Contains both 32-bit and 64-bit codecs.

There are different variants of the pack. From small to large. You can pick the one that fits your needs.

The pack implements special blacklists for some of its included DirectShow filters. These blacklists are used to avoid compatibility issues with certain applications and games. Helpdesks and other support staff often recommend the K-Lite Codec Pack because of its abilities to fix problems and its features to ensure optimal compatibility.

Advantages of the pack compared to installing codecs manually:

The best available codecs are already selected for you by codec experts. There is no need to figure out what you need.
Installation is simpler, quicker, and more organized.
It is much easier to keep all your codecs up-to-date. There no need to keep track of updates to individual components.
Components are automatically configured to work together in perfect harmony. Something that is not easily achieved if you would install everything manually. Certainly not if you use a mix of different splitters and decoders.
Better default settings.
More configuration options during installation. This is particularly useful for unattended installs.
The pack provides extended video thumbnail generation functionality for Windows Explorer. All popular video file formats are supported.
Adds support for showing file properties such as duration and width/height in Windows Explorer for FLV and MKV video files.
The pack automatically configures Windows Media Player and Media Center to recognize all common audio and video file formats, so that such files show up in your media library. Normally this would require all kinds of manual Registry tweaks.
The pack includes very useful tools for managing and configuring the installed codecs.
