Extracting performers

The extraction process "subtracts" the background identified in step 1, from the corresponding video of the performer. Choose which performer(s) to extract from their background by selecting the extract option found under each image.
The choice you make depends on which background you wish to remove. If only one background clip was loaded in step 1, this must be the background extracted here in step 3. Your three choices are:

1.	Extract left - the extracted performers will be blended on the background of the right hand clip.

2.	Extract right - the performers will be blended on the background of the left hand clip.

3.	Extract both - if both performers are extracted it is possible to make a choice of which background to use in the next step.
