AviSynth入门与应用指南
第一讲 Avid操作入门
非线性编辑的优点
非线性编辑只要上传一次就可以多次的编辑, 信号质量始终不会变低,所以节省了设备、人 力,提高了效率。非线性编辑需要专用的编辑 软件、硬件,在现在绝大多数的电视电影制作 机构都采用了非线性编辑系统。
二. 影视制作的基本流程
(1)前期准备 当创意部门完全确认方案并获准进入实际制作阶 段后,创意部门会将创意的文案、画面说明以及 故事版全部呈递给制作部门。制作部门将在创意 部门的帮助下,区分拍摄部分与数字制作部分, 并对镜头脚本、导演阐述、灯光影调、音乐样本、 布景方案、演员造型、道具及服装等一切有关拍 摄的所有细节进行全方位的准备工作。 (2)拍摄 依照前期准备的拍摄计划,由摄制组进行拍摄工 作。根据一般的作业习惯,为了提高工作效率, 往往会将机位、景深相似的镜头一起拍摄,而并 非按照镜头脚本的顺序进行。并且,为了保证拍 摄的镜头足够用于剪辑,每个镜头都会尽量拍摄 不止一遍。
(3)数字制作 有些创意内容是实际拍摄工作无法实现的,比如卡 通角色的融合等。数字制作组会根据创意部门提供 的资料进行这些内容的制作工作,为后期制作提供 足够的素材。 (4)后期制作 初剪:初剪,也叫粗剪。一般会按照最初的故事版 中的顺序将拍摄素材与数字素材一并顺接起来,进 行简单的视觉修正,形成一个没有视觉特效、没有 配音和配乐的版本。 (5)特效合成 依照脚本的描述,将需要的特效部分合成到影片中。

一、 数字视频的基本知识
(1)传统电视系统的组成
电视是目前世界上利用最广泛的传播媒体, 是传送声音和活动图像的传播方式,是应 用电子技术对静止或活动的自然景物影像 进行转换、记录、传送和重现的技术工程。 电视系统主要由信号获取、记录、传送和 接收重现四大部分组成,如图 所示。

这座桥梁不是简单 的独 木桥、而是有栏杆、有台阶(比喻其提供的大量虑镜)。
因此比较灵活!如对 于压制 real 格式来说,源媒体文件是 vob、d2v(DVD 处理过程中的中间文件)、 ac3、mp3、avi、DAT/mpge 等,而应用程序是各种 real 压缩软件如 Helix real producer、BatchRealProducer144 和 EasyRealProducer14,它们都支持 avs 的导入。
当然 avs 并不只是用于 real 压缩。
它是媒体文件和压缩软件之间的 “桥梁”,只要 avs 支持你所需要处理的媒体文件,压缩软件也支持导入 avs 文件,你 都可以通过 avs 对视频进行处理,然后让压缩软件输出你所需要的格式的文 件。

[转载]AVS教程:AviSynth学习手册【第八节Decomb实战篇】实战Decomb做IVTC/Deinterlace处理在上一节中,我们讲解了Decomb中三个场处理函数的使用方法与参数。
在本节中,我们将针对具体例子来讲解这三个函数的组合应用。
首先我们来看纯Interlace片源的Deinterlace处理:范例脚本:LoadPlugin("decomb.dll")#加载Decomb滤镜AVISource("nonfilm.avi")#导入片源FieldDeinterlace()#使用FieldDeinterlace进行Deinterlace处理,全部参数均为默认。
然后,我们来看看针对3:2 pulldown片源只反交错,不删除重复帧的处理:LoadPlugin("decomb.dll")AVISource("film.avi")Telecide(order=1)#使用Telecide函数进行场匹配反交错接下来,我们来看看IVTC(在场匹配反交错的同时删除重复帧)的做法:LoadPlugin("decomb.dll")AVISource("film.avi")Telecide(order=1)Decimate(cycle=5)#用Decimate每五帧删一帧禁用Postprocessing:LoadPlugin("decomb.dll")AVISource("mixed.avi")Telecide(order=1,post=0)#post=0为禁用PostprocessingDecimate(cycle=5)对3:2 pulldown含量很大的影片进行IVTC:LoadPlugin("decomb.dll")AVISource("mixed.avi")Telecide(order=1,guide=1)#使用guide=1对3:2 pulldown的片源处理进行优化Decimate(cycle=5)处理hybird片源:LoadPlugin("decomb.dll")AVISource("hybrid.avi")Telecide(order=1,guide=1)Decimate(mode=3,threshold=2.0)#使用Decimate的mode参数对hybird影片的处理进行优化,具体配制方法请见上一节。
