Fast, secure MTS to OGV conversion. No registration required.
Setup: MTS is the AVCHD camcorder variant of the MPEG transport stream. Goal: an interchangeable OGV. A MTS to OGV conversion makes a recording portable. Video containers matter more than you might expect: players that handle OGV natively sometimes stutter or flat-out reject MTS with the same codec inside. Uploading above triggers a stream-level rewrap when possible, keeping the visible quality identical to the source. Context: MTS is the AVCHD camcorder variant of the MPEG transport stream. OGV is the video profile of the OGG container, typically wrapping Theora or VP8.
AVCHD Video
Source formatMTS (AVCHD) is a high-definition video format from Sony and Panasonic camcorders.
OGV Video
Target formatOGV (Ogg Video) is an open video format using Theora codec in an Ogg container.
Why convert MTS to OGV
Sending MTS to someone on a non-matching operating system frequently leads to "file cannot be opened". OGV avoids that by sitting in the middle of everyone's compatibility list. The repackage runs quickly and without generational loss when codecs already align.
HOW TO CONVERT
MTS → OGV
Drop the video file
Select a MTS file. We read the container and stream descriptors to plan the conversion.
FFmpeg handles the repackage
When codecs align, FFmpeg rewraps the existing streams into a OGV container — no quality loss, near-instant finish.
Retrieve the OGV
The OGV download is ready in seconds for stream-copy jobs, minutes for full transcodes.
Common Use Cases
Share across platforms
Send OGV files to anyone without worrying about whether they have the right software for MTS.
Embed in documents
Drop OGV output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
OGV often produces smaller files than MTS for web, email and storage.
Archive & future-proof
Store in a widely-supported format that will still open on future operating systems without legacy plugins.
MTS vs OGV — Strengths and limitations
What each format does best, and where it falls short.
MTS Strengths
- Native format for every AVCHD camcorder since 2006.
- H.264 compression — small files for high-def quality.
- Direct compatibility with iMovie, Premiere, Resolve, Final Cut.
- Carries Dolby Digital 5.1 audio on flagship camcorders.
Limitations
- Slow to decode — editors typically transcode for editing.
- Proprietary folder-structure conventions complicate direct import.
- Largely legacy as smartphones replaced dedicated camcorders.
OGV Strengths
- Patent-free codec (Theora) and container (Ogg).
- Mandatory for Wikipedia uploads — preserves public-domain video.
- Good for small educational clips.
- Open-source reference implementations.
Limitations
- Compression lags H.264 by ~40% at equal quality.
- Hardware decoders never adopted Theora.
- WebM (VP9/AV1) is the modern open-codec choice.

- Wikipedia demo video 5-50 MB
Quality & Compatibility
Resolution, frame rate and colour space are preserved end-to-end. If the OGV container does not support some MTS features (chapters, multiple subtitle tracks, DRM-protected streams), those are flattened or dropped with a warning. Hard-coded subtitles in the video frames always survive.
Tips for Best Results
- Embedded subtitle tracks convert between MTS and OGV when both containers support the same subtitle codec; otherwise burn the subtitles into the video first.
- For portrait (9:16) clips, make sure the OGV encoder preserves the correct display aspect ratio — some players default to 16:9 if SAR is ambiguous.
- Long recordings (over an hour) benefit from chapter metadata; OGV may not preserve MTS chapters — check before relying on them.
Frequently Asked Questions
Only when it has to. If the codecs inside MTS (usually H.264 or H.265 for video, AAC for audio) are accepted by OGV, we stream-copy — the bytes are repackaged into the new container with zero re-encoding and no quality loss. When the source uses a codec the target does not support, we transcode at a matching bitrate to keep the visual quality close to the original.
With stream copy, expect the job to finish in seconds to tens of seconds regardless of video length — the work is mostly rewriting the container. Transcoding is slower (roughly real-time: a ten-minute clip takes about ten minutes) because every frame must be decoded and re-encoded. The progress bar shows which mode applies.
Yes. Resolution, frame rate, colour space and bit depth are preserved by default; stream copy is literally bit-identical on these parameters. If you explicitly pick a lower bitrate or a different codec in Advanced, the output is rebuilt to those settings, but the default is always "match the source".
