视频转换编码器有哪些 常用到的视频转换编码器介绍
次软件教程
  未经压缩的视频基本上是无法进行传播的,特别的是放到网上更是几乎不可能。视频压缩现在一般是解码后通过编码器对视频进行重编码,以压缩视频体积。今天小编将给大家介绍一些常用的和常见到的视频编码器。
  1、压缩方式
  压缩一般分软件压缩和硬件压缩,这里只说软件压缩。
  软件压缩不是说用什么压缩软件,而是用什么编码器。压缩的方式主要分两种:
  一是对帧和音频进行压缩,对帧的压缩主要是提取视频中的关键帧,并通过某些图像算法对帧进行压缩;音频压缩是指是指降低信号动态以滤除噪声和避免动态过大的失真。
  二是针对各种冗余,表现为除了对段时间内的除了对单幅图像进行编码,还有帧重构,以及利用基于块的运动估计、运动补偿、帧内编码和熵编码等技术,还有去除人感觉不到的图像细节和频段,或通过制造听觉和视觉上的错觉,从而大幅度降低音视频文件的大小。
  2、H.264
  H.264标准的主要目标是:与其它现有的视频编码标准相比,在相同的带宽下提供更加优秀的图象质量。为此,H.264与充分利用了包括统计冗余和视觉生理冗余在内的各种冗余。
  这种压缩方式能够在低码率的情况下提供高质量的图像,并且具有较强的容错能力和网络适应性。这个简单的说就是,H.264编码的视频文件,在相同画质下会比其他编码方式得到的视频文件更小,同时不容易出现花屏或不能播放。但缺点是,H.264的视频相对于其他编码的视频,同样画质的文件,对硬件配置的要求更高。但对现在的硬件而言,基本都只是在将视频转换为H.264的视频是会更慢一点,播放一般都没问题。
  3、MPEG-4
  MPEG-4最开始只是一个视频编解码标准,但现在不只是视频编解码标准,参与者及分支众多,但这里只讨论运动图像专家组MPEG的mpeg-4视频编解码方面,其他不管。这个视频编解码器利用很窄的带宽,通过帧重建、运动估计、运动补偿等技术,压缩数据,以求以最少的数据获得最佳的图像质量。
  在相同码率下,这种编码方式的视频将比其他编码方式的视频有更高的画质、音质,同时具有较好的容错性和网络适应能力,转换出来的视频对硬件的要求也较低。但是由于当前某些技术的限制,在压缩比较高时,会出现色块。
  另外,mpeg-4并不是一个死的标准,它每年都有一定的改进。(不会影响到旧视频的播放)
  4、Xvid
  Xvid(旧称为XviD)是MPEG-4一类的视频编解码器,Xvid支持多种编码模式,支持量化和范围控制,运动侦测、动态关键帧距和曲线平衡分配等众多编码技术。
  Xvid作为世界上第一个第一个真正开放源代码的,通过GPL协议发布的视频编解码器。近五年来,XviD一直是世界上最流行的视频编码器。估计在BT(BitTorrent)和eMule上至少90%的电影、电视剧是用XviD压制的。
  使用的技术不同,视频的质量和大小都不同,一般视频转换器的所使用的xvid编码器,转换出来的视频就画质与大小而言,与转化器中的mpeg-4并无多少差别。
  5、WMVideo
  WMVideo是软件巨人微软的产品,其最新的几个版本的压缩率已经同H.264相当。现在微软的WMA-HD和H.264已成为下一代DVD,即HD-DVD技术的强制执行标准。
  值得注意得是,少数系统或平台不支持这个,同时,容错性与前面几个相对要低一点,而且在网络上的加载速度要比其他标准都低一点。
  6、Real Media
  Real Media是Real公司开发的一种一种高压缩比的视频格式,其最初的想法是用来在低速率的网络实时传输活动视频影像和在极低的网络带宽下提供不间断的画质较高的音视频。
  Real Media压缩标准在相当长一段时间内,其压缩率都居于全球之冠,一度在全球非常有名,在国内也长期占据是使用率最高的音视频编码标准(目前貌似还是)。但是由于该标准本身存在色彩还原度不高(即转换后的视频色彩上有细微变动)、容易出现色块、快速运动图像容易模糊的问题,而且目前H.264、mpeg-4、Xvid、WMV-9及其以后版本等视频编解码器的压缩率都不低于它,再加上这个标准的版权在Real(严重鄙视某几个知名播放器的盗版行为),所以目前这个标准的使用率每况日下。

THE CURRENT STATE OF CODECSThere's much more to visual communication than simply slapping a series of shots together. With video, you need to think about the way you connect your shots.In the February 2010 issue ofVideomaker, we featured an article asking,&What is a CODEC?Due to the subject's complexity the piece was only able to scratch the surface of a subject that to many, is a vast well of technical mumbo-jumbo. This article presents a codec &state of the union& as it were, a revisit of some of the basics as we dig just a bit deeper into this ever-growing topic. We'll explore the variety of codecs available within two distinct families, Apple ProRes and the MPEG family. We'll also look at effective media management through the use of these codecs, and more. Just know that this is a subject on which volumes can, have been and should be written. This article is simply meant to whet your appetite and answer some of those pesky questions you often have regarding which codec is right for you. However, before we get into the details, let's revisit the definition of a codec.What It IsThe word codec is really the combination of two words: coder and decoder which, by the way, is exactly what they're designed to do. Codecs simply encode and compress streams of data for storage or decompress streams of data for playback orediting. Because digital video represents a huge amount of data, codecs are an essential component of the modern day process of video production, yet they're something that many of the most seasoned pros know little about. Let us shed a bit of light on the current state of codecs and how you can