M2TS File

M2TS File

An M2TS file, short for MPEG-2 Transport Stream, is a type of video file format used primarily for storing high-definition video on Blu-ray discs, AVCHD, and some models of digital camcorders. This file format supports both 720p and 1080i formats, making it a go-to choice for preserving the quality of HD video content. M2TS files are known for their ability to encapsulate large amounts of data, including video, audio, and additional features like subtitles and menus, all within a single file. This is achieved by utilizing a container format, which allows various data streams to be multiplexed together, ensuring synchronized high-definition video and audio playback.
