7.14 The Operator ’DeInterlace’
The operator ’DeInterlace’ enables you to convert interlaced material
(fields) on your system into the progressive image format (frames).
Figure 7-52: Deinterlace operator
This section describes in detail the settings provided by this operator.
The items available under the heading Mode determine the method
used for the deinterlacing:
If the deinterlace operator is used on a clip, it has to be preren-
dered prior to a play-out (see section “Prerendering of Timeline
Elements” on page 6-46).
Line_Duplication This mode simply duplicates in the images the
lines selected in the Even/Odd area, meaning
either the odd or the even lines of an interlaced
field will be doubled to get rid of the interlacing.
The method of doubling lines is most suited
when your clip contains no moving objects.
Line_Interpolation The effects of the line interpolation method are
almost identical to the ones of the line duplica-
tion. Every second line in the image is dropped
and replaced by an interpolation of neighboring
lines. Thus slow moving objects in your clip will
most likely be rendered with a good result be-
cause differences between two lines are calcu-
lated and averaged out.