maximize their potential in your future productions.Getting From There to HereDigital video begins its life in the form of a codec. You've probably heard the term &native& which is used to&describe the format that your camera records to&and stores the digital data. Sometimes however, the &native& compression is not optimal for editing, usually because the data is just too large or clunky for your computer to process at speeds necessary for a fluid workflow. Therefore, your media needs to be transcoded or compressed into a lower bit rate or one that conforms to your end user's viewing and listening needs. Bit rate refers to the number of bits of information that are processed during a specific unit of time. In video that unit of time is always determined in seconds, i.e. bps (bits per second) or Mb/s (megabits per second).When you compress a file for later use you do so using lossless data compression or&lossy data compression. Lossless data compression means that you are reducing the size of the file by replacing a recurrent sequence of data with a symbol. Doing so means you can decompress that same file and restore it to its original state without the loss of the file's information or overall quality.Lossy data compression permanently takes away some data, allowing the file to be reduced in size and unfortunately, quality. Think of a &pixilated& photo or a blocky video. That is &lossy& data compression and it does not allow for decompression. It's a bit like squeezing toothpaste from a tube, you can't put it back.Now there are all sorts of applications available to compress your video and&audio data&for future use. Almost all editing software comes complete with compression tools enabling you to test out a variety of codecs. There are also a ton of tools available for download but most of them come at a cost. However, one popular transcoding tool that has gained in popularity and is offered for free is a tool calledMPEG Streamclip from Squared 5 srl. This is a robust tool with a seemingly endless menu of settings for transcoding your data. MPEG Streamclip, by virtue of its price alone, is a great tool for testing various compression settings and seeing which ones work best for you, your devices and your end users.The Most Common CodecsWhile the list of usable codecs is about as long as your arm, there are codecs that can be categorized as &most commonly used& among professionals and hobbyists alike. The following list outlines a couple of those codec families and some information detailing the specific applications of each.ProRes CodecsWhen Apple decided to dive into the world of video and film post-production they developed a unique Apple umbrella codec with five different versions to suit almost any editor's specific needs.Apple ProRes 4444&- For those wanting full resolution color mastering in RGBA (Red, Green, Blue, Alpha), the ProRes 4444 is a fantastic codec. ProRes 4444 slightly compresses the color channels but the difference is almost indistinguishable. This is also a great codec if you're working with alpha channels since it supports everything from SD to 4K resolution.ProRes 422 (HQ) and ProRes 422&- Both of these codecs work well with i video and handle a 4:2:2 or 4:2:0 color space respectively (no alpha channel) without difficulty. The major difference between the two is that (HQ) has a target data rate of close to 220 Mbps while regular ProRes 422 can