Although QuickTime 7 and QuickTime X (QuickTime Player v10.x) structure embeds are AVI compatible, QT X AVFoundation only recognizes AVI files that include Motion JPEG encoded video with PCM audio. Therefore, the playback of AVI through QuickTime on Mac or PC's will mostly depend on the type of compression (or codec) of the AVI itself. A good QuickTime player alternative!

AVI or Audio Video Interleave was developed by Microsoft as the file format for its media player application. It is an old container. MOV was developed for Mac OS and QuickTime application by Apple. MOV supports MP4 codecs like H.264 while AVI does not.
On the Internet, where the compatibility demands are high, AVI had become very popular. This format is supported by almost all players, even portable devices like video players and video smart phones. Because of the growing needs of the users of this format, Microsoft abandoned AVI container and launched WMV with newer and more features but for the later version of the Windows Media Player.
The AVI container has no native support for modern MPEG-4 features like B-Frames. Hacks are sometimes used to enable modern MPEG-4 features and subtitles, however, this is the source of playback incompatibilities.

AVI files do not contain pixel aspect ratio information. Microsoft confirms that 'many players, including Windows Media Player, render all AVI files with square pixels. Therefore, the frame appears stretched or squeezed horizontally when the file is played back.'
More modern container formats (such as QuickTime, Matroska, Ogg and MP4) offer more flexibility, however, projects based on the FFmpeg project, including ffdshow, MPlayer, xine, and VLC media player, have solved most problems with viewing AVI format video files.
While the AVI format has been superseded by more advanced formats like MP4, MOV or WMV, people continue to use AVI because of its universal portability. AVI files can be played on almost any computer or device (unless the format has been hacked for supporting MP4).
The QuickTime (.mov) file format functions as a multimedia container file that contains one or more tracks, each of which stores a particular type of data: audio, video, effects, or text (e.g. for subtitles). Each track either contains a digitally-encoded media stream (using a specific codec) or a data reference to the media stream located in another file. Tracks are maintained in a hierarchical data structure consisting of objects called atoms. An atom can be a parent to other atoms or it can contain media or edit data, but it cannot do both.
The ability to contain abstract data references for the media data, and the separation of the media data from the media offsets and the track edit lists means that QuickTime is particularly suited for editing, as it is capable of importing and editing in place (without data copying). Other later-developed media container formats such as Microsoft's Advanced Systems Format or the open source Ogg and Matroska containers lack this abstraction, and require all media data to be rewritten after editing.

Can QuickTime Play AVI Files?
AVI is on the list of QuickTime supported video formats. But this is only limited to the AVI with Motion JPEG video. You will encounter various codec problems when playing AVI on Mac as follows:
1. If you get the message 'filename .avi file could not be opened. A required codec isn't available.' You shall understand AVI, in fact, is a kind of container format, which can be compressed by a number of codecs, including MJPEG, MPEG-4, MPEG-3, MPEG-1, MPEG-H etc. QuickTime can't play AVI video compressed with MPEG-4, MPEG-HD etc other than Motion JPEG video.
2. QuickTime can't play AVI file with audio sound. QT does not recognize the audio in this video because the audio codec is not supported by QuickTime.
3. Some users reported that QuickTime no longer played AVI file after having updated to new Mac OS X. The installed codec or Perian are the issues that cause AVI file not playing on QT. Perian may not be compatible with the new OS you upgraded to.
