DVDRIP has been enthusiastically sought after by its high-definition picture, and the audible AC3 sound effect has been enthusiastically sought after. Since the introduction, it has been popular in the Internet, almost become the preferred format of network movies. However, although DVDRIP is much more advantage, it is a lot of shortcomings: a large number of hundredgaps, many plugins, the huge occupation of system resources, the difficulty of decoder configuration, and the cumbersome time, etc., all are somewhat Limits its development. Recently, the new generation of video format RMVB is born, but also a serious movement of DVDRIP.
What is RMVB format
The so-called RMVB format is extended in the RM movie format of the streaming. VB is VBR, which is the English abbreviation of Variable Bit Rate. When we play a common RM format movie in the past, we can see 225kbps in the lower left corner of the player, which is the bit rate. The still picture of the movie is different for the compressed sampling rate. If the fixed bit rate is always fixed, it will cause waste of the movie.
RMVB breaks the average compression sampling of the original RM format, and the maximum sample rate value of twice the average sample rate is set based on the average compression ratio. The higher bit rate is used for complex dynamic screens (songs and dances, speeds, wars, etc.), and in the static screen, flexibly convert to lower sampling rates, reasonably use bit rate resources, so that RMVB is small at sacrifices Some of the volume of the movie that you missed, the size of the movie was mostly compressed, and finally had a near-perfect audiovisual effect, as shown in Figure 1, the RMVB format "Saint Seiyou King". It can be described as a volume and sharpness "fish and bear's own", and its development prospects cannot be underestimated.
In contrast, DVDRIP is concerned, the advantage of RMVB is self-evident. First, under the premise of ensuring the overall audiovisual effect of the movie, only 300 ~ 450MB (calculated by 90 minutes), while DVDRIP requires 700MB or more; the subtitles of the RMVB are embedded, unlike DVDRIP That is to install the debug subtitles plus plug-in software, sometimes there will be garbled; more importantly, the RMVB video playback only needs to install the decoder at once, and no matter whether the image is still no need to debug. DVDRIP is video, audio decoding a lot, and improper setting will cause phenomena that can not be synchronized, and the flower screen is lost.
RMVB play environment
According to the experience of the author, the best RMVB playing tools currently is Realone Player 2.0. Since it is a new VBR encoding technology, the player must install RealVideo 9.0 or more decoders. If you use RealPlayer Basic or RealPlayer 8.0 to play RMVB movies, the software will automatically connect to the RealNetworks website and prompt you to upgrade the installation associated plugin.
Making RMVB movies
Since RMVB has overcome the shortcomings of DVDRIP, it also has the characteristics of flowing media files in playback, then it will become the mainstream of network movie propagation. Saving the movie with the RMVB format, which improves production efficiency and saves storage resources - if we need to carry the entire DVD movie into the plate with you, only one 700m disc is enough - can be said to be the advantage A lot of. Therefore, learn the film of RMVB format, which is gradually become a new fashion of multimedia enthusiasts.
Using Helix Producter Plus 9 This software we can easily produce high quality RMVB movies, but to note that during the production process, you must have a lot of effort. If interrupt, you must start again. The following author converted into RMVB as an example with a DVDRIP file, and concludes the production process: 1. Import source file runs Helix Producter Plus, pops up as shown in Figure 2, in "'Input File" Click the "Browse" button to import the DVDRIP source file. The import time will depend on the size of DVDRIP. 2. Parameter setting Click "Audiences" in the right of the window to remove the "2-pass Video Encode" in the setting interface. Then remove the four multi-rate templates in "Audiences in Job", and then select the "S-450K Surround VBR Download" template from the left "templates" to the "Audiences in job" (Figure 3).
Double-click the newly added "S-450K Surround VBR Download" template, the template setting window appears, it is recommended to change the "maximum bit rate" to 2000; set "Target Video Quality" to 100% (Figure 4), other remaining default.
Select "Settings → Show Audio Gain Control" on the main window, and make the volume size setting in the "GAIN" window. In addition, the setting of copyright information can be implemented by clicking the "CLIP Information" button. Finally, click "Encode" in the lower right of the main window to start compression. Ok, go to the cup of coffee, wait for the RMVB master you made!
Making RMVB is also good for domestic Batch Real Producter V1.5.3.1. It feels easy to use than REAL's HELIX Producer 9.
Batch Real Producer is a batch RM file generator. Using a new Realvideo9 core. Unlike the current other Real9 format compressor, BRP is to call Real9's core to compress, rather than calling the command line of Helix Product Plus 9 to implement compression. Many file formats can be supported. For example: AVI, MPG, VOB, DAT (VideoCD file), etc., as long as it is a media file that can be played by Microsoft's DirectShow interface, it is basically imported. The specific features of this software are: 1. You can set the compressed list, and the software is compressed in automatically in the list. 2. You can choose to automatically shut down after compression, which is easy to run for a long time. 3. With the watchdog function: If the source file is wrong, the compression engine is deadlock, the system automatically terminates the compression of the current file after 180 seconds (the termination process is about 20 ~ 40 seconds), and the next file in the list is started. 4. Internal empirical parameters are used, and users can compress high-quality RealMedia files without setting any parameters!
