About Nero Recode

Nero Recode enables you to copy non-copyright DVD videos onto DVD for archiving purposes. If the source video is larger than 4.7 GB, it is compressed to fit on a single layer DVD disk without loss of quality. You can also exclude unwanted material on the source DVD from the copying process (including subtitles or soundtracks) thereby making space for additional videos or for better video quality. As an alternative, the target DVD can also be recorded on the hard drive in the form of a DVD video directory or can be created on the hard drive as a so-called disk image. Naturally, you can also choose to produce your own compilation from the contents of various (non-copyright) DVDs and then export it to the pioneering Nero Digital MPEG-4/ H.264 AVC, for example, and then to burn it onto disk. It doesn't matter whether the video is intended for portable devices or HDTV because the different export profiles enable you adapt the output size to your requirements and you will always receive the best quality relative to the file size. So, Nero Recode lets you copy, recompile and recode the contents of DVs and DVDs and then to burn the results onto disk.

Versions with different ranges of functions
Nero Recode is not just available in the full version. The versions differ from the full version in terms of the range of functions, i.e. not all the tasks described in this manual can be resolved and the user interface is adapted to the specific version.

The following versions are available: Nero Recode Full version Nero Recode Essentials The following features of the full version are not included: PSP export function iPod export function Nero Recode Essentials SE Exclusive features: Recode complete DVD to DVD Burn function (via Nero API) Nero Recode Essentials CE The following features of the full version are not included: Recode complete DVD Recode Main Movie to DVD Change the structure of a DVD

Terminology

Encoding means the conversion of a video of any format into another format, e.g. MPEG2 or Nero Digital (MPEG-4). A corresponding encoder is required for every target format. Transcoding means converting a video from a particular format into another particular format, e.g. from Xvid to MPEG-2. Recoding involves converting an existing video with certain properties (e.g. bit rate 2500 kbit/s) into the same format with different properties (e.g. bit rate 1990 kbit/s). Decoding means opening or playing a video that has been encoded in a particular format.
In this manual transcoding is used synonymously with encoding.

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: 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 deinterlacing to increase Nero Digital image quality. The Enable option converts the video title.

De-Interlace Video area

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 Custom Crop radio button Adjust button Disable radio button 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 Custom resize radio button Automatically adjusts the frame size to the Nero Digital Profile so that the frame size generated matches the output medium. 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

pixels for height. Disable radio button Letterboxed check box Allows the video to be converted without changing the frame size. Creates a Nero Digital file consisting of square pixels. Some, players require square pixels.
9.2.5 Set Nero Digital options
The following additional setting options become available when converting to Nero Digital: Current Profile drop-down menu Displays the Nero Digital Profile you selected in the My Nero Digital Disc screen. Only one profile is available by default, however you can create another one. Creates a new profile. You can then select this in the Current Profile drop-down list. Deletes the profile selected in the Current Profile drop-down list. Specifies the method to be used to code the MPEG-4 file. Switches to Expert Settings mode (see Nero Digital expert settings)
New button Delete button Coding Method input box Expert Mode check box
You should only change the expert settings if you are sufficiently familiar with the area of video encoding Incorrect settings can have a major negative impact on the quality of the output file.

Seite 41

Recode main movie to Nero Digital
Nero Recode allows you to encode DVD video files as Nero Digital files. The Nero Digital codec is MPEG-4-compatible. This option allows you to encode just the main movie on a DVD without the Extras. You can then play this back, for example in Nero ShowTime.
10.1 Task-specific input options

