K lite codec pack installation. Clarifications for K-Lite Codec Pack

Is it necessary before installation? new version codec package K-Lite Codec Pack to delete the previous one?
Actually, it never hurts. But when installing K-Lite Codec Pack, the removal procedure previous version is not mandatory. If the new version contains only minor changes, you can simply install it over the old one. This will not lead to any problems and everything will work fine. If more significant changes have occurred in the package, the installer will ask you to remove the previous version.

At first K-Lite installations Codec Pack asks me if I want to remove program X. Is this necessary?
No, this is not necessary. Just click on "No" if you want to save installed program. But if you are using another codec package, then removing it will be highly recommended. This will save you from problems and help keep the system clean.

At the beginning of the installation I am asked if I want to uninstall RealPlayer. It is necessary?
No, not necessarily. Just click on "No" if you want to keep RealPlayer. But if you want to use Real Alternative, you must uninstall RealPlayer.

During installation, an error occurs: “An error occurred while trying to replace the existing file: DeleteFile failed; code 5. Access denied."
This means that the installer is trying to remove a file that is currently in use by another program. Close all active programs and click on “Retry”. If the error persists, click “Skip” and continue with the installation.

Is it possible to remove only some components of the K-Lite Codec Pack and leave the rest.
No, you must remove the entire codec package. Then run the installation from the beginning and in the right place select only those components that you need. You can also disable (and then enable back) all codecs and filters using the Codec Tweak Tool. This program does not remove codecs and other components, but only effectively blocks them.

Does K-Lite Codec Pack contain an uninstaller?
Yes.

The error “Error writing to registry key” occurs.
This error occurs when incorrect settings access for register keys. To fix the problem, open the registry editor:
Start -> Run... -> regedit.exe
In the registry editor, find the key causing the problem. Right-click on this key and select “Access Rights”. Make sure the Administrators group has "Full Control".

What's the difference between the available AVI splitters?
— Microsoft: Has problems playing incomplete or corrupted files.
— Gabest / MPC internal: Allows you to play most incomplete and damaged files without problems
— Haali: Has problems playing (cropped) files that do not contain the AVI index. Contains a sound switch. This is useful for playing AVI files, having multiple audio tracks in players that do not contain an audio switch directly, such as WMP and Media Center.

K-Lite Codec Pack is a set of tools that allows you to play videos in the best quality. The official website presents several assemblies that differ in composition.

After downloading the K-Lite Codec Pack, many users do not know how to properly work with these tools. The interface is quite complex, and the Russian language is completely absent. Therefore, in this article we will look at setting up this software. For example, I previously downloaded the assembly from the manufacturer’s website "Mega".

All codec settings are done when installing this software. The selected parameters can be changed later using special tools from this package. So let's get started.

Run the installation file. If the program finds already installed components K-Lite setup Codec Pack, you will be prompted to remove them and continue installation. In case of failure, the process will be interrupted.

In the first window that appears, you must select an operating mode. In order to configure all components, select "Advanced". Then "Next".

Profile selection

The next window will be one of the most important in setting up this package. The default value is "Profile 1". In principle, you can leave it this way; these settings are perfectly optimized. If you want to carry out full customization, select "Profile 7".

Some profiles may not have a player installed. In this case, in brackets you will see the inscription "Without player".

Setting up filters

In the same window we will select a filter for decoding "DirectShow video decoding filters". You can choose either ffdshow or LAV. There is no fundamental difference between them. I'll choose the first option.

Selecting a splitter

In the same window, go down below and find the section "DirectShow source filters". This is a pretty important point. A splitter is needed to select the audio track and subtitles. However, not all of them work correctly. The best option would be to choose LAV Splitter or Haali Splitter.

In this window we have marked the most significant points, leaving the rest as default. Click "Next".

Additional tasks

If you want to install additional program shortcuts, then check the boxes in the section "Additional shortcuts", opposite the required options.

