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 driver 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.
