the image. By clicking on 'LUMA K. INV.' the filter will remove all the pixels
leaving only the black pixels in the image.
Also inside the 'LUMA KEY' filter are three check boxes labeled 'R' for red, 'G' for green
and 'B' for blue. When one of these boxes are selected it will remove that specific color from
the image. Try this yourself by using the ‘04_colors’ graphic to see
the results of making a particular color transparent.
Note
You may only select one checkbox
when using the ‘LUMA KEY’ filter.
How to apply the ‘NOISE’ effect
1
HOT TIP
When using a still image in a combination with
the ‘NOISE’ effect you will notice that the image
remains static. By using a movie clip and applying
the ‘NOISE’ effect you can create an active
background texture.

Move your mouse cursor over the thumbnail in the ‘MEDIA SET’ window labeled
‘04_colors’ and click on it or press the ‘4’ key on your keyboard.
Move your mouse cursor above the blue strip labeled ‘BLUR’ and click once
to activate the effect. The blue strip changes to orange indicating that the function
is active.
Move your mouse cursor downward and over the knob associated with the effect.
Click and drag to rotate the knob. Rotating the knob to the left decreases the blur
and rotating the knob to the right increases it.
Besides the knob the blur effect contains two check boxes: ‘FAST X’ and ‘BOX.’
The default options of the blur effect is set to the ‘BOX.’
What are the differences between the two? ‘FAST X’ only blurs the image in the layer
horizontally (from left to right). ‘BOX’ blurs the image in the layer horizontally and
vertically.
Using the animation effects
Below the ‘PIXEL FX’ panel is the ‘ANIMATION FX’
panel. ‘ANIMATION FX’ are time based functions that
allow you to create repetative and dynamic activity in
your composition. With traditional animation programs
you need to create the animation and then render a
movie file. This means that you can no longer control
the movement of a graphic element. With ‘ANIMATION
FX’ you can use a simple still image and change the way
the graphic animates whenever you want to. There are four animation effects:
HOT TIP
‘BOX’ blurring can be very demanding. If you have a simple composition
using ‘BOX’ should be fine. However
if you have a very complex composition using many layers using ‘BOX’
may cause Modul8 so slow down.
If this is the case try using ‘FAST X’
instead.
