Still can not do good medium-to-high bitrate (~1Mbit) encode - too blurry. Seems that deblocking must be disabled for such a bitrates...
Will check it...
SSIM for deblock adapt (beta 2)

source HPII 640*272
~1700 Kbps with XviD q2 default setting

Code:
bitrate	          600	  800	 1000	
deblock off	75.26	79.59	83.12
adapt -6	75.46	79.68	83.11
adapt -4	75.46	79.68	83.11
adapt -2	75.47*	79.68	83.11
adapt 0	        75.84	79.76*	83.11
adapt 2	        76.45	80.21	83.24*
adapt 4	        76.96	80.75	83.57
adapt 6	        76.71	80.88	83.92

* Deblock activation treshold
Deblock for H264 is "adaptative". For low bitrate (high quant) treshold activation is low and for high bitrate (low quant) treshold activation is high. I think that for very high bitrate deblock is in practice off ...
