Quick Guide To Building A Composite; Setting The Foreground Backing Color - Blackmagic Design Ultimatte 12 Manual De Operaciones

Quick Guide to Building a Composite

This is a basic introduction to performing a fast composite. You will notice while reading this
section that occasionally a feature will be specific to a particular Ultimatte model.
With all sources connected to the main unit, the first step is to make sure the backing color is
correctly set. The default backing color is green, but you can set it to red or blue, depending on
which color you are using on set.
If you are using a green screen, you don't need to change the backing color as green is already
set by default. Clicking the 'auto key' button will perform an automatic composite and generate
a matte from your green screen.
TIP An automatic composite will also take place when power cycling your Ultimatte.

Setting the Foreground Backing Color

The backing color defines the color Ultimatte will use to generate the matte. Typically, the color
used for most screens for compositing is green, and this is why green is the default backing
color. However, there are occasions on set where red or blue may be a better choice based on
the color of the foreground objects. In this event, you will need to tell Ultimatte to use a different
backing color.
To set the backing color:
1 Click the 'settings' menu button to open the settings.
2 In the functions section, choose the red, green or blue backing buttons to select your
desired backing color. You will now see the backing color indicator in the status bar
change to the corresponding backing color.
Select a red, green or blue backing color from the functions area.
When the backing color is set, Ultimatte will perform an automatic composite and you will
see the results on the program output and Ultimatte's front panel LCD. In the monitor output
area, select the program output and the image will appear on the monitor connected to the
monitor output.
