原文: AVI vs MP4

AVI is far better than MP4. Video content in AVI boasts better quality. This can be proven by viewing AVI files using most digital video players.

 Unlike MP4, AVI isn’t readily supported by DVD players. Nevertheless, video content in MP4 is grainy at larger viewing resolutions, again making AVI a better choice.

MP4 format is Apple’s version of video encoding. This has only existed in the media world since 2000/2001, and it is included free with many systems. HD TV has used MP4 to broadcast its signals in order to make the transmissions easier and relatively inexpensive.

AVI, like MP4, is what you would call a “container” format. The nickname applies quite well to AVI because within this particular file format, you can encode both audio and video streams. These include other video stream formats such as MPEG4, MPEG version 2, and DIVX.

MP3s and audio MP4 work the same way by compressing large chunks of video into a smaller or more portable file. This makes the file much easier to work with. These files are compressed into smaller ones without loss of quality. The MP4 players that are used to view the MP4 format are fairly simple. The file is viewed in DVD quality. This also allows the fast and seamless streaming of video possible.

AVI doesn’t specify how it should be encoded. With this, you can encode the video streams of varying formats to AVI in order to be viewed across a wide array of players. Common formats nestled inside the AVI container include ASF, M-JPEG, and DivX. However, AVI files need the proper codec in order to be viewed.

You can also encode AVI files with user-defined passwords. This makes the format ideal for those who sell private content. However, the biggest annoyance of the AVI format is the fact that codecs are required to play the content. This means you have to download something else in order to view such AVI files unless you already have the appropriate codecs installed.

译文: AVI对决MP4

      AVI格式远比MP4格式好。AVI格式的视频内容拥有更好的画质。这可以通过使用大多数视频播放器观看AVI格式来证明。
      不同于MP4格式，DVD播放器通常不支持AVI格式。然而MP4格式的视频内容在较大解析度下观看时会出现条纹，这就再一次使得AVI格式成为更好的选择。
      MP4格式是苹果公司的视频编码版本。这只是从2000/2001年才开始出现的，而且它对很多系统免费开放。高清电视就使用MP4格式去传送信号，使得传送过程更加简便和相对的便宜。
      AVI格式，就像MP4格式一样，是一种我们叫做“容器”的格式。这个绰号对于AVI格式是相当的贴切，因为在这种特别的文件格式里，你可以同时对视频和音频流进行编码。这些包括其他视频流格式，比如说MPEG4,MPEG2和DIVX。
      MP3和音频MP4原理是一样的，都是用过把大的视频压缩称更小或者更方便处理的文件。这使得文件处理起来简单得多。这些文件被压缩成更小的容量，而不损失画质。用来观看MP4格式的MP4播放器其实是相当普通的。这些文件可以以DVD画质来观看，同样也使得快速而无缝的视频流成为可能。AVI格式不特别的规定应该如何编码，这就是说你可以把不同格式的视频流编码成AVI格式，使得可以应用多种不同的播放器进行观看。AVI“容器“内含的常见格式包括ASF,M-JPEG和DivX。虽然如此，AVI文件还是需要合适的编译码器来进行观看。
      你也可以使用用户自定义密码来对AVI文件进行编码。这对那些销售个人隐私内容的用户是理想的格式。不过，AVI格式最大的困扰是需要需要编译码器来播放视频内容，这就意味着除非你已经安装了合适的编译码器，否则你就不得不去下载编译码器才能观看。