[转载]AVS教程:AviSynth学习手册【第五节IVTCDeinterlace应对策略】
[转载]AVS教程:AviSynth学习手册【第五节IVTCDeinterlace应对策略】接下来的数节中,我们将讲解IVTC/Deinterlace。
IVTC/Deinterlace无论如何都是一个值得大书特书的过程,DVDRip 一半的质量都是取决于IVTC/Deinterlace的好坏。
首先,我们先了解一些概念。
24p:本章经常会遇到这个概念,意思就是,24fps无交错的胶片,经过胶卷过带,最终形成的30fps、每五张中有两张交错的片源。
30i:意思是,30fps、张张都Interlace(交错)的片源。
场匹配反交错:这个动作一般对象指得是24p的影片,通过对(前)中后三帧进行场匹配(具体原理下文会讲),还原原本没有交错的画面。
注意,是还原!这样还原出来的帧和原来没有交错的帧理论上应该是一模一样的。
场匹配反交错是在帧与帧之间进行的。
Deinterlace:反交错,通过一定手段,让原本交错的帧显得不再交错。
注意,是“显得不再交错”而不是“还原”,经过Deinterlace 的画面与原本的画面是有很大差别的。
Deinterlace只在本帧内进行,是对单幅画面的处理。
注意,Deinterlace一定要和场匹配反交错这个概念区分开!否则读下文的时候会非常糊涂。
接下来,我们先来复习一下各种类型片源的处理方案。
24p(也叫Film、3:2 pulldown型)有些影片,讯源是24fps,拍摄的时候是用胶片以24fps拍摄的,每一张都没有交错,例如大部分的电影。
为了要能在NTSC 的电视上播放,电影胶卷过带(telecine)的时候必须转成30fps(即前面说过的3:2 pulldown)。
这种影片,其原始画面其实是 24fps无交错的,可以作IVTC,经过场匹配反交错、删除多余的画面,还原回原本的24fps。
大部分的电影,无庸置疑,其讯源一定是 24fps无交错,可以作 IVTC。
电影转成PAL(25fps)的时候,用的是2:2 pulldown,画面还是无交错的,只是加快播放速度,变成每秒播放 25 张。

VCB-Studio教程07AviSynth基础与入门
VCB-Studio教程07: AviSynth基础与入门0. 前言这篇教程需要教程6:VS基础与入门作为前置尽管avs早于vs存在了十几年,上手写一个hello world级别的脚本也比vs容易,但是avs混乱的参数传递机制,使得想深入学习avs的使用,比vs其实来的困难。
本教程假定你通过vs教程,已经对变量、参数传递等有了最基本的认识,这样,当我们讨论avs特有的一些机制的时候,不至于从零开始。
AviSynth主页和文档:AviSynth+主页和文档:在线词典:avs目前最新版是avs 2.6.0,只有32bit;avs+是avs的一个改良mod,优势在于,有官方64bit版本。
尽管以vcb-s对于avs+的使用,全局64bit化是可行的,但是因为懒,所以直到转vs之前,vcb-s一直使用32bit 版本的avs。
如果你希望使用64bit的avs,建议使用avs+。
有vs的存在,avs的意义不是很大,至少作为定位高质量、复杂处理的压制,vs优秀的内存管理机制、原生的多线程优化,和各种新科技滤镜,让它对比avs已然优势明显。
但是vcb-s系列教程依旧讲述avs,因为很多以前的教程和脚本是基于avs的,我们需要保证大家能理解并继承上个时代的智慧结晶。
1. 简单的avs脚本以下是一个简单的脚本,以YUV420P16的格式读入一个mkv,并转为RGB32显示:SetMemoryMax(1000)a = ""LWLibavVideoSource(a,format="yuv420p16",stacked=true)dither_convert_yuv_to_rgb(chromak="lanczos",taps=4,noring=true,lsb_in=true)avs原生不支持多线程,但是支持设置最大使用内存。
这里我们用setMemoryMax()来设置最大使用1000MB。
基础工具的安装和调试-VCB-Studio教程专栏