To play videos only from the white list, check "Restrict usage to whitelisted applications".

To display video in RGB32 color mode, check "Force RGB32 output". The color will be more saturated, but the load on the processor will increase.

You can switch between audio streams without the player menu by highlighting the option "Hide system icon". In this case, the transition can be done from the tray.

In field "Tweaks" You can customize subtitles.

The number of settings in this window may vary significantly. I show how I have it, but it may be more or less.

Leave the rest unchanged and click "Next".

Setting up Hardware Acceleration

In this window you can leave everything unchanged. These settings work fine in most cases.

Renderer selection

Here we will set the renderer parameters. Let me remind you that this special program, which allows you to receive an image.

If the decoder Mpeg-2, the built-in player suits you, then mark "Enable internal MPEG-2 decoder". If you have such a field.

In order to optimize the sound, select the option "Volume normalization".

Language selection

To install language files and the ability to switch between them, select "Install language files". Click "Next".

We get to the language settings window. We choose the main and secondary languages ​​that meet your requirements. If necessary, you can select another one. Click "Next".

Now let's select the default player for playback. I will choose "Media Player Classic"

In the next window, mark the files that the selected player will play. I usually select all video and all audio. You can select all using special buttons, as in the screenshot. Let's continue.

The audio configuration can be left unchanged.

This completes the K-Lite Codec Pack setup. All you have to do is click "Install" and test the product.

K-Lite Codec Pack is a collection of DirectShow filters and VFW/ACM codecs. They are needed to view and create audio and video files.

The software gets rid of the error that the video format is not supported, installs a player and allows you to encode video and audio using various codecs.

What are codecs

Any information on a computer, including text, photographs, video and sound, can be written as a sequence of zeros and ones. The text can be written down in a very compact form (the entire text part of Wikipedia can fit on a flash drive), while graphics, sound, and especially video take up hundreds or even tens of thousands times more.

Codecs are programs and devices for storing information in digital form(in any format), as well as for compression all this data. All codecs can be divided into two conditional types:

• Lossless compression data (in the so-called lossless-formats). Algorithms similar to those used by archivers when compressing files are used. Video frames encoded in this way will perfectly match the original ones, and will take up less space on your hard drive.
• Lossy audio and video compression ( lossy formats). Most typical example- MP3 music files. Codecs that compress into lossy formats throw out “extra” sounds and image details. Due to the loss of some information that a person most likely will not notice, as well as due to lossless compression algorithms, the file size is smaller than lossless. Lossy encoding has one significant disadvantage: you can overdo it with compression, resulting in files with terrible sound and poor picture.

Among lovers of high-quality sound, debate continues about how best to store music - in lossless or lossy formats. On the one hand, lossless compression allows you to achieve one hundred percent compliance with the original, on the other hand, such an audio library will take up too much space. For videos and photos, the storage problem is also relevant. For example, over the years of its existence, the YouTube video site has changed the codecs with which video stored on servers is compressed several times. As a result, we can now watch video of acceptable quality in 4K resolution, which was impossible to do before, since 4K video simply would not have enough space. hard drives servers.

Types of codecs

There are several types of codecs. Different collections include different types, K-Lite has them all.

DirectShow filters- modern codec format and more. They are divided into three subspecies. Eat capture filters, which are responsible for receiving data from a file with video, music, and even from physical devices like video cameras. Conversion filters allow you to decode and recode data, apply effects, and so on. Rendering (visualization) filters can display video and sound on the screen, speakers, other devices and save to a file.

All DirectShow filters work in a chain, which allows experienced users to organize automatic video processing. For example, you can take a picture from surveillance cameras, display them on different screens, simultaneously adjusting the brightness and contrast on some, take sound from separately connected microphones and save it all into one file with multiple tracks.

VFW standard codecs(Video for Windows). An older codec format that appeared in 16-bit Windows versions before the appearance of the 95th. They are simpler than DirectShow filters and more limited in capabilities - they cannot be used in a chain. Most often, VFW codecs are needed by video editors to open and save (compress) files.

