请教一下要用X264获得和通常rmvb动画相似的画质怎么设置比较好？

感觉REF没有QP好用的说，REF有什么特别之处么？

ref和qp没有可比性吧...- -b

压什么压啊

曾经我也是小白

压了肯定损失画面质量啊

压不损耗系统资源不花时间吗？？？

一集24分钟的动画大小在150M下的坚决不能要

囧那要看什么片了

我就经常把XviD压制成X264（100MB那种）节省空间

看起来感觉还不错，质量稳超我过去压的那些片子，x264果然够变态，才309k，效果稳超600k的RMVB~~,而且才52.3M,我看音频都不用压缩了，到时候用MKV封下就行了~

subme我开的7，估计这个对动态的应该有些帮助吧~

SSIM是利用一种"视觉感受"的判断原理.这是一个华人想出来的点子(http://www.cns.nyu.edu/~zwang/)

在avs里也有介绍(avisynth_Docs/english/externalfilters/ssim.htm)