VCB-Studio教程03:基础工具的安装和调试本教程讲述如何安装并调试avisynth+, avspmod, VapourSynth, VapourSynth Editor, MeGUI, mkvtoolnix和MediaInfo. 调试的方法中顺道介绍常见的源-成品对比手段。
1. avisynth+ 和avspmod 的安装avisynth是一直以来滤镜处理的传统工具,后来分裂成avisynth 2.6.0(简称avs 2.6) 和avisynth+(简称avs+),两者大同小异。
本系列教程如无例外,均以avs+ 32bit为准。
avs+只允许标准安装,不像avs 2.6允许标准安装和绿色安装,容易造成版本和滤镜目录的混乱。
SVP(Smooth Video Project)依赖avs运行。
所以如果你需要使用svp,不建议你重新安装avs+。
安装avisynth+之前,先去控制面板-程序,找到之前所有的avs版本,卸载。
如果卸载完了有弹窗问你是否要保留滤镜目录,选否。
然后安装avisynth plus的本体:https:///AviSynth/AviSynthPlus/releases/download/Rel-r1576/AviSynthPlus-r1576.ex eLanguage选English。
安装目录,千万记好你装到哪里。
随后的安装选项,你可以根据你的需要选择32bit(x86)还是64bit(x64),一般情况下推荐只安装稳妥的32bit,毕竟avisynth官方没有64bit版本,一些组合滤镜也很难把所有插件找齐64bit版本:32bit的avs,一般被32bit的自行环境启动,比如说32bit的播放器,32bit的x264。
如果要想让64bit的编码器读取32bit的avs,则要借助avs4x264.exe这样的pipe工具。
同理,64bit的avs只能被64bit的环境自动启动。

【应用】AviSynth(AVS)滤镜参考手册
【应用】AviSynth(AVS)滤镜参考手册【应用】AviSynth(AVS)滤镜参考手册一、加载插件1、LoadPlugin() 加载插件如:LoadPlugin("VSFilter.dll") 加载字幕插件LoadPlugin("mpeg2dec3.dll") 加载DVD的mpeg2编码器插件LoadPlugin("mpasource.dll") 加载mp3插件请下载以上提到的滤镜!并解压制到plugin目录里(当然目录可以自己选定),如果avs 文件和滤镜不再同一个目录下,记得要把加载滤镜的路径名写全了。
有些滤镜或者脚本是avisynth核心的滤镜或脚本,也就是avisynth本身提供的功能,这些就不需要加载,其它的都需要加载。
你也可以用SetWorkingDir设定插件文件的工作路径。
2、SetWorkingDir() 指定插件路径SetWorkingDir("d:\GORDIA~1\") 设定AVS 脚本调用dll 插件文件的工作路径这样设置好后,就可以在下面直接写调用语句了,不需要再一个一个的写滤镜的路径了,但前提是.dll的滤镜文件已经复制到设置的文件夹下了。
例:SetWorkingDir("D:\AviSynth 2.5\plugins\") 设置滤镜的目录LoadPlugin("VSFilter.dll") 调用字幕滤镜插件二、源媒体读取1、DirectShowSource() 万能调用如:DirectShowSource("e:\vob\ss.VOB")DirectShowSource()在高版本avisnyth中显得更万能些,常用的媒体格式,如avi、mpge1/dat、mpge2/vob/bin都可以加载,另外可以不用分离视频和音频,而直接压缩!想要直接压制vob请使用高版本的avisynth,如目前的2.54 。

AVI视频压缩软件《WisMencoder》使用方法
AVI视频压缩软件《WisMencoder》使用方法WisMencoder是目前最快的AVI压缩软件.论坛有下载最新版1.32. 能够把电脑上的所有视频格式,包括avi,mpg,rmvb,wmv,mp4,mov,dat等格式以最快的速度和最高的质量转换为AVI格式。
速度和质量都高于同类软件。
首先看一下软件的界面即时帮助鼠标在某个项上停留0.5秒左右的时间就可以显示关于这个项目的解释。
(不是所有项目都有这个帮助,但是对于重要项目都有)添加任务和队列压缩要添加文件又想采用不同的配置参数时,就可以按添加新任务,先把现有的这批(或者一个)文件的配置任务保存起来,列表请空,您可以继续添加不同的文件和参数,如果还需要不同的参数,还可以继续点击“添加新任务”。
直到都配置好后,点击“开始压缩”就会依据您所设定的,对不同的文件实行不同的配置参数。
