Make background's matte perfect black
The first step is to select if you are using green or blue background by clicking on larger Background Color
rectangle.
Next goal it to get perfect black background's matte in matte view.
To toggle matte view user need to click Matte View checkbox over the output preview.
Example of matte view with neutral values
To do this the best way is to use Black Level, and in harder cases, (i.e. when edge of the anchor is getting too
sharp) Tolerance. In most cases to achieve proper matte (black) for the background the first of two sliders
mentioned above is enough.
Matte view after changing neutral values to get black background's matte.
(Black level-180)
Although on the shown example the Black level was enough it is not the rule that it has to be like that. There are
plenty of conditions like the quality of paint, lights settings, camera, anchors clothes, etc. which affects on keying and
so on its parameters.

Making anchor's matte solid white
There are some scenarios when after step 1 anchor's matte is not solid white. Use White Level to correct this.
Example of situation where we have perfect black background's matte but not solid anchor's matte.
To help this move White Level slider to lower position.
Of course if the colour on anchor will be too similar to the background colour, probably even White Level slider won't
help because it will cause the background to be also visible again.
The idea of this step is to try to get solid anchor's matte without losing perfect black on the background.
If it proved to be impossible then the last chance is to work with Tolerance sliders.
Now we solid white anchor's matte and have perfect black background's matte.
The main rule on working with sliders is to get the best results with moving it as less as possible. So if user is able to
achieve solid anchor's matte on different ways, the one with the lowest slider's movement should be chosen
