If not, upgrade it. If your media player still doesn’t play AVI files, change the format of your video to a more popular one, for example, try to convert your AVI file to MP4.

Can I play AVI files on a Mac?

Yes, you can open some AVI files on a Mac using the default QuickTime Player. But keep in mind that this app doesn’t support some video and audio codecs that your AVI file may be encoded with. If you can’t open your video with QuickTime Player, try using another media player, like VLC.

Which format has better quality – MP4 or AVI?

MP4 and AVI are both container formats, so the quality of a video mostly depends on a video codec the file is encoded with. MP4 is the most widely used container for compressed videos since it’s supported by almost all devices and provides rather good quality while maintaining smaller file sizes. AVI is an older container format that’s supported by fewer media players and devices. Some video codecs used with AVI can result in higher quality, but the compression level will be rather low.

So if you want to play your videos on multiple devices or save hard drive space, we recommend you to change AVI to MP4. In case you plan to watch your videos on your computer only, AVI is a good choice.
