December 2, 2020

AVI has been and remains one of the most popular video file formats. It's used to encode many TV shows and movies, along with many other video files in a format that many users can play. Unfortunately for Mac users, AVI isn't always the best file format because of the lack of support on devices such as iPhones, iPads, and iPods. While some Mac users may be able to play AVI files on their computers, they will only be able to do so if the files use QuickTime codecs. Apple devices are compatible primarily with MPEG-4 (MP4) and other multimedia formats. This means you will need to convert AVI to MP4 on a Mac or convert them to other Apple-supported formats.

To help you play your favorite movies, TV series, and other AVI files on Mac systems or other devices, the following is a complete guide for how to convert AVI to MP4 on a Mac. Mac users should be able to easily convert AVI files using the following software, including both third-party and native apps.

How Do I Convert AVI to MP4 with QuickTime on a Mac?

If you want to convert a video file using what's already included on your Mac, convert AVI to MP4 with QuickTime Player Pro. This program is Mac's built-in video player that functions as more than a player. Many Mac users aren't aware of QuickTime's myriad capabilities beyond playing video files—for instance, it can also record your screen, serving as free high-quality screen recording software. While it can't play every video file, such as AVI and MKV, it's incredibly easy to use as a built-in video converter. However, bear in mind that you will need to pay for the Pro version to use it as a versatile video converter, as this function isn't included with the free version.

Once you've upgraded to the Pro version of QuickTime Player, you can begin converting files in AVI and other formats. The following is a brief guide to help you convert an AVI file to MP4 on your Mac computer using QuickTime Player Pro.

  1. Start by opening QuickTime on your Mac, either by double-clicking on the video file you want to convert or opening the program alone.
  2. Once open, you can open your video file from the File menu and accessing the file on your computer. If you used that file to open QuickTime, proceed to the next step.
  3. After loading the file, go to the File menu and select the Export submenu from there. Choose the MPEG-4 file format, and click Save. At this point, QuickTime Player will begin the conversion process, which you'll be able to monitor in the small pop-up window until it completes.

While this is a convenient method for converting video files, it may not be ideal if you're looking for a free solution or more features from your conversion software.

Can You Open AVI Files on a Mac?

The short answer is yes, it is possible to play AVI files on Mac computers. However, you will need to use specific third-party programs that are Apple-supported with the ability to play these files. Mac's default QuickTime Player won't be able to play these or other file formats that Apple doesn't support.

One of the best programs to use on your Mac to play AVI files is VLC. It's entirely free to download and install, and you don't need to worry about any malware or ads. In addition to AVI files, you can also use VLC to play DivX files on your Mac OS X. All you need to do is visit the VLC website to download the AVI player for your Mac and open your files. Otherwise, the best way to play AVI files is to convert them for your device using a converter.

Why Can't I Play AVI Files on My Mac?

If you are unable to play AVI files on your Mac computer, this is most likely to due incompatible codecs. Codecs are a part of the video player package included with programs such as QuickTime Player. Certain players include different codecs, based on what their developers support. QuickTime Player is an Apple product, which means that the video codecs included with this player are only Apple-supported codecs such as MP4. As such, AVI files aren't Apple-supported and aren't compatible with QuickTime Player or other Apple programs.

However, you can expand the code library of QuickTime Player by downloading the specific AVI codec required to play the file. If for any reason adding the codec isn't an option, you can also convert the AVI on your Mac to an Apple-supported format using a converter, or view the file on another third-party application that has the missing codec, such as VLC. Ultimately, if you want to play AVI files on your Mac, there are plenty of options available to help you play your favorite media.

It can be frustrating downloading your favorite media only to find that your Mac is unable to play it because it's in AVI format. The upside is that there's no shortage of helpful workarounds that make it easy to either convert the file or watch it as is. With programs such as Movavi Video Converter, VLC, or even the Mac's native QuickTime Player, you have ample tools available to help you convert and play AVI or other files that aren't ordinarily supported by Apple. Whether you prefer to download software or rely on web-based solutions, you don't have to look hard or very far to find the best way to watch AVI files.
