Windows 10 Tips

Thursday August 13th 2015

Windows 10 has been officially released two weeks ago and statistics show that a lot of you are already using it.

The current version of the K-Lite Codec Pack is fully compatible with Windows 10. In fact, the codec pack has been compatible for a long time already.

If WMP does not show any subtitles:
Codec Tweak Tool > Media Foundation > disable for .mp4 and .mkv

If you are having problems with video playback on Windows 10, then it is most likely because of your graphics or sound driver. Visit our forum if you have any problems and need help. We expect hardware manufacturers to improve and fix their drivers in the coming weeks/months. Windows 10 should update them automatically.

There are lots of known problems regarding hardware acceleration with the current Intel and AMD drivers. We recommend to use software decoding until those drivers are fixed.

Tip: Microsoft has released a tool that you can use to prevent faulty drivers from being re-installed by Windows Update. You can get it HERE. This is useful if your have trouble with the latest drivers.

Another recent known cause of playback failure and crashes is EVGA PrecisionX.

DTS-HD Master Audio

Tuesday March 24th 2015

Good news. The LAV Audio decoder included in the latest version of the K-Lite Codec Pack now supports decoding DTS-HD Master Audio. Previously no free or open source decoder existed for that audio format.

As usual K-Lite is the first pack to offer this new functionality. Other packs and players like VLC are (much) slower to update.

A big thanks goes to foo86 (developer of dcadec) and Hendrik Leppkes (developer of LAV Filters) for making this possible.

NVIDIA 344.11 driver bug

Tuesday September 23rd 2014

The latest NVIDIA graphics driver has a bug that can cause playback to fail for files that contain 10-bit H.264 video. This type of video is not very common, it is mostly only used for Anime videos. There is a simple workaround to avoid the problem: disable the P010 output format in the settings of LAV Video decoder (or ffdshow if you still use that). Update: the 344.48 and newer drivers works again with EVR, but is still broken with a few other renderers.

Tips for improving video quality

Thursday August 15th 2013

This is a tip for anyone who has an Intel or AMD/ATI graphics card. These manufacturers enable certain video 'enhancement' features by default in their drivers. The problem is that those features actually reduce quality instead of making things better.
It is thus recommended to disable these features. This should improve both quality and performance. You can find the relevant options in the control panel of your graphics card. You can usually find a shortcut to that control panel by right-clicking on your Desktop. Options that you should disable are: "Noise reduction", "Adaptive contrast", "Dynamic Contrast", "Edge Enhancement", and "Skin Tone Enhancement". The number of options and their names can vary depending on the manufacturer and driver version. Visit our forum if you need assistence.
If you got a powerful graphics card then you could also try madVR in combination with MPC-HC. madVR is an advanced video renderer that is able to produce better quality than the standard renderers from Windows. Configuring madVR for optimal quality/performance can be a bit complex for novice users, so we only recommend using it if you got a decent amount of computer knowledge.

Win7DSFilterTweaker 5.9

Saturday May 4th 2013

This is a useful little tool that allows you to configure your preferred DirectShow filters for decoding for example H.264, MPEG-4 and VC-1 video in Windows 7 and 8. This makes it possible to use third party decoders instead of the native decoders that come with Windows.
