Have you encountered a problem with a M2TS file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a M2TS file here. In the further part of this page we have added a list of programs that should open your M2TS file. It is enough you choose a proper application for your operating system, download and install it.


The file extension M2TS indicates a file containing data according to the BDAV standard. This can be both video and audio.

The format is mainly used on BluRay discs. It was partially designed to be compatible with the AVCHD standard. AVCHD files, which are still on the storage medium of the recording device (eg camcorder) are usually the extension mts. After importing to the computer, however, the extension M2TS is often used as well.

The files include a transport stream in an MPEG-2 TS based container, video data with a resolution between 720x480 (SD) and 1920x1080 (FullHD) and audio data as PCM (Pulse Code Modulation), AC3 or TrueHD (Dolby Digital) or DTS or DTS-HD (Digital Theater System). In addition, other data streams or multiple video streams may be included. For the compression of the video data usually MPEG 2, VC1 or H.264 is used.

On BluRays, the M2TS files are protected by a digital rights management (DRM) method, usually AACS encrypted.

How to open a M2TS file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the M2TS file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a M2TS file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support M2TS files. At this point we are looking for disk space where the application was installed in and we can link it with a M2TS file. Since then, our operating system will use the selected program to support all M2TS files.

Other issues

Despite the described problem with M2TS there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the M2TS file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the M2TS file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
