The CremaTTe® algorithm was developed by Analog Way to perform a high quality keying. If your live source
contains some transparent area or if you need to key a dicult video of people with wispy hair, you need to
use CremaTTe® algorithm.
Using the CremaTTe® algorithm, we advise you to start by using the keying assistant.
Start to remove the main color using the white square in the keying assistant.

me on buon.

garbage on the screen.

the edge smoothing sengs allow you to determinate some area where you want to
add transparency. Adjusng the H S L values will display some around the edge of your live
content. Those will later be rendered semi-transparent.
Adjust accurately the HSL in order to make transparent only the desired area. (A too high level will make
transparent some solid area).
At this point, disable the mask and return to you original live
image.
