Rmvb high definition edition production tutorial

(This article is reproduced from www.spdiy.com video DIY Home.) Our video compression solutions used the UFIDA ultra compression method to compress AVI files encoded by TSCC into Microsoft Video 1. However, due to the increasing use of bubble video effects, the image is becoming more and more gorgeous. Using the previous compression method, the video size will be compressed to hundreds of MB in many minutes. In order to let everyone enjoy the wonderful videos without wasting server space resources, we have developed a set of high-definition compression solutions suitable for bubble videos after long-term research and thousands of compression tests. Next I will explain this compression solution and detailed compression methods to everyone. I hope everyone will compress the high-definition rmvb video.

(This article is reproduced from www.spdiy.com video DIY Home) What is rmvb?
(This article is reproduced from www.spdiy.com video DIY Home)
(This article is reproduced from www.spdiy.com video DIY Home.) Rm everyone must be familiar with it, short for RealMedia. It is a coding solution developed by RealNetworks for transmitting video information on the network, other similar encoding schemes include ASF, WMV, and mpg. The VB behind rmvb is actually a VBR, which means "Dynamic Bit Rate ". The biggest difference between rmvb and RM is that Rm is a fixed bit rate (bit rate: the number of bytes contained in the video file per second), while rmvb is a dynamic bit rate. The difference between the fixed bit rate and the dynamic bit rate will be discussed later. In short, rmvb is much better than RM.

(This article is reproduced from www.spdiy.com video DIY Home) Delete: Click Delete after a file is selected. This file will be removed from the compressed list.
(This article is reproduced from www.spdiy.com video DIY Home) clear: Clear the compressed file list
(This article is reproduced from www.spdiy.com video DIY Home) start to compress: Start to compress the files in the list. After compression, we can see the progress bar, the compression prompt information, the current time position of the source, and clockwise rotation.
(This article is reproduced from www.spdiy.com video DIY Home)
(This article is reproduced from www.spdiy.com video DIY Home.) after you start to compress, you will find that starting to compress turns into stopping compression.
(This article is reproduced from www.spdiy.com video DIY Home). If you do not want to compress, click here to stop. Before starting compression, you can select "shut down after completion". If you select this option, the software will automatically shut down after compression is completed. This is very suitable for hanging up all night flags. After the software is compressed, a prompt box will pop up asking you to choose whether to shut down. There is a 30-second wait time. If you do not want to shut down, click "no ".
(This article is reproduced from www.spdiy.com video DIY Home.) If you do not select "shut down after completion", you will see this prompt after the press is complete.

(This article is reproduced from www.spdiy.com video DIY Home) rmvb video solutions can be divided into two categories. The first type is fixed bit rate compression. The compressed files are RM encoded and the file suffix is. rm. The other is Dynamic Bit Rate compression. It is rmvb encoding, And the suffix of the generated file is. rmvb.
(This article is reproduced from www.spdiy.com video DIY Home)
(This article is reproduced from www.spdiy.com video DIY Home) Dynamic Bit Rate compression can be divided into two sub-classes. The maximum bit rate + average bit rate, and the maximum bit rate + video quality.
(This article is reproduced from www.spdiy.com video DIY Home)
(This article is reproduced from www.spdiy.com video DIY Home.) Now let's talk about the connection and difference between them.
(This article is reproduced from www.spdiy.com video DIY Home)
(This article is reproduced from www.spdiy.com video DIY Home) fixed bit rate: the amount of data contained in video files per second remains unchanged, for example, the files compressed by 500 kbps/s, the image of the original file above 500 kbps will be forcibly reduced to 500 kbps, and the low and 500 will also be filled to (a waste ). The disadvantage of fixed bit rate lies in the unstable quality of the encoding content. Because some parts of the content are more difficult to compress than other parts, the quality of some parts of the image is worse than that of other parts. In addition, the fixed bit rate may lead to different quality of adjacent streams. Generally, at a low bit rate, the quality changes more significantly.
