Specifies whether the codec should use the in-loop deblocking filter during encoding.
Constant for IPropertyBag
g_wszWMVCLoopFilter
Data Type
VT_BOOL
Remarks
The in-loop filter is a deblocking method that is applied during both encoding and decoding, to reduce blocking artifacts at encoding time ("in the loop") so that future P-frames and B-frames don't carry them forward.
The effect of applying the in-loop filter is that the edges of the macro-blocks in the output video frames are less noticeable. At the same time the image can become softer in appearance.
Although the in-loop filter can lead to reduced image detail in some frames, the overall video quality will benefit noticeably. The biggest disadvantage to using in-loop filtering is the additional decoding performance cost.
