1.
After you have launched Final Cut Pro import your asset into
the Browser. For my example it will be a bunch of balloons.
2.
Load your asset (clip) into the Timeline and then double click
on it to load the clip from the Timeline into the Viewer. When
you load a clip from the Timeline into the Viewer you are creating
a dynamic relationship between the two windows. Whatever you
do to a clip in one window happens in the other. The only difference
is that loading a clip into the Viewer only allows for modification
of that clip and not the rest of the timeline.
3.
It is important to make sure that you alter the view settings
inside of the Canvas window.
You may have Image + Wireframe selected.
Although it is not bad to have this selected, with certain filters
you cannot have this option active if you want to be able to
use the features of the filter. Go to the View button in the
Viewer. Change your selection to Image
4.
Go to the Effects tab in the Browser and open the Filters folder
(Click on the small triangle to the right of the folder.)
5.
Go to the folder labeled Colour Correction open it and then click
(hold) drag and drop the Colour Corrector onto the clip in the
Timeline or up into the Viewer.
6.
A new tab will appear in the Viewer call Color Corrector, click
on it to access the colour correction tools.
7.
Go to the Timeline and shift the Playhead to a new position on
the footage that you are using. Try to find a section that will
show the majority of the object that you want to sample colour
from.
8. Select
the Eye Dropper Tool in the Color Corrector Tab then go over
to the Canvas window and select a colour sample. For my example
I am going to choose the blue balloon in my cluster of balloons.
9.
You will notice that in the Limit Effect area a one colour (blue)
is prominent as it was the one that I originally select. What
we need to do now is set up the image so that we can choose subsequent
samples.
Go to the Saturation slider directly
above the Limit Effect area. Movie the slider all the way to
the left. You should see that the blue that was sampled now turns
gray.
10. Sample
another section of the balloon. Simply, click on the Eye Dropper
again. Hold the shift key when you go back to the Canvas window
to select another colour in the same object. You should see a
tiny plus symbol beside the eye dropper. This indicates that
you are going to add to the sample that you have taken earlier.
Click to select the additional sample. Repeat as necessary. You
will find that zooming into the object on the canvas window will
allow you to select colour samples in greater detail.
11. Click
on the key button in the Color Corrector window. This will change
what you are viewing to a black and white picture. This view
shows the mask you are creating. With this image in the Canvas
window, you can use the handles on the Saturation and Luma sections
of the Limit Effect Area to try and make the object completely
white. Essentially you are creating a mask.
Your objective is to mask the item completely,
it is important to make sure that you don't mask out too much.
How much is too much you say? Although this is effectively a
mask, you are not actually masking it to be placed over another
item. You are "masking" out the colour. If you mask
out everything you will also affecting the highlights and reflections
too. While your objective may be to mask the item completely,
it is important to make the effect more natural, you want to
leave some highlight and refection as its original colour.
12.
Click on the key button twice to bring it back to the desaturated
object image. (My Balloon is gray).
*The key changes colour for three
different views; Final, the default, shows the results of your
color key effect, Matte shows the area that you have selected
for your color key and Source shows the image with no color key
effect applied.
13.
Click on the invert button located under the key button, looks
like a roof of a house.
