Supports: MTS
MTS is the AVCHD container your Sony, Panasonic, Canon, or JVC camcorder writes — H.264 video and AC-3 audio in an MPEG-2 transport stream. OGV is Xiph.Org's open Ogg video format, the royalty-free wrapper of the pre-H.264 web. This tool re-encodes your camcorder footage into an Ogg file, defaulting to VP8 video with Vorbis audio (you can switch the video track to Theora). Be aware this is a fading target: the Theora codec most people associate with .ogv has been pulled from modern browsers, so unless a specific legacy pipeline expects an Ogg file, convert MTS to WebM for the modern open successor or convert MTS to MP4 for the most universal result.
.mts clips onto the page, or click "Add Files" to browse. Files straight off an AVCHD camcorder's BDMV/STREAM folder work, and you can queue a whole shoot to convert with the same settings..ogv file individually or as a ZIP. No sign-up, no watermark.| Property | MTS (AVCHD) | OGV (Ogg video) |

For almost everyone in 2026, WebM is the better target. OGV was the open web's video format before H.264, but the Theora codec associated with it was removed from Chromium (announced October 2023, disabled by default in Chrome 120 that December) and dropped by Firefox in version 130, and Safari never supported it. So an .ogv no longer reliably plays in a browser. The one solid reason to make an OGV is a legacy open-source toolchain or an old HTML5 fallback system that specifically expects an Ogg file. If your goal is to embed camcorder footage on a modern site, convert MTS to WebM (VP9/AV1) instead — it's the open successor and plays everywhere current.
Yes, to a degree, and it's worth understanding why. Your MTS holds H.264, a modern, efficient codec; both Ogg video options here — VP8 and especially Theora — are older and less efficient. Re-encoding H.264 into them is a lossy-to-lossy transcode going backward in efficiency, so to hold the same visual quality the output needs a higher bitrate, or you accept some quality drop at a matched size. Keep VP8 (the default) rather than Theora for the cleaner result, leave Quality Preset high, and keep the original MTS if you might need full fidelity later — lossy re-encoding is not reversible.
Not by default — it outputs VP8 video in the Ogg container, because VP8 is more efficient than Theora and still royalty-free. Theora is available under Video Codec if a specific legacy player or pipeline requires classic Theora-in-Ogg, but pick it deliberately. Either way the audio is re-encoded from the MTS's AC-3 or LPCM track to Vorbis, the standard Ogg audio codec. In our testing, a 60-second 1080p AVCHD clip re-encoded to VP8/Vorbis OGV at the default quality stayed visually close to the source while landing smaller than the original MTS.
AVCHD camcorders record AC-3 (Dolby Digital), usually around 256-384 kbps, or uncompressed LPCM. Ogg doesn't carry AC-3, so the audio is decoded and re-encoded to Vorbis, the native Ogg audio codec. For camcorder dialogue and ambient sound a default-quality Vorbis track is transparent. If the source has a 5.1 surround track, the primary track is kept and downmixed to stereo.
Your MTS is uploaded over an encrypted connection, converted to OGV 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. On a big AVCHD batch the practical limit is upload time and connection speed, not a per-file cap.
