What is a M2TS file?
A .M2TS file is a High-definition video transport stream. The Blu-ray Disc Association and Sony use this format to store multiplexed audio, video, and other streams. You will often see a .M2TS file described as a Blu-ray BDAV Video File. It is the standard format for high-definition video on Blu-ray discs and AVCHD camcorders.
How to open M2TS files?
You can open and play .M2TS files using popular third-party media players like VLC media player. For advanced users and developers, command-line tools like FFmpeg can read, convert, and stream these files. Standard video players built into Windows and macOS often lack the required codecs to play a .M2TS file directly.
File conversion and best practices
Because .M2TS files are large and sometimes difficult to share, many users choose to convert them. You can convert a .M2TS file to a more widely compatible format, such as .MP4 or .MKV, using convert.guru. This makes the video much easier to play on smartphones, web browsers, and smart TVs.
