Automatic Selecting and
Scripting for Efficiency in
Compositing
When compositing movies, it takes a
long time to generate selections and
paint in the background for each
frame. Scripting can make this much
easier and faster. For information
about recording scripts, refer to
“Scripting” on page 415.
You can create a selection based on
image characteristics or color. You do
this once and record the process as a
script. You can then apply the script to
all frames in your movie. For
information about creating selections
based on image characteristics, refer to
“Creating an Auto Selection” on
page 208. For information about
creating selections based on color,
refer to “Selecting By Color” on
page 209.
To use Scripting and Auto Select
to create a movie:
1 Work with a separate, sample
image to determine whether Auto
Select or Color Select works best
with your image.
2 When you’ve determined the
settings for the best method, start
over. This time, record the Auto
Select or Color Select process as a
script. When you’ve finished
creating the selection, stop
recording. Save the script.
3 Open the frame stack you wish to
create selections in.
4 Choose Movie menu > Apply
Script to Movie.
5 In the dialog box, select the Auto
Select or Color Select script you
saved.
Corel Painter applies the script to
each frame in the stack.
Cloning a Movie
Cloning from one movie to another is
almost like cloning from one image to
another. The only difference is that
you are cloning from one sequence of
frames to another sequence of frames.
In this case, by advancing one frame
in the clone frame stack, Corel Painter
automatically advances one frame in
the source frame stack.
When you set a movie clone source,
the current frame in the clone is
matched to the current frame in the
source. If both movies are rewound to
frame 1, the clone-to-source
correspondence is 1-1, 2-2, 3-3. This
means that the source for frame 1 in
the clone movie is frame 1 in the
source movie, and so on. If you like,
