Set Roto-Screen Correction

QUICK START

Under some circumstances, it may be difﬁcult to completely cover the screen area with the overlay. This

does not mean that the screen will not be removed in that area, but that other controls may need to be adjusted

to help reduce anomalies in those areas that were not covered by the overlay. It may be advantageous to re-

sample the screen using the Sample Backing tool found under the Screen Automation pop-up menu in the area

where covering the screen with the overlay is unsuccessful, but be careful about selecting in shadow areas if

the ﬁnal composite requires the retention of shadows.

Additionally, it may be difﬁcult in some circumstances to remove the overlay from very dark areas of

foreground detail that may be close to values in dark or shadow areas of the screen. If the overlay does include

some dark foreground areas, these areas may be recovered by enabling the Shadow controls.

Note: Since the AdvantEdge software is producing a synthetic clean plate using an interpolation process, it is

important to exclude non-video areas of the image, such as the black blanking lines that may appear in video or

the black areas in "letterbox" images. The guides should be used to exclude these areas from the overlay and

ﬁnal composites. Otherwise the synthetic clean plate may contain black (or other colors) which can result in an

inaccurate clean plate being generated.

Guides have been moved

in from the frame edges to

exclude unwanted portions.
