IWMEncAudienceObj.VideoImageSharpness

Windows Media Encoder SDK banner art

The VideoImageSharpness property specifies and retrieves a value indicating the video image quality.

Syntax

IWMEncAudienceObj.VideoImageSharpness(iRenderSiteIndex) = Long
Long = IWMEncAudienceObj.VideoImageSharpness(iRenderSiteIndex)

Parameters

iRenderSiteIndex

[in]  Integer containing the audience stream index. Because an audience can only contain one stream of each type, iRenderSiteIndex must be zero.

Property Value

A Long between 0 to 100 indicating the quality of the video image.

Remarks

The VideoImageSharpness property is used for constant bit rate (CBR) mode. A lower value results in smoother image movement and a higher frame rate, while a higher value results in a clearer image and a decrease in frame rate.

Example Code

' Create a WMEncProfile2 object.
  Dim Pro As WMEncProfile2
  Set Pro = New WMEncProfile2

' Load a custom profile. REPLACE THE FILE NAME.
  Pro.LoadFromFile "C:\Profiles\CustomProfile.prx"

' Create an IWMEncAudienceObj object, selecting the first audience (0)
' in the profile.
  Dim Audnc As IWMEncAudienceObj
  Set Audnc = Pro.Audience(0)

' Retrieve a value indicating the video height in pixels.
  Dim lVidSharpness As Long
  lVidSharpness = Audnc.VideoImageSharpness(0)
