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.

Note: macOS will soon no longer be able to run 32-bit programs. This means QuickTime Pro 7 won't run fine on the new OS after Mojave. You have to find a replacement to play the video or convert AVI video to MP4 format that other portable devices accept.

Apple apps such as QuickTime Player, Photos, and Keynote work with many kinds of audio and video formats. Some apps prefer specific formats, but QuickTime movie files (.mov), most MPEG files (.mp4, .m4v, .m4a, .mp3, .mpg), some AVI and WAV files, and many other formats usually work in most apps without additional software.
Older or specialized media formats might not work in your app, because the format requires software designed to support it. If that happens, your app won't open the file or won't play back its audio or video.
How to search for an app that works with your file
You might already have an app that supports the format of your file. If you don't know which of your installed apps to try, your Mac might be able to suggest one:
- Control-click (or right-click) the file in the Finder.
- From the shortcut menu that opens, choose Open With. You should see a submenu listing all of the other installed apps that your Mac thinks might be able to open the file.
If none of your installed apps can open the file, search the Internet or Mac App Store for apps that can play or convert the file:
- Include the name of the media format in your search. To find the format, select the file and press Command-I to open an Info window. The format might appear after the label Kind, such as ”Kind: Matroska Video File.”
- Include the filename extension in your search. The extension is the letters shown at the end of the file's name, such as .avi,.wmv, or .mkv.
