Force LoopFilter
The Force LoopFilter registry value specifies whether the codec should use the in-loop deblocking filter during encoding.

When the codec uses the in-loop deblocking filter, the edges of the macroblocks in the output video frames will not be as noticeable. However, the filter makes the image softer in appearance.

Data Type

REG_DWORD

Valid Values

This value can be set to 0 or 1. 0 indicates that the codec will not use the loop filter; 1 indicates that it will.
