[edit] General Encoding Settings
Basis of all video encoding settings is the Windows Media Codec 9. Since LC and plasma displays do not use interlaced scanning a progressive output (without field order), i.e. full screens as well as the usage of square pixels are recommended. In case of an varying number of fps in the source Material it should be taken over to prevent optical jerking. For all WMV-output standards a stereo audio output using the Windows Media Audio Codec 9.2 at 192kbps (constant bitrate), a sample rate of 44.1kHz and a sample size of 16Bit is recommended.
