Next, you will be introduced to more information about how to play MKV files with QuickTime.

Part 1: Can QuickTime Play MKV Files

One of the key questions some users may be facing is whether QuickTime can play MKV files or not. There are a lot of video formats in the digital world. Things can be easier if you rip or download a common video file format which can be compatible with the current digital media players. However, sometimes, you may be stuck with some videos or fantastic Hollywood movies ended with some uncommon extensions, for example, MKV, in such a case, you may find it is not able to play or open MKV files with the current media players, like QuickTime. Well, what is MKV file actually? MKV (Matroska Multimedia Container) is an open standard free container and file format. It is a multimedia package format that can accommodate an unlimited number of video, audio, picture or subtitle tracks in a single file. So, it’s not a compressed format, but a multimedia container file defined by Matroska. The goal is to preserve common multimedia content such as movies and TV shows as a unified format.

Therefore, officially speaking, QuickTime doesn’t support MKV files directly. In other words, when you are trying to play or open MKV files with QuickTime on your Mac, you would receive a pop-up message saying that "Error – 2018: the file is not a movie file" or something like that. So, if you are wishing for the QuickTime to offer you the direct solution for the MKV playback, you may be disappointed. In order to play MKV files successfully, you need to figure out other methods.
