OGV to MTS Converter

OGV to MTS Converter

.ogv is Xiph.Org's Ogg video profile — the extension RFC 5334 assigns to video/ogg, normally carrying Theora video and Vorbis audio. .mts is the opposite kind of file: the extension consumer AVCHD camcorders from Sony, Panasonic and Canon write onto their memory cards, holding H.264 video inside an MPEG-2 transport stream.

This is a niche conversion and it is worth being precise about what you get, because "MTS" means two slightly different things. This page produces a transport stream with the right codecs under the .mts name — which is what most editors and players want when they ask for MTS. It does not produce a byte-level replica of a camcorder card, and the section below spells out exactly where the two differ. If what you actually need is a clip that plays and edits everywhere, OGV to MP4 is the better page.

MTS and AVCHD at a Glance

What This Converter Actually Writes

Being honest about this matters more on .mts than on almost any other target, because the extension implies a disc-and-card format rather than just a codec pairing.

The practical takeaway: leave the video codec on H.264 and switch the audio codec to AC-3 if the file is going into an AVCHD-aware editor. That gets you the codec pairing the AVCHD specification actually names. The framing and folder structure are not something a file converter can reproduce.

How to Convert OGV to MTS

1. Upload Your OGV File: Drag the .ogv onto the page or click "Add Files" to browse. Several clips can be queued and converted on identical settings.
2. Keep the Video Codec on H.264 and Set Audio to AC3: Advanced Options opens on H.264 video with AAC audio. H.264 is the only codec AVCHD permits, so leave it; switching Audio Codec from AAC to AC3 matches the spec and is the safer bet for camcorder-oriented software.
3. Set Quality and Resolution, and Watch the Trim Duration: File Compression opens on Quality Preset at "Very High (Recommended)". Video resolution opens on "Keep original", which is what you want for an SD-era Theora clip. If you switch Trim to "Time Range", its Duration field is pre-filled at 10 seconds — change it or you will get a ten-second file.
4. Convert and Download: Click Convert and save the .mts. No sign-up, no watermark.

Frequently Asked Questions

Is the .mts this produces the same as a file from my camcorder?

The codecs can be, but the framing is not. AVCHD stores video in BDAV source packets — 192 bytes each, made of a 4-byte arrival-timestamp header in front of a standard 188-byte MPEG-2 transport packet. Our output is a plain MPEG-2 transport stream with bare 188-byte packets under the .mts name. Every general-purpose player and most editors read it happily; software that specifically validates AVCHD framing may not treat it as native camcorder footage.

Which audio codec should I choose for AVCHD compatibility?

AC-3. The AVCHD specification allows exactly two audio codecs, Dolby Digital (AC-3) and Linear PCM, and of those only AC-3 is offered here. The page defaults to AAC, which plays fine in general-purpose software but is not part of the AVCHD audio set — so if the file is destined for an AVCHD-aware editor, change it before converting.

Why does my editor still refuse to import the file?

Usually because it is looking for the AVCHD folder structure rather than a loose file. Real camcorder media puts clips inside a BDMV/STREAM directory tree with matching clip-information files, and some consumer NLEs will only mount AVCHD that way. Two workarounds: drop the .mts into a STREAM folder and point the editor at the parent, or sidestep the format entirely with OGV to MP4, which essentially every editor imports directly.

Is there any difference between .mts and .m2ts?

Sony's own support material states there is really no functional difference and that either extension can be renamed to the other. In camcorder practice .mts is what gets written to the card and .m2ts is what appears once the footage is imported to a computer or authored to disc. One genuine difference on our side: because FFmpeg infers BDAV framing from the output filename, OGV to M2TS produces 192-byte source packets while this page produces plain 188-byte ones.

Can I keep MPEG-2 video instead of H.264?

MPEG-2 is in the Video Codec dropdown and a transport stream carries it perfectly well — that is how broadcast television is delivered. What you lose is the AVCHD claim: AVCHD defines exactly one video codec, H.264, so an MPEG-2 stream in a .mts file is simply a transport stream with a misleading extension. Choose it only if a specific piece of broadcast-oriented software asked for MPEG-2.

Will converting from OGV improve the picture?

No. Theora is lossy, so the .ogv has already discarded detail permanently, and our server re-encodes rather than stream-copying — that is a second lossy generation. A high preset keeps the result close to the source; nothing here can rebuild what the original encode threw away. Leaving Video resolution on "Keep original" also avoids upscaling an SD-era clip into a bigger file with no extra detail in it.

Does the Vorbis soundtrack survive?

Not as Vorbis — transport streams do not carry it. The audio is decoded and re-encoded, to AAC by default or AC-3 if you select it. That is a second lossy pass on already-lossy audio, generally inaudible on speech and web-quality music. There is no lossless audio option on this page, so if the soundtrack matters more than the AVCHD framing, OGV to MKV offers FLAC.

Why is my .mts so much larger than the original .ogv?

Transport streams add per-packet overhead, and H.264 at a high preset will comfortably exceed the bitrate of a modest Theora encode. Drop the Quality Preset a step, or switch File Compression to "Specific file size" and name the number you want. If size is the real priority and the transport stream is not, MP4 with the same H.264 payload will be noticeably smaller.

What happens to my files after the conversion?

Your .ogv is uploaded over an encrypted connection, decoded and re-encoded on our servers, and both the upload and the finished .mts are deleted automatically after a few hours. There is no sign-up, no watermark, and files are never shared or made public. Going the other way, MTS to OGV takes camcorder footage back into the open Ogg family.
