9.2.4 Define video settings
You can use the Nero Digital Video Settings dialog box to define the settings for the video
encoder.
9.2.4.1
Deinterlace tab
The following input option is available:
De-Interlace Video
area
Nero Recode automatically recognizes when a DVD video
title is made up of half frames (see interlaced).
If a video is interlaced, Nero Recode recommends de-
interlacing to increase Nero Digital image quality.
The Enable option converts the video title.
The Interlacing process, which is used to display a TV image in PAL standard, displays two
half frames in succession. As the frame is generated, only the odd lines from the output
device are displayed for the first half frame and, one this is complete, the second half frame
is generated from the even lines. The two frames are coded separately. The relatively high
refresh frequency means that the eye picks this up as a single frame.
Modern screens (e.g. LCD, Plasma, DLP) can only reproduce the Interlacing process with
a restricted image quality. For this reason, the half frames of videos can be converted into
full frames in the Nero Digital video settings.
9.2.4.2
Crop tab
If the DVD video has black borders on the sides, these can be automatically edited out. This
reduces the size of the video and thereby improves its quality. Nero Recode recognizes
these borders automatically and edits them out automatically.
The following input options area available:
Automatic radio
button
Detects black borders and edits these out. Default setting.
Custom Crop
radio button
Enables the four input fields for Crop (top, bottom, right, left)
and the Adjust button.
Adjust
button
Opens a dialog window and displays a frame from the video.
You can use the mouse to define the four cropping areas
(top, bottom, left, right) by hand. The button is only enabled
if the Custom Crop option is enabled.
Disable
radio button
Allows the video to be converted without cropping the
borders.
9.2.4.3 Resolution tab
Selecting a Nero Digital Profile for converting the DVD video title to MPEG-4 format defines
the size of the frame to be generated as standard.
The following input options area available:
Automatic radio button
Automatically adjusts the frame size to the Nero Digital
Profile so that the frame size generated matches the output
medium.
Custom resize
radio button
Activates the two input fields for the page format (width and
height). The values to be entered must be multiples of 16 and
must be in the range 16 to 720 pixels for width and 16 to 576
