Basic

Small but extremely powerful!

Already contains everything you need to play all common audio and video file formats.

Supports playback of:

• AVI, MKV, MP4, FLV, MPEG, MOV, TS, M2TS, WMV, RM, RMVB, OGM, WebM
• MP3, FLAC, M4A, AAC, OGG, 3GP, AMR, APE, MKA, Opus, Wavpack, Musepack
• DVD and Blu-ray (after decryption)
• and many more audio and video formats!

Provides lots of useful functionality, such as:

• Subtitle display
• Hardware accelerated video decoding
• Audio bitstreaming
• Video thumbnails in Explorer
• File association options
• Broken codec detection
• and much more!

Note: the Basic version does NOT include a player.
You need to use it together with an already installed DirectShow player such as Windows Media Player. For playback issues with WMP please read our F.A.Q. for solutions.

We recommend using K-Lite Standard, which includes MPC-HC, which is a very good player.

Standard

Same as Basic, plus:

• Media Player Classic Home Cinema (MPC-HC)
  This is an excellent player. Highly recommended!
  It provides high quality playback and many useful options.
• MediaInfo Lite
  This is a tool for getting details about media files.

This is the recommended variant for the average user. Use this if you don't know what you need. It already contains everything that you need for playback. The extra components that are included in the larger versions provide no benefit for the majority of users.

Full

Same as Standard, plus:

• MadVR
  An advanced video renderer with high quality upscaling algorithms.
• DC-Bass Source Mod
  For decoding OptimFrog and Tracker audio files (very rare formats).
• Plugin for 3D video decoding (H.264 MVC)
  Note: this requires using MPC-HC with madVR, and also a compatible graphics driver. Recent NVIDIA drivers no longer support 3D video (but you could try '3D Fix Manager').

Mega

Same as Full, plus:

• GraphStudioNext
  A tool for creating and testing DirectShow graphs.
• A few ACM/VFW codecs such as x264VFW and Lagarith
  This type of codec is used by certain video editing/encoding applications for working with AVI files. For example VirtualDub.
  These codecs are not used or needed for video playback.
  Important note: The K-Lite Codec Pack does not expand the import abilities of professional video editors such as Vegas Movie Studio or Adobe Premiere. Those applications often only support importing a small set of file formats, and do not support using the type of codecs that are included in the codec pack (DirectShow/VFW). Modern editors often only use their own internal codecs or only support external codecs of the Media Foundation type.

And a few extra optional DirectShow filters:

• ffdshow audio/video processor
  Provides some filters for manipulating the decoded audio and video.
• ffdshow audio/video decoder
  An alternative choice for LAV Audio/Video decoder.
• AC3Filter
  An alternative choice for LAV Audio decoder.

Important note: The extra filters mentioned above are not installed by default. We also do not recommend using these outdated filters. They are only included for a tiny group of people who have a reason for using them. We strongly recommend to use the default decoders from the pack. Those are better.

Important note: All the extra functionality included in Mega is only useful for a small group of people. It does not provide playback capability for any additional audio or video formats. If you are only interested in playback, then Full version is already enough for you.

Update

Additional updates for the latest version of the codec pack.

This is not a stand-alone installer. This update requires that the latest version of Basic/Standard/Full/Mega is already installed.

Beta

Beta versions contain the latest updates and improvements, but they have not yet been tested as well as normal releases.

For experienced users who like to try out the latest stuff and want to provide feedback.

Beta versions are available for Basic/Standard/Full/Mega.
