Part 3. The introduction to the M2TS format

M2TS stands for MPEG-2 Transport Stream. Blu-ray discs use the M2TS format, and the files are huge in size. In fact, M2TS is a container that consists of H.262, , or SMPTE VC-1 video information, and Dolby Digital, DTS, or Linear PCM audio information. Depending on the type of video and audio information that an M2TS video file contains, its size may vary significantly.

How to open M2TS videos?

Usually, the Blu-ray discs hold the M2TS movies, and they can be played on any Blu-ray device. In case the M2TS files are on your PC, you can use any advanced and codec-equipped software program such as a VLC media player to watch the videos. Furthermore, if you are using Wondershare UniConverter, it has its own Previewer that can be switched to full-screen mode while previewing an imported M2TS video, thus using the app as a full-fledged M2TS player.

What is the difference between MTS and M2TS?

When you record video footage from an advanced camcorder such as Sony, Canon, etc., the stored files in the memory are in MTS format. When these files are exported to a computer, they are automatically converted to M2TS to make them universally compatible and readable by the operating system and/or the applications that attempt to play the videos that they contain.


An M2TS video is not hard to convert to any relevant format as long as you have an efficient and robust application such as Wondershare UniConverter installed on your PC. However, if your frequency of conversion is not too high, you can always go for a web portal that could get the job done for you for free and without using your PC’s hardware resources, but with certain restrictions such as file size limit, watermarks, delays in uploads and downloads, etc.

* Some of the above codec formats may need to be supported by system.