11.1 MPEG-4 terminology

To clarify the options available in expert mode, a number of terms are defined in greater detail below: AVC ASP Advanced Video Coding. Complies with H264 standard. See H264. Advanced Simple Profile. Complies with H263 standard. See H263. Bidirectional coded frame. Only uses the difference information relative to previous and subsequent key frames (I frames). Because only the difference information is used, rather the full frame information, compression is greater. Bidirectional coded Video Object Plane (see B-Frame). VOP is only referred to in the context of coding in the H263 standard. Context Adaptive Binary Arithmetic Coding. The name of a process for arithmetically coding digital video data as part of coding standard MPEG-4 AVC and H.264. Process in which data is compressed so that it needs less storage space and shorter transmission times in data networks. Enhanced Predictive Zonal Search. An algorithm for finding motion in video sequences. Group Of Pictures. The interval from one I-Frame to the next. ITU standard for video decoding and compression. Video compression standard which uses a similar approach to MPEG-2, but is much more efficient. Intra coded Frame. Contains the complete integral information for a particular frame. Intra coded Video Object Plane. See I-Frame. VOP is only referred to in the context of coding in the H263 standard. Horizontal skip process. Used when recording, processing and displaying images. Mainly used for displaying television signals on receivers based on the CRT principle. International Organization for Standardization. International Telecommunication Union. See I-Frame.

Macroblock

A macroblock describes 16 x 16 pixels and is the elementary unit in the MPEG standard on which motion coding is also based. A matrix is a rectangular pattern whose elements are usually numbers, although they can be other mathematical elements such as variables of functions. It consists of m lines and n columns. In relation to qualification: the values in the matrix are factors that control the value of the compression. The higher the number the greater the compression. Motion estimation/ motion search. An MPEG standard (ISO/IEC-14496) that describes the process of video and audio compression, among other things. Video compression is divided into MPEG-4 AVC (see H264) and MPEG-4 SP/ASP (see H263). Not Coded. Predictive Frame. Uses only the difference information relative to the previous and subsequent key images (I-Frames). Because only the different information is used, not the complete image information, the degree of compression is greater. Predicted Video Object Plane. See P-Frame. VOP is only referred to in the context of coding in the H263 standard. Prediction/estimate General: The generation of a digital signal from an analog signal.

Quantization
In video compression: Quantization controls the degree of compression. It involves the reduction of the value range by a division-type operation. Interference in image or sound. Generally an interfering parameter with a broad, unspecified frequency spectrum. It can thus be interpreted as the overlayering of numerous oscillations or waves of varying amplitude and frequency or wave length. See I-Frame. A video frame. This is how a frame is referred to in the context of MPEG-4 SP/ASP.

11.2 MPEG-4 profiles

MPEG-4 SP/ASP is mainly available in two different profiles, Simple Profile (SP) and Advanced Simple Profile (ASP). Nero Recode allows you to choose the profile in which the files are to be output (see Simple Profile (QuickTime compatible)). The functions are supported by the various profiles as follows: Functionality Profile Simple I-Frame P-Frame B-Frame AC/DC Prediction 4 motion vectors per macroblock / unlimited motion vectors H.263 / MPEG quantization Global Motion Compensation Interlace process x x x x Advanced Simple x x x x x x x x
Various entries are available for selection in the Profile area in the navigation tree. The entries under the MPEG-4 encoder main point are explained below. The option for changing settings depends on the selection made in the Nero Digital Profile and Nero Digital Category drop-down list. Some selection options cannot be changed and are therefore grayed out.

11.2.1 Create a new profile
To create a new profile for the Nero Digital settings, proceed as follows:
1. Click on the New button.
The New Profile dialog window will open.
2. Enter the name for the new profile. 3. Select the profile from which the settings are to be copied from the drop-down list. 4. Click on the OK button.
You have now created a new profile. You can now continue to make more settings in expert mode.

Seite 48

11.2.2 Encoding mode
The Encoding mode setting allows you to choose between the Real-time encoding (1 pass) and High quality encoding (2 pass) settings. Coding in a single pass may take less time, but it does not offer the same quality as coding in two passes. If coding in a single pass is selected, two fields are available, Min. quant. and Max. quant. You can use these to set the range for the permitted quantization factor. This determines the degree of compression for the output file. Remember that while greater compression reduces the output, it also involves a loss of quality. For this reason you should never exceed a quantization factor of 31.
This setting option is only available if you have selected Nero Digital, Sony Memory Stick-Video or Apple iPod in the Nero Digital category.

