JPG的话看不出来什么吧……上bmp

你们口口声声说学AVS,,为什么我google搜遍了也不知道这个手动编AVS压片到底是怎么回事....
编好AVS文件后用什么载入来压制啊...疯了
还有这段话
--crf 26 --ref 5 --mixed-refs --no-fast-pskip --bframes 3 --b-pyramid --b-rdo --bime --weightb --subme 7 --trellis 2 --analyse all --8x8dct --me esa --threads 2 --thread-input --cqmfile "D:\megui\profiles\video\mp4_guy's_AVC_Low_Bitrate_matrix_V2.cfg" --progress --no-dct-decimate --no-psnr
怎么载入到megui里也没人肯教一个...
jumbo@2006-11-04 12:57
生成avs文件,直接拖入megui里面
kzhou@2006-11-04 13:12
偶已经试过的
--crf 26 --ref 5 --mixed-refs --no-fast-pskip --bframes 3 --b-pyramid --b-rdo --bime --weightb --subme 7 --trellis 2 --analyse all --8x8dct --me esa --threads 2 --thread-input --cqmfile "D:\megui\profiles\video\mp4_guy's_AVC_Low_Bitrate_matrix_V2.cfg" --progress --no-dct-decimate --no-psnr
存成avs导入,
弹出错误说
Avisynth script error:
I don;t know what "crf " means
(D:\MEGUI\aaa.avs line 1)
h2o2shadow@2006-11-04 13:13
因为那个根本就不是AVS...
zhouwei_e@2006-11-04 13:23
汗,压制参数啊,楼主怎么会看成是AVS的.....

有些东西你还是要自己调的,我这个你的配置压估计很吃力的
kzhou@2006-11-04 13:45
大谢楼上,,T T
我这就试试看
下面是用默认压的,,2pass效果总比rmvb好...1pass就..
看墙上的字区别比较明显
源是码率3000kbps的MPEG-1
下面这个是用MEGUI预设的AE-Goodquality压的,码率改成了950
下面这个是950k的rmvb
下面这个是用MEGUI预设的HQ-Slow压的,码率改成了650
下面这个是650k的rmvb
最后Const Quantizer=30的1pass,,650k
追加一张用zhouwei_e大大的设置压的,,--crf 26,,出来后视频是800k
清晰度稍微比2pass950k的模糊一点,不过画面比2pass950k和2pass650k要柔和(650k的明显粗糙不少),估计同码率要胜过默认的2pass,就是压起来慢了点,研究参数头大中....
h2o2shadow@2006-11-04 14:12
AE-Goodquality 950kbps
加上 limited sharpen 试试看?
jumbo@2006-11-04 16:03
这个Low_Bitrate_matrix据说是在极低码率(<300k)下用的

kzhou@2006-11-04 16:26
那么偶把cqm改成默认的none?
另外偶看到有这个关于deblock的说法
Fire up MeGUI-x264 and you will find the profiles in the "Video Profiles" drop down list. Before starting encoding set the bitrate or quantizer (manually or thru the calculator) and adjust the inloop filter accordingly to your needs/taste: keep it 1;1 or higher for anime/toons (max 3;3) and not higher than x264 defaults (0;0) for movies.
是指压anime的话 filter调成1,1比较好么?
jumbo@2006-11-04 20:46
deblocking用1:1也行吧,不过我压dvdrip都是用-1:-1的,防止画面偏柔

多谢各位帮忙,摸索几天后终于明白avs是怎么回事了:
先编avs,用来读入音频视频源,设置切边,分辨率,
还有调用各种滤镜(这个没弄清楚,请问有哪些滤镜是常用到的,用来做什么?偶再自己去查查看。。。比如limited sharpen 也是一种滤镜么?)
编好后读进megui里面,设好264参数压制。
以上过程大家大概觉得理所当然都没怎么提,而像我这种门外汉刚来实在摸不着头脑,走了不少弯路。。。orz
要是我还是弄错了请大家指正。。m(_ _)m
另外像op和ed部分帧率是29.97,正片是23.97这种mkv的重新压缩,
以及120fps的avi重新压缩,相关的文章发现自己越看越胡涂了(手头没有试验对象。。orz)
提两个问题:
1。按普通对24fps视频的压法去压这两种视频是否都会有问题?
2。如何解决?对普通的
DirectShowSource("C:\negi.mkv",fps=23.9750084511905,audio=false)
要如何修改?。。。m(_ _)m

Low_Bitrate_matrix<---都已经更新到V4了
--subme 7--me esa <---囧一下,达到RMVB效果需要这么整么....

人家机器牛。。。我调了一些参数现在压一集动画大概2小时左右(--subme 6--me umh,顺便问ref8比起5来效果不知道明显不。。。)
Low_Bitrate_matrix的v4,不hd的求贴一个上来..m(_ _)m