CPU的选择Wismencoder是基于mencoder的核心,mencoder针对每种cpu做了优化,事实上,选择哪种CPU都能进行压缩。
但是对于某些文件,可能会导致压缩不成功。
如果看不到你所要的CPU,则如果是奔腾系列的,就选择P3或者P4都可以。
如果是AMD的,则选择k7即可。
音频的设置单声道通常选编码率24 采样率16000或22050均可.立体声试过128 44100的码率(VBR)此点在压制MV时特别有用.小P用TCPMP播放很流畅.更高的码率我还没试过.应该没问题.另外只能选MP3.其它选项小P不支持。
视频的设置根据源文件的不同编码率在240~300均可.帧率:动作片18~20 生活片12~13.推荐动态XIVD编码,添五即可。
关于字幕黑边问题左右黑边和上下黑边要填的都是总宽度,也就是一边黑边宽度的2倍,这个要注意。
黑边主要是为了放置字幕,如果不需要字幕则这个功能也就没什么用了。
还要注意的是!要使黑边功能生效,“视频”选项卡里的“分辨率”那里,长、宽都应是确定的数,如有空白或者选择了“自动适应高度”、“自动适应宽度”,则黑边功能失效。
AviSynth帮助文件中文版
例如:
FadeOut(15, ReduceBy2(Version))
而且可以理解为函数作用于表达式。面向对象设计的符号有一个缺点就是只能使用带有一个视频剪辑参数的滤镜,而不能用于带有多个参数的滤镜。
不管语法看起来有多复杂,所有的AviSynth函数都可以生成输出帧数和帧速率的定义号。AviSynth在读完脚本之后就知道输出会有多长,帧速率是多少,以及所有输入的剪辑顺序。这些都在打开脚本的时候被计算出来。只有实际的过滤过程是按照需要在运行时进行的。
UnalignedSplice(AVISource(“d:capture.00.avi”),AVISource(“d:capture.01.avi”),AVISource(“d:capture.02.avi”))
StackVertical和UnalignedSplice都可以带两个或者最多六个参数。你可以用+运算符作为UnalignedSplice的简捷方式。例如,上面的脚本和下面的脚本完成同样的功能:
a = 10 – 5 – 5 结果为 10- (5 – 5 ) = 10 而不是 (10 – 5 ) – 5 = 0 !
这个错误已经被改正过来。从2.53版开始,连乘法和除法都是从左到右解析(而不是从右到左)。
对于string类型:
+ 加
>= 大于等于(大小写敏感)
<= 小于等于(大小写敏感)
AudioDub(AVISource(”d:capture.00.avi”)+AVISource(”d:capture.01.avi”)+AVISource(”d:capture.02.avi”), WAVSource(”d:audio.wav”))(筝儿:上面的例子应该写成一行)
AviSynth核心滤镜中文文档
AviSynth核心滤镜中文文档
多媒体文件滤镜
这些滤镜能被用来读/写多媒体文件. 通常他们产生用于处理的片源.
颜色转换和校准滤镜
这些滤镜能用来改变剪辑的颜色格式或校准颜色.
覆盖和遮罩滤镜
这些滤镜能被用来用遮罩层叠视频或者创建遮罩.
几何变形滤镜
这些滤镜能被用来改变图像的尺寸, 加工剪辑的边缘或其它几何变形.
像素修复滤镜
这些滤镜能被用来修复剪辑的图像细节(像素).如去噪, 锐化.
时间轴编辑滤镜
这些滤镜能被用来在时间上排列帧(视频切割, 合并和其他操作).
交错滤镜
以下滤镜用于创建和处理基于场格式的视频素材(由于基于帧格式的素材被拆成了场格式而产生的).虽然AviSynth能处理逐行和交错视频,但主要问题是它经常不能分辨从源滤镜获得视频剪辑的形式.这就是场标志(Field-based Flag)存在并被用于处理交错视频素材的原因.
音频处理滤镜
以下滤镜用于处理音频。
从一段剪辑中获取的音频样本将会被自动转换成某些滤镜需要的特殊形式。
这意味着如果某个滤镜不支持输入音频样本的格式,它将自动转换成某种被支持的格式。
每个滤镜内置的支持格式在下表中的样本格式栏中给出。
如需指定某种特殊的格式,可以使用ConvertAudio函数强制转换.
如果某样本格式是浮点型,当AviSynth需要输出数据时,它将被自动转换成16位整形,因为浮点型不是AVI数据的合法输出.
条件滤镜和其它元滤镜
元滤镜可以用来控制其他滤镜的执行。
条件滤镜的基本特征是它们只对每一帧而不是对整段视频起作用。
这允许您能处理使用一般AviSynth脚本很难或不可能完成的复杂视频处理任务.