ACM (Audio Compression Manager) codecs. Same legacy standard as VFW, but for audio. Using these codecs, you can open and compress files into MP3, OGG, AAC, etc. formats.

Codecs can be installed on the system so that all programs can use them, or they can be used in separate software. Codecs can also be a separate program. The most typical example is an encoder. You can't watch a video with it, but you can easily convert it to another format. Such programs are not included in codec packs, because The purpose of the packs is to ensure that multimedia files can be opened in any program.

Codec packs are no longer needed to watch videos.

The problem of playing files is no longer as pressing as it was in the days of Windows 98/2000/ME/XP. The Windows 7/8/10 operating systems already contain the necessary components, and if they are not there, there are always players with built-in codecs. Such as powerful

But there are still tasks where codec packs are useful: video editing And working with archived video and sound recordings, where files can be of very different formats

There are less popular codec collections:

• CCCP: Combined Community Codec Pack (discontinued)
• Kawaii Codec Pack (development stopped in 2015)
• Codec Pack All-In-1 ( latest version came out back in 2006)

K-Lite Codec Pack is the most popular collection of codecs and the most useful because it contains not only codecs for opening video and audio, but also for compression, as well as several useful programs and player. K-Lite is regularly updated, new versions are released, while the authors of alternative packs abandon their work.

There are also two universal DirectShow codecs that solve the same problem without installing codecs from different developers - FFDShow(development stopped, included in the “megaversion” of the K-light pack) and LAVfilters(included in any K-Lite versions codec pack).

K-Lite Codec Pack

Where to download K-Lite

All versions are suitable for Windows XP, Vista, 7, 8, 8.1 and 10, both 32 and 64 bit.

There are four variants of the K-Lite Codec package:

1.Basic contains everything you need to play all common video file formats. Simply put, with it you will open AVI, MKV, MP4, OGM and FLV. This option is for those who like a small package with no bells and whistles. It's small, but it solves most problems with opening video files. The universal Lav Video codec is used for playback.

2.Standard contains several additional functions compared to the base version. But the most important thing is that it has a built-in simple and convenient Media Player Classic player. The DirectShow madVR filter is also built-in, which in conjunction with Media Player Classic gives best quality pictures compared to the system filter (when the picture is stretched, the result is b O better clarity).

3. Included Full(full) DirectShow filters have been added compared to the standard version, including the popular universal ffdshow filter. It has not been developed for a long time, unlike LAV Video, but it supports more formats and is able to replace more codecs. Also included in the full version is the GraphStudioNext program. This is a powerful tool for codec and filter developers, which is included in the codec pack so that the user can see which system components are used to open a particular multimedia file.

4. Mega-option is the most complete K-Lite collection. Option for working with video. It contains standards codecs VFW And ACM For video and audio encoding and editing.

What to choose during installation

At the beginning of the installation, you can select a mode: Normal or Advanced. The difference is that in Advanced mode a step for selecting components (“Select components”) will appear. All other sections of the installer will be identical in both modes.

Installation Preferences Section

At the very beginning of the installation, the installer will ask several questions.

Preferred video/audio player- which player to prefer for opening multimedia.

Preferred video/audio decoder- which decoder to prefer (leave LAV video decoder, description will be below).

Create file associations- open files in the selected player.

Install MPC-HC as a secondary player- if another is selected, install Media Player Classic anyway.

Install codecs only for MPC-HC- install codecs only for Media Player Classic (some will still be installed as system codecs for everyone).

Amount of components to install- options for a set of codecs, the middle point is optimal. In Advanced mode, you can refine the set at the component selection step.

Install VFW codecs for video encoding- install codecs for encoding, i.e. creating videos.

Install only 64-bit components- install only 64-bit codecs, 32-bit programs will not see them.

