.M2T File Extension
What is an M2T file?
M2T is a high-definition video recording format used by older HD camcorders. It stores high-definition video data on DV and MiniDV tapes using MPEG-2 compression. Supported resolutions include 720p and 1080i.
The M2T format is sometimes referred to as "HDV." It was common in the early 2000s when HDV cameras were popular. However, the format is rarely used now since modern video cameras record to media cards rather than digital tapes.
How to open an M2T file
Several video programs, such as Adobe Premiere and MPlayer support M2T files. However, since the format has become increasingly rare, some programs that previously supported the HDV format may no longer open M2T files.
