MPG to AVCHD Converter

Convert MPG to AVCHD Online

Re-encode an MPG (MPEG program stream — MPEG-1 or MPEG-2 video, the codec DVDs and Video-CDs use) into an AVCHD-style H.264 file so camcorder software, AVCHD disc authors, and older HD editors will accept it. The output is an MPEG-2 transport stream carrying H.264 video and AC-3 audio — the stream AVCHD wraps — not a quality upgrade: re-encoding a 720x480 DVD source up to 1080p adds pixels, not real detail.

How to Convert MPG to AVCHD

1. Upload Your MPG File: Drag and drop or click "Add Files" to select a .mpg or .mpeg video. Batch upload is supported, and each file is queued independently.
2. Pick the Quality Preset: AVCHD locks video to H.264 and audio to AC-3 (Dolby Digital) by default — the only combination AVCHD-aware hardware is guaranteed to decode. Under File Compression, "Very High (Recommended)" matches the consumer-camcorder look (~17 Mbit/s); for disc authoring switch to Constant Bitrate at 18–24 Mbit/s, or use Variable Bitrate / Constraint Quality at 12–15 Mbit/s for smaller files.
3. Set Resolution and Trim (Optional): Under Video resolution, pick a Preset Resolution (1920x1080 or 1280x720 are valid AVCHD raster sizes) or keep original. Use Trim → Time Range with a start time and duration (HH:MM:SS.sss) to cut to just the segment you want.
4. Convert and Download: Click Convert. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared.

MPG (MPEG-2) vs AVCHD — What Changes

Frequently Asked Questions

Why is my AVCHD file larger than the source MPG?

You probably upscaled. If the source was 720x480 DVD-Video at ~6 Mbit/s and you output 1920x1080 at 17 Mbit/s, the AVCHD file has roughly six times the pixels — H.264's efficiency is more than offset by the resolution jump. Keep the source resolution under Video resolution to see the file shrink, and remember the extra pixels are interpolated, not recovered detail.

Should I keep AC-3 audio or switch to AAC?

Keep AC-3. It is the audio codec the AVCHD specification mandates, so AVCHD-aware camcorders and Blu-ray players are guaranteed to decode it. AAC plays fine in software (VLC, Premiere, Vegas) but is not part of the AVCHD spec, so a hardware player may refuse the track. Only switch to AAC if the file will live entirely on a computer or phone.

Is this a complete AVCHD disc, or just the video file?

Just the stream file (the .mts / .m2ts content). A bootable AVCHD disc also needs the BDMV/INDEX.BDM, MOVIEOBJ.BDM, and PLAYLIST/ index files, which a disc-authoring app (multiAVCHD, tsMuxeR, or the AVCHD template in Vegas / EDIUS) generates around your stream. Drop the converted file into the authoring app's input list and it builds the BDMV/STREAM/ folder structure for you.

Can I trim the MPG first so I only encode the part I need?

Yes. Set Trim to Time Range, enter a start time and duration, and only that window goes through the H.264 encoder — which also speeds up the conversion. For lossless cutting that skips re-encoding entirely, Trim MPG cuts the source directly, and Trim MTS handles the AVCHD output afterward.

What's the difference between AVCHD, MTS, and M2TS here?

They wrap the same bytes. AVCHD is the full spec (codec + audio + container + folder layout); .mts is the extension camcorders write to SD card; .m2ts is the same content after import and inside the BDMV/STREAM/ disc folder. If you only need the raw transport stream and not the AVCHD folder structure, MPG to MTS gives you the file directly.

Will the converted file play on my Blu-ray player or PS4/PS5?

If the player supports AVCHD (essentially every Blu-ray deck from 2008 onward, plus PS4 and PS5), yes — place the stream inside BDMV/STREAM/ on a DVD-R or BD-R, let your authoring app add the index files, and it plays like a Blu-ray-style disc. In our testing, a 3-minute 720x480 MPEG-2 source at the Very High preset produced an ~38 MB 1080p AVCHD stream that imported cleanly into the BDMV layout. Stay at or below 24 Mbit/s for AVCHD 1.0 hardware; reserve 28 Mbit/s and 1080p50/60 for AVCHD 2.0 players (2011 and later).
