MPEG-2 is the DVD-and-broadcast video standard (ISO/IEC 13818, also known as H.262), usually carrying standard-definition footage in a .mpeg or .mpg file. AVCHD is the consumer HD camcorder format Sony and Panasonic introduced in 2006: H.264/AVC video with AC-3 or LPCM audio, wrapped in an MPEG-2 transport stream and saved as .mts or .m2ts. This converter transcodes the MPEG-2 video to the AVCHD (H.264) stream so it slots into an AVCHD-authoring tool or a camcorder/player library that expects that format.
One honest caveat up front: converting standard-definition MPEG-2 to AVCHD does not make the footage true HD. Upscaling stretches existing pixels — it cannot recover detail the original DVD or broadcast capture never recorded. AVCHD is just the output wrapper here, not a quality upgrade. If you only need a file that plays everywhere, MP4 (H.264) is simpler and more universal than AVCHD.

How to Convert MPEG-2 to AVCHD
- Upload Your MPEG-2 File: Drag and drop your
.mpegor.mpgfile onto the page, or click "Add Files." You can queue several clips and convert them with the same settings. - Pick a Quality Preset: The Preset control defaults to "Very High (Recommended)." Leave it there to preserve detail, or step it down to shrink the output — AVCHD output stays within the format's H.264 bitrate ceiling either way.
- Set the Resolution: Use the resolution presets or "Keep original." Note that picking a 1080p preset on standard-definition source upscales it; it does not add real detail, so "Keep original" is usually the honest choice.
- Convert and Download: Click "Convert" and download the
.mtsfile. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. No sign-up, no watermark.
Frequently Asked Questions
Will converting MPEG-2 to AVCHD turn my standard-definition video into HD?
No. AVCHD is an HD-capable format, but the conversion only re-encodes the pixels you already have. Standard-definition MPEG-2 (typically 720×480 or 720×576) can be stretched to a 1080p frame, yet upscaling cannot invent detail the original recording never captured. The result is an AVCHD-formatted file at HD dimensions, not genuinely higher-resolution footage.
Why is my AVCHD audio re-encoded instead of copied?
AVCHD is a strict specification that allows only Dolby AC-3 or uncompressed linear PCM audio. If your MPEG-2 file carries MP2 audio — common on DVDs and broadcast captures — it has to be re-encoded to a compliant track so the output plays in AVCHD-aware players and authoring tools. MPEG-2 that already uses AC-3 is closer to spec, but a re-encode may still happen to meet AVCHD's sampling and channel rules.
Is the .mts file the converter produces a playable AVCHD disc?
Not on its own. A bare .mts or .m2ts is just the AVCHD video stream. For camcorder or Blu-ray player playback you need the full BDMV/AVCHD folder structure — the BDMV and STREAM directories with their index and playlist files — which an AVCHD-authoring application builds around the stream. The file from this converter is the stream you feed into that authoring step or import into a non-linear editor.
Should I just convert MPEG-2 to MP4 instead?
For general playback and sharing, yes. MP4 with H.264 video plays on virtually every phone, browser, and TV without the AVCHD spec's audio and folder-structure constraints. Choose AVCHD only when a specific tool, camcorder, or disc-authoring workflow asks for it; otherwise convert MPEG-2 to MP4 is the simpler target.
Does AVCHD compress better than the original MPEG-2?
Usually, yes. AVCHD uses H.264/AVC, which is a generation newer than MPEG-2's H.262 and is more efficient at a given quality. In our testing, re-encoding a standard-definition MPEG-2 clip to AVCHD at the same visual quality produced a noticeably smaller file, because H.264 packs the same frames into fewer bits. The trade-off is that any re-encode is lossy, so keep the quality preset high if you plan further editing.
Can I edit the AVCHD output in Premiere Pro or DaVinci Resolve?
Yes. AVCHD's H.264 stream in an MPEG-2 transport stream is a standard import format for Premiere Pro, Final Cut Pro, and DaVinci Resolve, which is one of the main reasons people target it from a camcorder workflow. If your editor prefers an all-in-one container, an AVCHD-to-MP4 conversion afterward keeps the H.264 video while swapping to the more editor-friendly MP4 wrapper.
