AVCHD to OGG Converter

AVCHD to OGG — Vorbis or Opus Inside the .ogg File?

This tool pulls the audio track out of AVCHD camcorder footage and writes it into an OGG file — the H.264 video is discarded and you keep only the sound from a Sony or Panasonic clip. The real decision on this page isn't whether to extract; it's which codec fills the OGG container. By convention a .ogg file holds Vorbis (that is what the extension is reserved for), but the same Ogg container can also carry Opus, the newer and more efficient codec. The short answer: if you specifically need a .ogg file for open-source software, keep the default Vorbis; if efficiency matters more than the extension, pick Opus and accept a .opus file instead.

Vorbis vs Opus for an Extracted AVCHD Soundtrack

When to Pick Vorbis (stay on .ogg)

• A program, game engine, or pipeline specifically expects a .ogg file — Xiph reserves that extension for Vorbis, so this is the correct match.
• You're feeding an older open-source tool that decodes Vorbis but predates Opus support.
• You want the format the Ogg container was originally built around, with the widest reach across legacy Linux and FOSS software.
• You don't need the last few percent of compression efficiency and just want a clean, patent-free OGG.

When to Pick Opus Instead

• You care about file size at a given quality — Opus beats Vorbis at most bitrates and is dramatically better below 96 kbps, which suits a speech-heavy camcorder recording.
• The target is a current browser, app, or messaging platform where Opus plays natively.
• The recording is voice — a lecture, interview, or ambient narration — where Opus stays clean at 32-64 kbps.
• You're fine with the conventional .opus extension. If that's the case, convert AVCHD to Opus is the more direct route and names the file correctly.

How to Convert AVCHD to OGG

1. Upload Your AVCHD Stream File: Drag and drop your .MTS or .M2TS clip onto the page, or click "+ Add Files". Queue several clips to extract them in one batch with the same settings.
2. Pick a Quality Preset: Open Advanced Options and choose a Quality Preset under File Compression — Highest down to Lowest — or switch to Custom Bitrate, Constant Bitrate, or Variable Bitrate to set an exact rate. The OGG output defaults to the Vorbis codec.
3. Set Audio Channel or Sample Rate (optional): Leave Audio Channel and Audio Sample Rate on "Original" to copy what the camera recorded, or set Audio Channel to mono/stereo. If the clip carries 5.1 surround, choose stereo — it downmixes to two channels. Use Trim to keep only part of a long recording.
4. Convert and Download: Click "Convert" and download your .ogg file individually or as a ZIP. No sign-up, no watermark.

Frequently Asked Questions

Does this keep the video, or just the audio?

Just the audio. This is an extraction: the H.264 video inside your AVCHD clip is discarded and only the soundtrack is written into an OGG file. If you want to keep the picture too, convert AVCHD to MP4 instead, which re-encodes both the video and audio into a single playable file.

Will the OGG sound better than the audio already in my AVCHD clip?

Usually no, and it depends on how the camera recorded it. Most consumer AVCHD camcorders record Dolby AC-3 (Dolby Digital), which is already lossy — so extracting to OGG Vorbis (also lossy) is a lossy-to-lossy transcode that can come close to the source but can't regain detail AC-3 already discarded. Some professional models record uncompressed Linear PCM; because that source is lossless, extracting it to OGG is a clean first-generation encode, the same quality you'd get encoding Vorbis from a WAV master. Either way, keep the OGG bitrate at or above the source rate to keep any second-generation loss minimal — in our testing, a stereo AC-3 camcorder clip extracted to 192 kbps OGG Vorbis was hard to distinguish from the source in normal listening.

Should I put Vorbis or Opus in my OGG file?

By default this tool encodes Vorbis, which is what the .ogg extension is reserved for — pick that when a program specifically wants a .ogg file. Opus is the newer codec: it's more efficient and the Xiph.Org Foundation has recommended it over Vorbis since 2013, but it's conventionally delivered as a .opus file. So if you want Opus specifically, convert AVCHD to Opus names the file correctly. Use Vorbis for the literal .ogg extension; use Opus when efficiency matters more than the extension.

Can the OGG output keep my AVCHD clip's 5.1 surround sound?

In practice, no — it comes out as stereo. AVCHD AC-3 audio can carry up to 5.1 channels, and OGG/Vorbis the format does support multichannel, but this tool's Audio Channel control offers Original, mono, and stereo, so a surround source is most reliably handled as a two-channel mix here. If preserving every channel matters, extract to AAC instead, where multichannel is the supported path. For an ordinary recording you'll listen to in stereo, OGG at a healthy bitrate is a fine finish.

I only see folders on my camcorder card — which file do I upload?

AVCHD stores clips under PRIVATE/AVCHD/BDMV/STREAM/. Browse into that STREAM/ folder and upload the individual .MTS clip (it's .M2TS once copied to a computer). This tool takes the single stream file, not the whole card folder — uploading the top-level AVCHD directory won't work because it isn't a single media file. A file already labeled .avchd holds the same H.264 video with AC-3 or LPCM audio and extracts identically.

Should I just use MP3 instead of OGG?

If your goal is playback on the widest range of devices — an old car stereo, a basic media player, a phone — MP3 is the safer bet because it plays virtually everywhere, so extract to MP3 instead. OGG is the better choice when you specifically want an open, patent-free format or a tool that expects .ogg. For Apple devices and better-than-MP3 efficiency with multichannel support, AAC is another option.

How are my files handled, and is there a size limit?

Your AVCHD clip is uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public. The main practical limit is upload size and time rather than the extraction itself: an AVCHD clip carries full HD video alongside the audio, so a long recording can take a while to upload even though pulling out the soundtrack is quick.
