available to tell you about transcoding video, you need to understand some important terms in this case.Especially - mention codecs.Probably everyone at least once heard this definition, but not many will be able to explain its essence.What is a codec?If you do not go into the highly specialized terminology, we can say that the essence of the work of such programs is to encode and decode information.This may be as a video and audio files.In fact, each of these codec - a special algorithm is used for encryption.Each format has its own algorithm.
codecs and players
In order to view the video, we also need the appropriate codecs.In an effort to facilitate the task of users, the majority of developers releasing players where they are built.An example is the Media Player Classic, is able to recognize and play virtually any format.In rare cases, most often after a full (or incorrectly executed) reinstall the operating system, when playing a particular file, you may receive an error.In its contents, usually referred to the lack of the necessary codecs in the system.To solve this problem can be by downloading them separately.According to the search query in the Internet you can find not only individual programs of this kind, but also the whole package, containing a set of the most popular codecs.
How transcode video and why do it?
There are times when a user needs a particular video file format.At that may have different causes.One of them - the need to reduce the size by recoding.This is due to the fact that older codecs are imperfect encryption algorithm.And videos taken with their use, takes much more space than it could.And you can inadvertently download a file from the web uncomfortable to view extension.Not so long ago, many did not know how to play video VLC, which is able to understand not every media player.Although now this problem is outdated, it explains the desire of people to learn how to re-encode the video.
Easy conversion using AutoGK
Obsolete coding at the moment can be considered as MPEG-2.Turn a video light and modern format XviD help tool called AutoGordianKnot (AutoGK).The program takes a little more than 11MB hard disk space, free of charge and fairly easy to use.The interface is in English, but practically intuitive, so that is enough for a basic knowledge of the language.During installation it is recommended to leave all the default settings except for one: When a window appears with a selection of chipsets, choose ESS.
now remains the main thing - to learn how to re-encode the video using this tool.We assume that it is already installed on the computer.So, first, we run our video transcoder AutoGK.Note that here immediately, you can choose a directory (the top two graphs) the origin of the source file and where it is stored after converting the final version.Fill these lines manually or click on the button next to each folder and set the ready.Just below the left need to select the preferred size for the destination file.If it is a movie, it will need at least 1.4 GB.On the right side there are additional options that can be used to improve image quality.
detailed example
now learn step by step how to transcode video on the example of the disc with a DVD film.Select the top row to indicate the origin of the source file.In the case of such a format, it is necessary to look for it in the folder VIDEO_TS.Typically, it contains several files with .IFO.Some may contain advertising, other menus, but you need to choose the one that takes up the most space.Probably, this is the film itself.If several movies, when you open a file it will be shown in a list.In this case, will have to convert each separately.After the opening of the video we will show its features: audio tracks and their number, the presence or absence of subtitles, duration, aspect ratio.
In case several audio tracks, ticked off just opposite interests.This will improve the quality of future film.Now write a name for the destination file and select the directory of its location (the second graph from the top).You will be able to specify the desired size.For example, to make a film in two parts, to make it easier in the future to burn it to a CD.In the advanced settings, select codec XviD.The rest can be left by default, but for better quality sound better expose Original or CBR.Then press the key combination Ctrl + F9, to open another submenu.The only thing that you need to check - is the presence of a tick at the bottom front of the ESS.
Apply your changes and click Add Job.Then you can do the same with other films on the disk.Then the list will be a few problems.Currently there is only one.Start its execution by using the adjacent button Start.All that now remains only to wait for the long process comes to an end.