only handle as much as 145 Mbps.ProRes 422 (LT) and ProRes 422 (Proxy)&- If you're wanting to view video using the original acquisition frame rate, aspect ratio and frame size - (LT) and (Proxy) are suitable choices. The major difference between the two is in their data rate. Using ProRes 422 as the standard, (LT) is about 70 percent of the 422 data rate while (Proxy) is around 30 percent and geared for offline workflows. These compressions result in smaller file sizes and are considered good for work-in-progress files. Most Final Cut Pro editors utilize the ProRes 422 (HQ) and the ProRes 422 because they're still able to maintain decent resolution and the 4:2:2 color space is actually closer to what the human eye is able to register. Therefore, the difference between4:4:4 and 4:2:2&, while technically large, is not so prominent with respect to how we see color.The MPEG Family:In that What is a CODEC? feature, we reviewed several compression schematics from the MPEG family, MPEG-1, MPEG-2, MPEG-4 or H.264 and so on. Each one is different and each has its own advantages and disadvantages. So, how do you know when to use which one - and why?MPEG-1&is a codec that is accepted across a variety of distribution channels, meaning, it is compatible with most hardware-based and software media players. Because it has a low bit rate compressing with MPEG-1 allows you to fill several hours of media on a DVD at fairly high quality.MPEG-2&is a full-frame compression at 720x480 - NTSC and 720x576 - PAL. It is a popular compression standard for DVD distribution rather than streaming&via the Internet&since it requires a high bit rate to maintain picture quality (somewhere between two and nine Mb/s). Many encoders will allow you to adjust the bit rate to accommodate the amount of media you want to store or play on a DVD. For instance, if you're working with a 4.7GB DVD, an average bit rate of 3.5Mb/s would allow for close to 120 minutes of space whereas a higher bit rate of say, 6Mb/s would allow for around 80 minutes of play time.MPEG-4, also known as H.264 is a continually developing codec, especially with the advent of MPEG-4 Part 10 which provides four times the frame size at a given data rate as does MPEG-4 Part 2 which has blossomed in the world of Internet viewing. Because it uses a one-pass variable bit rate (VBR), MPEG-4 maximizes output for mobile devices such as laptops, smartphones and more.Want to know more?As stated near the beginning of this article, this is a topic on which volumes of information has been and will be written. There is so much to digest, understand, and explore that we can once again only scratch the surface. No matter which codec you're using, we urge you to take time to test the ones that work best for your most common applications. Just like with anything in life, the more you explore, the more you practice, the more you utilize compression tools in your video, the more familiar you will become with their individual design and intent.Sidebar: Calculate File SizeAt first, attempting to calculate a compressed file size is a bit like asking you to look into a crystal ball. But rest assured - there's a formula for determining just how many bits or bytes your compression will be. You can calculate using either bits or bytes.Here's just a bit of information to refresh your memory:Megabits processed per second may be written as Mb/s.kb/s is the