调试滤镜。

AVID简易使用说明
AVID简易使用说明B302、B303、B305、B306进入AVID剪辑软体的程式后,首先必须要先设定一个新的Project,设定Project的用意在于新增或选择使用者的专案设定,可以选择所要使用的专案性质为Private(私人)或Shared (共用),但是若非在私人电脑上使用AVID程式,例如使用学校的电脑,选择私人或共用便没有差别,其他人还是可以使用你的专案进行剪辑。
新增专案时,系统会要你指定影像规格为NTSC或PAL,有关于NTSC与PAL之间的差别,请查阅相关资料。
开启所选的Project后,便进入AVID的主视窗,在这里可以看到你的个人资料库视窗、监看器视窗(Composer)、以及时间轴(Timeline)。
个人资料库-Bin:作用在于存放所有剪辑所用的资料和完成的影像,可以说是影像的资料夹,在开始剪接之前,必须要先设一个新的Bin,并给予适当名称,以方便做资料整理。
个人资料库-Setting:在开始剪辑之前,必须对此专案的剪辑方式做喜好设定,而在诸多选项中,有少数项目对剪辑的过程有较大的影响。
1. Audio Project:确定此选项中的Sample Rate(声音取样率)为48Khz;Sync Model为DV;Import Source为OHCI(视情况也有可能选择CD或Mic)2. Bin:在此可以设定档案自动储存的时间。
3. Deck Configuration:用来侦测剪辑时用来撷取影像的器材(过带机或DV摄影机)是否与电脑连结成功,若未连结,便须将过带机或DV摄影机的电源重新启动,并按下选单中的Auto-Configuration来重新连结。
4. Deck Preference:在此选单中上方的撷取方式选择Drop Frame(丢格),让电脑自行将影像的撷取形式套用为NTSC系统所用的一秒30格画面。
5. General:可以自行设定影片起点的时码为何,预设值为00:00:30:00。
Avigilon Control Center 7 软件:不寻常运动与活动检测说明书
AVIGILON CONTROL CENTER ™7 SOFTWAREUNUSUAL MOTION & ACTIVITY DETECTIONAdvanced AI technology that highlights the unanticipated byautomatically flagging unusual motion and activity. This edge-based intelligence technology distinguishes between typical and atypical events by continuously learning from observation of scenes over time. Unusual Motion Detection (UMD) detects atypical movement, while Unusual Activity Detection (UAD) is object-aware and detects the anomalous speed and location of people and vehicles.UMD is available on H5SL, H5M, H4SL, H4A and H4 Mini Dome cameras. UAD is available on our H5A camera line.FACIAL RECOGNITIONAI-powered facial recognition technology that helps organizations accelerate response times by identifying people of interest. People of interest are identified based on one or more secure watch lists managed by authorized users at the organization. Populate watch lists easily by either uploading images or finding a face from recorded video. A set of configurable controls are available to support the management of the various watch lists.Avigilon cameras licensed for facial recognition will search the configured face watch lists for potential matches. If a match is found, operators can be notified either using the FoA interface or through ACC alarms using armed panels or the alarm view. ACC will display the video image that triggered the alarm along with the reference image from the watch list, enabling operators to verify the match and act quickly.Avigilon Control Center (ACC) 7, our latest and most advanced version of ACC ™video management software, is designed to revolutionize how operators interact with and gain situational awareness from their video security systems.FOCUS OF ATTENTION (FOA) INTERFACEA cutting-edge user interface for live video monitoring that leverages AI and video analytics technologies to determine what information is important and should be presented to security operators.AVIGILON APPEARANCE SEARCH ™ TECHNOLOGYSophisticated AI-powered video search engine that sorts through hours of video with ease to help quickly locate a specific person or vehicle of interest across an entire site or multiple sites running the same version of ACC software. Search for a person or vehicle of interest by entering a physical description, or by finding an example in recorded video.CLOUD-CONNECTED ACCAvigilon Cloud Services (ACS) connects existing ACC sites to the cloud for easy and secure remote access to video from a standard web browser. Operators can leverage centralized System Health Monitoring to assess the operational state of cameras and servers from a central location. Benefit from future enhancements of ACS by updating to the latest versions of ACC software.CYBERSECURITY & PRIVACY PROTECTIONACC security measures include strong password enforcement, connection authentication and data encryption, as well as strict user permissions to access search functionality that uses personally-identifiable information.Blurred Export helps support compliance with new data protection and privacy requirements of GDPR by allowing you to export Appearance Search results in ACC software while blurring the background of the camera view to feature only the person of interest in the video.For U.S. government agencies and enterprises that require FIPS-compliant cryptography, ACC software offers an option to use Microsoft Windows’ FIPS 140-2 certified cryptographic libraries to comply with IT policies.LICENSE PLATE RECOGNITION ANALYTICSAutomatically reads license plate information from vehicles, linking it to both live and recorded video. Create and import multiple vehicle license plate watch lists for instant alarm notification when a license plate match is detected, or search and quickly find specific captured license plate video for verification and investigation.COVID-19 RESPONSE TECHNOLOGYOperate safely and comply with local health and safety guidelines with the help of powerful video analytics – natively available to operators on ACC 7 software with no additional licenses required:Occupancy Counting: Automate the manual counting of peopleentering and exiting a facility or area. Use real-time dashboards on mobile tablets to instruct customers on when to enter or queue.Social Distancing: Run reports in ACS to proactively identify where and when social distancing guidelines are not being followed for corrective action.No Face Mask Detection: Automate the detection of people not wearing face masks, complete with alarms to flag violations in real-time. Run reports in ACS to identify where corrective action is required.FEDERAL GOVERNMENT COMPLIANCE WITH FIPS 140-2 CERTIFIED ENCRYPTIONWithin ACC, there is now the ability to optionally turn on licensed FIPS cryptography on Avigilon cameras. ACC will inventory the number of FIPS camera licenses being used and determine whether customers have the required number of licenses within a facility.AVIGILON H4 THERMAL ELEVATED TEMPERATURE DETECTION (ETD)ACC is built to work seamlessly with the new Avigilon H4 Thermal ETD solution, which offers a low friction, contactless alternative to traditional screening methods.ACCESS CONTROL UNIFICATIONACC software works together with the Access Control Manager (ACM) system to receive and act on ACM ™door events, hardware input events and access grants, empowering operators to unlock access doors directly from a camera view. Identity Verification dynamically displays ACM credentials with ACC camera views. Identity Search can help find a person of interest using their ACM cardholder information.© 2020, Avigilon Corporation. All rights reserved.

