Well... I generally hold the same opinion as you, and my vote is for lumi masking in both passes too
. Still, I'll do another test encode (to make myself absolutely believe in this) with the 08082002-1 build. Two rips of the same movie, heading for 640000 kb video size with the exact same parameters (without AltCC in order not to put the blame on it later
), except that one will be with lumi masking in both passes, and the other with no lumi masking at all.
Then I'll compare the results in terms of both visual quality/artifacts especially in dark scenes and compressibility/average quants. If I notice any problems after watching and frame-by-frame analyzing both encodes, I'll let you know, together with the screenshots for comparison.
But I guess it will take some time, 'cause currently I've already been doing some other encodes.
with my best regards to all,
