What is MTS

Peter Rugg Updated on Apr 15, 2022 4:22 PM

MTS is a newly emerging file format for multiplexed audio, video and other streams. The video recorded by Sony is often accepted mts as its video format, which uses H.264 as video encoding and AC-3 as audio encoding with video of full HD or resolution of 1440 × 1080. Among others, the resolution of 1920 × 1080 has come up to the standard, which represents an excellent visual quality. As a production of high definition, mts is most commonly used in storing video of Sony HD camera and cameras of other brands. The extension name of video recorded from Sony camera or others is defaulted to use mts, while changes to m2ts after the original video exporting to other handsets.

Since MTS is a complex container format using H.264 for encoding, it has a highly demand on the compatibility of hardware. Unlike other conventional formats like AVI, which can be smoothly played on any computer, MTS may not be accepted by computer if the machine performed poorly. Besides, the video volume of MTS is rather larger than other formats for it retains high definition video quality. Consequently, the video recorded from digital camera will be converted into other formats (see how to convert .mts to .mov on a Mac) for reducing its bulky size. In addition, it will also be transferred into DVD format when we need to play on the DVD player.

About format conversion

There are two alternative ways to convert MTS file into AVI or MPEG:

1. Convert the original .mts to .avi or .mp4 directly, then it will be available to play in any player.

2. Install a plug-in that supports format conversion, whether .mts to .avi or vice versa.


Advanced Video Coding High Definition(AVCHD) is a format developed by Sony along with Panasonic for digital recording and playback of high definition video. The AVCHD is based on MPEG-4 AVC/H.264 for encoding standard and supports 480i, 720p, 1080i, 1080p, Dolby AC-3 (Dolby Digital) and uncompressed linear PCM audio as well as stereo and multichannel surround (5.1).

AVCHD uses a 8cm mini-DVD disc to store a twenty minutes high definition video. In the future, it may be updated to use double sided disc for storing a video that more than 60 minutes. However, a mini-DVD disc normally can only store a thirty minutes video with 480i.

In a wave of widely used HDTV, users of domestic camera are ever-increasing. And the camera also be disposed to improve its performance. That is how AVCHD came into being. AVCHD adopts the MPEG-4 AVC/H.264 standard, supporting a variety of standard, high definition, and stereoscopic (3D) video resolutions while H.264 is most frequently used in Blu-ray Disc. Thanks to its self independent in making video with AVCHD format, AVCHD successfully avoided some copyright issues.


AVCHD format makes it possible for some products of HD camera manufacturers to be compatible with all 8cm DVD formats, including DVD-RAM, DVD-R, DVD-RW, DVD+RW and DVD+R. You can refer to a detailed instruction on burning MTS to a DVD for playback on big TV Yet AVCHD disc is unacceptable by DVD player. If users want to watch video from AVCHD camera, migrating video from camera is an indispensible step to make it available for playing.

About .m2ts

M2TS is a container format supported multiplexing audio, video and other streams. It is based on the MPEG-2 transport stream container. This format is most commonly used for HD video Blu-ray Disc and AVCHD.

The major difference between MTS and M2TS:

The video recorded from DV is often used .mts as its filename extension. However, after transferring video to personal computer or other devices, the video filename extension becomes .m2ts.

With this optimal compression, the visual quality of m2ts is much more higher than the HD format.

Format conversion

1. Convert M2TS into HD AVI directly. This method is applied to DV user, making it available to edit the video over and over again.

2. Convert M2TS into HD MPEG2(M2T).

3. Use software like Vegas 8.0, Premiere CS 4.0 or eduis 5.0 to re-edit.

4. Convert HD M2TS into MPEG2. This method is a less recommended one for the original video recorded form the camera is good enough to be transferred to M2TS format.