11.2.3 Quality/Speed

The Quality/Speed entry enables you to make settings in relation to the quality and speed of the coding process. The Performance/Quality drop-down list can be used to select settings for the best possible configuration of the options. When you choose Custom you can select the options yourself. These options are explained below. This setting option is only available if you have selected Nero Digital, Sony Memory Stick-Video or Apple iPod in the Nero Digital category.

11.2.3.1

Motion search
In the Motion search drop-down list you can choose between None, EPZS (Enhanced Predictive Zonal Search) and EPZS. These are algorithms for reducing image information in P and B-VOPs. EPZS produces the best results in this setting, but requires more time for encoding. The None setting produces the lowest coding efficiency. For this reason it is not recommended.

11.2.3.2

NC Prediction
You can use the NC Prediction drop-down list to set the speed of the prediction of noncoded macroblocks. If you choose Fast, an attempt will be made to use a fast process to close the current macroblock from neighboring, non-coded macroblocks. However, the quality of the output file is poorer. The None setting delays the coding process because the non-coded blocks are not predicted but are rather analyzed in detail. This produces the best possible quality. The Normal setting is recommended as it is the middle way.

11.2.4 Advanced

You can make further settings relating to various areas of the encoding in the Advanced entry. These are explained below. These setting options are only available if you have selected Nero Digital, Sony Memory Stick-Video or Apple iPod in the Nero Digital category.

Seite 50

11.2.4.1
Simple Profile (QuickTime compatible)
If you check the Simple profile box, a number of options in expert mode are grayed out and cannot be changed. The output file is thus encoded in the MPEG-4 simple profile (see MPEG-4 profiles).

11.2.4.2

The Quantization drop-down list allows you to choose between H236 Quantization and MPEG Quantization. Select MPEG if you want to use your own quantization matrix or change the existing one. If you do not want to do this, leave the setting at H263 quantization.

11.2.4.3

Pixels
You can choose between Half and Quarter Pixel in the Pixel drop-down list. Motion is then sought in quarter or half pixel steps. If estimation is in quarter pixels, the coding process takes longer, but the quality is better

11.2.4.4

Spatial prediction
The Spatial Prediction setting is used to encode macroblocks in correlation with neighboring macroblocks. In other words, they are coded with difference information relating to these neighboring macroblock and on the basis of the probability of similarity. The information from several intracoded neighboring macroblocks is used to be able to predict a macroblock more accurately.

11.2.4.5

The P-VOP setting enables encoding using P-VOPs.

11.2.4.6

Unrestricted Motion Vectors
If you check the Unrestricted motion vectors box, you allow the motion vectors also to relate to points outside the frame. This option improves coding efficiency on the edge of the frame.

11.2.4.7

4 motions vectors per macroblock
The 4 motion vectors per macroblock setting allows the encoder to divide the macroblocks of 16x16 pixels into four 8x8 pixel macroblocks for the motion search. This means that there are now four motion vectors instead of one. This option improves the quality but slows down the encoding process.

11.2.4.8

Bidirectional VOP
The Bidirectional VOP setting permits encoding with the help of B-VOPs.

The Thread Count drop-down list allows you to choose whether to allow the encoding process to be performed by several threads. This means that you can use a multi-core processor system to optimum effect. The number of processor cores used corresponds to the number of threads you have selected.

11.2.8 Bitrate mode

The Bitrate mode entry can be used to make settings in relation to the bit rate mode and quantization (see Encoding mode).

11.2.9 General settings

The General Settings entry is used to make settings for the Decision Quality, the Motion Vectors and the GOP Properties. These setting options are only available if you have selected Nero Digital AVC in the Nero Digital category.

11.2.10

Decision quality
The Decision Quality control indicates the required quality of the output file in relation to the time expended. High Quality produces the best quality with the longest encoding period. High Speed requires the shortest encoding period with the poorest possible quality. We recommend a medium value in the Best range.

11.2.10.1

Motion vectors

See Maximum MV range.

11.2.10.2

GOP properties

A GOP (Group Of Pictures) is an interval from one I-Frame to another. Maximum reference frames The number in the Maximum Reference Frames field indicates the number of frames from which a P or B-Frame may draw its information. If B-Frames are permitted, the number must be at least 2.