【应用】AviSynth(AVS)滤镜参考手册
【应用】AviSynth(A VS)滤镜参考手册一、加载插件1、LoadPlugin() 加载插件如:LoadPlugin("VSFilter.dll") 加载字幕插件LoadPlugin("mpeg2dec3.dll") 加载DVD的mpeg2编码器插件LoadPlugin("mpasource.dll") 加载mp3插件请下载以上提到的滤镜!并解压制到plugin目录里(当然目录可以自己选定),如果avs 文件和滤镜不再同一个目录下,记得要把加载滤镜的路径名写全了。
有些滤镜或者脚本是avisynth核心的滤镜或脚本,也就是avisynth本身提供的功能,这些就不需要加载,其它的都需要加载。
你也可以用SetWorkingDir设定插件文件的工作路径。
2、SetWorkingDir() 指定插件路径SetWorkingDir("d:\GORDIA~1\") 设定AVS 脚本调用dll 插件文件的工作路径这样设置好后,就可以在下面直接写调用语句了,不需要再一个一个的写滤镜的路径了,但前提是.dll的滤镜文件已经复制到设置的文件夹下了。

这座桥梁不是简单 的独 木桥、而是有栏杆、有台阶(比喻其提供的大量虑镜)。
因此比较灵活!如对 于压制 real 格式来说,源媒体文件是 vob、d2v(DVD 处理过程中的中间文件)、 ac3、mp3、avi、DAT/mpge 等,而应用程序是各种 real 压缩软件如 Helix real producer、BatchRealProducer144 和 EasyRealProducer14,它们都支持 avs 的导入。
当然 avs 并不只是用于 real 压缩。
它是媒体文件和压缩软件之间的 “桥梁”,只要 avs 支持你所需要处理的媒体文件,压缩软件也支持导入 avs 文件,你 都可以通过 avs 对视频进行处理,然后让压缩软件输出你所需要的格式的文 件。
也许你还是不明白 AviSynth 能做什么,举些简单的例子,你需要对 一段 avi 进行处理。
你想把画面尺寸缩小,你可以用 avs;你想把画面上的杂点消除, 你可以用 avs;你想把画面处理得锐利些,你还是可以用 avs;AviSynth 是桥 梁,位 于媒体文件和压缩软件之间,压缩软件可以通过 AviSynth 调用和处理媒体文 件。
而且不仅仅是压缩软件,甚至是播放器也能调用 avs,对播放的文件进行 处理, 得要需要的播放效果。
AviSynth 首先要编写建立一个包含特定命令的文本。
注意这里的文本,简 单的说就是 windows 的写字板写出来的文件,你可以用任何一种文本编辑器打 开进行 编辑。
这一特定命令的文本称之为"脚本"(文件后缀名为 avs),这些命令指定 要运行处理的媒体文件和滤镜! AviSynth 的平台和相关滤镜更新比较快,功能不断增加,编辑 avs 脚本也更简 单。
在射手网可以下载到这个平台软件。
至于滤镜可以到得到 /warpenterprises/ 下载,至于 doom9 论坛,大家知 道有这么个乌合的巢穴就可以了![编辑]基本认识上面简单介绍了 AviSynth 的一些基本概念作为引子,在正文开始前,我想首先 交待很重要的一点:avs 脚本及其各种滤镜主要适用于大码率媒体文件的处 理,也 即我们经常接触的 DVDRIP/TVRIP avi 的制作优化。
而对于高度压缩格式的 rmvb 来说,我们利用的 avs 滤镜更应该持慎重态度(如亮虑镜、字幕虑镜、画 面调整等 少数几个)!也就是说 avs 在 rmvb 压制方面,我们需要的是利用 avs 灵活的 “中间人”的角色(看下面的例子)!而不是为了 avs 而去压制!我看到好多 朋友初步接触 rmvb 压制,就在用 avs 压制 DVDRIP-rmvb,完全套用个别论坛给出的 avs 脚本,里面全是各种滤镜,如 3D 增强、柔化、去丝等!这些滤镜如果制作 DVDRIP 的 avi 那是会获得肯定的画质效果,但是用于 rmvb 压制,仿佛就是东施效颦, 忠言逆耳!real 压制的原理和高码率的 mpge4 编码是不同的,后者有视频上层 的概念 ,因此滤镜的修饰作用可以体现。
我看 Doom9 讨论 avs 时,主要还是处理各种 大数据量影像媒体为主。
如处理自己 DV 录制的影视、电视卡录制的视频源之类 的等。
