4K digital movie refers to a digital movie with a resolution of 3840 × 2160, so it is also called 2160P, that is, there are 4000 pixels horizontally, which is four times clearer than the current mainstream HD 1080P digital movie with the highest resolution, and the details are more realistic.    At present, most digital movies in China are 2K with a resolution of 1920 × 1080. The 4K movies in the real sense are shot by 4K cameras and projected by 4K projectors. Other 4K films are shot on 35mm film and converted to 4K digital format.    Since the resolution of film films in the past is roughly equal to or slightly better than 4K, the clarity of films can also be guaranteed after transcription, which is why the 4K standard has emerged in recent years, but many old films also have 4K format.    The definition is four times that of 1080P, and the video file is also four times that of 1080P in theory. The file size is mostly more than 30G. Generally, the real experience of 4K effect is to download it online first and then plug it into a TV or player through a mobile hard disk. The question comes again. Maybe some students want to ask that many set-top boxes or computers now play 4K online. Is it not troublesome to download like this? There is a big mistake. Those are fake 4K, and the effect is not as good as the 1080P downloaded. They are all realized by the base code rate and the terminal changing one pixel into four pixels. You can imagine that a real 4K compressed film has about 60G, and the length of the film is also 100 minutes, so the computing bandwidth is far from enough.

   Blu ray film refers to the film's storage medium is Blu ray disc, which has nothing to do with the film's definition and picture quality, but many high-definition film files are mostly tens of gigabytes or even hundreds of gigabytes, and the two Blu ray discs can store more than 100 gigabytes of data, which is just suitable for storing high-definition movies. Over time, it is customary to call Blu ray films high-definition movies.    4K movie refers to the resolution of the movie is 4K. The two concepts are not the same level and cannot be compared. Blu ray can also store 4K movies. 1. Blu ray, also known as Blu ray Disc, which is translated into English as Blu ray Disc, is often referred to as BD. It is the next generation of high-quality video and audio storage disc media after DVD (capable of supporting Full HD video and high-quality audio specifications). Blue ray or blue disc uses blue laser with shorter wavelength to read and write data, hence its name. Blu ray has greatly improved the storage capacity of optical disks. For optical storage products, Blu ray provides a leap forward development opportunity. 2. 4K digital movie refers to a digital movie with a resolution of 4096 × 2160, so it is also called 2160P, that is, there are 4000 pixels horizontally, which is the highest resolution digital movie on the market at present.

    The main download method of the Dwon4K download station is BT seed or magnetic link. P2P BT download tools are required. Please download BitTorrent download tools on the Internet.

1: TV or HD hard disk player At present, high-definition Ultra HD (4K) TV is very popular, but when using TV USB to play downloaded 4K high-definition movies, because most of the original 4K high-definition movies do not have their own subtitles, and most of them are foreign blockbusters, in this case we need to attach movie subtitles. The subtitle formats mainly include SRT and SSA, just change the file name of the subtitle file to the same as the movie video file name (note: the suffix name should not be changed), and put it in the same directory as the mobile hard disk. In addition, we can use Mkvtoolnix to encapsulate the subtitle file into the MKV video file. Some brands of TV need to manually select subtitle files, such as Sony 9000H series Sony 9000H loads subtitle files 2: Computer When playing high-definition movies on the computer, how to load the subtitles depends on the playback software. At present, most of them just need to change the subtitle file name to the same as the movie name (note: the suffix name should not be changed). It is OK to put it in the same directory. Some players can manually specify the subtitle file.

      It is the abbreviation of Digital Theatre System, that is, digital cinema system. It is a digital surround sound system developed from the theater mode, which was launched at the end of 1996. DTS system not only has the similar function of AC-3, but also strengthens its depth positioning cross effect. DTS chip capacity is 1536kbps, compression transmission ratio is 4:1; The AC-3 chip has a capacity of 448kbps and a compression ratio of 10:1. Due to the increase of DTS information capacity, the timbre is more beautiful. You can not only listen to Hi Fi music, but also enjoy the blockbuster movie software.    Since DTS operates at a frequency of 20 bits at 48 kHz and provides 6-channel information, the range surround sound effect it creates can meet the most critical requirements of many AV enthusiasts. Audiences are completely surrounded by this momentum, and truly experience the 360 degree digital surround sound effect.    DTS is obviously different from Dolby Digital in terms of sound quality. The former has strong sound force, sharp sound rising and cutting, clear and audible sound field, especially the rich bass effect. The latter lacks rich strength in bass, so the rise and cut of the voice seems ambiguous. In other words, DTS is slightly better than AC-3 in some details and resolution. Another feature of DTS is that it can replay the HDCD pursued by enthusiasts, which means that the sound performance of DTS can significantly surpass any of the best CD recordings at present. At present, there are many CDs in DTS format on the market.    Technically, DTS is completely different from other sound processing systems, including Dolby Digital. Dolby Digital stores the sound effect data between the holes of the film. Because of space constraints, it must adopt a large number of compression modes, so it has to sacrifice part of the sound quality. DTS solved this problem with a simple method, that is, to store the sound effect data in another CD-ROM to synchronize it with the image data. This not only increases the space, but also increases the data flow. You can also replace the CD that stores the sound effect data to play different language versions.
