Codec Tweak Tool

This tool is a Swiss army knife for managing codecs and codec settings. Below is a short overview of the functionality that this tool has to offer. Detailed help is available for each individual function. If any of the information below is unclear or insufficient, then please let us know.

Fixes

The first two fixes detect broken VFW/ACM codecs and DirectShow filters. This will perform a scan of the Windows Registry looking for invalid references to codecs and filters. Such invalid references are Registry keys that for example point to non-existing files. Those keys can for example get left behind when a codec is not properly uninstalled. The Codec Tweak Tool can remove the invalid references.

The third fix will re-register the base DirectShow filters of Windows. This is helpful if they somehow got removed.

The fourth fix is one for a specific sound related problem. If certain Registry keys are missing, sound will not work in most programs. This fix will restore those required Registry keys. This fix is only available when this specific problem is detected. Sound problems can have many different causes. If you are experiencing a sound problem that affects multiple programs, then the first thing you should try is to re-install your sound driver. That often fixes sound related problems.

Generate Log

This allows you to generate a very detailed list of all installed codecs installed on your computer. It can also include useful information about your system. All this information can be very useful for problem solving purposes.

Reset Settings

Resets settings to recommended default values for many popular codecs and DirectShow filters.

Backup Settings

This creates a backup of your current settings. The settings will be saved in a folder of your choosing and consists of one or more files. You can restore those settings at any time using this tool.

Settings from the following items (if installed) are included in the backup:
Media Player Classic, ffdshow, LAV Filters, Haali Media Splitter, AC3Filter, DirectVobSub, madVR, Xvid, x264VFW, huffyuv, CoreAVC, CoreVorbis, CoreAAC, MONOGRAM AAC decoder, Gabest MPEG-2 decoder, DScaler5, VP7, and more.

Restore Settings

This replaces your current settings with the settings from a previously created backup.

DirectShow Filter Configuration

This allows you to access the configuration interfaces of several popular DirectShow filters.

VFW Codec Configuration

This allows you to access the configuration interfaces of a few commonly used VFW codecs.

Speaker Configuration

This allows you to configure audio output settings for several popular audio decoders.

DirectShow Filter Management

This allows you to enable and disable DirectShow filters. This can for example be useful for testing purposes, or simply to disable redundant filters, or to switch between two similar filters.

Other filter managers are usually only capable of disabling filters. This tool also allows enabling filters because it remembers which filters you have previously disabled. It also gives more fine-grained control over a few multi-purpose filters, such as Haali Media Splitter, allowing to also disable it partially.

This page does not show every single filter installed on your system. It only shows ones that it has been programmed to detect. Currently that includes more than 200 commonly used filters. If there are any additional ones that you would like to see added to this list, just let us know.

Some filters from the pack may be listed as disabled. This is normal. Not everything is enabled by default. Do not blindly enable everything, unless you have a good reason for doing so.

ACM/VFW Codec Management

This allows you to enable and disable ACM and VFW codecs.

This page does not show every single codec installed on your system. It only shows ones that it has been programmed to detect. Currently that includes more than 50 commonly used codecs. If there are any additional ones that you would like to see added to this list, just let us know.

Preferred Splitters

This allows setting specific source filters (a.k.a. splitters) as preferred for specific file extensions. This is particularly useful if you have multiple source filters installed for handling a certain container format.

The choice "System default" means that no specific source filter is forced as preferred. In this case your player will use the source filter that has the highest merit, which often is one of the filters that could also be chosen as preferred. System default therefore does not necessarily mean a standard filter that comes with Windows.

An important note for Windows 7 users: these settings only apply to players that use the DirectShow framework. Windows 7 contains a new playback framework called "Media Foundation" that is used by the Microsoft players (WMP and Media Center) for playback of certain files types, such as MP4, MOV, and M2TS. The Win7DSFilterTweaker tool has tweaks for disabling Media Foundation in case you prefer to use DirectShow.

Thumbnail Settings

Here you can enable and disable thumbnail generation in Windows Explorer for various video file extensions.
There also is an "Options" button which gives access to a few options and tweaks specific to thumbnails. For example a way to clear the thumbnail cache. Also some tweaks for thumbnail appearance.

Various Tweaks

Several configuration options for a few DirectShow filters that don't have an easily accessible interface for those options. This button is disabled when none of the available tweaks is relevant for your system.

DMO Management

This allows you to enable and disable a few DirectX Media Objects. DMO are similar to DirectShow filters.
This functionality is only available on Windows XP.

Available command-line parameters

To remove broken codecs and filters use:
codectweaktool.exe /fixes /silent
(Administrator privileges are required)

To reset settings to defaults use:
codectweaktool.exe /resetsettings /silent

Unlike past versions this one removes more registry enteries. It wiped out my Vegas 11 program by removing Sony related files. Fortunately, I backed up the registry before running the program and was able to get back Vegas functionality. I went back to the previous version which did no harm. Before removing anything, it should give you a yes or no choice.

Why can't the file builds be consistent? Some builds are a single file with an icon of crossed hammer and wrench. Some builds are 3 files with no custom icon. Why the sloppy 3-files versions?

It saved my butt! My video editor, VS Pro X5, suddenly could not play back a series of clips or an individual clip in "Project Mode, albeit it fumctioned in individual "Clip Mode" for individual clips." It looked to me like a codec problem. So, I ran the Codec Tweak Tool. After that, VS Pro X5 functioned as it should without error. Also, it backed up my codecs. A good must have tool.

dear cal_tony I guess you have problem with windows
by the way for me wordpad.exe is in this directory
C:\Windows\winsxs\amd64_microsoft-windows-wordpad_31bf3856ad364e35_6.1.7601.17514_none_8be07ea283850f02
and this one
C:\Windows\winsxs\wow64_microsoft-windows-wordpad_31bf3856ad364e35_6.1.7601.17514_none_963528f4b7e5d0fd

Evidently it has a help file but when I hit the help button all I get is that it can't find wordpad. I put wordpad in the window folder, windows system 32,windows system and the folder that the program is in. Don't have any idea where it expects to find wordpad.
Other than that seems to work just fine just using the prechecked boxes

A changelog for new releases would be nice; what needs to change several times a year in a tool that does mostly registry and Directshow merit-based work?. Other than that an excellent program that behaves exactly as it promises to in fixing many codec configuration problems.