(This article is reproduced from www.spdiy.com video DIY Home)
(This article is reproduced from www.spdiy.com video DIY Home) Dynamic Bit Rate: When dynamic bit rate is used, the system automatically allocates a small number of BITs to the simple part of the content, in this way, a sufficient number of BITs are used to generate high-quality complex parts. When dynamic bit rates are used for mixed content, the output results of dynamic bit rates are much better than those of fixed bit rates under the same file size and size conditions. In some cases, a dynamic bit rate file with the same quality as a fixed bit rate file may have only half the size of the former.
(This article is reproduced from www.spdiy.com video DIY Home)
(This article is reproduced from www.spdiy.com video DIY Home) maximum bit rate + average bit rate: reduces the image bit rate higher than "maximum bit rate" in the original file to "maximum bit rate ", the image below the "average bit rate" is increased to "average bit rate ". For example, if the maximum bitrate is set to 1000 and the average bitrate is 500, the image with a bitrate greater than 1000 in the original file will be forcibly reduced to 1000, while the bitrate lower than 500 will be forcibly increased to 500. In the middle. It is a bit similar to a fixed bit rate, but it does not waste as much space as a fixed bit rate.
(This article is reproduced from www.spdiy.com video DIY Home)
(This article is reproduced from www.spdiy.com video DIY Home) The largest bit rate + picture quality: the amount of data on all images in the original file is left with a quality coefficient. For example, if the mass coefficient is set to 80%, It is multiplied by 0.8. However, if the bitrate is higher than the "maximum code rate" after multiplication, it will be forcibly reduced to "maximum bit rate. The disadvantage of the average bit rate is that if the quality coefficient is too high, the file is almost too much pressure and the setting is too low, the image with a low data size in the original file will become very low after passing the quality coefficient, making the video file look blurred.
(This article is reproduced from www.spdiy.com video DIY Home)
(This article is reproduced from www.spdiy.com video DIY Home) from the above analysis, we can see that the maximum bit rate + average bit rate scheme using dynamic bit rate is the best, this is why the mainstream rmvb compression solutions on the network now use the maximum bit rate + average bit rate. This compression scheme is also used here.
(This article is reproduced from www.spdiy.com video DIY Home)
(This article is reproduced from www.spdiy.com video DIY Home) we set the highest bit rate to 9999 or even greater.
(This article is reproduced from www.spdiy.com video DIY Home)
(This article is reproduced from www.spdiy.com video DIY Home). Why? Because we want to press the high-definition version. Generally, pictures with higher bit rates have relatively large changes, such as 3D conversion. If we do not want the image quality to be too high, it is best to set the maximum bit rate of the original AVI file, but since the maximum bit rate exceeds the maximum bit rate of the original AVI file, there will be no major changes (the bit rate and file will almost remain unchanged ), so it does not matter if we set it to 9999 or 99999.
(This article is reproduced from www.spdiy.com video DIY Home)
(This article is reproduced from www.spdiy.com video DIY Home) average bit rate is generally set to half of the AVI file bit rate!
(This article is reproduced from www.spdiy.com video DIY Home)
(This article is reproduced from www.spdiy.com video DIY Home.) What is the AVI file bit rate? See
(This article is reproduced from www.spdiy.com video DIY Home)
(This article is reproduced from www.spdiy.com video DIY Home)
(This article is reproduced from www.spdiy.com video DIY Home) The first avi file must be first compressed into Microsoft Video 1 by youli or other software, otherwise the value may vary greatly. Right-click the AVI file to be compressed, select properties, and select "summary" in the pop-up Properties dialog box. The displayed information is displayed. The "data rate" is the AVI file bit rate. The AVI file bit rate is 932kbps.
(This article is reproduced from www.spdiy.com video DIY Home)
(This article is reproduced from www.spdiy.com video DIY Home) So in the above configuration scheme, I set the average bit rate to 450 (actually it should be 466, but there is no big difference in getting an integer of 450)
(This article is reproduced from www.spdiy.com video DIY Home)
(This article is reproduced from www.spdiy.com video DIY Home) What if the AVI file bit rate is very low? For example, if a video image AVI file has a bit rate of 300, the average bit rate is 150 according to the stress described above, and the pressure is blurred. What if there is a high Avi bit rate? For example, more than 2000.