而众所周知的影响 real 媒体压缩效果就是片源效果。
VCD 片源的再怎么处理也 不可能达到 DVD 的效果,而 DVD 片源,再怎么胡乱压制也不会差到哪里。
因此 avs 直接 在 rmvb 的压制中需要适当选择,而不能盲从,特别是对于各种滤镜的选择更要 注意。
一句话 AviSynth 非常灵活,要按具体情况具体分析。
第二,需要认识 avs 的桥梁作用。
修饰之余尽可能的使用压缩软件本身的功 能。
对于 real 压缩,如 rmvb 压制中帧率的改变就可以在压缩软件中进行设 置,而不 要在 avs 中写入相关的语句。
另外各种压缩软件使用的是 real 的压缩内核,而 real 压缩一般以 YV12 的快速处理环境为主。
这也是在使用 avs 压制 rmvb 时需 要注意 的问题。
自己觉得上文对 avs 的介绍及应用范围要比下面的内容来的更重要!这是我 直到现在才撰写完毕这篇小文的良苦之处。
下面先简单的介绍些基本方法和常用滤镜,滤镜可以理解为各种处理视频的 工具。
首先安装 avisynth,并将常用虑镜插件 dll 文件拷贝到安装目录的 plugin 目录里。
[编辑]基本代码LoadPlugin(),加载插件[编辑]1.如: LoadPlugin("VSFilter.dll") 加载字幕插件 LoadPlugin("mpeg2dec3.dll") 加载 DVD 的 mpeg2 编码器插件 LoadPlugin("mpasource.dll") 加载 mp3 插件请下载以上提到的滤镜!并解压制到 plugin 目录里(当然目录可以自己选 定),如果 avs 文件和滤镜不再同一个目录下,记得要把加载滤镜的路径名写 全了。
有些 滤镜或者脚本是 avisynth 核心的滤镜或脚本,也就是 avisynth 本身提供的功 能,这些就不需要加载,其它的都需要加载。
你也可以用 SetWorkingDir 设定 插件 文件的工作路径 SetWorkingDir("d:\GORDIA~1\") # 设定 AVS 脚本调用 dll 插件文件的工作路 径[编辑]2.源媒体读取DirectShowSource("e:\vob\ss.VOB") DirectShowSource()在高版本 avisnyth 中显得更万能些,常用的媒体格式,如 avi、mpge1/dat、mpge2/vob/bin 都可以加载,另外可以不用分离视频和音频 ,而直接压缩!想要直接压制 vob 请使用高版本的 avisynth,如目前的 2.54 。
如果遇到打不开的媒体格式你大都可以试试看 DirectShowSource。
AVISource(e:\avi\1.avi,false) 这个对于 DVDRIP 压制者来说可能更常用些.false 表示禁止音频! mpeg2source("XXX.d2v") 这个用于解码 DVD 的 mpeg2 格式的视频 WAVSource("e:\vob\ss.wav") 读取 wave 音频 AC3SOUECE("e:\vob\ss.ac3") 读取 ac3 音频 MPASOURCE("e:\vob\ss.MP3") 读取 mp3 音频 注:WAVSOURCE 和 AVISOURCE 是属于核心脚本,无须读取插件,但 AC3SOURCE 和 MPASOURCE 需要读取 AC3SOURCE 和 MPASOURCE 插件。
DirectShowSource 的读 取 需要安装各种音频和视频的解码器[编辑]3.crop()、LanczosResize()裁黑边和调整大小vob 文件画面大小一般 720×480。
16:9 宽银幕的都带了很大的黑边,需要裁 减掉。
也是 avs 用于 vob 压制的关键因素之一 裁减黑边和缩放画面是 vob 文件压制中很重要的因素,一般连用。
对于本身就 无黑边的文件直接用 LanczosResize() 16:9 画面的有 2 种情况,请记住这几个数值,在 rmvb 压制中直接套用即可!DVD 变形宽银幕:640×352,608×336 电影宽银幕: 640×272 如要将电影宽银幕的画面比列调整到 640×272,avs 里可以这么写 Crop(8,90,704,300) LanczosResize(640,272) 如要将 DVD 变形宽银幕的画面比列调整到 608×336,avs 里可以这么写 Crop(8,64,704,352) LanczosResize(608,336) 无黑边的画面的直接用 LanczosResize(512,384) 缩小同时画面强制到标准 4:3 请直接记住这几句就可以了得到最佳的 rmvb 画面大小了![编辑]4.亮度滤镜亮度滤镜是使用 avs 压制 vob-rmvb vcd-rmvb 的又一关键因素。
