Constant for IPropertyBag

g_wszWMVCMotionMatchMethod

Data Type

VT_I4

Default Value

0

Remarks

This property may be set to one of the following values.

Value Method used
0sum of absolute differences (SAD)
1Hadamard
-1Macroblock-adaptive.

 

The sum of absolute differences (SAD) is a faster but less accurate method than the Hadamard transform. The Hadamard transform is more accurate but computationally intensive. The macroblock-adaptive mode provides a reasonable compromise between the two methods by dynamically choosing between the two transforms, selecting the Hadamard transform only when appropriate.