(This article is reproduced from www.spdiy.com video DIY Home)
(This article is reproduced from www.spdiy.com video DIY Home) So here we stipulate that the average bit rate is not less than 200, and the maximum bit rate is not higher than 1000, so no matter what files are pressed, it will be clear, it will not waste a lot of file space
(This article is reproduced from www.spdiy.com video DIY Home) video mode: select based on your video source.
(This article is reproduced from www.spdiy.com video DIY Home) normal motion video normal action video; this option can be selected for general movies
(This article is reproduced from www.spdiy.com video DIY Home) smoothest motion is a smooth action video, such as cartoons, you can choose this
(This article is reproduced from www.spdiy.com video DIY Home) sharpest image is a very sharp action video. For example, you can choose this option for many large movies.
(This article is reproduced from www.spdiy.com video DIY Home) slide show; do you have a slide-like film? If you have one, you can use this option.
(This article is reproduced from www.spdiy.com video DIY Home) No video. If you decide to select the audio from the video source
(This article is reproduced from www.spdiy.com video DIY Home) Video Encoding: If Dynamic Bit Rate is adopted, realvideo9 is recommended. If a fixed bit rate is used, realvideo8 can be used. Here we use dynamic bit rate, so we use realvideo9.
(This article is reproduced from www.spdiy.com video DIY Home)
(This article is reproduced from www.spdiy.com video DIY Home) Audio mode: music is much better than voice. You can also select no audio to compress a dumb movie.
(This article is reproduced from www.spdiy.com video DIY Home)
(This article is reproduced from www.spdiy.com video DIY Home) Audio Encoding: we are watching videos, not listening to songs, so there is no need to pursue such a high audio quality, our study found that the 64 Kbps stereo music audio encoding is the most suitable.
(This article is reproduced from www.spdiy.com video DIY Home)
(This article is reproduced from www.spdiy.com video DIY Home) filter settings: compression of high-definition version rmvb video generally does not adjust the screen size, bubble video resolution is generally, here we do not adjust. Rmvb for online compression needs to be used here.
(This article is reproduced from www.spdiy.com video DIY Home)
(This article is reproduced from www.spdiy.com video DIY Home) Editing information: Generally, the title is the same as the file name (provided that your AVI file name is the title of your video). The producer can enter your own name.
(This article is reproduced from www.spdiy.com video DIY Home)
(This article is reproduced from www.spdiy.com video DIY Home) Output path: Select "Same as input file path". In this way, the compressed file will be in the same directory as the original file.
(This article is reproduced from www.spdiy.com video DIY Home)
(This article is reproduced from www.spdiy.com video DIY Home) after all the settings are complete, you can click "Save as default" and you will not need to reset it every time, you only need to change the average bit rate. If you have many compression solutions, you can also "save" as a configuration file. In the future, "read" will be used to directly read the compression scheme.
(This article is reproduced from www.spdiy.com video DIY Home.) Well, the parameter settings are also finished. Next, let's summarize:
(This article is reproduced from www.spdiy.com video DIY Home)
(This article is reproduced from www.spdiy.com video DIY Home) ①: The maximum bit rate is set to 9999.
(This article is reproduced from www.spdiy.com video DIY Home) ②: the average bit rate is half of the AVI bit rate, but the minimum is not less than 200, and the maximum is not higher than 1000. The AVI bit rate should be the bit rate of the AVI file that has been superpressed by friends. It is not TSCC encoded. (In fact, there is no need to compress rmvb for an AVI file with a Avi bit rate lower than 400. It is generally smaller and clearer to compress the file with the ultra-compression method)
(This article is reproduced from www.spdiy.com video DIY Home) ③: Select sharpest image in video mode.
(This article is reproduced from www.spdiy.com video DIY Home) ④: Select realvideo9 for video encoding.
(This article is reproduced from www.spdiy.com video DIY Home.) ⑤: Select 64 Kbps for Audio Encoding stereo music
(This article is reproduced from www.spdiy.com video DIY Home) ⑥: Set the title to the same file name and change the name of the producer.
(This article is reproduced from www.spdiy.com video DIY Home) 7: select the path of the same input file
(This article is reproduced from www.spdiy.com video DIY Home) Tips: Save all settings as the default configuration
(This article is reproduced from www.spdiy.com video DIY Home) Tips: Save your configuration, or you can download the configured configuration file and read it directly.
