| //**Definition**: This setting controls one of the codec's' most important features: the Inloop Deblocking filter. In contrast to MPEG-4 ASP (DivX, Xvid, etc.) the Inloop Deblocking is a mandatory feature of the H.264 standard. So the encoder, The GH2 in this case, can rely on the decoder to perform a proper deblocking. Furthermore all P and B Frames in H.264 streams refer to the deblocked frames instead of the unprocessed ones, which improves the compressibility.// | //**Definition**: This setting controls one of the codec's' most important features: the Inloop Deblocking filter.