Select Components Section

If you bet Basic or Standard, at this step you can click the “Next” button. There are few components, there is nothing to choose from.

IN Full And Mega There are significantly more codecs. Most likely, you know what you are doing if you choose these versions, but for those who are curious, I will tell you in more detail what is in them.

Right at the beginning of the installation, you can choose whether to install only codecs for playback, whether to install a player, or select your own set (Custom Selection item).

Let's go through all the points.

MPC-HC is a Media Player Classic player. Functional player with many useful options. There are two versions to choose from, the difference is in the bit depth. It’s better to choose only one that matches the bitness of your Windows. Perhaps in the future the authors of the pack will switch to another player, because the development of Media Player Classic seems to have stopped in July 2017.

In chapter DirectShow video decoding filters there are modern codecs for video playback in any players, including standard Media Player and Windows 10 Video Player. The choice is given:

1. Filter LAV Video- standard for Basic and Standart versions of the pack, it supports H.264, H.265/HEVC, MPEG-4, MPEG-2, VC-1, WMV and several other less popular formats. This is the best choice because the project is actively developing, all errors found are promptly eliminated, and in general the codec decodes popular formats without any problems.
2. Filter ffdshow- the decoder is currently outdated, its development has been discontinued. Supports H.264, MPEG-4, MPEG-2, VC-1 and others. The decoder has one interesting feature: in the ffdshow settings you can enable image processing, making it brighter, increasing sharpness, turning it sideways, and so on. If your player does not have filters, but you need them, then video decoding via ffdshow will help you.
3. Xvid- for (de)coding MPEG-4 files. You can choose if for some reason you are not satisfied with LAV and ffdshow, but you can leave the above codecs for processing other formats.
4. Microsoft- the item is needed so that the selected format is still decoded by the codecs built into Windows.

Component selection options affect not so much the choice of what to install, but how codecs should behave. If the package version contains LAV Video and ffdshow, they will be installed in any case, they will simply not be used for formats where a different codec is selected.

Chapter DirectShow audio decoding filters contains codecs for sound playback.

1. LAV Audio- the same as LAV Video, a modern universal DirectShow filter. Supports AC3, DTS, E-AC3, MLP, LPCM, TrueHD, AAC, FLAG, OGG Vorbis, MP1, MP2, MP3, WMA, etc. formats.
2. ffdshow also present in the list, it can play AC3, DTS, E-AC3, MLP, LPCM, TrueHD, AAC, FLAG, OGG Vorbis, MP1, MP2, MP3 and, importantly, uncompressed PCM audio (.wav files). As with video, filters can be applied to audio.
3. AC3Filter- for decoding AC3, DTS, E-AC3, TrueHD, LPCM, AAC and MPEG. This DirectShow filter holds the record for the number of audio processing settings. You can amplify the sound, compress the dynamic range, adjust the delay of individual audio tracks (necessary if the speakers are at different distances so that the sound waves reach the listener at the same time), mix in real time... There are a lot of possibilities and most of them are not needed by the average user.

IN DirectShow source filters You can select video source filters. They are needed not for decoding codecs, but for opening containers - files, inside of which there will be video with sound. For example, the file extensions AVI, MP4, MKV indicate different containers.

1. LAV Splitter- for AVI, MP4, Matroska (MKV), MPEG-TS (MTS), MPEG-PS (PS) and others. When you select LAV Splitter as the standard source filter, you will be able to change audio tracks on the fly in any player via the LAV Splitter icon in the tray.
2. Haali Media Splitter- a once popular filter, it was used to turn on subtitles in unsupported players and switch audio tracks. Now it has been replaced by LAV Splitter as more functional.
3. DC-Bass Source Mod- needed to support OptimFROG files (.ofr .ofs extension) and open tracker music (.it .mo3 .mtm .s3m .umx .xm).

In chapter DirectShow subtitle filter there is only one point DirectVobSub. This filter will allow you to automatically connect subtitles from video files of the same name. It is not relevant now, because popular players already support subtitles stored both inside video files and external ones with the .srt extension.

