The question is, what to do with these M2TS files now? Below is further information on what you can do and how to use them. How to Open an M2TS File M2TS files can be opened with Windows Media Player, VLC, SMPlayer, 5KPlayer, Splash, and other popular media player applications. The Sony Picture Motion Browser Software should be able to open M2TS files, too. All of those M2TS players are available for Windows, but VLC also works for playing M2TS videos on Linux and macOS. If an M2TS player doesn't open the file, change the extension to MTS. Some software may only recognize the file if it uses the shorter extension or vice versa. To do this, open the File or Windows Explorer Options window, and in View, clear the Hide extensions for known file types check box so that you can see and edit the file extension. 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. How to Convert an M2TS File The best way to convert an M2TS file to MP4, MKV, MOV, AVI, and other formats, is with a free file converter tool. This list of Free Video Converter Programs and Online Services includes several programs that convert M2TS files. If the video converter you use supports only M2TS to MP4 conversion, for example, but you want the video in MKV format, convert the M2TS to MP4, then use an MP4 converter to save the file to another format like MKV. For example, if you want to burn an M2TS file to a DVD, combine two programs. Use iWisoft Free Video Converter to save the M2TS to a format like MOV, then open the MOV file in Freemake Video Converter to burn it to a DVD. Convert Files is an online M2TS converter that converts files to MPEG, M4V, ASF, WMV, and similar formats. Since Convert Files is a website, you must upload the video online before you can convert it, then you can download it to your computer. This process may take a while, so bigger M2TS videos are best converted using an offline converter tool. Still Can't Open the File? Some file extensions look like they read M2TS when they're really a little different. Even if they're spelled similarly, though, the formats might not be related, and that's probably why you can't open the file with one of the M2TS players above. For example, 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. Neither are related to M2TS files and therefore don't open with the programs mentioned above. M2T files are very close in spelling to M2TS files and are video files, in the HDV Video file format. However, M2T files are commonly used as the HD video recording format for cameras, not Blu-rays. If your M2TS file doesn't open with the programs from above, double-check the file extension to ensure that it says .M2TS. If it doesn't, research the file extension you see to learn more about the format and which programs are able to open it.
