|This tutorial shows how to
composite a video clip with blue screen and another clip. In this
example, a running man animation of 30 frames was created in Poser 5, the popular human figure
art creation tool from e-Frontier/Curiouslabs.
The figure is rendered against a blue background. This will simulate
real-world video of actual persons filmed in front of a blue screen.
PD Pro has the ability to create compositions of such video clips with
other clips, and use the blue pixels as a means to identify transparent
areas so that the other clip will show there instead. The running man
will then appear to be running in front of the other clip.
||There are other techniques
available too, such as greenscreen, or
keying against any color, or using the alpha channel if it contains an
We will need a second clip
for this exercise. It could be from a video camera, or something
created elsewhere. In this example, we use PD Pro itself. We started
with a Plasm Noise (HSV mode) and applied a special sharpening tool.
(Art sharpen) to also reduce the number of colors.
||A color sobel edge filter
was then used, turned to greyscale, and the
Value filter used to adjust contrast. This creates a nice set of black
on white outlines.
The edges were then merged
over the colored version, creating this look. Am animation was then
created, containing 60 frames.
||Additional filters were
applied, such as Mystic vision, Light diffusion
and fish eye.
This ends up being the animation we'll use as the background.

you will need to
convert this to an image sequence in BMP format if you want to use it
for this exercise. (read below for details)

|And last but not least,
here's the result we're trying to achive: a composite of the running
man showing over the animated background.
Notice that the two animations are not of the same size or frame count.
The running man animation was rendered in Poser at 512x512 pixels
(square). It is made of 30 frames.
The background bg2 clip has 60 frames, and is 320x240 (non-square) in
shape. It needs to be available as a BMP image sequence. If you use the
example here (as an AVI file) you'll need to extract the frames to BMP.
PD Pro can save to image sequence in BMP. Or you can also use Irfanview
or other imaging tools.