Chapter Other Filters includes two DirectShow visualization filters for displaying images in players.

1. MadVR- a very powerful filter that allows you to qualitatively scale the image and, what is important, make the frame change smooth.
2. Haali Video Renderer- a filter whose development has long been discontinued, does not really work, it is unclear why it was included in the K-Lite Codec Pack.

IN VFW video codecs There are codecs of the Video for Windows standard. If you use old video editing software or VirtualDub, then you need them.

1. ffdshow VFW interface- VFW part for ffdshow, which I mentioned above. Allows you to save in FFV1, HuffYUV, DV and MJPEG.
2. Xvid- a free compatible alternative to the once popular DivX (MPEG-4).
3. x264VFW- for encoding video in the H.264 format, which is the next evolutionary step after MPEG-4.
4. huffyuv- lossless codec for encoding and decoding video files of the same format.
5. Lagarith- modified huffyuv, compresses stronger, no data loss either.

ACM Audio Codecs needed for audio compression.

1. MP3 (LAME) is a popular MP3 codec for audio compression in programs such as VirtualDub. It will only be installed if there are no other MP3 codecs in the system.
2. AC3ACM- for AC3 format. AC3 has two features: there can be many audio tracks and the technology is protected by patents. Because of this, many players on phones do not support the AC3 format. There are no problems with this in Windows players.

In chapter Tools there are utilities.

1. Codec Tweak Tool- a program for reconfiguring codecs and resetting their settings. In it you can replace LAV with ffdshow without reinstalling the K-Lite Codec Pack.
2. MediaInfo Lite- to display detailed information about codecs inside multimedia files.
3. GraphStudioNext- a very powerful utility for DirectShow filter developers. In the K-Lite Codec Pack, it is most likely included because of the function of viewing which filters are used when opening a particular file.
4. Haali Muxer- a utility for packaging individual audio and video files into Matroska containers (.mkv).
5. VobSubStrip- a tool for solving a specific task: extracting subtitles for a specific language from files in .idx and .sub formats.
6. FourCC Changer- a program that changes the label about the codec used in video files. This is useful if the required codec is not used when opening a video file.

IN Explorer shell extensions Windows Explorer extensions are located.

1. Icaros ThumbnailProvider allows you to see the contents of video files in popular formats in thumbnail view.
2. Icaros PropertyHandler allows you to view the width, height, frame rate, duration in the properties of files with extensions .flv, .mkv, .ogm, .rmvb, .webm, .ape, .flac, .mka, .mpc, .ofr, .opus, .spx , .tak, .tta, .wv.

IN Miscellaneous there are two options - Detect broken codes And Detect broken DirectShow filters, which include checking codecs and DS filters already installed in the system. If something is wrong with them (damaged or missing files and entries in Windows registry), they can be deleted. The same function is available in Codec Tweak Tool.

Additional Tasks and Options Section

In the next step, the installer will clarify several settings.

Their number will differ depending on your choice in the previous step. Most of the settings are clear based on their names; I’ll tell you only about the most important ones:

Reset all settings to their defaults- reset all codec settings. Useful if you update the codec pack from old version or an alternative one has been installed.

Windows Media Player: register supported file formats- standard Windows Media Player will open formats supported by installed codecs.

Optimized preferred decoders settings: The installer will adjust the system codec settings to optimal values, according to the authors of K-Lite Codec Pack. You can later change them manually using the Codec Tweak Tool.

Add to Explorer context menu- a new “MediaInfo” item will appear in the right-click menu to easily open video and music files in the MediaInfo program.

Hardware acceleration section

Here you configure hardware acceleration of video decoding. This is important for watching high definition movies.

You can select the decoding method (universal and problem-free - DXVA2 copy-back), and also enable acceleration only in the Media Player Classic player (item “Only use hardware acceleration in combination with MPC-HC”).

