The formats listed above are the ones that the QuickTime player accepts without giving any error message or the need for conversion. This means that if you want to play a video or audio format that is not listed as above, you will have to use an alternative player that supports the file or you will need to convert the format of that file to one of the formats listed above.

Since QuickTime player does not support a lot of formats, users normally have an alternative player on their computer at all times that supports more formats than the QuickTime player. However, there are decoders that can be installed on the QuickTime player that will enable playing of the non-compatible formats as well. Every decoder has a list of formats it supports so you should know the formats a decoder accepts before downloading it of course.

Part 2. What are QuickTime non-compatible formats?

As the name suggests, these are the media formats that are not compatible with the QuickTime player. No matter how hard you try to play any of the non-compatible formats with QuickTime, it won’t work and you will get an error message such as in the picture given below.

To play any of the QuickTime non-compatible formats, you need to use a media player that supports them. There are only a few media players out there that support unlimited number of formats, for example, the VLC Media Player. However, if you prefer using QuickTime only instead, you can always convert the non-compatible formats using a video converter such as the Wondershare Video Converter Ultimate in to a suitable QuickTime compatible format at first.
