What is Codec?

Codec is a program that compresses a digital stream (encoding) and also with the help of which it is reproduced (decoding). The name Codec is derived from the first syllables of these functions.

Codecs come in audio and video formats and are an important part of the media file format. the main task and the essence of the codec is to reduce the file size. At the same time, there are different algorithms for performing this task that cope with it with varying efficiency. Do not confuse the concepts of codec and file format. A format is a specific structure for representing digitized sound or image. A codec is a software algorithm that compresses a data stream in accordance with a specific format. That is, the purpose of the codec is to compress, and this can be done in different ways, therefore different codecs (with different degrees of quality) can be used for the same format. Naturally, there is no loss in quality here. However, the algorithms are so good at the task that the losses are often not noticeable. Example simple algorithm compression of audio data can serve, for example, cutting out a frequency range that is not audible to the human ear, or for example, if 2 sounds are heard, the first is loud, the second is quiet, and it turns out that the ear does not hear the second sound, it is logical that you can do without the second sound. In an image, if there is an advantage of one color in the frame, then it is enough to just describe one point with this color and indicate the places where it is repeated. Of course simple examples, in reality everything is much more complicated. Now there are lossless compression codecs. The most famous video codecs are DIVIx, Xvid, audio LAme, HD video - AVC (h264).

There are special packages for installing all the necessary codecs into the system. The most popular ones can be downloaded below:

Both codec packages do their job perfectly. So choose and install any of them.

Problems playing audio video on a computer.

The most common reason for failure to play a particular file is the lack of the required codec in the system. It happens that files with the same extension, but one starts and the other does not, or there may be no sound. The fact is that the encoding of information in them is carried out by different codecs. To obtain a specific format, a specific codec is used. That is, if there are three records in Mp3, each of which is encoded with different codecs. And the system has only one of them, then accordingly only one of these three MP3s will be played. Therefore, it is necessary to have all kinds of codecs installed in the system, then players will not have questions about how to reproduce it. One of the most popular codec libraries is the K Lite Codec Pack. This set must be present for every user and installed immediately on a freshly installed operating system.

Can't play M2TS MKV MP4 MOV MPEG2 FLV...what is a splitter?

The listed formats belong to the category of media containers. Their essence is that they are capable of containing audio and video within themselves. various formats. In addition to information about which codec the audio or video was compressed with, the player also needs to know how to open the container. For this purpose, splitters, so-called separators, are also installed in the system, thanks to which the container opens. Each type of container has its own splitter. Some players already contain built-in splitters.

HD codecs. What you need to watch high definition video.

On this moment HD video encoding is carried out using several codecs.

AVC/H264/Mpeg 4 Part 10 These are all different names for the same codec, which is currently the most popular HD codec. The reason for this is the good compression ratio when saving High Quality. However, playing video created by this codec somewhat loads the processor.

Mpeg-2 this codec was used in the first Blu-Ray discs. In terms of compression ratio, it is noticeably inferior to AVC, but at the same time it is loyal to computer resources.

VC-1 from the abbreviated Video Codec (also known as WMV3, SMPte 421M), created by such a software “monster” as Microsoft.

H.265 is a new codec designed for UltraHD 4K and 8K (with a resolution of 8192x4320 pixels).

There is also a version of Divix that supports HD.

All the necessary HD codecs and Spliters are available in any of the packages listed above.

K-Lite Codec Pack is a time-tested package of video codecs for Windows; it has been providing comfortable viewing of movies on your computer for more than 10 years.

The program consists of filters and decoders that process media files of different formats. It ensures playback of video and audio recordings without any freezes or errors.

If a movie file does not play on your computer, do not rush to blame the video player. The fact is that initially, along with Windows Media Player in operating system The simplest tools for processing multimedia files are installed. Because of this, there may be errors when playing videos and lack of support for some fairly common formats. To solve this problem, you need to download codecs. One of best options is a K-Lite Codec Pack for Windows, designed to make media players stable and fully functional.

The developers of this codec pack offer to download video codecs in four versions:

1. Basic— basic set, the only one that does not include the MPC-HC player
2. Standard- extended package includes several rarely used decoders
3. Full— there are also additional DirectShow filters, such as ffdshow and VP7
4. Mega- most full version, which also includes ACM and VFW codecs.

For the average user, the Standard version will be sufficient. If you are interested in additional DirectShow filters, which involve more fine tuning images and subtitle management, then pay attention to the Full and Mega packages.

During installation, the program prompts you to select the formats and decoders you want to work with, as well as remove “broken” components from other packages. Although, it must be said that by default everything is set to the optimal option, so there is no great need to understand the interface. However, at any time you can call the menu through “Start-Programs-Configuration”.

Possibilities:

• set of the most latest versions decoders;
• no conflicts with similar software;
• playback of all used formats (including such “hard-to-open” ones as MKV, FLAC, RMVB, HDMOV, TS, M2TS, OGM);
• built-in Home Cinema media player;
• detection and replacement of damaged or missing decoders;
• built-in utility for removing a package (or part of it);
• auto update.

Advantages:

• simple installation in a minute;
• opening all popular video files;
• Download K-Lite Codec Pack is offered free of charge.

Things to work on:

• there is no Russian-language interface, you can select Russian only in the menu;
• after removal there is a lot left unnecessary entries in the registry.

It is also important to note that the program gets along well with any media players and works even if you already have similar sets from other developers.

However, if you used one of the four packages presented, and then decided to install another, it is advisable to remove the previous one. For example, you had Standard, but you wanted to install Full. In this case, the authors recommend “demolishing” Standard. And in order to clean the registry, use a good one, for example, CCleaner.

Unlike a number of analogues, this codec set eliminates conflicts with components of other packages. And thanks to frequent auto-updates, you will only have current versions codecs.

In Windows 7 this is quite possible - the main thing is to choose the right set of audio and video codecs.

Windows 7 - what codecs are needed to play video

Few of us have ever encountered a message from our favorite video viewing program like “Unexpected File Format” when trying to launch a multimedia file. The appearance of this message means that the system does not contain the required codec to play media content. And since almost every day Computer techologies offer new recording formats that allow you to get images very good quality, it’s good to have on hand a regularly updated package with a current set of video codecs for Windows 7. At the same time, each codec has its own characteristics. For example, a file recorded in popular MKV format may well contain video materials compressed with a variety of codecs: MPEG, H264, AVC1, WMV, etc.

Windows 7 and audio codec support

While listening to our favorite music, we don’t even suspect that audio codecs compress sound file so that when it is transmitted over a communication channel or stored on a hard drive in Windows 7, it takes up as little space as possible. I exist different models audio compression, but they all implement the idea of ​​removing redundancy from an audio file - information that can be eliminated without noticeable loss of sound quality and speech intelligibility. Without going into details of compression algorithms, we can divide codecs into those that compress the signal without loss of quality (FLAC, WavPack, TTA) and those that work with deterioration of the resulting sound (MP3, OGG, WMA and some others).

We offer 2 different codec assemblies

It immediately becomes clear to any user that it is not entirely convenient to download individual codecs every time problems arise. For the convenience of our users, we provide the opportunity to download codecs for Windows 7 in the two most popular editions.