MPC-HC configuration section

Appears when you select Media Player Classic.

An important option here is the choice of video renderer (“Video renderer”). If you bet madVR, choose it, otherwise the optimal one will be Enhanced Video Renderer (Custom Presenter).

Preferred language(s) for audio and subtitles section

Here you can set your preferences for choosing an audio track. The settings in the screenshot below are the most universal for a Russian-speaking user.

If there is a Russian track in the video, it will be included. If not, then English and subtitles in Russian (if available).

File associations section

Allows you to specify which player to use to open audio and video files.

Due to the peculiarities of assigning file associations in Windows 10, this step may not affect the choice and you will have to assign programs manually through Control Panel - Default Applications.

Depending on the checked boxes, additional steps will appear where you can select in detail the associations of the program with file types.

Audio Configuration Section

After installation

Restart your computer, otherwise some codecs will not work correctly.

If you need to change any codec or filter settings, there will be a K-Lite Codec Pack folder in the Start menu with shortcuts to settings and utilities.

Do you turn on a movie, but the player gives an error? Or does the video play, but without sound? Do not rush to panic and think that there is something wrong with the computer - it simply does not have the necessary codecs. The problem can be easily fixed! Below you will find detailed and clear instructions on installing video and audio encoders and learn several valuable life hacks for working with multimedia.

Why are codecs needed?

It is possible that the term “codec” is not familiar to you, and it is not surprising - the user does not need this information to enjoy video or audio. However, when playback errors occur and the system requires you to install something, knowledge will clearly be useful.

Speaking in simple language, codec is a small encryption program that is included in any operating system. Not only computers, but also cameras, phones and other devices are equipped with such software. Their key task comes down to encoding data when writing and opening files. The quality of the result depends on how “quality” the codec encrypts and translates information.

Codecs are involved in encrypting and decrypting data when shooting and playing video.

Interesting fact! Modern cameras have the ability to shoot 60 or even 120 frames per second. Ideal for action shots, but other times you're simply capturing 60 identical frames. This means that in a minute of recording you will take 3600 frames, most of which are “extra”. Video codecs are built into the device's OS to find duplicates and erase them. This reduces the size of the video, making it suitable for viewing on small devices.

Quick Installation and Upgrade Guide

When purchasing a computer (or other device), you buy it with a set of decoders that will allow you to correctly play the most popular video and audio extensions. However, if you are trying to play a video or audio track in a non-standard format, you may need “extra” options.

If you are a Windows XP user, you can view the list of installed codecs by clicking on the “My Computer” shortcut and selecting “Properties”. Open the Hardware tab and go to the Device Manager section. In the line “Sound, game, video devices”, find the arrow and click on it. If you are a Windows 7, 8 or 10 user, launch Windows Media Player, hold down the ALT key and in the menu that appears, find the “About” item. Click on the hyperlink “Information about technical support» – and the browser will display a page listing codecs.

Immediately after clicking, a tab with a table of supported formats will open in the browser.

If the built-in options are not enough and the player asks new video codec to open - don’t get upset and don’t give up. Decoders can be easily found on the Internet and downloaded completely free of charge. Different formats require their own encoders; installing them one by one is not the best solution. It’s much easier to download a single package.

The most popular set is K-Lite Codec Pack. The package is good not only because of its impressive list of supported formats, but also because it works on all versions of Windows, starting with XP, and is compatible with most media players. To install codecs on your PC, follow these step-by-step instructions.

☛ №1. Go to the official K-Lite Codec Pack website, go to the download page and select the product version. More than enough for most users Basic versions(the Mega option is needed only for those who require the finest settings of the media player), so feel free to click on Download.

Download basic set codecs on the K-Lite Codec Pack website

☛ №2. After downloading, run the distribution. In some cases, especially on new versions of Windows, the system may issue a warning (see picture). There is no danger in the set of decoders, especially those downloaded from the official resource, so click "Do it anyway".

