MTS to MPEG Converter

Convert MTS to MPEG Online

MTS is the AVCHD transport stream your Sony or Panasonic camcorder records — H.264 video at up to 1920x1080 wrapped in an MPEG transport stream. MPEG (the long form of the .mpg extension) is the older MPEG-1/MPEG-2 Program Stream that DVD-authoring tools and legacy playback hardware expect. This converter re-encodes MTS into an MPEG file and lets you pick the codec, resolution, and audio track so the output matches whatever old device or DVD workflow needs it.

How to Convert MTS to MPEG

1. Upload Your MTS File: Drag and drop your .MTS clip onto the page, or click "Add Files" to browse. Queue several clips and they convert with the same settings.
2. Set the Video Codec to MPEG-2: Open the options and choose MPEG-2 — the codec DVD players and most legacy MPG/MPEG workflows expect. MPEG-1 is available for very old targets but caps quality and resolution.
3. Set Quality Preset and Video Resolution: Pick a Quality Preset (the default is "Very High (Recommended)") and, for DVD authoring, drop Video Resolution to a standard-definition Preset Resolution. Set Audio Codec to AC3 for DVD or MP2 for the broadest legacy compatibility.
4. Convert and Download: Click Convert and download your MPEG file. No sign-up, no watermark.

Frequently Asked Questions

Is .mpeg the same format as .mpg?

Yes. .mpeg and .mpg are the same MPEG-1/MPEG-2 Program Stream — the only difference is the extension length. Early Windows required three-character extensions so it used .mpg, while Mac kept the longer .mpeg; both carry identical video and audio data and play the same way. This converter outputs the .mpeg spelling, which you can rename to .mpg with no change to the file.

Will I lose quality converting MTS to MPEG?

Some loss is unavoidable because you are re-encoding from efficient H.264 (inside the MTS) into less-efficient MPEG-2 (inside the MPEG). At a high enough bitrate the output can look very close to the source, but it will not be a lossless copy. If you also downscale to DVD resolution, the drop from 1080p to 720x480/576 is part of that format change, not a converter limitation. To keep your footage at full quality for modern playback, convert MTS to MP4 instead — H.264-in-MP4 avoids the re-encode penalty.

Is the MPEG output DVD-compatible?

It can be, if you set it up correctly. DVD-Video is standard definition only: 720x480 at 29.97 fps for NTSC or 720x576 at 25 fps for PAL, with MPEG-2 video and AC-3 (or MP2) audio. Choose MPEG-2 as the Video Codec, drop Video Resolution to a standard-definition preset, and pick AC3 audio. A full-HD MPEG will be rejected by DVD-authoring software, so the downscale is required, not optional.

Which audio codec should the MPEG use?

For DVD-bound output choose AC3 (Dolby Digital), which AVCHD already uses and DVD players expect. MP2 is the alternative for the broadest legacy compatibility, and MP3 is available where a player supports it. The default keeps a standard MPEG-compatible track so older hardware can read it.

How large will the MPEG file be?

Expect it to be larger than the MTS at matching quality — that is the efficiency gap between H.264 and MPEG-2, not a bug. In our testing, a 60-second 1080i AVCHD clip re-encoded to standard-definition MPEG-2 at the default Very High preset produced roughly a 40 MB MPEG; keeping full 1080p resolution pushes that higher. Lower the resolution or bitrate if file size matters more than fidelity.

What happens to my file after I convert it?

Your MTS is uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion. Files are never shared or made public, and there is no sign-up or watermark. Going the other direction — MPEG back into an AVCHD stream — is handled by MPEG to MTS, and the .mpg-spelled equivalent of this tool is MTS to MPG.
