这个...晕@..除了最后一条不就是先前那个PSNR最高设置...
没记错的话"patternAdaptivity = 2"这句在低码率下对视觉效果有很大影响...
P.S.前一阵那个解决采样率问题的旧版racp的"更新DLL"偶用了后发现还是22k的哈...这次又是新的吗...
This option takes chrominance (or color) into
account when choosing the best encoding modes.
Fix: encodeAllFrames and rcBestPSNRMode would always
be ON if included in audience, if if set to 'false'
Fix: long standing bug where if Constant Quality less than 20-30
and EHQ greater than 70, bitstream could not be decoded. Thanks
to Satsuki for discovering the problem.

With option chromaModeDecision, for a chroma intensive anime test clip I measured +0.25 dB improvement in Overall PSNR for UV, and 0.04 dB for YUV. No change in Luma PSNR.
不只是bugfix, 还增加了chromaModeDecision, 提升了UV的质量..........

chromaModeDecision这个我已经做了进去RPG 1.32，我是直译为“决定色度模式”，不知S版有更合的译名吗？还有能发表一下对另外两个选项的看法吗？
skywalker@2004-10-28 04:00
这几个选项我都没试过...........照说明来看..........
chromaModeDecision就是提高在色度的编码质量, 也就是说大概以前的EHQ没有怎么处理色度信息, 可能是为了提高编码速度吧................
我建议这个可以翻译为"高质量色度处理"之类的...........
谁有时间还是具体拿几个动画试试看吧...........
karl的测试都不是用的动画, 他也不知道在动画上效果是不是会提高......
按照Siber的说法, 他的测试显示, 在动画上, 老的RC比

超级感谢 skywalker 兄的保贵意见!chromaModeDecision以后就译为"高质量色度处理"，在完成1.32前我都没时间测试，今早做了个逐帧比较，开启后色泽是好一点，以后决定RPG默认是开启它。马后炮^_^
