Free online MTS to OGV converter

Source format overview

MTS is a video container format commonly used by AVCHD camcorders and other consumer video cameras. It usually contains H.264/AVC video with AC-3 or LPCM audio, and it is often found on memory cards after recording high-definition footage. MTS files are widely used for camera originals, home videos, event recordings, and footage that later needs editing or archiving.

Target format overview

OGV is a video file format based on the Ogg container, typically used with open codecs such as Theora for video and Vorbis or Opus for audio. Its main advantages are open standards, broad support in web and cross-platform software, and good suitability for free software workflows. OGV is often used for web video, embedded playback, and distribution where open formats are preferred.

How to convert MTS to OGV

The most reliable method is to use FFmpeg, which can read MTS files directly and encode them into an OGV-compatible stream. If you prefer a no-install option, you can convert the file on 101convert.com for free without installing any software.

Using FFmpeg on the command line:

1. Install FFmpeg if it is not already available on your system.
2. Open a terminal or command prompt in the folder containing your .mts file.
3. Run a conversion command such as:

ffmpeg -i input.mts -c:v libtheora -q:v 7 -c:a libvorbis -q:a 5 output.ogv

4. Play the resulting output.ogv file in a compatible media player to verify the result.

What the command does: libtheora encodes the video into Theora, libvorbis encodes the audio into Vorbis, and the quality values control the balance between file size and fidelity.

Using desktop software: Some editors and transcoders, such as VLC, HandBrake, or Shotcut, can also export to OGV or to Theora/Vorbis-compatible settings. In such tools, the usual workflow is to open the MTS file, choose an OGV or Theora preset, then use File → Export or Convert/Save depending on the program.

Quality, compatibility, and limitations

MTS to OGV is a re-encoding conversion, not a simple container change. That means the video and audio are usually decoded and encoded again, which can cause some quality loss compared with the original camera file. To minimize degradation, start from the highest-quality source available and use moderate quality settings.

OGV is less common than MP4 for modern consumer playback, so compatibility may be limited on some devices, TVs, and mobile apps. It is best suited for open-format workflows, web publishing in supported environments, and archival or software projects that specifically require Ogg/Theora.

If your MTS file contains interlaced video, conversion may also require deinterlacing for best playback quality. In addition, some MTS files use audio codecs or metadata that are not preserved exactly during conversion, so check the output if you need subtitles, chapters, or camera-specific information.
