Typical use: Converting M2TS to MP4 makes camcorder and Blu-ray footage playable and shareable everywhere.
About the M2TS format
M2TS is the transport stream of Blu-ray discs and AVCHD camcorders: MPEG-2 or H.264 video in fixed 188-byte packets, built for broadcast-style resilience rather than compactness. Copy a camcorder's clips off its card and you are holding M2TS files; so is most of a decrypted Blu-ray folder structure.
The format plays in VLC and a handful of editors, but phones, social platforms and web apps reject it. Converting to MP4 is the standard hand-off: the video re-encodes to H.264 at your chosen quality and the result plays literally everywhere.