☛ №3. Follow the prompts of the Installation Wizard. The standard installation parameters are set by default, the boxes are checked and you don’t need to change anything. Click Next until you reach the language selection window for audio and subtitles. Check that the primary language is Russian.

Make Russian the default language

☛ №4. Afterwards the Wizard will offer to mark video and audio decoders for loading. You can uncheck those that are already selected. If you don't need audio decoders, click Select none, and then - Select all videos.

Uncheck the boxes only when you are sure which codec you already have installed

☛ №5. When the final installation window appears, all you have to do is click the button Install and wait for the process to complete. Click Finish- and you're done!

Follow the prompts of the Installation Wizard, and the codecs will be ready to download in a couple of minutes

Now you can easily enjoy any media files!

The technology is constantly being improved, new formats and new encoding requirements appear. However, you don't have to worry, as updating codecs on Windows 7 and other versions of the system is very simple. All that is required is to periodically install the latest version of the package on top of the previous one.

Alternative way to solve the problem

Another way to forget about format incompatibility is to install an editor that supports the conversion function. Such software will not only allow you to change the extension and codec, but also significantly - correct colors and lighting, cut out unnecessary things, add effects.

"VideoMONTAZH" supports both popular and more rare extensions. You can work with both short clips downloaded from the Internet and bulky movies downloaded from DVDs. To change the codec, you need to add a video to the slide bar, go to the tab "Create" and select the appropriate conversion option from those offered.

Choose a new, more popular video format

In addition, using the video editor, you can:

• glue together several passages, regardless of their extensions;
• shorten the duration of a track, change the playback speed;
• adjust tone and color balance;
• improve the image using built-in effects;
• add captions, photographs or clipart on top;
• replace or add sound.

The editor will allow you to quickly improve your video

At the end, you have complete control over the quality of the result. Moreover, the software allows you to easily burn video to a DVD, upload it to the Internet, or save it for viewing on mobile devices.

Now you know how to install codecs quickly and for free. However, you will get much more if you decide. This life hack will allow you not to track updates to software packages and always have access to view any files. In addition, you will be able to transform and create bright videos, because “VideoMONTAZH” includes all the necessary tools.

If, when installing a codec, you found a window with a choice of profiles, and you want to customize it as conveniently as possible “for yourself,” then you will have to thoroughly understand all the extensions offered to you.

From the drop down menu select Profile 7: Lots of stuff and at the bottom you will find great amount switches and checkboxes. You, of course, can leave everything there as it is and continue installing your codec, or you can change some settings.

Here is a description of some of them that are most important to users.

• Player - in case you use other players. Do not uncheck this sub-item, you will then be able to associate the files during installation with any of your favorite players.
• Flash Video - FLV is a special bitstream that is a special variant of a well-known video standard. This format is supported by most codecs. Select it in order to play these files.
• VP7 - but it’s better not to uncheck this codec. It is used by many sites to play videos on the Internet.
• Process raw video - this option is usually disabled. This format supports raw video that is taken directly from the sensor, or video that has not yet been fully processed (usually to avoid loss of information). In this form, you receive video from some types of video cameras, recorders, and so on.
• In the DirectShow audio decoding filters sub-item you will select audio filters. In almost all cases, ffdshow is preferable.
• MP1, MP2, MP3 are familiar compressed audio files. Leave it unchanged.
• AAC is a special audio format for YouTube, iPhone, iPod, iPad, Nintendo DSi, iTunes and so on.
• Other audio formats - in this column we select preferences for other audio formats.
• Process uncompressed audio (PCM) is uncompressed audio processing and is disabled by default.
• For avi, matroska, mp4 and flac formats, use standard settings, they are the best by default.
• The Tools column contains all the tools. Check the boxes next to all the tools, you will figure it out as you go, many of them may be needed completely unexpectedly. The set of tools will not burden the program or your computer at all.
