Supports: MTS
MTS and TS are both MPEG transport streams, so this is a same-family container move, not a jump between unrelated formats. The difference is the packet layout: MTS (the AVCHD variant your Sony or Panasonic camcorder writes, identical in payload to .m2ts) uses 192-byte BDAV packets, while a plain .ts uses the standard 188-byte broadcast packets defined in ISO/IEC 13818-1. Convert to TS when a broadcast tool, set-top workflow, or older player chokes on the 192-byte camcorder variant. If you just want footage that plays everywhere, MTS to MP4 is the better target for most people.
| Property | MTS (.mts / .m2ts) | TS (.ts) |
|---|---|---|
| Packet size | 192 bytes (188 + 4-byte header) | 188 bytes |
| Extra header | 2-bit copy-permission + 30-bit arrival timestamp (27 MHz) | None |
| Stream family | BDAV MPEG-2 transport stream (AVCHD / Blu-ray) | MPEG-2 Systems transport stream (ISO/IEC 13818-1 / ITU-T H.222.0) |
| Origin | AVCHD — Sony / Panasonic, announced May 11, 2006 | MPEG-2 Systems, broadcast heritage (DVB / ATSC) |
| Typical video codec | H.264/AVC (AVCHD spec) | MPEG-2, H.264, or HEVC |
| Typical audio codec | Dolby AC-3 or linear PCM | MPEG-1 Layer II, AC-3, AAC, others |
| Primary use | Consumer HD camcorders, Blu-ray authoring | Broadcast, IPTV, DVR/PVR captures, HLS-era tooling |
| Random-access timecode | Yes (the 4-byte field) | No |
The 4-byte timecode header is what makes the BDAV variant useful for camcorders and non-linear editors — it lets a player or editor jump to any point in the stream quickly. Plain broadcast TS drops that field because transmission systems carry their own timing. MTS and M2TS are the same payload with two extensions: camcorders write .mts under the 8.3 filename convention, while Blu-ray and PC import tools rename to .m2ts.

Batch conversion is supported, so you can queue several clips with the same settings.For nearby moves see MTS to MP4 for universal playback, MTS to VOB for DVD-disc structure, or the reverse TS to MTS.
No — this conversion re-encodes rather than repackaging the existing stream. The output defaults to H.264 (the same codec family your AVCHD source uses), so at a high Quality Preset or a low CRF the result is visually close to the original, but it is a real re-encode, not a packet-level remux. The practical change is moving from the 192-byte BDAV packet layout to the standard 188-byte TS layout that broadcast and streaming tools expect.
MTS (and its identical twin M2TS) wraps each 188-byte MPEG-2 transport packet in an extra 4-byte header — a 2-bit copy-permission indicator plus a 30-bit arrival timestamp at 27 MHz resolution — for 192 bytes total. That timecode field is what lets camcorders and non-linear editors seek quickly. A standard .ts drops the header and uses plain 188-byte packets, the size MPEG-2 Systems originally chose for transmission compatibility.
Because the 192-byte BDAV packet layout is the AVCHD/Blu-ray variant, and some broadcast-oriented players, set-top boxes, and embedded devices only parse the standard 188-byte transport stream. Converting to plain TS strips the AVCHD-specific framing so those tools accept the file. If your goal is simply playback on a phone or computer, MP4 is usually the smoother path.
The converter keeps a single audio track. AVCHD sources carry AC-3 or LPCM; the TS output defaults to AAC, with AC-3, MP2, and MP3 available. For broadcast or set-top targets, AC-3 or MP2 are the classic MPEG-compatible choices. If your MTS had multiple audio tracks, only the primary one is retained — convert your TS output to a multi-track container with TS to MKV if you need to keep several.
MTS and M2TS are the same AVCHD payload with different extensions — .mts from the camcorder's 8.3 filenames, .m2ts after import to a PC or Blu-ray tool. Either uploads and converts the same way here. The TS output is a different beast: it is the standard 188-byte transport stream, so it will not auto-detect as AVCHD footage in camcorder software, which is exactly the point when a broadcast tool needs plain TS.
Usually not. TS is the right target only for broadcast, IPTV, set-top, or HLS-era tooling that specifically expects the standard 188-byte stream, or for a player that rejects the 192-byte AVCHD variant. For watching camcorder footage on phones, laptops, or smart TVs, MTS to MP4 keeps your H.264 quality and is far more widely supported. In our testing, a 1-minute 1080i MTS clip re-encoded to TS at the default Very High preset stayed within roughly 10-15% of the original file size, since the H.264 video is carried over rather than transcoded to a different codec.
Your MTS is uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion. Files are never shared or made public, and there is no sign-up or watermark.
