How to Open, Edit, & Convert M2TS Files

A file with the M2TS file extension is a Blu-ray BDAV Video file. BDAV is an abbreviation for Blu-ray Disc Audio-Video. M2TS stands for MPEG-2 Transport Stream.

BDAV is a standard for Blu-ray, but M2TS files are also often seen alongside MODD files from Sony camcorders.

Some BDAV MPEG-2 Transport Stream files may use the .MTS file extension instead.

How To Open an M2TS File

M2TS files can be opened with Windows Media Player, VLC, SMPlayer, 5KPlayer, and probably some other popular media player applications as well.

Sony's Picture Motion Browser Software should be able to open M2TS files too.

Note: If an M2TS player will not open the file, try changing the extension to MTS. Some software may only recognize the file if it uses the shorter extension, or vice versa.

As a standard, Blu-ray players should be able to play M2TS files natively. Select gaming consoles may support M2TS files as well, without having to convert the file first.

Note: The M2 file extension doesn't have anything to do with M2TS video files. M2 files are either World of Warcraft Model Object files used with the World of Warcraft game, or PC-98 Game Music files.

How To Convert an M2TS File

The best way to convert an M2TS file to MP4, MKV, MOV, AVI, etc., is with a free file converter tool. This list of Free Video Converter Programs and Online Services includes several programs that will convert M2TS files.

Tip: If the video converter you're using only supports, say, M2TS to MP4 conversion, but you want your video in the MKV format, just convert the M2TS to MP4 first and then use an MP4 converter to save the file to some other format like MKV.

For example, if you want to burn your M2TS file to a DVD, you can combine two programs. Use iWisoft Free Video Converter to save the M2TS to a format like MOV, and then open that MOV file in Freemake Video Converter to burn it to a DVD.

Convert Files is an online M2TS converter that can convert the file to MPEG, M4V, ASF, WMV, and other similar formats.

Note: Since Convert Files is a website, you have to upload the whole video online before you can convert it, and then you have to download it back to your computer. This process may take a while, so bigger M2TS videos are best converted using one of the converter tools from that list I mentioned above.
