My QuickTime player us not playing .avi files and says I need a codec I can't play no .avi files on QuickTime. How could I fix this because I want to play these files with QuickTime.
MacBook Pro, Mac OS X (10.7.3), MacBook Pro 2.8 GHz Intel Core i7.
There is no single codec for movies that have .avi extensions. AVI is a container format, not a specific type of file. An AVI movie may use one of the Indeo codecs (there are at least four that I'm aware of, none of which have been ported to Mac OS X) or one of the various flavors of DivX, among other possibilities. You'll have to find out what codec was used for the movies you want to view to determine what you need. Note that not all codecs for the various .avi movies are available for QuickTime.
If you want to try "hit and miss", Perian, which rolls several codecs into one package, might work. If not, you can try the codecs at http://www.divx.com/ and http://www.3ivx.com/ and see if one of them will work for you. Do not install both Perian and the DiVX/3iVX codecs at the same time.
If you just want to play the movie any way you can, you can also give this player a try:

Why QuickTime Won't Play AVI Files?
AVI (Audio Video Interleaved) is a container format designed by Microsoft to wrap audio and video stream together. The video in AVI file can be compressed by many kinds of codec, such as MJPEG (Motion JPEG), MPEG-1, MPEG-2, DivX, XviD, WMV and others. To play all AVI files, your player must support all of these codecs. So far, no matter you are a Windows user or a Mac user, QuickTime only natively plays AVI files with MJPEG video.
As a great open-source QuickTime component, Perian is the saver to allow QuickTime to play all kinds of AVI videos for Mac users. Unfortunately, the latest version 1.2.3 of Perian is not compatible with Mac OS X Mavericks (10.9), Mountain Lion (10.8) and Lion (10.7).
In order to solve "QuickTime won't play AVI" on Mac (Mavericks included) and Windows, it is best to convert AVI to QuickTime more popular formatslike MP4, MOV.
Hope it will help you more or less.
Hello there, I am new here. I found this is a search for the same problem. I just did the Yosemite update and now my QuickTime player does not work at all. I was working just fine before the update and played all file types with out any problem but now it keeps saying converting or wont play anything. I am a novice here so am I to understand that QuickTime no longer works at all and I have to now convert all my .AVI files over to mp4 or something? I am confused to why quicktime is no longer working? Will apple fix this or is this just a problem with the new update? It also seems as though my computer is running slower now too since the update. I hear there were alot of issues? I wish I would have known that before doing the update.
Anyways any help or step by step info for fixing the quicktime issue would be helpful. Thanks, -Dave
