Summary:
If you can’t play video files on Mac’s default media player (QuickTime), this article will provide you with alternative solutions to play your video irrespective of its codec.
There are dozens of video file formats used across the internet and more are being introduced all the time. Naturally, not every format is compatible with every media player. Considering this, it's extremely hard to set out common guidelines for playing different video files or codec on a particular OS, for example, Mac. But of course, that doesn’t mean we can’t have a basic framework in place.
Therefore, in this post, we've compiled a list of the most popular video file formats along with instructions on how to play them on your Mac. We'll keep adding more to this list in the future. If there are any formats that aren't on our list, do let us know in the comments below.
Why can’t QuickTime play certain file formats?
Like other media players, QuickTime evaluates both audio and video codecs within a file when you try to play it. The player won’t play the file if there’s an issue with any codec or if its header information is damaged. For instance, when trying to play AVI files in QuickTime, the player fails to identify the video's Cinepak and ALaw 2:1 codec, and hence is unable to play AVI videos.
To overcome these issues with other file formats we have come up with different alternatives to QuickTime player in the section below.
Key Solutions to Play Video Files or Codec on Mac:
Here’s how you can play different files on Mac systems using different media players.
1. AVI
Audio Video Interleave, or AVI, is a multimedia container format developed by Microsoft as part of its “Video for Windows” technology in November 1992. AVI files can hold both audio and video data in a single file container, allowing for simultaneous audio and video playing.

2. MKV
A file with the MKV extension is often referred to as a Matroska Video file. It's a video container similar to MOV and AVI, except it can hold an infinite amount of audio, video, and subtitle tracks (like SRT or USF). MKV is frequently used as the carrier for sharing high-definition videos online, as it supports descriptions, ratings, and cover art.

Alternatively, you can also try playing it with VLC. Refer to the steps from the previous solution to download VLC for Mac and play the MKV file with it.
There are other alternative media players as well, such as MKPlayer, developed especially for playing MKV files on Mac. You can download the latest version of MKPlayer from the Apple app store.

4. MP4 and MPEG
Moving Picture Experts Group (MPEG) developed the MP4 standard format, which is widely used for transferring video files over the Internet. MP4 is a type of MPEG file format used for video encoding. The capacity to store subtitles, still photos, and other data alongside digital video and audio sets MP4 apart from other MPEG formats.
How to play MP4 and MPEG files on Mac?
Although QuickTime supports a wide range of music and video formats, some MP4 videos may not be recognized by the application. This is usually due to the fact that your MP4 video may be encoded with an older or specialized codec that QuickTime can’t recognize.

4. GIF
A GIF (pronounced "gif") is simply an image file with animation. GIFs aren't truly videos, so we call them "animated images." They're more akin to flipbooks than anything else.

A GIF, or Graphics Interchange Format file, is a basic video with only a few frames that is often used on blogs or memes for looping animations. When you double-click a GIF on a Mac, it defaults to Preview, which displays the individual frames rather than animating them.
