Info
Maximum bit rate
Displays the maximum bit rate of the output.
Info / Input field
Quality factor
Displays the calculated quality factor.
The quality factor is a unique quality encoding indicator used in Nero
Recode. The quality factor is defined by the number of bits per pixel
per frame to be encoded (Bits/(Pixel*Frame)). A predefined range of
values is used for the calculation of the output video bit rate. The
quality factor is an indicative value and may differ depending on the
source.
Quality slider
Defines and displays the output quality in terms of video bit rate. A
default video bit rate is preselected by a calculation based on the
quality factor. The default bit rate provides you good quality.
In order to adjust the quality individually, you can move the slider.
The color indication is based on the quality factor and gives you an
indication what to expect of the output quality:
Low: Low bit rate and low quality of the video, probably encoding
artifacts visible.
Good: A range of moderate to very good bit rates, the quality differs
if a value is chosen near the low or immoderate area.
Too high: Very good quality but too much output data which is not
needed, file size will exceed any relation to the quality.
Note: The higher the required aspect ratio, the higher the needed bit
rate. Therefore, parts of the quality slider may be grayed out, if the
required aspect ratio would result in a bit rate which is not supported
by the selected encoder or technically impossible.
Only available when the quality is set to Custom.
The following options are available in the audio and subtitle area:
Check boxes
Audio
Lists all audio tracks available for the selected video item. If you
have selected a group of items, the audio tracks are the summary of
all audio tracks in this group.
The check box in front of an audio track allows you to deselect that
track for the selected video item. This frees up space to improve the
quality of the video.
Only available if there are audio tracks available.
Check boxes
Subtitle
Lists all subtitles available on the selected video item. If you have
selected a group of items, e.g. Extras, the subtitels are the summary
of all subtitels in this group.
