When i read the release notes, i notice the following: The number of levels available for encoding complexity was reduced from 5 (very-high, high, normal, fast, vary-fast) to 3 (high, medium and low) for several reasons: Only some of the 5 options were triggering unique behavior in most of the codecs that supported the encodingComplexity property. Thus, users might change the setting from fast to very-fast with no change in behavior. This is not a very good user experience. The EHQ technology added to RealVideo 9 was separated out into a new codec - itself with 3 ranges. The new codec is yet complete but RealVideo 9 is still available in this build. RealVideo 9 no longer includes the EHQ technology so there is no method in Milestone 8 to exercise EHQ. Please use Milestone 7 if you wish to encode with RealVideo EHQ. Does this mean we can't use ehq with M8 anymore? I also see a "9.2M8 RV9 Patch", it looks like the new 2-pass patch, is it the same as the one Karl put up in his "RV9 2-pass VBR improvements " thread?