Seite 53

Maximum GOP size The number in the Maximum GOP Size field indicates the number of frames permitted between I-Frames. Maximum B-Frames The number in the Maximum B-Frames field indicates the maximum number of consecutive B-Frames that can be used in a GOP.

About This Application

Nero Recode allows you to copy non-copy-protected DVD videos to DVD, which is a method of archiving your content. If the source video is larger than 4.7 GB, it is compressed to fit on a single-layer DVD without loss of quality. You can also exclude unwanted material on the source DVD from the copying process (including subtitles or soundtracks) thereby making space for additional videos or for better video quality. The target DVD can also be written to the hard drive as a DVD video index or as a so-called disc image. Of course, you can also compile content from different (non-copy protected) DVDs, export them to the innovative Nero Digital MPEG-4/H.264 AVC format and burn them to create your own collection. No matter whether the video is intended for playing on mobile devices or HDTV, the various export profiles allow you to adjust the output format to your requirements - and you always get the best quality for your respective file size thanks to the various export profiles. Thus, Nero Recode lets you copy, recompile, and recode the content of DVs and DVDs and then to burn the results to disc.

The setting relates to the target medium for which encoding is being carried out. Selects the method to be used to encode the MPEG-4 file. If you select Fast (1-pass), the movie only undergoes one conversion pass. This method requires less time but has lower quality than encoding in two steps. The movie is analyzed and converted with the available bit rate simultaneously. If you select High quality (2-pass), the movie undergoes several conversion passes. The quality is better, but the process takes longer. The first pass analyzes the movie and creates a temporary file (*log). The second pass converts the file. During this process, the bit rate data that was stored in the temporary files is used. The Video tab shows the video title's properties. The following information is available: Column Properties Shows the video properties stored on the DVD, e.g. resolution, frame rate, pixel format, video structure, and duration.

A Group of Pictures refers to a group of consecutive individual pictures in the picture flow of a video file. Each movie or video flow consists of consecutive GOP's. The viewable individual pictures are generated from them.

Interlace

The interlacing process, which is used to display a TV picture 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. When this is complete, the second half frame is generated from the even lines. The two frames are encoded separately. The relatively high refresh frequency means that the eye picks this up as a single frame.

Lanczos interpolation

Lanczos interpolation refers to an image enlargement method. The method was developed according to an algorithm created by Cornelius Lanczos. This interpolation method provides high quality and good sharpness levels. However, the actual visual resolution of the images is not increased.

Letterbox

Letterbox refers to an aspect ratio transferring method with which, e.g. a video file with 16:9 aspect ratio is adjusted for the 4:3 television aspect ratio. Black bars are placed above and below the picture.

Macroblock

A macroblock refers to a block consisting of 16x16 pixels, and constitutes the basic unit in the MPEG standard, on which motion encoding is based as well. A macroblock contains information regarding the brightness and color distribution of a video picture.

MPEG-2

The Moving Picture Experts Group defined this industry standard for video and audio codecs. There is little difference between MPEG-1 and MPEG-2: MPEG-2 is a broadcast standard and better for televisions that are interlaced. MPEG-2 is used as a video format for DVDs.

MPEG-4

The Moving Picture Experts Group defined this industry standard for video and audio codecs. MPEG-4 is the latest MPEG standard for video and audio. MPEG-4 combines several
Glossary functions from MPEG-1, MPEG-2 and other standards. Nero Digital Video and Nero Digital Audio are based on this standard.

Multithreading

Multithreading refers to a processor's capability of processing several tasks simultaneously. In the field of software, it also refers to the distribution of computing work for a certain task among several processors.

P-frame

P-frames (predicted frames) refer to predicted pictures in MPEG compression. They are based on predictions and guesses from previous intra-frames (I-frames) and P-frames. They only include the change information in comparison the the previous frame. Since P-frames feature a higher compression ratio than I-frames, the compressed data volume is smaller, since only the changes are saved in the frame.
