M2TS (MPEG-2 Transport Stream) is the container format for Blu-ray discs and AVCHD camcorders, carrying H.264 or H.265 video at 17-50 Mbps with AC3, DTS, or LPCM audio across 192-byte transport packets with timing synchronization bytes. MP4 (MPEG-4 Part 14) is the universal video container that plays on every modern device, browser, and platform. Converting M2TS to MP4 is the single most important conversion for making Blu-ray and camcorder content universally accessible.
M2TS is designed for disc-based sequential playback and broadcast, not for general computing. Most computers, phones, tablets, and web browsers cannot play M2TS files natively. MP4 is the universal standard — it plays in Chrome, Firefox, Safari, Edge, VLC, on iPhone, Android, Windows, Mac, Linux, smart TVs, and uploads to every video platform (YouTube, TikTok, Instagram, Vimeo). Converting M2TS to MP4 transforms specialized disc/camera format into universally playable content.
Since M2TS typically contains H.264 video and MP4 natively supports H.264, the video stream can often be remuxed (stream copied) without re-encoding — zero quality loss. Audio requires transcoding from AC3/DTS to AAC (MP4's standard audio codec) unless the M2TS contains AAC already. The transport stream's 192-byte packets and timing bytes are stripped in favor of MP4's random-access box structure. The moov atom is placed at the file start (faststart) for progressive web playback. If the M2TS contains H.265/HEVC, that can also be remuxed into MP4 for devices that support HEVC.
When stream copying H.264 video, quality is bit-identical to the source — zero loss. Audio transcoding from AC3 at 640 kbps to AAC at 256 kbps is perceptually transparent. The only scenario requiring video re-encoding is if you want to change resolution, codec, or bitrate. In the default remux mode, the conversion is fast and perfectly preserves the original Blu-ray or camcorder quality.

M2TS to MP4 is the essential conversion for Blu-ray and camcorder owners. It unlocks universal playback while preserving the original high-definition quality through stream copying. This should be the first conversion you perform on any M2TS file.
