With the popularity of 4K TV , many movie lovers are accustomed to collecting some 4K high-definition movies, especially some very classic high-scoring movies, which make people intoxicated every time they watch. There are many related resources on the Internet, but many people are in trouble when choosing. There are as many as a dozen versions of a 4K movie, and the capacity is very different. How should I choose?
so many 4K video formats. Which one should I choose?
First of all, it is important to note that as everyone's living standards get higher and higher, purchasing Blu-ray machine and 4K Blu-ray disc is the easiest way to maintain the original flavor of the video, and it is also a support for the producers of the video. This article only discusses different versions of multiple videos, please support genuine videos.
What we often call Blu-ray movie and 4K movies are two concepts in different dimensions. Blu-ray (Blu-Ray) refers to the way the film is suppressed, while 4K is the resolution of the film. Although the two are often used to refer to high-definition movie in spoken language, the two are completely different from conceptually. This article mainly analyzes several common types of 4K videos with a resolution of 2160p.
It is not difficult to see from the above picture that the two videos, 4K original disk and 4K REMUX, have the largest capacity, and their capacity is almost 1.5 times that of other types of videos. These two types are also the main choices for most high-definition enthusiasts at present. At the same time, we can find that there is also a considerable capacity gap between them.
Take the movie "Creedy" as an example. The capacity of the 4KREMUX and 4K original disks is nearly 6 G different. So what is the difference between these 6G?
Blu-ray original disk : Keep all the contents in the Blu-ray disc
Let’s first talk about the version of the Blu-ray original disk with larger capacity. First of all, we need to clarify a misunderstanding among many people. Blu-ray is not a playback format, but a CD storage technology for the video. Since it uses a blue laser with a short wavelength to read and write data, it is named Blu-Ray.
The Blu-ray disc that we often see is the copy source of the Blu-ray original disc movie. The original version of the Blu-ray video retains all the contents in the Blu-ray disc, including the complete menu structure, chapters, audio tracks, easter eggs, highlights, etc. are included in it. Simply put, the contents of the two are exactly the same, except that one is stored on the CD and the other is stored on the hard disk for convenient network transmission. This is also why most enthusiastic players choose the original version of Blu-ray disk, which can taste the original video, including behind-the-scenes and other interesting content.
Blu-ray disc video information
However, for many novice players, the first question after downloading the Blu-ray original disc video is: Where is the main film? is really no joke. The structure of Blu-ray is different from our common high-definition movies. It contains many instructional files and dozens of audio tracks, menu files, and even pictures and interactive software. The file format is not our common mkv, rmvb, etc., so it is a bit difficult to find the original movie.
The behind-the-scenes file contained in the Blu-ray original disk
Our common Blu-ray original disk videos are actually the index.bdmv file under the BDMV/path. Playing this file using a player that supports playing the Blu-ray original disk is the most formal and most capable of maintaining the original flavor.
. If we just want to watch movies on a computer or 4K TV, we have to look for them in the many .m2ts files under BDMV/STREAM/. This is directly transcribed from Blu-ray, but the corresponding player or TV also needs to support decoding m2ts files; the subtitle file is also built-in and cannot be plugged in. For novice players, this step is enough to dissuade them.
REMUX: "Big slimming" for Blu-ray original disk
In order to take care of the public taste, high-definition enthusiasts "slimming weight" on Blu-ray original disk videos, and the REMUX version we will talk about next appeared.
First of all, I want to emphasize that compared with the original Blu-ray disk version, the REMUX version is no different in terms of picture quality and sound quality, and we can also enjoy original 4K videos.But the whole process becomes quite simple. The REMUX version only has a single file with TS suffix, just open and play.
So what is the content less than the original version of the REMUX version compared to the Blu-ray disk version? In order to reduce capacity, the REMUX version often extracts the video and audio from the original disk losslessly and repackages it, and deletes the menus, highlights, redundant audio tracks, etc. in the original disk. , such as REMUX videos in mainland China, generally only retain two audio tracks in English and Chinese, which is enough to meet the needs of many people.
For ordinary enthusiasts, the advantages of the REMUX version are obvious compared to the original Blu-ray disk. The smaller capacity also requires less hard disk space, and it is also simpler to play, which is no different from ordinary high-definition movies; in addition, the REMUX version also supports plug-in subtitles, which is more friendly to novice players.
See this, I believe everyone has a certain understanding of the two versions, and the conclusion is also very simple. If you are a high-definition movie collector and have corresponding playback devices to restore the real Blu-ray video playback effect, and are interested in behind-the-scenes behind-the-scenes, easter eggs, etc., then the Blu-ray original disk is the most suitable version;
If you are like me, just want to watch movies on your own 4K TV, and only have certain requirements for the clarity of the movie, then the lighter REMUX version is the most suitable and the most suitable version for ordinary high-definition enthusiasts.
