Another Solution to Play AVI - Get QuickTime Component: Perian

The QuickTime player is mostly used in Mac OS, if you don't want to use the first solution to convert the AVI files to QuickTime compatible formats, you can try this solution, but no 100% work guarantee.

Perian, is a great open-source QuickTime component that allows playback of different video formats that cannot be played natively on your Mac computer. If you want to use QuickTime as your main video player, you may choose to download Perian because it provides the necessary codecs or components that will allow you to play AVI on Mac. If you have QuickTime 7, you may be glad to discover that it can actually play AVI files without needing any additional plug-ins and codecs.

What you need to know before downloading Perian:

  • The latest version 1.2.3 of Perian doesn't work on Mac OS X Mavericks because Perian requires installation of quicktime 7, which doesn't exist for Mavericks. It also doesn't work on Mac OS X Mountain Lion.
  • With a Mac running Mac OS X 10.7, say, Lion, you have to downgrade to the previous version, say 1.2.2. The version of 1.2.3 of Perian does not support QuickTime 10 in Lion and fails to fix the loss of audio after one second in xvid files with ac3.
  • Before installing Perian, you need to remove all QuickTime Components installed on your Mac, like FFusion, Xvid Delegate, 3ivX, DivX, DivX Decoder, XviD, msmpeg4v1, msmpeg4v2, AviImporter, EX_M4S2, Casio AVI Importer, AC3 Codec, and MatroskaQT.
  • For a Mac running Lion or Mountain Lion, converting AVI video to QuickTime is highly recommended.

Tips: Switch to Other Media Player for AVI Playback

The VLC media player, is an excellent open-source media player that is known for supporting a wide range of audio and video files. Unlike other media players which have limited format-support, you will be surprised that VLC can play a video or audio file that you didn't even know existed. If your OS is Snow Leopard or higher, installing VLC is definitely a good choice especially if you only plan on watching AVI files on your computer.

Cons of this AVI player (VLC media player):

  • VLC player doesn't play AVI videos with high qualities.
  • VLC player doesn't support Mavericks.
