OGV to MTS Converter

Convert OGV to MTS: What This Tutorial Covers

This walks you through turning an old .ogv (Ogg video, usually Theora + Vorbis from the open-web era) into an .mts file — the AVCHD transport stream that camcorder-oriented editors like older Sony Vegas, PowerDirector, and AVCHD-aware timelines expect. MTS is a niche target: if you only need a clip that plays and edits everywhere, convert OGV to MP4 instead. Reach for MTS specifically when an AVCHD editing project or a transport-stream workflow demands it.

How to Convert OGV to MTS

1. Upload Your OGV File: Drag and drop your .ogv onto the box, or click "+ Add Files" to pick it from your computer. You can queue several clips and convert them with the same settings.
2. Set the Video Codec: Open "Show All Options" and leave the Video codec on H.264 — that is the codec AVCHD/MTS is built around, so it keeps your output a valid transport stream.
3. Match the Audio and Resolution (Optional): Under Audio codec choose AC-3 (Dolby Digital) for the most AVCHD-faithful result, or AAC if your editor accepts it; leave Video resolution on "Keep original" so a small SD-era clip is not stretched.
4. Convert and Download: Click "Convert" and download your .mts. No sign-up, no watermark.

Walk-through: Picking the Right Codecs for MTS

MTS is not really a video codec — it is an AVCHD-flavored MPEG-2 transport stream that carries H.264 video and Dolby Digital (AC-3) or linear PCM audio. That constraint drives every option that matters here:

• If you want maximum compatibility with an AVCHD editor, set Video codec to H.264 and Audio codec to AC-3. This is the combination real camcorders write, so AVCHD-aware software treats the file as native footage.
• If your editor is fussy about audio, AAC inside the stream usually still imports; AC-3 is the safer default when you are unsure.
• If the source is a small, standard-definition Theora clip (common for 2005–2012 web video), keep the resolution on "Keep original." Upscaling to 1080p only inflates the file — it cannot invent detail that the Theora encode never captured.
• If file size matters more than fidelity, the Quality Preset and bitrate controls let you cap the output, though MTS streams are inherently larger than an equivalent MP4.

One honesty note on quality: Theora is a lossy codec, so an .ogv has already discarded detail. Re-encoding to H.264 is a second lossy pass — it cannot restore anything Theora threw away, and a slightly softer result is normal. There is no setting that recovers the original sharpness.

Common Errors and How to Fix Them

• "My editor still won't import the MTS" — Some consumer NLEs only recognize AVCHD when the full BDMV/STREAM folder structure is present, not a bare .mts. Try placing the file in a STREAM folder, or convert to MP4, which virtually every editor reads directly.
• "The audio is missing or silent" — The source .ogv may carry Vorbis audio your player can't decode in an MTS wrapper. Re-run the conversion with Audio codec set to AC-3 so the audio is re-encoded into an AVCHD-native track.
• "The video looks soft or blocky" — That detail loss came from the original Theora encode and the second lossy pass; it is not a bug in the conversion. Starting from a higher-quality source is the only real fix.
• "The output file is huge" — Transport streams add overhead and H.264 at high bitrate is heavy. Lower the Quality Preset or set a target bitrate, or switch to MP4 if you don't strictly need MTS.

When This Doesn't Work

If your .ogv is corrupted, partially downloaded, or carries an unusual codec (some Ogg files wrap VP8 or Dirac rather than Theora), the conversion may fail or drop a stream. In that case, first confirm the file plays end-to-end in VLC. For most modern uses — sharing, web embedding, or editing in current software — MTS is the wrong destination: convert OGV to MP4 for universal playback, or convert OGV to WebM to keep the clip in the open, royalty-free family it started in. Going the other way, convert MTS to OGV handles AVCHD footage you want in an open container.

Frequently Asked Questions

Why would I convert OGV to MTS instead of MP4?

For most people, you wouldn't — MP4 is smaller, plays everywhere, and imports into nearly every editor, so OGV to MP4 is the better default. MTS makes sense only when you are feeding an AVCHD-based editing project or a transport-stream workflow that specifically expects .mts files, which is mostly older camcorder-oriented software.

Will converting OGV to MTS improve the video quality?

No. The .ogv was encoded with Theora, a lossy codec, so detail is already gone, and re-encoding to H.264 inside MTS is a second lossy step. In our testing, a 480p Theora clip converted to MTS looked marginally softer, never sharper — there is no upscale or enhancement that recovers what the original encode discarded.

What codecs end up inside the MTS file?

MTS is an AVCHD-style MPEG-2 transport stream that carries H.264/AVC video with Dolby Digital (AC-3) or linear PCM audio. We keep the video on H.264 by default because that is the codec AVCHD is built around; choosing anything else would produce a stream most AVCHD software wouldn't accept as native footage.

Can my Vorbis audio survive the conversion?

Not directly — AVCHD/MTS doesn't carry Vorbis, so the audio is re-encoded. Pick AC-3 for the most camcorder-faithful track, or AAC if your editor prefers it. Because Vorbis is lossy, re-encoding the audio is also a lossy pass, though the difference is usually inaudible for spoken-word or web-quality clips.

My browser stopped playing OGV files — is that related?

It is. Chrome removed the Theora video codec in version 123 (March 2024), and Firefox followed, so many .ogv clips no longer play natively in modern browsers — only the Ogg container support and Theora itself were dropped, not Ogg audio. Converting to MTS (or, more practically, MP4) is one way to get those old clips playing and editing again.

What happens to my file after I convert it?

Your OGV is uploaded over an encrypted connection, processed on our servers, and the files are deleted automatically a few hours after conversion. There is no sign-up, no watermark, and your files are never shared or made public.
