MFPKEY_FORCEMEDIANSETTING Property

  • Artigo

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.
