All features / Full description

This pack includes both 32-bit and 64-bit codecs.


Media Player Classic Home Cinema (MPC-HC) [version]
This is an advanced player with many useful options. We recommend using this player for video playback.

DirectShow video decoding filters:

LAV Video [version 0.65-36-g6b6bc]
This decoder supports a large number of video formats.
MPC DXVA Video Decoder [version]
For hardware accelerated (DXVA1) decoding of H.264 and VC-1 video on Windows XP.

DirectShow audio decoding filters:

LAV Audio [version 0.65-36-g6b6bc]
This decoder supports a large number of audio formats.

DirectShow source filters:

LAV Splitter [version 0.65-36-g6b6bc]
This splitter supports a large number of audio and video file formats.

DirectShow subtitle filter:

DirectVobSub [VSFilter version] [xy-VSFilter version]
DirectVobSub is a filter for displaying subtitles. It supports all common formats such as SRT, SSA/ASS, PGS, and VobSub.
Your subtitle file should have the same filename as your video file. It should also be in the same folder as your video file. Then the subtitles will automatically be loaded and displayed during playback.
Example: MovieName.avi +
xy-VSFilter has slightly better performance for complex animated subtitles compared to regular VSFilter. However, it also has some known stability issues with a few applications. For example Winamp and Windows Media Center. That is why regular VSFilter is used by default.

Other filters:

madVR [version 0.88.16]
Excellent video renderer that can be used as an alternative for the video renderers that Windows offers.
Recommended for expert users with high-end graphics cards.


Codec Tweak Tool [version 5.9.9]
This tool is essential for the management of codecs and settings. It has many useful features such as:
* Detect and fix several common problems
* Reset settings
* Backup and restore settings
* Configure preferred splitters
* Enable/disable any of the installed codecs and filters
* Manage thumbnail settings
* Generate detailed log with system information and list of installed codecs
* Configure preferred decoders on Windows 7/8/10
* Tweaks to disable Media Foundation and certain other MS codecs on Windows 7/8/10
MediaInfo Lite [version 0.7.75]
This tool can analyze a media file and show detailed information about it.

Explorer shell extensions:

Icaros ThumbnailProvider [version 2.3.0]
This shell extension is used for generating video thumbnails in Windows Explorer. It supports all common video formats.
Icaros PropertyHandler [version 2.3.0]
This shell extension allows displaying file properties such as duration, width, height, and framerate in Explorer. It supports the following audio and video file formats: .flv .mkv .ogm .rmvb .webm .ape .flac .mka .mpc .ofr .opus .spx .tak .tta .wv

I really think Videohelp should update their reviews and score. This software deserves more than the rating. All the reviews and ratings are really old and not really applicable anymore.

I have been using KLCP for a couple of years now, and I must say, they have come a long way. I agree that all the old reviews were correct in their time, the software had issues. You used to get somewhat frequent clashes with other software, or crashes or etc. But in the recent times, the software is REALLY stable. Since the past year, I have a hard time remembering the last time I had crashes or issues with the software. They are also probably the only codec pack to update very frequently. That being said, it could be good or bad depending on how you look at it, sometimes latest filters and such might give you problems. I have not personally experienced anything thing in the recent times though.

The installation phase at expert settings is a treat. It gives you so much control over all options (what filters you want to install, file association etc.). Once done, it play pretty much everything you throw at it. Never had any issue with any playbacks. I used to use ffdshow but with the introduction of LAV into KLCP, I switched because I read that LAV was better. The only issue I ever faced was that when playing Darksiders, the cutscenes would skip because KLCP (with LAV) clashes with the game and it ends up getting skipped. A number of people faced that problem, and the only solution seemed to uninstall KLCP temporarily. It could potentially repeat for other games, but again, I did not face anything personally.

The old versions used to come with the regular MPC but the newer ones come with MPC-HC. It is overall the same though, very minimalistic in terms of design but without sacrificing any functionality. It ensures that the application does not take too much RAM.

Now for the downsides, first off, WARNING: The application is a "bundleware". It comes with toolbars and homepage changer. DO NOT, I repeat, DO NOT, keep clicking "Next" blindly. You have to "Decline" the two offers otherwise you will end up with toolbar and your homepage changed to Bing or whatever it was. This itself is a big negative for me, when applications come bundled with stuff like this. But at least it gives you an option to skip it.

Now the second one is not really major, but it would have been nice if the application came bundled with a set of encoders for Ripping/Converting multimedia files. Foobar comes with a really excellent Ripping and Converting software and VLC comes with it too. Not that I take off points for this statement but it would have been nice nevertheless. I am guessing it has to do with MPC-HC and not the pack itself.

Apart from this, I have no other issues. I would highly recommend this to anyone who is looking for a decent, minimalistic player which can play everything, provided if you skip the advertisements during installation.

Please install Full version instead of Mega version. Then install MPC-HC seperately!!

If your OS not working for this Mega Version....

First, I have to say this is the BEST code pack ever and it should be rated higher! It's free and also works better than the ones that charged. The K-Lite Codec Pack play just about every codec files. I mostly use it to watch divx coded files. After installing it, I also have no problem using Windows Media Player 9 to watch encoded divx file unlike someone previously mentioned (maybe he should try new vers and make sure his Window Media Player 9 is updated?). I highly recommend however using the cool and slick ^^ BSPlayer instead for those of you who dislike the Media Player Classic interface or prefer a much cleaner looking player then Windows Media Player 9. BSPlayer can be found in the the K-Lite Mega Codec Pack vers 1.25 which can be downloaded from the main website link.

The K-Lite Mega Codec Pack vers 1.25 is essentially a K-Lite Codec Pack 2.41 Full version with additional features such as QuickTime Alternative 1.42, Real Alternative 1.32, BSplayer 1.22.817 and FFDShow build 2005-02-16. By the way, all these features can be installed optionally.

For me, the installation process went through smoothly. Uninstalled seems to work just as well for the full program or features otherwise such as such as QuickTime Althernative and Real Alternative. I have to say though, these features are really worth keeping. Once you installed you will no longer need QuickTime Player or the overly 'bloated' Real Player.

This is a awesome tool! 10 all the way! ^^
