AVI, Audio Video Interleaved, is a multimedia container format introduced by Microsoft as part of its Video for Windows software. To open AVI files, your player must support all of these codecs. But Mac's built-in video player - QuickTime is unable to recognize and play AVI files. 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. AVI File Transfer Errors: Interruptions or errors while transferring AVI files from mac system to any external storage media or visa-versa may results in corruption of AVI video files Synchronization Error: If the audio and video streams of AVI file are not properly synchronized, then it tends to incompatibility issue and finally results in AVI.
AVI may be a very prevalent video format, however, it is not one of the formats specified on the natively compatible file list of Apple iOS and macOS. If you have some AVI files from your digital camcorders or downloaded from the internert and want to edit them in iMovie, Final Cut Pro or play them on iPad, iPhone, etc., transcoding AVI to MOV will be a wise choice since MOV is a natively highly compatible format for all Apple products. In this article, we will show you a quick and easy solution to encode AVI file to MOV format on Mac OS X (incl. macOS Big Sur).
PS: Actually, Apple only supports a couple types of seldom-used AVI file: 'Motion JPEG (M-JPEG) up to 35 Mbps, 1280 by 720 pixels, 30 frames per second, audio in ULAW, PCM stereo audio in .avi file format'. If your AVI files are much more common AVI file type, encoded with a codec that QuickTime can't recognize, like DivX, XviD, you'll need to convert AVI to MOV or other Mac compatible formats for further editing or playback.

My QuickTime player is not playing .avi files and says I need a codec. I am not able to play any .avi files on QuickTime. How could I fix this because I want to play these files with QuickTime?
Playing AVI files is one of the biggest worries for a Mac user. None of the four major Indeo codecs that are required to decode AVI files have been integrated into QuickTime. In some cases, even if the required codecs are available, the AVI video file does not play due to corruption. So, before we get to know how to play AVI files on Mac or how to fix AVI files that are not playing on Mac, let’s get a quick look at Audio Video Interleave (AVI) format.

Why AVI Files don’t Play on Mac?
Just like any other media player, QuickTime on Mac also examines both the audio and video codecs within the video file whenever you open any file on Mac. If the codecs are not used by the media player it won’t play the video. QuickTime media player does not recognize the Cinepak and ALaw 2:1 codecs used in the AVI video file format. And as a result, when you try to play AVI files in QuickTime, the player doesn’t play the video.
Editing Avi Files On Mac
What is an AVI file?
The full form of AVI is Audio Video Interleave. Like any video file format, AVI is a container format that defines how video data is packed into a file. Unlike other video formats, it does not predefine or specify the protocol or procedure involved while recording or creating a file. As an AVI file structure has the organizational format of streams and stream data, it is defined by two lists namely List Chunk and Index Chunk.
List Chunk: The list chunk has metadata, the size of the file, frame rates, and audio/video information.
Index Chunk: The index chunk is responsible for saving the locations of data within the container.
Note: If any of these crucial chunks are missing in your AVI video file, then your AVI file will not play.
What is a Codec?
A codec that is short for compressor and decompressor is responsible for decoding the video and audio tracks that have been encoded or packed in the .avi file.
It is to be noted that an AVI file or any video file does not come with codecs. Codecs are a part of the video player package like QuickTime.
However, if the codec used to encode the AVI file is not available in the QuickTime player, then your AVI file will not play. Thus, you can expand the codec library of the player by downloading the specific codec required to play the AVI video file.
Problems Associated With Running AVI on Mac Using QuickTime
When an AVI file is opened using QuickTime player, it scans the file to see which codecs have been used to encode the data in the container/AVI file.
How To Play Avi Files On Mac Free
The AVI format video will play as expected if the video and audio in the codec are compressed using a codec that exists in the QuickTime package. Nevertheless, problems arise while playing AVI files on Mac when the codec does not exist in the library and leads to an unplayable AVI file on Mac. The file may also refuse to play if the AVI file is corrupt. Fix corrupt AVI files on Mac before trying any workaround.
Unplayable AVI Files Return The Following Errors:
- “QuickTime is missing the software needed to perform this operation. Unfortunately, it is not available on the QuickTime server”
- 'You may experience problems playing a video track in 'file.avi' because the required compressor could not be found”
Additionally, the latest version QuickTime X does not have a few major codecs like Indeo or native DivX support and you might end up with the question “How to play unplayable AVI file on Mac?”.
Now that you have understood the complications associated with AVI files that are unplayable on Mac, the following workarounds mentioned below have been provided to help you fix if Mac or MacBook not playing a video.
Methods to Fix Unplayable AVI files on Mac
1. Find the Right Codec to Play the AVI File on QuickTime:
Find the codec used to encode the file using QuickTime by opening the file using QuickTime and select the Show Movie Info option from the Window menu.
The video file information is listed, and you will be able to find codec information after format properties. Check if the QuickTime version supports the codec that is listed in the video properties.
Check on the QuickTime support site if the codec is supported by the player if you don’t find the codec preinstalled with QuickTime. If you don’t find the respective codec or if it is an unsupportive codec, then your AVI video won’t play. In case it is supported then you can go ahead and install the codec after downloading it from the author or the publisher’s site.
Note: Download the codec from genuine and trusted sources to avoid compromising your system security.
2. Download and Install Standardized Video Encoders
There are two major industry-standard codecs for Mac that can extend the playback capabilities. The following codecs have been referred to as the most preferred codecs that enable you to open .avi files on Mac:
- Install 3ivx D4 codec:
This codec enables greater video quality at lower file size values up to fifty percent when compared to the MPEG-4 standard designed by Apple. This decoder increases the efficiency of the video storage and transmission of files that are rendered too large. It is an integration of a huge set of video and audio codecs that allow playback of almost all the AVI files with AAC audio and video of MPEG-4. You can fix your unplayable AVI file by installing 3ivx D4 on your Mac. Further, there is no need to download any other components like plug-ins to play the AVI file unless a proprietary codec is used to encode the file.
- Install DivX for Mac free codec to fix AVI files in Quick time:
While you can play the majority of AVI files after you install this free codec for Mac, its major disadvantage is that the audio sometimes might be distorted or only the video is played. For this reason, the DivX codec for Mac is a secondary option when compared to 3ivx D4 codec.
Note: Only one among the above two codecs are to be used at once as they share the same set of library files to decode the video. Hence it is recommended to install only one codec to avoid malfunction of the QuickTime player.
3. Use an Alternate player to Play AVI files on Mac:
VLC or Video LAN Client is a cross-platform media player that supports a wide variety of AVI video and audio codecs. Therefore, choosing VLC as an alternative media player to play the unplayable AVI file on Quick Time is one of the easiest ways.
Because of its large library of free encoding and decoding libraries, you will no longer need any additional codec download or proprietary plug-ins.
4. Play AVI Files By Converting Into QuickTime Supported MOV Files:
Another workaround to fix the unplayable AVI video on Mac is to convert the AVI file into a QuickTime supported file format like MOV.
Post conversion, the file will be playable on Mac. However, most of the converters break the index of the AVI file while conversion, this method is least recommended. Lastly, if the converted video file stops playing halfway try AVI index repair on Mac.
Note: Have a copy of your AVI file before converting them to any other compatible format as your AVI file might get corrupt due to improper conversion and leads to permanent inaccessible AVI files.
AVI Still Not Playing In Mac?
If the AVI video file remains unplayable even after getting the correct codecs, using the compatible player, or converting to MOV, it is probably because the video file is corrupt. The only solution to this is to try an AVI video repair software. Choose a professional AVI video repair tool like Remo AVI Repair.
