MTS vs. M2TS: What’s the Difference Between MTS and M2TS?

While working with videos, you might have come across formats like MTS and M2TS. Even though both these formats seem pretty similar, they have a slight difference when it comes to their overall application. Therefore, if you also want to know the difference between MTS and M2TS, then you have come to the right place. Here, I will provide a detailed MTS vs. M2TS comparison from various perspectives and would also discuss a solution to repair corrupt MTS/M2TS files.

Part 1: An Overview of MTS and M2TS Formats

Before we learn the difference between MTS and M2TS formats, let’s quickly get to know about these media containers first.


MTS stands for MPEG Transport Stream and is a proprietary format that is managed by Blu-ray Disc Association. The format is used while recording HD videos in various camcorders (from brands like Sony, Samsung, and Panasonic).

It supports the recording of videos in up to 1080 HD resolution and uses a variable rate transport stream. The files are stored in MTS on camcorders with the AVCHD format, having one video and two audio encoding schemes.


M2TS (MPEG-2 Transport Stream) can be considered as a derived version of the MTS container that is used to store Blu-ray HD videos. Both the containers follow the same AVCHD format. For video compression, it relies on H.262 or SMPTE VC while for audio compression, it follows DTS, Dolby Digital, and Linear PCM encoding.

The major difference between both formats is that while MTS is used for recording videos, the file is changed to M2TS format when it is moved to a computer or a disc. Some of the major media players that support MTS and M2TS are VLC Media Player, SMPlayer, PotPlayer, All Player, MPlayer, and MTS Player.

Part 2: MTS vs. M2TS: What is the Major Difference Between MTS and M2TS?

Now when you know the basics, let’s do a detailed MTS vs. M2TS comparison based on different parameters.

Production and Handling

As I have listed above, both formats are managed by the Blu-ray Disc Association. The MTS format is implemented when you record your videos on camcorders from brands like Sony, Panasonic, or Samsung.

On the other hand, when the MTS files are transferred to a computer or are stored in a Blu-ray disc, they are automatically changed to M2TS formats. Therefore, while MTS is used for recording, M2TS is implemented for storing and distributing HD videos.

The difference between MTS and M2TS compression is negligible as both containers use the same technology powered by AVCHD. The audio compression technique can be uncompressed linear PCM, DTS, or Dolby Digital while MPEG-2, MPEG-4, or SMPTE is used for video compression.


There can be a slight difference between MTS and M2TS encryption techniques. Since the MTS format is implemented during recording, these videos are not encrypted. On the other hand, M2TS videos follow the typical Blue-ray encryption for copyright protection.

Carrier and Usage

Since MTS was created by Sony and Panasonic for recording, the format is mostly used in camcorder recordings only. M2TS is considered a more diverse format as it can be used for AVCHD as well as for BDAV transfer stream containers. This gives M2TS the accessibility to store Blu-ray disc videos as well as videos transferred from Sony or Panasonic camcorders.