abbreviation for kilobits per secondThere are eight bits (b) in a byte (B).There are 1,000 kilobytes in a megabyte, and a kilobyte is 1,000 bytes, so a megabyte is 1,000,000 bytes.As for how to calculate length of a compressed file you can employ the following formula:&For bytes, employ this formula:&x = length of media (seconds)&y = bitrate (kilobits per second) x 8&z = resultant file size (kilobytes)&(x * y) / 8 = z*NOTE: You divide the multiplied result of x times y by 8 since there are 8 bits in a byte.Now, like all good adopters of the digital age, if you don't feel like doing the math - use a calculator! You can calculate your file sizes by using a tool from Digital Rebellion, the video space calculator. It's a simple but extremely helpful tool.Chuck Peters is a 3-time Emmy award-winning writer and producer. He is currently VP of Production at KIDMO/Rivet Productions.

简单介绍下bandicam的几个视频编码器吧,似乎没见到帖子介绍收藏
没看到吧里有这样的帖子,简单说一下这几个编码器是怎么回事吧,让不明白的朋友不至于迷茫。1:RGB24R:red G:green B:blue,即红绿蓝色光三原色,24代表用24个比特(bits)表示一个像素,即红色8个比特,绿色8个比特,蓝色8个比特,也就是说用3个字节表示一个像素的颜色,也就是无损图片BMP使用的存储格式,这种编码器意味着无损捕捉,因为它将捕捉到的每一帧保存为一个BMP图片,容量也可以简单的计算出来,以640*480图片为例,3个字节为一个像素,640*480的BMP图片的容量大约为640*480*3=979200字节,/MB,大约1MB一张图片,如果视频帧率为30FPS,1秒钟的RGB24录出来的视频容量接近30MB,是一个非常巨大的数字,录上一段时间硬盘不够也是很正常的事。2:MJPEG也是大家热议的一个话题,MJPEG与RGB24相比,相当于每一帧由无损BMP图片压缩成为有损压缩JPG图片,JPG容量与量化质量有关,一般大约为BMP图片的1/10左右,也就是说用MJEG录视频与RGB24相比可以节约大约10倍的空间。3:YV12表示一个像素点的颜色除了RGB之外还有很多表示方法,YUV就是其中最常见的一种。Y代表像素点的亮度,UV分别为两个色差分量。YUV这种色系最早被用来电视信号的传输,为了兼容老式的黑白电视出现的,只有亮度分量Y就是黑白图像,就解决了黑白电视兼容的问题。与RGB色系相比,YUV最大的好处就是便于传输与压缩,肉眼对亮度比较敏感,而对色差敏感度相对较弱,因此传输可以完全保留Y,大量压缩UV来达到高压缩率,因此这也是数字视频所采用最多的一种色系,绝大多数视频编码都是用的YUV色系压制得到的。YV12就是YUV色系按照4:2:0采样得到的一种编码,容量比RGB24小得多。4:MPEG-1RGB得到的视频容量很大,所以需要压缩,MPEG组织就是为压缩视频和音频容量诞生的组织,专门制定多媒体压缩标准。它们制定的第一个国际化标准称为MPEG-1,规定了视频和音频的基本编码表示。与最早的视频会议采用的H.261标准相比,MPEG-1增加了双向预测帧B帧,容量大大压缩,大约压缩的容量为RGB的1/40,是最早为VCD提供的编码,VCD视频采用的就是MPEG-1的标准。5:XVID给予MPEG-4标准诞生的产物,与以前的MPEG-1,MPEG-2标准相比,MPEG-4标准增加了更多的细节描述,对视频的压缩比控制的更好。XVID自诞生以来就受到国外压片者的亲睐,具有压缩率高,压缩速度快,压缩质量好等优点,那时候的互联网视频大多数都是压制为AVI格式,XVID成为了AVI最主要的编码之一。音频编码一笔带过PCM:即无损音频WAV采用的编码,也就是说录制这种AVI的音频编码相当于wav,容量很大,但是由于使用波形存储,不需要解码,消耗硬件资源小,播放速度快,兼容性好。MPEG-1 L2:即MPEG-1 layer 2,MPEG-1标准中对音频定义的第二层,也就是MP2编码(MP3为mpeg-1 layer 3,第三层),过多的不用多说,mpeg-1标准为音频定义了3个层,一层比一层压缩率高,一层比一层音质好,同样,一层比一层压缩花销大。
编码器本身并没有优劣之分,看你要怎么用了。bandicam默认使用MPEG1,是兼顾了容量与压缩速度的选择,中等配置的PC可以考虑XVID,画质不错,压缩率也高。自己想后期压缩制作处理推荐选无损的那几个,我一般用YV12。
压制和显卡无关,不消耗显存,压缩占用的是CPU。我一般录制YV12压制H.264
换老版本试试,那个百度贴吧最终版不错,后面的版本我录制窗口似乎也会卡死。尝试不锁定帧数录制,将录制帧率设置到60FPS
我的设置,一般还是不会卡的。实在是硬盘速度跟不上的就选择有损压缩的那几个吧。
本身就没那么高的分辨率,你非要拉伸那么高,肯定会出问题
一般来说,分辨率只能缩小,不能放大,除非是有特别需求的。分辨率从片源得到是多大就一直保持就可以了,想当然的拉大分辨率不会对画质有丝毫的提升,甚至可能浪费了大量不必要的容量,反而因为插值拉伸画面的缘故造成画面模糊。你可以比较下试试,原始素材是640*480,你录制成640*480全屏观看,和你直接按照全屏分辨率录制出来的视频不会有丝毫画面上的差异,但是两者相差的容量不是一星半点的。
干嘛非得看优酷的脸色,它不给你好脸色你也别给他好脸色,它要给你的视频加水印盖它的戳子你干脆别鸟他,优酷这种渣画质的玩意,乱转码破坏视频,垃圾网站不改版绝对不用。几年前用过一次,一看强制转码加水印就再也不用了。几年后一看还是那个鸟样子,就彻底放弃了。
现在不用战了,基本上1000kbps的H.264+AAC就OK,不过封装必须用flv,如果是mp4的需要用ffmpeg转一下封装。
据我所知,想压缩10bit的人基本都是靠裸压。MC里面带有x264 10bit版,但是调用的话需要手动在命令行额外加入10bit命令参数。megui也有10bit的x264.10bit目前比较流行,但是和8bit相比并不具有明显的优势,10bit也不是什么新技术新玩意,为了兼容性还是选择8bit吧。
记得以前有人比较过,在暗场比较下,10bit并不比8bit有优势,甚至还有所不如……
想偷懒就用megui和mc,一些特殊的视频就自己写x264参数裸压了。我的视频基本上是给我的MP4压制看的或者上传到在线视频网站上,为了兼容性几乎不选10bit。10bit也没研究太多,只是以前看过dwing介绍与比较。听说10bit压动漫之类的片源效果很好,颜色还原度较高,所以压制动漫用10bit的很多,其他片源用10bit的并不多
用mediainfo查看,编码显示fraps是无损捕捉,更接近于RGB
检查下你有没有打开麦克风音量与音轨。其次确定你的声卡是否支持多声道同时输入。不过一般不建议你多声道输入,即使声卡能支持,声音效果也很差。你可以录制好之后自己录制自己的解说加进去后期制作
