Downside of this method is that doing this conversion in software increases CPU usage. ATI removed it in 9.2 and newer.įorcing ffdshow to output RGB32 can help prevent luminance level issues. Note: the tweak only works with driver version 9.1 and older. Te UseBT601CSC setting is the one related to luminance levels. Several ATI driver tweaks can be found here: It already does that by default for HD video. With the tweak applied, the driver will convert TV levels to PC levels for SD resolution video. The ATI driver requires a Registry tweak. NVIDIA Control Panel -> Video & Television -> Adjust video color settings -> Select 'With the NVIDIA settings' -> Advanced tab -> Set Dynamic Range to 'Full (0-255)'.

Since version 177.84, the NVIDIA drivers have an option for configuring the luma range. Method #1: Adjusting graphics driver settings If you are using a CRT TV, then read the comments at methods 2 and 3. The methods below assume that you are outputting the video to a PC monitor or LCD TV, meaning a device that needs full range luminance (0-255). For most people only when playing low resolution videos. Levels are usually wrong when using the VMR-9 or EVR CP renderers. Many factors play a role, so it is not possible to give a list of combinations that always gives wrong levels for everyone. In that case dark colors are displayed too dark, and light colors are displayed too bright. The opposite is also possible, but more rare. The video looks washed out and the colors are not vivid. It can go wrong with certain combinations of video renderers, video resolutions, and graphics driver settings. When converting a YUV colorspace to RGB, the correct standard (BT.601 or BT.709) must be used and the correct range (TV or PC levels) must be used. There are two commonly used ranges: 0-255 (aka PC levels) and 16-235 (aka TV levels). Unfortunately this range is not always the same. For high-definition TV the standard is BT.709.

For standard-definition TV the standard is BT.601. There are two standards for the encoding of luma. YUV is a family of color spaces (YV12, YUY2, etc), that encode color information (chroma) separately from brightness information (luma). I'll update the information below to include your wisdom.ĭigital video is typically encoded in a YUV ((VS.85).aspx) format. The purpose of this topic is to centralize the collective knowledge of the Doom9 community regarding this subject. It is a subject that gets discussed over and over again. Wrong levels is a common playback problem.
