How to Convert M2TS to MP4 on Mac/Windows/iPhone/Android

M2TS or MPEG-2 Transport Stream was created to store 1080i and 720p high-definition video files on AVCHD, HD camcorder, Blu-ray discs, hard-drives, or more. Compared with MP4, it's larger in size and slightly less compatible. If you desire to convert M2TS to MP4, this post shows how to do it on desktop and mobile.

 

M2TS file origin

Typically, there are two main sources: AVCHD camcorders and Blu-ray discs.

Most HD camcorders contain .mts files. When you directly drag-and-drop them from the camcorder to your computer, the file suffix is .mts. If files are imported using, for instance, PlayMemories Home™, its suffix becomes .m2ts. Some M2TS files are renamed from MTS because there is not much difference between the two.

Similar to VOB files stored in a standard DVD VIDEO_TS folder, M2TS in a Blu-ray disc BDMV or BDAV folder are used to provide multimedia content like video, audio, and subtitle.
