Encoding Video Files

Nero Recode

The value is determined by the output settings you have selected

and is updated in real-time to any made change.

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.
