It is regrettable to admit that progressIn addition to the obvious advantages, computer technology and multimedia technology have a number of negative qualities. For example, since several years ago, at an affordable price, providers provided Internet access at speeds from 1 to 5 megabits, users who wanted to download a feature film from the global network were forced to very well understand the question “What is quality?”. After all, hardly anyone felt the joy of re-searching and many hours of downloading a better rip. Now, with the advent of 100 megabit tariff plans, this feature has partially began to lose its relevance, although it is still necessary to know what BDRip and other symbols are. Reviews of cinema connoisseurs show that the higher the quality of the video stream, the more pleasant it is to watch. If the file is searched for a home video library, then its quality should be perfect. The definitions of “HDRip quality, BDRip, DVDRip” and others make it possible to indirectly identify some important parameters of a video recorded in a file.
Overwhelming majority of multimedia streamsData (video, sound) is now being subjected to special software processing - compression (compression). For example, the well-known “mp3” format is a bright representative of sound compression. With video, everything is more complicated, since there are many compression formats and each of them has certain advantages. This explains that the standard de facto in this area has not yet appeared.
Currently all licensed moviesdistributed on CDs. First it was a CD, then a DVD and finally Blu-Ray. Obviously, before placing a movie from a disk on the Internet, it must be converted into a convenient format: reduce the size, and turn a complex structure into a single file. For this are the programs-grabbers. The video file received at the output is called “rip” (from the English. Ripping - tearing).
It is easy to understand what BDRip is - it is a rip diskBlu-ray Since the volume of such carriers is the largest among CDs, the sound is usually high-quality multi-channel. Those who are interested in what is BDRip should know that there are several varieties of such rips, which are significantly different in picture quality. For example, “BDRip 720p” indicates that the image consists of 720 dot-lines in height. But the name "BDRip 1080p" indirectly indicates the best quality, implemented by the standard at the present time - 1920 × 1080 (Full HD).
The answer to the question “What is BDRip?»Is not limited to the displayed number of points-lines horizontally and vertically. Also used is the type of line scan. There are two types of it: interlaced and progressive. They, respectively, are denoted by the letters "i" and "p". It is believed that progressive allows you to get a more detailed image. When using it, the lines of each frame are displayed sequentially. Interlaced, as the name implies, forms a frame of two half-frames: first, even lines, and then odd lines. Due to the inertia of human vision, an illusion of a holistic image is created. The load on the decoder for interlaced scanning is less, which must be taken into account by owners of low-power video cards and weak processors. Let us give an example: the designation "BDRip 1080i" indicates a picture with a resolution of 1920x1080 and interlaced scanning. By the way, 1080i gives a higher quality than 720p.
Sometimes BDRip files up to3 GB. In this case, we are talking about a very high-quality DVDrip, since, although the original disc was Blu-Ray, in order to reduce the occupied volume, the number of pixels in the picture was reduced. For example, the same 720 points can be used in width as in the standard DVD format. Often rival rips with Blu-ray discs is HDTV (High Definition Television), though with some reservations.
