Free online MTS to OGG converter

Source format overview

MTS is a video container format commonly associated with AVCHD camcorder recordings. It is used by consumer and prosumer cameras from brands such as Sony, Panasonic, and Canon to store high-definition video, usually with H.264/AVC video and AC-3 or AAC audio. MTS files are typically found on camera memory cards or imported from video shoots, and they are mainly used for preserving full-quality camera footage before editing or archiving.

Target format overview

OGG is a container format best known for audio, especially when paired with the Vorbis or Opus codecs. It is open, patent-friendly, and widely supported in media players, web tools, and open-source software. OGG is commonly used for music, voice recordings, podcasts, and other compressed audio distribution where a good balance of quality and file size is important.

How to perform the conversion

Because MTS is a video format and OGG is usually an audio container, the conversion normally means extracting the audio track from the video and saving it as an OGG audio file.

1. Open the MTS file in a converter or media editor that supports AVCHD input.
2. Choose OGG as the output format.
3. If the tool asks for codec settings, select Vorbis or Opus for the audio codec.
4. Start the conversion and save the resulting file.

For desktop software, FFmpeg is one of the best tools for this task because it handles MTS reliably and can export OGG audio directly. A typical command is ffmpeg -i input.mts -vn -c:a libvorbis output.ogg. The -vn option disables video, so only the audio is kept. If you prefer Opus, you can use ffmpeg -i input.mts -vn -c:a libopus output.ogg when your player or workflow supports Opus in an OGG container.

If you want a graphical workflow, open the file in a program such as VLC, Audacity with FFmpeg support, or another editor that can import MTS, then use File → Export or File → Convert and choose OGG as the output. You can also convert the file on 101convert.com for free, without installing any software.

Quality and compatibility notes

MTS often contains high-bitrate audio, so the final OGG file may be much smaller than the source. However, if the original audio is already compressed, converting it again to OGG can cause some quality loss. For best results, choose a moderate bitrate such as 160 kbps or higher for music, and lower settings for speech if file size matters more than fidelity.

Keep in mind that OGG is primarily an audio container. If you need to preserve the video from the MTS file, OGG is not the right target format. In that case, use a video format such as MP4 or MKV instead. Also note that some players support OGG Vorbis more broadly than OGG Opus, so compatibility may depend on the device or software you plan to use.
