Decomb3.91的使用方式不对.
参数应该是Decimate(Cycle=5)(默认Mode=2)
因为mode2是新加的功能, 就是特别处理NTSC的动画的.

哦,再看了一下decomb391的说明
mode (0-1, default 2) determines how Decimate() deals with the extra frame in the cycle.
If mode=0, Decimate discards the frame in the cycle determined to be most similar to its predecessor.
If mode=1, instead of discarding the most similar frame, Decimate() will either replace it with a frame interpolated between the current frame (usually a duplicate of the preceding frame) and the following frame, or it will pass the frame through as is. The choice between these two depends on the threshold parameter setting and on how different the frame is from its preceding frame (see below). Decimate(mode=1) is useful for hybrid clips where you do not want to reduce the frame rate but want to ameliorate the effect of duplicate frames that are emitted by Telecide() (frames that are normally removed with mode=0).
If mode=2, Decimate() deletes a frame from the longest run of duplicates. This mode is the most reliable with anime and other material where the motion may occur only in every second, third, or fourth (etc.) frames. If you use mode=0 on such clips, there is a danger that incorrect decimation may occur, causing jerkiness. Clips such as those described usually derive from 8fps or 12fps animation, as well as normal 24fps animation where slow motion results in repeated duplicates. Mode=2 is able to delete the correct duplicates in all these cases. Note that for the most reliable IVTC of 3:2 pulldown material, you should use pattern guidance together with this mode of decimation.
mode2是专门针对静态画面较多的动画的。1秒只有几个变化的帧的动画,就用mode2比较好。
要注意最后一句:Note that for the most reliable IVTC of 3:2 pulldown material, you should use pattern guidance together with this mode of decimation.这样的话,如果是知道片源是NTSC 3:2 pulldown的,就不但这里要用mode=2,而且在Telecide里一定要用上guide=1,才能保证ITVC。
怪不得对于vandread op这个动态非常多的动画,spdstar说不要用mode=2,要用mode=0来压了,终于明白大半,呵呵。
谢谢指导谢谢指导

那个可不一定, OP的动态场景固然很多, 但最后的几秒一般都是一个渐进的静态场景,
估计都是用8或12Frame的Duplicate出来了, 所以还是用的好.

注意大部分可进行IVTC的3:2 Pulldown片源, 你都应该同时使用Guide=1, mode=2
呵呵, 我最近中意的字体是"方正水柱简体", 很不错啊.
用记事本打开ssa, 然后另存为时, 编码从ANSI改成UNICODE, 你再试试看,
中文名的字体就都可以用了.
呵呵
