1-pass和2-pass如果都选Mod. HQ或Moderate的话, 就等于2个pass都用MPEG.
只有1-pass用H.263, 2-pass的Mod.HQ和Moderate才有效.
Mod的含义是2-pas时根据1-pass的量化结果, 在H.263和MPEG之间切换.
(类似于DivX3.11a的SBC)
Mod是Quad在1~3时用MPEG, 3以上用H.263
而Mod.HQ则相反, 是一个新的尝试.

首先谢谢XviD的制作者为大家带来完全免费而效果非常不错的Codec,然后谢谢在射手网写教程的朋友和花园的csr2000兄,下文就是参考各位前辈们写的东西,呵呵引用1-pass和2-pass如果都选Mod. HQ或Moderate的话, 就等于2个pass都用MPEG.

六、现在回到VD,在Video菜单那里选回Full comperion mode和点上面的Compression,然后在出来的窗口选XviD,然后点Configure再选2pass-2nd pass Ext,如图引用StatsReader v1.5 HowTo:
- do a "usual" first pass
- open the resulting stats file with statsreader
- enter your desired size
- enter your credits ranges. Currently works only with fixed quant. credits, you have to use them in first pass as well!
- verify your settings, just to be sure ;)
- hit "Save..", choose a filename different from the original file
- when StatsReader is finished, it spits out some information like scaled size reached (due to rounding errors usually in a 100kb range of desired size) etc.
Now in XviD, select "2pass - 2nd pass external". The easiest way to do it properly would be: set "old", "regular" curve compression high/low to 0 and disable altCC. OR set altCC to automatic min. relative quality, set strength to 0. OR set min. realtive quality to manually and set it to 100. (Quite a lot of choices ;) ). Below the first pass stats file in the GUI you can now choose a second statsfile. Use the new generated statsfile in this place.
That's it, if you tried it you'll notice that it's not much of a difference to usual 2pass encoding, you simply "disable" curve compression within the codec and feed it the new stats file.

既然要傻瓜式的,就不一定要用XVID了
