Right audio/ video codecs are essential to play a video file in any media player. In the absence of codecs, the video may throw error like ‘video file cannot be played’ or ‘codec is required to play this file’.

So download the codec for your video file type. If you are not sure which codec to download, try a codec pack like K-Lite available for macOS. It contains codecs for almost all commonly used video file formats.

5. Convert the video file format

Not every media player supports all video file types. Thus, when you try to play an unsupported file type, the video won’t open and give error. For example, MKV or MTS files won’t open in QuickTime as it doesn’t support these formats. While iMovie can only open 3GP, AVI, M4V, MOV, and MP4 videos. Hence, if a video is showing an unsupported codec or file type error, try to open it by changing the file format.

Preferably, change the video format to a widely supported file type, such as MOV and MP4. Use any online video converter, Stellar Converter for Audio Video or VLC Media Player. If the video problem on Mac is due to a file format or codec issue, it would resolve with this method.
