M2T file extension
High-definition Video File
The .M2T format is a high-definition file, more commonly known as "HDV". These files are created by various high-definition video camcorders.
The format was originally developed by JVC and swiftly supported by Sony, Canon and Sharp camcorders, using MiniDV/DVC cassettes.
This file type uses MPEG-2 compression and allows for resolutions of 720p and 1080i.
HDV is backwards compatible with DV.
My main concern is why does it record with this kind of extension rather than .MPEG2!
