The AVI format is usually seen when people try to open some media files of audio and video. Since it is so common, there is some information about the AVI format you should learn. As some error or warning windows can pop out if you just click on an AVI movie via Mac laptop, the primary questions you want to figure out are why and how to play AVI movies on Mac. You may also consider an AVI movie player for mac. Hence, we can troubleshoot how to watch AVI movies on Mac by three handy methods.

Part 1: About AVI

While the AVI is representing the Audio Video Interleave, which is a file format used as a container for video and audio data. It is designed and developed by Microsoft in 1992. Since this format can store both audio and video content in a single file, the compression can be done with a large variety of codecs. The AVI format file leans on the Resource Interchange File Format, which is another storage format for multimedia contents. While it is frequently opened and played by the Windows Media Player, it is deemed to be one of the trendiest media file formats.

Although the codec packs support the compression with diversity, yet the multimedia contents will be compressed significantly less than other popular formats such as MOV and MPEG. As the MOV can also be difficult to open and play on Mac, there is also a way for playing MOV format files online. In this way, you will find that the single MOV or MPEG file is much smaller than an AVI file. Some further information that you don’t want to miss about the MPEG format is that the MPEG files include different compressions of either MPEG-1 or MPEG-2. Due to the flexibility of the MEPG file, the video contents can be easily streamed through the internet. It is likely to be questioned about how to import MPEG files into iMovie so that you can watch MPEG videos on Mac, well you need to get the compatible MPEG formats so that the iMovie can recognize.

There might be a couple of reasons for having trouble opening the AVI files because of the huge diversity of audio and video codec. When the media contents are encoded into AVI format files, you might think they could be played by most players. The truth is, it is not correct as every AVI file are not installing with the same codecs. Or the media player you have does not support all the AVI codecs. Specifically, people using the Mac operating system are experiencing inconvenience playing an AVI file. We have detailed explanations in the next part.


Part 2: Why You Can’t Directly Play AVI Files on Mac

Windows Media Player has the ability to decode AVI format files in most versions. Yet it could still have the chance that the Windows Media Player won’t play a certain AVI file. Once the lacking codec installed, you are probably able to keep playing AVI files. However, as we all know that the Mac system has its integrated media player, QuickTime, the default media player will automatically pick up your commands on playing AVI movies each time. Then it failed all the time. Why your Mac cannot directly deal with AVI files and show the error windows? Sadly, for all Mac users, the principal reason is that AVI files are not able to play in QuickTime. To be more informative, QuickTime doesn’t contain the decoding process for AVI format files.

So what can we do under the situation that Mac computers can’t accept AVI movies while the popular AVI video files are approachable everywhere? There are three practical means you can make full use of to troubleshoot this irritating issue. First of all, a professional AVI movie player for Mac sounds ideal and reasonable. The second method is to convert the AVI movies to MOV/MP4 media files so that QuickTime can identify and play AVI movies on Mac.
