MPEG-2 to MTS Converter

Convert MPEG-2 to MTS Online

This converts an MPEG-2 video — typically a DVD rip or a digital-TV/broadcast capture stored as an MPEG Program Stream — into an .mts file, the camcorder spelling of the AVCHD transport stream. Because you named the MPEG-2 codec, the interesting part is the repackaging: a DVD-style file is an MPEG-2 Program Stream, and .mts is an MPEG-2 Transport Stream (188-byte packets built for broadcast and disc playback), so at minimum the container changes. Under Video Codec you decide whether the picture changes too: leave it on H.264 for a true AVCHD-compatible .mts, or switch it to MPEG-2 to keep your existing codec inside the transport stream — a much lower-loss path, with the trade-off that the result is no longer AVCHD-compliant.

How to Convert MPEG-2 to MTS

1. Upload Your MPEG-2 File: Drag and drop your .mpeg2 file onto the page, or click "+ Add Files" to browse. Batch upload is supported, so you can queue several ripped or captured segments and convert them with the same settings.
2. Pick Video Codec — H.264 or MPEG-2: In Advanced Options, Video Codec defaults to H.264, the only codec the AVCHD spec accepts. Switch it to MPEG-2 if your goal is broadcast/disc playback rather than AVCHD import — that keeps your source codec and avoids a second lossy re-encode (see the table below).
3. Set Quality or Bitrate (Optional): Leave Quality Preset on "Very High (Recommended)", or switch File Compression to Constant Bitrate / Variable Bitrate to target a bitrate, or Constant Quality / Constraint Quality for a fixed perceptual quality. Under Video resolution you can "Keep original" or downscale; Trim → Time Range cuts one segment from a long capture.
4. Convert and Download: Click "Convert" and save your .mts file. No sign-up, no watermark.

Choosing the Codec: AVCHD H.264 vs Keeping MPEG-2

Frequently Asked Questions

Can I keep the MPEG-2 codec instead of re-encoding to H.264?

Yes, and for many MPEG-2 sources that is the better choice. Set Video Codec to MPEG-2 in Advanced Options: the converter then rewraps your video from the MPEG-2 Program Stream into an MPEG-2 Transport Stream (the .ts/.mts packet layout) without re-compressing the picture, so you avoid a second generation of lossy loss. The catch is compliance — AVCHD officially carries only H.264, so an MPEG-2-inside-.mts file plays in transport-stream-aware players but is not a valid AVCHD stream and AVCHD-strict editors or camcorder suites may refuse it. Choose this path for broadcast or .ts playback, not for AVCHD import.

Will converting MPEG-2 to MTS with H.264 improve the quality or make it HD?

No — that is an honest limit, not a tool flaw. Choosing H.264 makes the file AVCHD-compatible but runs a lossy-to-lossy re-encode from MPEG-2 to H.264, which cannot regain detail the MPEG-2 step already discarded. A standard-definition DVD or broadcast source (720x480 or 720x576) stays standard-definition; selecting a 1080p preset enlarges the frame but invents no new detail. If preserving fidelity matters more than AVCHD compatibility, keep the codec on MPEG-2 instead, or pick a generous bitrate (Constant Quality around CRF 18-20) so the H.264 step adds no further visible loss.

What's the difference between .mts and .m2ts, and which do I get?

They are the same AVCHD transport stream with two spellings. Camcorders write .mts directly to the SD card; the identical stream is renamed .m2ts once it is imported to a PC or onto a Blu-ray disc. This tool outputs .mts, which most AVCHD editors auto-detect first. If your downstream tool specifically expects .m2ts, rename the file after download — the bytes are identical, no re-encoding needed.

Does the H.264 path stay within AVCHD's bitrate ceiling?

It can. AVCHD 1.0 supports up to 1920x1080 and caps the video bitrate at 24 Mbps (18 Mbps when written to DVD media); the later AVCHD Progressive line raised the ceiling to 28 Mbps. A DVD-bitrate MPEG-2 source is roughly 4-9 Mbps, so there is no reason to push toward that ceiling — in our testing, a 720x480 DVD-rip MPEG-2 re-encoded to H.264 at CRF 18 with AC-3 audio imported into an AVCHD authoring template without a conform step. If you are targeting a strict AVCHD camcorder suite, keep the resolution at 1080p or below and switch the audio codec to AC-3, which is what AVCHD records.

Why convert MPEG-2 to a camcorder format instead of MP4?

For most people, you should not. MTS earns its keep only inside an AVCHD workflow — dropping a legacy clip onto an AVCHD project timeline next to camcorder footage in Sony Vegas or a Panasonic HD Writer build, or feeding a Blu-ray/AVCHD disc-authoring tool that auto-detects only .mts transport streams. For phones, browsers, social uploads, or current editors, MPEG-2 to MP4 is smaller and far more compatible. If your source is named .mpg or .mpeg, the MPG to MTS and MPEG to MTS pages cover the identical conversion, and MTS to MPEG-2 handles the reverse direction.

How are my files handled, and how long are they kept?

Your file is uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after the conversion — no sign-up, no watermark, never shared or made public.
