MFPKEY_FORCEMEDIANSETTING Property
Specifies whether the codec should use median filtering during encoding.
Constant for IPropertyBag
g_wszWMVCForceMedianSetting
Data Type
VT_BOOL
Default Value
FALSE
Remarks
Median filtering tells the codec to ignore noise and grain when calculating motion between frames. This can improve the quality of very noisy video, but can lead to motion trails (also known as trailing artifacts) when applied to clean source video.
By default, the codec uses internal logic to determine whether median filtering should be used. If you set this property, that logic will be overridden.
Note
This filter is not the same as median blur filters found in many video editing and post-processing applications.
