Watch AVI video on a Mac

watching avi on mac

You can watch many AVI movies without any additional software on a Mac just by playing them in the included QuickTime Player (located in the Applications folder). Just double click the file and it should work.

But what if it doesn’t? There are situations when AVI movies won’t play at all, and you might get an error message like the following:

play avi on mac
“The document “movie.avi” could not be opened. The movie is not in a format that QuickTime Player understands.” Followed with some fine print “You may need to install additional software to open this type of file.”

There are also times when just the audio of an AVI doesn’t work and sometimes just the video won’t work, in these cases it’s likely because you need to get a particular codec on your Mac to watch the AVI file.

In any of these cases the best solution is to get the AVI to play on your Mac is to just download a free plugin for QuickTime Player called Perian. Perian covers many codecs and will almost certainly allow your AVI file to play in the Mac QuickTime Player.

* Quit out of QuickTime Player if it’s open
* Download and install Perian (it’s free)
* Launch the original AVI movie back into QuickTime Player

The video should now play trouble free within QuickTime Player. You could always convert the AVI to MOV as well but you’d still need to download Perian for that.

If you’re looking to play DIVX on a Mac, I would highly recommend using Perian as well, it’s really the best solution.

    So where’s the “without any additional software” when the whole article is about installing a software?
    Isn’t it better to just forget about the horrible Quick Time Player?

      QuickTime Player opens many AVI movies without Perian, it’s only particular codecs that it won’t support.

      If you have any suggestions for an alternate video player, post away. Since development on VLC for Mac has stagnated I am hesitant to recommend it as a solution.

        Not sure why you say Mac development for VLC has stagnated. A posting on their site http://www.videolan.org/ dated April 21 states that version 1.06 for the Mac will soon be released, which will bridge the gap between the current 1.05 (released in January) and the up-coming version 1.10. VLC works beautifully for me and I have it installed on 20+ Macs in our studio.

    When I first started reading this article I thought it was going to be about the Apple page where you can obtain QT codecs and plugins and junk.

    @jakub, QT isn’t really horrible at all. Overall it’s hight versatile and functional. It has allot of really great features and functionality, aside from being the foundation of iTunes. Pretty good basic video editing functions, great export and video conversion functions. QT is actually pretty powerful if you take the time to get to know it.

  4. Ufortunately Perian is terribly slow.
    VLC has much better performance.. but anyway king of performance is Movist and the best is to stick with this.It’s first player that on my MBPro plays well compressed 1080p videos without glitches.

  5. [...] load at all, this is probably not syncing but rather a codec issue. If you run into this, learn to watch AVI video on the Mac using something like Perian that has a wide codec support. In most cases, VLC will play the movie [...]
