Microsoft DirectX 9.0


This topic applies to Windows XP only.

The DecimateInput property indicates whether the Video Mixing Renderer (VMR) will decimate the video (that is, reduce the native video size) before processing it.

This property is currently not supported.


objMSVidVideoRenderer.DecimateInput As Boolean


This property has no parameters.

Error Codes

If the property fails, an error is raised and Err.Number is set to a value other than zero.

Return Values

Returns True if the VMR will decimate the video, or False otherwise.


This property should be set to True when the native video stream is HDTV but the system monitor is set to a lower resolution. This prevents the VMR from doing unnecessary work by processing the video at high resolution and then shrinking it.

This property is read/write.