画面太暗的 rmvb 是失败之作 介绍 2 个 Levels(0,1.5,255,0,255) 改第二个,我感觉数值在 1.3-2 之间比较合适,一般 1.5 比较合适 Tweak(0,1,20,1) 4 个浮点数分别表示:调节色度,饱和度,亮度,对比度。
一般将第三个调节 在 0-30 之间,以 15-20 为宜 个人感觉 level()比较好,主要调背景为主,而 vob 文件主要是背景暗。
注意 Tweak 的其他调节可能和颜色控制环境有关,如 YUY2,因此其它的最好不要再 改动 注:ffdshow 目前的版本还是不能支持 mpge2 唉!否则可以利用它来调节亮度 了[编辑]5.字幕滤镜TextSub("h:\avs\jrvs.ssa") 加载水印文本 VobSub("e:\vob\ss.idx") 加载影片字幕[编辑]6.其它虑镜介绍FluxSmooth(5,7) 柔化滤镜 Convolution3d("moviehq") 3D 优化滤镜 2 者需要加载相应的滤镜插件[编辑]7.常用音频处理脚本ResampleAudio(44100) DELAYAUDIO(XXX,30) AmplifydB(wavsource(“XXX.WAV”),3,3) 例子: DelayAudio(wavsource(”XXX.WAV“),-30)30 的单位是毫秒,经典的解 决音画同步问题; 又如: WAVSOURCE(“xxx.wav”).ResampleAudio(48000) 音频重新采样,采样率 48 再如: AmplifydB(wavsource(“xxx.wav”),3,3) 左右声道放大 3DB[编辑]8.色彩模式的转换有些压缩软件不支持某些色彩模式,例如默认情况下 Helix 不能在 YV12 环境下 工作,需要将 DVD 的 YV12 转为 YUY2 video=ConvertToYUY2(video),当然如果你装了 Xvid,Helix 也是可以在 YV12 下工作的 有如下的转换: ConvertToRGB32()、ConvertToRGB24、ConvertToRGB() ConvertToYUY2()、ConvertToYV12() 简单例子: AVISOURCE(“xxx.avi”) ConvertToYUY2() 等价于 AVISOURCE(“xxx.avi”,“YUY2”)或者 AVISOURCE (“xxx.avi”).ConvertToYUY2() 其他的也类似[编辑]9.截图没有想到用 avs 来截图吧,只要用 wmp6.4 或 mpc6468 播放一下写好的 avs 文 件,截图就产生了 directshowsource("C:\1.rmvb",fps=23.976).ConvertToRGB24 trim(0,19) ImageWriter("C:\",0,0,"jpg") 这里我们假设的是要截取的 rmvb 为 C:\的 1.rmvb,要截取的 frame(幅)从第 1 到 20 共 20 幅(trim 是以 0 为第一幅) 保存路径为 C:\,格式为 jpg(支持 bmp, dds,jpg/jpe/jpeg, pal, pcx 格式) 连续截图 Avisource("C:\test,avi",false).ConvertToRGB24 trim(0,19) ImageWriter("C:\",0,0,"jpg") 截取特定的 frame Avisource("C:\test,avi",false).ConvertToRGB24 trim(1920,1920) ImageWriter("C:\",0,0,"jpg")[编辑]10.合成AudioDub(video, audio) 合成常用于 real 格式的压制,制作 rmvb 的时候就需要把视频和音频合成后交 给 real 压缩软件,而制作 avi 则不需要合成视音频。
