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. 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. 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 an MPEG-4 SP/ASP profile in the Nero DigitalTM profile. 6. 4. 2 Quality/Speed The Quality/Speed entry allows you to make settings in relation to the quality and speed of the coding process. The Performance/Quality drop-down menu can be used to select defaults for the best possible configuration of the options. This setting option is only available if you have selected an MPEG-4 SP/ASP profile in the Nero DigitalTM profile. 6. 4. 2. 1 Motion search In the Motion search drop-down menu you can choose between None, EPZS (Enhanced Predictive Zonal Search), and EPZS². EPZS² produces the best results in this setting, but requires more time for encoding. 6. 4. 2. 2 NC Prediction You can use the NC Prediction drop-down menu 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 extrapolate the current macroblock from neighboring, non-coded macroblocks. The None setting delays the coding process because the non-coded blocks are not Page 18 Nero DigitalTM expert settings predicted but are rather analyzed in detail. 6. 4. 2. 3 Scene cut If you check the Scene cut box, you can use the slider to set the sensitivity with which the encoder detects scene changes. For efficiency, it inserts keyframes at these points whose information is used by the P- and B-VOPs. [. . . ] 6. 4. 6. 1 Intra The matrix in the Intra entry is responsible for the quantization of I-macroblocks because these are intra-coded. 6. 4. 6. 2 Inter The matrix in the Inter entry is responsible for the quantization of P- and B-macroblocks because these are inter-coded. 6. 4. 7 AVC Encoder You can make settings for the AVC encoding of your data in the AVC (Advanced Video Encoding) entry and its subentries. Page 22 Nero DigitalTM expert settings 6. 4. 7. 1 Thread count Nero DigitalTM supports multi-core processors. 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.
