[. . . ] An MPEG standard (ISO/IEC-14496) that describes the procedure for video and audio compression, among other things. Video compression is divided into MPEG-4 AVC (see H264) and MPEG-4 SP/ASP (see H263). Matrix Motion Estimation MPEG-4 NC Not Coded. Uses only the difference information relative to the previous and subsequent keyframes (I-frames). Because only the difference information is used, not the complete image information, the degree of compression is greater. VOP is only referred to in the context of coding in the H263 standard. In general: The creation of a digital signal from an analog signal. P-Frame P-VOP Prediction Quantization During video compression: Quantization controls the degree of compression. It involves the reduction of the value range through a division-type operation. Generally a disturbance with a broad, unspecified frequency spectrum. It can thus be interpreted as the superimposition of numerous oscillations or waves of varying amplitude and frequency or wave length. A video picture in the MPEG-4 SP/ASP context. Interference RVLC Keyframe VOP Page 16 Nero DigitalTM expert settings 6. 2 MPEG-4 profiles MPEG-4 SP/ASP is mainly available in two different profiles, Simple Profile (SP) and Advanced Simple Profile (ASP). The functions are supported by the various profiles as follows: Function 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 (see MPEG-4 Encoder). The option for changing settings depends on the selection made in the Nero Digital Profile drop-down menu (see Nero DigitalTM profiles). Unavailable selection options are grayed out. 6. 3 Creating a new default profile for expert settings To create a new default profile for the Nero DigitalTM expert settings, proceed as follows: 1. Enter a description in the Description box. Click on the Default button. You have now created a new default profile for the Nero DigitalTM expert settings. You can now define the Nero DigitalTM expert settings for your new default profile. Page 17 Nero DigitalTM expert settings 6. 4 MPEG-4 Encoder You can make the Nero DigitalTM expert settings in the MPEG-4 Encoder entry. 6. 4. 1 Encoding Method The Encoding Method entry 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. 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. [. . . ] If you have one of these, you can distribute the encoding process over the required number of threads. The Thread Count drop-down menu 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. 6. 4. 8 Rate control The Rate control entry allows you to make settings in relation to the bit rate mode and quantization (see Encoding Method). 6. 4. 9 General Settings The General Settings entry allows you to make settings in relation to Decision quality, the Motion vectors, and the GOP properties. This setting option is only available if you have selected an MPEG-4 SP/ASP profile in the Nero DigitalTM profile. 6. 4. 10 Decision quality The Decision quality slider specifies the quality of the output file in relation to the time expended. High Quality offers the best quality with the longest encoding period. [. . . ]
