MTS vs M2TS / M2TS vs MTS: Differences between the HD camcorder AVCHD Formats

May I know the differences between .mts and .m2ts, the two extensions from the same camera file?

After shooting with my new Sony HDR-CX240 (1900x1080i), I imported the same file two ways. The former produced file with an mts extension and the latter produced .m2ts.modd & .m2ts.moff. When played with Windows Media player, the properties indicated the same thing. It said the codec applied was AVC/H.264 for both. Am I getting two true AVCHD files? What is the real difference between mts & mt2s if any? Which format is better for playback or editing and will make the best Blue Ray?

Best Answer:

M2TS: M2TS is a filename extension used for the BDAV MPEG-2 Transport Stream container file format, for multiplexing audio, video and other streams. This container format is commonly used for high definition video on AVCHD and Blu-ray Disc. In other word, M2TS refers to the stream packaging container for Blu-ray BDMV, the file extension of which is "m2ts" having a five-digit number. The BDAV container format (.m2ts) is a standard used on Blu-ray Discs. The M2TS files on a Blu-ray Disc are placed in the subdirectory "STREAM" of "BDMV" (or "BDAV") directory, which is at the root level.

MTS and M2TS in Common:

MTS and M2TS are both file extensions for AVCHD, the HD digital video camera recorder format, and both support 720p and 1080i HD video formats. They all play in great quality in 1080i direct on the PC or to a Sony TV using composite video or HDMI. MTS and M2TS files are all forms of MPEGs, Ted.

The Difference between MTS and M2TS

But they are lightly distinguishing. According to Wikipedia, HD cameras record mts but export as m2ts. The file extension of AVCHD video is "MTS" on camcorder that contains raw footage and will become "M2TS" if imported to computer. MTS is the format not collected by specific software, and will change into the video file with "m2ts" as the file extension after collection.

1.Supported Carriers:

MTS was developed by Sony and Panasonic together as the recording format for the HD camcorders of both, while M2TS was created to store movie data on Blu-ray discs.
In this respect: MTS vs M2TS = Camcorder vs Blu-ray

2. Supported Devices:

M2TS files can also be played on Sony PlayStation 3s (PS3), Sony Bravia TVs, Western Digital WDTVs, Xtreamer media player, Amkette FlashTV HD Media Player and Panasonic Viera TVs supporting playback of AVCHD.

3. Supported Software:

Both MTS and M2TS files can be accepted by Windows Media Player, VLC, 5KPlayer, as well as Apple's Final Cut Pro by using the AVCHD plugin in the Log and Transfer window. Daminion Media Management Software also allows importing and managing .MTS & M2TS files. If needing to play, watch or edit MTS or M2TS files on many more programs, one may have to seek to a MTS converter.
