MFPKEY_MOTIONMATCHMETHOD Property
Specifies the method to use for motion matching.
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 |
|---|---|
| 0 | sum of absolute differences (SAD) |
| 1 | Hadamard |
| -1 | Macroblock-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.
